Добрый день дамы и господа
Роторный и шнековый способы бурения. Их отличия.
В зависимости от глубины бурения и типа почвы компания “БухтехСервис” применяет 2 способа бурения.
Роторный способ бурения. Выполняем с помощью передвижной буровой установки УРБ–2а2 на шасси ЗИЛ–131. Применяемый инструмент – шарошечные долота с широким диапазоном диаметров 75–300мм. Благодаря универсальности этого способа с легкостью разрушаются мягкие и твердые горные грунтовые слои.rotornoe-burenie
Вращательную мощность ротор направляет долотом на рабочую колонну. Для удаления разрушенной породы делают промывку через буровой насос с помощью специальных полимеров. После того, как пройдена бурением первая часть скважины, опускают первую обсадную колонну (кондуктор), чтобы перекрыть слабые неустойчивые породы и верхние водоносные горизонты, производят гидроизоляцию затрубного пространства, закачивают в него приготовленную смесь с цементом. Бурение скважины продолжается долотом меньшего диаметра внутри обсадных труб до отмеченной глубины, затем в скважину опускают следующую обсадную колонну или эксплуатационную колонну, которая будет находиться в водоносном слое.
Роторный метод обладает высокой продуктивностью и способностью обрабатывать любой тип почвы, но также и более дорогостоящий нежели шнековый.
Шнековый способ бурения популярен среди населения по причине своей простоты и доступности. Его используют в рыхлой почве и грунте средней твердости. Отличительным в технологии пробуривания шнеком является то, что отсутствует необходимость в промывке водой, так как снятие набившихся разломанных слоев почвы осуществляет шнек. Все дело в скорости обрабатывания. Но если в почве попадутся камни, использование шнека станет проблематично. Рационально использовать этот метод при строительстве скважин малой глубины в почве.
Несомненный плюс в пользу способа с применением шнека – доступная стоимость.
Технология шнекового бурения позволяет добиваться глубины бурения до 40 метров, в том числе и зимой в сильные морозы. Гораздо более глубокие скважины бурят посредством роторного способа. Он справляется с любым грунтом, в то время как шнековый способ позволяет обрабатывать только сухие и не самые твердые виды почв.
У каждого способа свои плюсы и минусы. При выборе способа бурения для своего случая нужно учитывать тип почвы в своей местности, а также климатические условия.
MY STORY
(Stephengag, 12. 6. 2021 22:35)
This is a story based off of one of my friends and I. He is my best friend in the entire world. I wouldnt trade what we have for anything.
Adam is my best friend. He is about 63 and is kind of tan considering its always cold here. Hes skinny but has a lot of muscle. He is the star player on our schools basketball and baseball teams. He is so super nice to everyone and is very smart. Hes in a lot of my classes. Hes kind of shy and quiet too.

Gray Rock
(LeroyLox, 12. 6. 2021 15:37)
I just dont understand what happened? Jax spoke to Tyler as they rode in the front of the bus on their way back to gray rock. They continued the discussion as the boys complained about not getting to see the girls and such. The whole bus ride back was noisy. As the bus pulled into the parking lot and the cadets made their way back to the dorms Jax and Tyler made their way to the armory to check in their weapons. Jax spoke as they walked I know you dont agree with all the behind the scenes stuff he motioned with his fingers as if quoting. But I also have seen how you look and act around that cadet…whats his name…max.

Caravan of love
(Chesterprinc, 12. 6. 2021 9:22)
God I need a cigarette! I gasped as I collapsed, exhausted, at the top of the small mountain my team had just hiked up in the Lake District.
Youre supposed to be setting us a good example. Khalid laughed as he flopped down next to me quickly followed by his two schoolmates.
Fu…To Hell with that! I laughed, I deserve one after a walk like that.
Still laughing at me puffing and panting the boys whispered something, then Khalid turned to me and asked nervously; Do you really want a smoke?

Turning His Angel Into A Slut
(StephenTox, 12. 6. 2021 4:08)
I tried so hard to remember what had gotten me here.Could it have happened that first night in the movie theatre?Could it have been when he was fucking me?Could it have been in the theatre today?These are all questions that went through my head.
The first night we went to the movies turned out to be a most memorable one.My Daddy wanted a blow job.He didnt care who was around, or if they saw, he only wanted to release and release he did.He unzipped his pants and pulled them down away from his cock then took his hand and wrapped it around the back of my neck.

Bright and Early
(GeorgeHub, 11. 6. 2021 23:07)
Anya lay on her bed, staring at the ceiling of her moderately-sized dorm room. Her digital alarm clocks LCD display burned a crisp 4:05 AM in the darkness. In two hours and a half she would have to go to class. Her music player was still operating, singing out Pink Floyds later, more ambient sounds. In her head, she went over all the homework she had and every project due withing the next three weeks. Everything was according to schedule. She continued to stare, thinking about how she would make the most of the first weekend her roommate, Tara, was gone.

First gay experience
(Jesusfounk, 11. 6. 2021 18:13)
My dad and I had always been close in what some people would call an odd way. My mom passed away when I was 3 so dad basically raised me by himself. Growing up we did everything together. Cuddled (sometimes he would be naked) and watched sports, went to games, he would give me baths, and some other stuff. But as I got older I noticed how dad would start to look at me more and more and for longer amounts of time.

Seductive Spin Class
(WilliamDup, 11. 6. 2021 4:43)
My 4 p.m. Timberlake spin class is about to start and all I can think about is the path my life has taken. I, Benjamin, a once bad-boy with a fetish for bees used to brothel hop and go to matinees alone to use only the most buttery of popcorn to relieve myself in times when my flesh light was stolen. It wasnt until I hit rock bottom half way through what I thought was flight of the bumblebees, when I realized I was masturbating to Akeelah and the Bee and tearing up along with Laurence Fishburne as Akeelah correctly spells logorrhea, when I decided to turn my life around. Trading matinees for daily spin classes, I have devoted my life to healthy eating, exercise and the LA lifestyle. Although my life is now back on track I cant help but have cravings for large breasts, dripping pussies, and holding my cock watching it blow with the force of one thousand fire hydrants – now thats some good shit.

This is my first story hoped you like reading it as much as I enjoyed writing it. I appreciate any compliments and/or tips. Tell me if you want me to continue this story. Thanks <3
Every day was different when working at the police station, but Carol was still taken aback by what she discovered when she walked into work. She was surprised when she walked into the main area to be greeted by the chief inspector Stan, who was standing next to a woman of early 30s, wearing a red latex outfit that showed an ample amount of her cleavage, which Carol could only guess was DD.

The air conditioner on my old Honda Prelude had died along with the radio, and now I was soaking in the last breaths of the cold air. Just before the temperature in that hot box became unbearable, a pale girl on a bicycle appeared, my salvation.
Jesus Tabitha, you said youd be home 2 hours ago. Im gonna need a jump now, I complained as I slammed my car door. Well, the skinny red head started, locking her pink mountain bike to the rack, that is what youre here for isnt it? I gave only an amiable smile as the double entendre wouldnt dawn on me for another moment. Well where the heck have you been?

Different Dads, Different Daughters
(Donaldsex, 10. 6. 2021 10:52)
The next morning Ryan woke to the definite sensation of something warm, wet, and wrapped around his hard and throbbingcock. Peeking under the covers his curiosity was rewarded with the deliriously sexy sight of Patty sucking him while she was in a state of pleasure and happiness. Mind you, if hed taken the time to look, he could have figured it out by the up and down motion of the covers, or by the air movement that her bobbing created. But just that lustful sight was worth the effort of his exploration.

Marcia and Ted were into their favorite bar on a Friday night, drinking and dancing to a local rock band.Two of their friends, Larry and Joan, walked in and joined them.The two couples drank well into the night and when the bar closed down, Marcia and Ted suggested that they continue the party at their house.
Ted turned on more rock music at the house and asked if Larry and Joan would like to smoke some weed to keep the party going.The four of them sat around and got high and eventually, the topic of conversation turned to sex.

My Sexual Awakening
(Larryasted, 9. 6. 2021 23:54)
I am Mike, 16, I do the normal things a teenage guy does, video games, hanging out with friends, sports, no girl friend fanaticize about sex.And noI have not really been on a date yet. I guess you could classify me as a jock, just not the baseball, football or basketball type. I did like cross country and really liked the long distance runs we had to do.Most of the other guys on the team hated running anything over 6 or 8 miles. Me, I felt I was just getting started at 6. It didnt matter if it was spring or winter season. It was just great to be outside. So I was definitely in shape but not muscular.

My name is Rudy and my homie Max has this banging sister, her names Sarah. Shes about 411 with big ol jugs for breast and and a decent sized ass. When she really started catching my attention was when I got expelled and had to go to a charter school. Her parents had agreed for me to be dropped off at theyre house in the mornings so I can walk to school from there I spent about 1 hour there every morning. But sometimes Sarah would open the door for me. And shed always be in her pajamas without a bra and some tight shorts that showed half her ass.

THE WHORE
(Jeffreyrog, 9. 6. 2021 9:38)
Now Open For Business
When I went to work on Brendas garden one morning there was a strange car in the driveway. This was a car I had seen somewhere before. I put it out of my mind and went about my chores weeding a flowerbed.As usual I was wearing my special ‘gardeners uniform, a pair of cut off jeans, no shirt just the shorts. I wore no underwear either because that was the way my ‘client wanted me.

Summer Time
(Angelmum, 9. 6. 2021 3:22)
Well as I was checking out the bank lines and waiting for Mark to return I reflected on just what had happened.I would have never imagined the feelings I had at that moment.I didnt know if I was gay or what but I couldnt deny that what me and Mark had done was probably the greatest thing I have ever done in my short life.As I sat there nursing my beer I relived the feeling of Marks cock in my mouth, hard yet velvety at the same time.And then the way Mark took me in the ass for the first time of my life.What ever happened next I knew that this would always be a time that I would remember for the rest of my life.

Jolene felt a burning sensation
(SergioBap, 8. 6. 2021 21:38)
Jolene felt a burning sensation directly above her left nipple.It was a quick heat followed by a dull throb.It moved across her chest and ended just above her right nipple.She knew better than to cry out, or make any noise more than a low moan.
