Description

Wire brush bit convolution rig

Technical field

The utility model belongs to the Foundation Design technical fields such as traffic, municipal administration, water conservancy, building, is specifically related to a kind of wire brush bit convolution rig.

Background technology

Foundation pile is widely used as the basis of building, and especially in the building structure such as bridge, house, it is world-famous for advantages such as of fine quality, inexpensive, flexible, easy, strong adaptabilities.Engineering based on foundation pile, its hole forming method is more, mainly contains boring, punching, revolves and dig.The quality that drilling scheme is selected directly decides the effect of engineering construction, and how to choose the drilling scheme of foundation pile, must consider the geological conditions at bridge location place.

But, no matter adopt which kind of construction method, because it belongs to " concealed work ", risk is still larger, in work progress, drill bit to drop in wellhole or drill bit is embedded in the medium situation of wellhole for a long time all the time all in generation for various reasons, for this reason people's utility model tool and method of all salvaging drill bits in practice.Such as, recovery hook method, salvage fork method, salvage around-France, salvage kink method, electromagnetism iron processes, underwater demolition method, diver's Diving Clevis method etc., also have 201020519143.0 " bit-fishing units " of the auspicious utility model of Wang Ming, 02294628.4 " drill extractor of bored pile " of Jiang Nan utility model, 200810124473.7 " drill extractor of bored pile " etc. of the utility models such as Forth Engineering Of Zhongtie Bridge Bureau Co., Ltd Pan Jun.Even, drop in wellhole to prevent drill bit, be representative with Zheng Wanjiang etc., directly make an issue of from " drill bit ", suppose that drill bit has dropped in wellhole in advance, utility model 200620158612.4 " Well drilling specialized bit of salvagable quills ", Baker Hughes Inc is utility model 200780021418.9 " surface textures for Earth boring bits " etc. also.

Here, people can't help asking, come out to the utility model of these instruments, method from foundation pile, bury drills, fall the problems such as brill, bit freezing and solve actually? answer is apparent, is never resolved! Question closely reason, above-mentioned numerous tool and method also could not solve question of substance! Only can solve some relatively simple minor issues in other words, comparatively challenge can not be solved at all, there is no compliance comparatively widely, still can as case.

We might as well be illustrated by an example: certain speedway the 6th contract section, there is a grand bridge, in its water, foundation pile is diameter 180cm, dark 92m friction pile (depth of water 7m), geological conditions is for from top to bottom: 7m powder sandy soil+28m medium coarse sand (local presss from both sides stiff stone)+36m sand gravel+21m strong-weathered rock, in view of stake footpath is greatly and too dark, the method for preferred impact holing.When the punching degree of depth reaches 63m, wire rope is unexpected to break from the position be connected with tup, causes the heavy impact tup of 8t to drop in wellhole.So start difficult salvaging, salvaging process is full of twists and turns, in brief, has asked superiors, has lasted 27 days, and use up various tool and method and all fail, reason is:

(1) be really also repeatedly hooked to recovery hook, but promote not come up.Adopt the crane of 85 tons not only to promote motionless at that time before this, narrowly cause the accident of crane overturning; The hoist engine using 2 20t afterwards instead draws simultaneously, also fails; Shape steel bracket jacking used by the jack using 4 200t more afterwards instead, and top, the 45# I-shaped steel capital has been out of shape, wire rope all pushes up to have broken several and also do not push, and just sends huge ear-piercing sound!

(2) once once again installing convolution rig at that time to carry out Pump breath countercirculate and change slurry, clear hole, and attempting to reduce mud balance, the sediment that minimizing drill bit deposits and absorption affinity thereof, but of no avail!

(3) also asked professional diver, because the degree of depth is comparatively dark, no one dares risk!

(4) also drafted underwater demolition scheme, but how explosives etc. accurately deliver to position, are not sure, and also count out.

(5) also someone makes suggestions, and only has and has done by " underlying rule ".Namely continue construction, look at how deeply can also rush, where where drilling depth calculated, and directly fakes on stake is long, improve ties with, cheat and reach a standard! Here illustrate, after there is this situation, owing to substantially cannot continue down to construct (have the huge monster of an iron and steel material quality in wellhole again, which type of instrument just can be smashed frustillatum and keep wellhole not collapse), build owner not allow again to destroy this stake, design for change is " shoulder pole stake ", has many units substantially all to do by " underlying rule " thus in actual life! Can imagine, this causes much hidden danger to workmanship, causes nearly loss to country! But there is the people of intuitive knowledge not allow such thing to occur.

(6) thought by a large amount of, various methodologies is taked to put forward the reason of motionless tup, because tup " card " is where? otherwise be that the time is too of a specified duration, is deposit too heavy above tup? otherwise that tup and the suction at the bottom of hole are too large? in fact, because sediment glues close, plug the passage with drill bit top mud at the bottom of hole, namely the gap between hole wall and drill bit is very little, due to the mud on drill bit top and the slurry channel of drill bit bottom almost blocked, dynamic drill bit is promoted to be equivalent to pull up " uplift pile ", thus the drill bit of being not only of having promoted drill bit to need to overcome is conducted oneself with dignity, frictional force between drill bit and hole wall, also comprise the pressure etc. that drill bit top is about the mud generation of 60m, this power is through scientific algorithm, up to more than 100 tons, sometimes hundreds of ton is even reached, therefore the moment that dynamic drill bit will be promoted to need promotes power very large, why this namely adopts crane to promote can not the cause for the success.
