Description

A kind of drilling tool suitable for soft soil foundation Man-Hole digging
Technical field
The invention belongs to building construction measurement technical field, in particular to a kind of brill suitable for soft soil foundation Man-Hole digging Tool.
Background technique
Coastal and beach or blowing filling soft soil foundation processing along the river is all at home and abroad common engineering project, this kind of weak soil work Cheng Xingzhi is poor, water content is high, void ratio is high, and processing difficulty is big, thus monitoring during processing is just essential, example Such as, the water table measure in treatment process, monitoring pore water pressure, settlement monitoring, deeply mixing cement-soil pile monitoring etc..It is related to Monitoring facilities have water level pipe, pore pressure gauge, deeply mixing cement-soil pile inclinometer pipe etc..
Currently, substantially there was only a kind of form for the inbuilt method of above-mentioned monitoring facilities, be using drilling machine pore-forming or It is pressed into using drilling machine.Using geological drilling rig pore-forming, hole is filled after being then embedded to monitoring facilities.Such method drawback is It is embedded every time to require drilling machine and march into the arena, if the embedded points of single are few, transfer drilling machine and professional machine hand, support staff are marched into the arena cost It is higher, it is complicated for operation, it is affected by place Superficial Geologic Condition, drilling machine can not carry out operation when surface layer soil property is softer, and If stratum is softer or contains sand, it is easy collapse hole, buries difficulty after causing pore-forming.
Summary of the invention
The present invention is to solve technical problem present in well-known technique and provide a kind of suitable for soft soil foundation Man-Hole digging Drilling tool, monitoring facilities can reduce using the drilling tool and bury cost, and influenced by place Unfavorable geology condition smaller.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that a kind of be suitable for weak soil The drilling tool of ground Man-Hole digging, including a sequentially connected drill bit, a drill bit connecting tube, at least one spreading from bottom to up Pipe and a push pipe;The drill bit includes tubular body, and drill bit helical blade is provided with around drill bit tubular body, in institute The lower end for stating drill bit tubular body is connected with conical hollow point, is equipped with ear shaped spiral in the upper end of the drill bit tubular body and opens Mouthful;The drill bit connecting tube includes tubular body, and drill bit connecting tube helical-blade is equipped with around drill bit connecting tube tubular body Piece is connected with necking down pipe in the lower end of the drill bit connecting tube tubular body, on the outside of the necking down pipe of drill bit connecting tube be equipped with The stud I of the ear shaped spiral opening occlusion is equipped with the opening of falling T-shaped I in the upper end of the drill bit connecting tube tubular body;It is described The lower end of extension spray lance is equipped with necking down pipe, and the stud II being engaged with the opening of falling T-shaped I is equipped on the outside of the necking down pipe of extension spray lance, The upper end of the extension spray lance is equipped with the opening of falling T-shaped II;When the extension spray lance includes at least two, described in neighbouring two Extension spray lance is connected by corresponding stud II with the opening of falling T-shaped II;The lower end of the push pipe is equipped with necking down pipe, in push pipe It is equipped with the stud III being engaged with the opening of falling T-shaped II on the outside of necking down pipe, is equipped in the upper end of the push pipe perpendicular affixed Casing.
The advantages and positive effects of the present invention are: only need 2 people that can screw in drill bit and drilling pipe in soil, pore-forming speed Degree is fast, and it is short to bury the time, using hollow drilling pipe will inbuilt monitoring pipe or sensor strip bury middle designated depth, positioning standard Really, bury high-efficient, operating cost is low, and is not influenced substantially by place Unfavorable geology condition, without additional after monitoring facilities are embedded Stress is conducive to protect monitoring facilities.In conclusion easy to use, maneuverability of the invention, buries accuracy height, It is not influenced by collapse hole, the embedded cost of monitoring facilities can be substantially reduced, improve the inbuilt controllability of monitoring facilities.And structure Simply, low in cost.
