Abstract
A kind of long-spiral drilling machine soil sampler, it includes oil cylinder and oil cylinder pull bar, the casing that fetches earth, clamshell gate, hole pin, cylinder lever connecting rod etc..It is characterized in that top oil cylinder for hydraulic oil pump and soil sampler attachment means and provides power for soil sampler device, soil sample barrel provides space for soil sampler other devices and accommodates the soil body, connecting plate is connected by oil cylinder pull bar with oil cylinder, in connecting plate both sides, reserving hole sets steady brace, pull bar connects top connecting plate and bottom clamshell gate and provides intermal force, clamshell gate is connected with pull bar, the soil body can be made to be fixed in soil sampler after closure.The particularly suitable long screw auger drilling deposited pile stake top that is applied to of the present invention is to the condition of construction for having emptying aperture to ground, it is therefore prevented that the residual soil body enters concrete pile body, is effectively guaranteed pile quality.
Description
Technical field
The present invention relates to a kind of new technique device fetched earth, more particularly to a kind of rig soil sampler, it is adaptable to long spire
There is the construction environment of emptying aperture on cast-in-situ bored pile stake top to ground.
Background technology
Long screw auger drilling deposited pile technique is not limited by level of ground water due to its Superfluid state concrete pumped in pile foundation,
Coefficient of friction is low, aggregate good dispersion, the characteristics of being not likely to produce isolation, and its machine of pore-forming one once completes, operates letter in addition
Just；Low noise, without friction, construction cost relative moderate compared with other construction methods.Ten are classified as by the Ministry of Construction within 2005 to push away greatly
One of wide technology.It is developed so far, long screw auger drilling deposited pile technique is widely applied in pile foundation engineering, however as applying
Work demand is continually changing, and many areas need to carry out emptying aperture construction (the non-natural ground of stake top) using long auger technique.And
There is following drawback in this construction method, during descending reinforcing cage, and the empty part residual soil body that bores can be made to enter concrete pile body, pile body is caused
Quality is reduced.
The content of the invention
Can be emptying aperture part satholith by ground to the stake top part soil body it is an object of the invention to provide a kind of device
Body takes down, so as to avoid this part soil body during descending reinforcing cage from entering in the concrete irrigated, so as to influence pile quality.
The purpose of the present invention realized by following device, long-spiral drilling machine soil sampler, for long-spiral drilling machine to be applied
The empty part residual soil body that bores of work takes down, including oil cylinder and oil cylinder pull bar, the casing that fetches earth, connecting hole pin, movable clamshell gate, and it is special
Levy and be：Top hydraulic oil pump is connected with soil sampler by top oil cylinder；Oil cylinder pull bar passes through the method for being fixed on and fetching earth on casing
Blue plate hole is connected with connecting plate, and the vertical pull bar at middle part connects the company being connected with oil cylinder pull bar respectively by upper and lower ends aperture pin
Fishplate bar, clamshell gate；Bottom clamshell gate is connected with the casing that fetches earth by macropore pin, is vertical pull bar, connecting plate inside the casing that fetches earth
Deng providing space and accommodate the soil body；The closure of clamshell gate is controlled by vertical pull bar；Lower end sets clamshell gate, grab bucket folding seam two
Side is set and connecting plate identical aperture pin, is connected with vertical pull bar；Clamshell gate both sides set macropore pin, for the casing that fetches earth
It is connected, control grab bucket folding, the flanged plate is 400~500mm of diameter circular flange plate；The long 200mm of connecting plate, it is wide
200mm, high 20mm；On the lower side in the middle part of the connecting plate to set two aperture pins being connected with vertical pull bar, connecting plate is drawn with oil cylinder
Bar uses embedded connection.
As preferred scheme, top oil cylinder is hydraulic oil pump and soil sampler attachment means, 100~150mm of diameter,
Oil pump provides power for soil sampler.
As preferred scheme, diameter 80mm, long 200mm oil cylinder pull bar are vertically connected with oil cylinder and connecting plate.
It is the vertical pull bar of strip as preferred scheme, in the middle part of soil sampler, upper end passes through connecting plate and oil cylinder pull bar
Connection, lower end is connected with clamshell gate, collectively forms the load transfer device of soil sampler.
As preferred scheme, lower end sets clamshell gate, and grab bucket folding seam both sides are set and connecting plate identical aperture pin,
It is connected with vertical pull bar；Clamshell gate both sides set macropore pin, for being connected with the casing that fetches earth, and control grab bucket folding, is soil sampler
Drawing out soil equipment.
After the completion of long auger and concrete perfusion, whole soil sampler device is put into hole, reached after specified altitude assignment,
Power is provided by hydraulic oil pump, intermal force is played by oil cylinder and the connecting plate for being fixed on oil cylinder pull bar, then pass through pull bar control
Clamshell gate closure processed, bores the part residual soil body by top sky and is mounted in soil sampler, lift soil sampler, and the soil body in soil sampler is fallen
Go out.
The present invention can empty empty part of boring and remain the soil body, it is to avoid this portion after the completion of long auger and concrete perfusion
Divide the soil body to be fallen into steel reinforcement cage decentralization process in concrete, influence pile quality.
