Description
Technical field
This utility model relates to a kind of spanner mounting and dismounting catheter interface, specifically, be a kind of for fastening and
The sickle spanner of dismounting bored pile guide interface.
Background technology
In recent years, along with developing rapidly of China's economy, skyscraper, municipal administration bridge project under construction are on the increase, perfusion
It is high that pile driving construction has bearing capacity ability, easy construction, friction during construction, without land upheaval or sidesway, to surrounding building danger
Evil is little, and range is big, it is adaptable to the advantages such as various geological conditions, is the important component part of all kinds of China Democratic National Construction Association, municipal construction.Bore
Hole pouring pile construction flow process: slurrying → stake position setting-out → bury casing → rig location → drilling and forming hole → clear hole underground also
Check hole quality → transfer steel reinforcement cage → transfer conduit → pouring underwater concrete → extract conduit and casing → inspection stage by stage
Look into quality.Cast-in-situ bored pile can efficiently reduce the contact surface of concrete and mud by steel conduit concrete perfusion, thus has
Effect solve after cast-in-situ bored pile pile bearing capacity not, the problem such as slag inclusion, broken pile.Catheter diameter is generally 200-300mm,
Conduit standard knot length is preferably 2.5-3m, and length of tube at the bottom of first segment is no less than 4m, preferably adds with steel spiral screw thread between each conduit
" " type rubber ring connects, it is ensured that good sealing property, is strictly on guard against that mud penetrates in pipe.
At present, the main method of the fastening of cast-in-situ bored pile catheter interface and dismounting is to use manual operations, but this kind of method
There is a lot of drawback, one is to fasten loosely, utilizes the stiction between circular steel catheter interface and hands to be not enough to completely and fastens
Conduit, manages outer mud and easily infiltrates in pipe, affect pile quality；After two are perfusion, after conduit is extracted from concrete, connect
At Kou, possible water leaking-in mud, increases the difficulty of dismounting conduit.
The fastening of the most known cast-in-situ bored pile catheter interface and dismounting mode also exist above-mentioned all inconvenience and problem.
Utility model content
The purpose of this utility model, is that proposing a kind of sickle type for fastening and dismantle bored pile guide interface pulls
Hands.
For achieving the above object, technical solution of the present utility model is:
A kind of sickle spanner for fastening and dismantle bored pile guide interface, including arched arm and handle, its feature
It is:
Described arched arm is cut into by steel plate, the company at the internal diameter radian of arched arm and bored concrete pile hopper and catheter interface
Connecing device external diameter radian consistent, arc length is the 1/3 of adapter circumferential length, and the two ends of arched arm set directed arc internal projection；
One end of described handle is welded admittedly with one end of arched arm, handle length 20-40cm；
Described.
Sickle spanner for fastening and dismantle bored pile guide interface of the present utility model can also use following
Technical measures realize further.
Aforesaid method, wherein said steel plate thickness >=2mm.
Aforesaid method, the bossing length >=5mm of wherein said projection.
Aforesaid method, the material of wherein said handle is diameter ＞ 25mm reinforcing bar.
Aforesaid method, the reinforcing bar of wherein said handle is spiral.
Aforesaid method, the arched arm of wherein said sickle spanner cuts at same steel plate together with handle and makes.
After using technique scheme, the sickle type for fastening and dismantle bored pile guide interface of the present utility model is pulled
Hands has the advantage that
1, sickle spanner simple in construction, easy to make；
2, easy to use, time saving and energy saving, simplify work；
3, gather materials on the spot, cheap.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, this utility model is illustrated further.
Embodiment 1
Sickle spanner for fastening and dismantle bored pile guide interface of the present utility model, including arched arm 1 and handle
Hands 2.
Referring now to the structural representation that Fig. 1, Fig. 1 are this utility model embodiment sickle spanner.As it can be seen, it is described
Arched arm 1 is cut into by thickness 2mm steel plate, the adapter at the internal diameter radian of arched arm and bored concrete pile hopper and catheter interface
4 external diameter radians are consistent, and arc length is the 1/3 of adapter circumferential length, and the two ends of arched arm set the projection 3 in directed arc；
One end of described handle 2 is welded admittedly with one end of arched arm 1, handle length 35cm.The material of described handle 2 is diameter
30mm spiral.
Embodiment 2
In the present embodiment, the arched arm 1 of sickle spanner cuts at same steel plate together with handle 2 and makes, and uses thickness 3cm
Steel plate cuts out sickleshaped according to hopper bore electric welding and makes arched arm and the integral spanner of handle.
