Description
Technical field
The present invention relates to a kind of spanner for mounting and dismounting catheter interface, is a kind of sickle spanner for being used to fastening and dismantling bored pile guide interface specifically.
Background technology
In recent years, with the rapid development of China's economy, skyscraper, municipal bridge project under construction are on the increase, filling pile construction has that bearing capacity ability is high, easy for construction, without friction during construction, without land upheaval or sidesway, surrounding building is endangered small, use range is big, is all kinds of China Democratic National Construction Associations, the important component of municipal construction the advantages that suitable for various geological conditions.Bored pile construction engineering method flow：Slurrying → stake position setting-out → embedded casing → rig positioning → drilling and forming hole → borehole cleaning simultaneously checks hole quality → decentralization steel reinforcement cage → decentralization conduit → pouring underwater concrete, and → extracting conduit and casing stage by stage → checks on the quality.Cast-in-situ bored pile can efficiently reduce the contact surface of concrete and mud by steel conduit concrete perfusion, so as to effectively solve the problems such as inadequate bearing capacity after cast-in-situ bored pile pile, slag inclusion, broken pile.Catheter diameter is generally 200-300mm, and conduit standard knot length is preferably 2.5-3m, and first segment bottom tube length is no less than 4m, preferably adds " 〇 " type rubber ring to connect with steel spiral screw thread between each conduit, ensure good sealing property, prevents that mud is penetrated into pipe.
At present, cast-in-situ bored pile catheter interface fastens and the main method of dismounting is using manual operations, but there are many drawbacks in this kind of method, first, fasten loosely, it is not enough to fasten conduit completely using the stiction between circular steel catheter interface and hand, the outer mud of pipe is easily infiltrated into pipe, influences pile quality；Second, after perfusion, after conduit is extracted from concrete, interface may penetrate into cement mortar, the difficulty of increase dismounting conduit.
Therefore known cast-in-situ bored pile catheter interface fastening and dismounting mode there are problems that above-mentioned a variety of inconvenience and.
The content of the invention
The purpose of the present invention, it is to propose a kind of sickle spanner for being used to fastening and dismantling bored pile guide interface.
To achieve the above object, technical solution of the invention is：
A kind of sickle spanner for being used to fastening and dismantling bored pile guide interface, including arched arm and handle, it is characterised in that：
The arched arm is cut into by steel plate, and the internal diameter radian of arched arm is consistent with the connector external diameter radian at catheter interface with bored concrete pile hopper, and arc length is the 1/3 of connector circumferential length, and the both ends of arched arm set directed arc internal projection；
One end of the handle and one end of arched arm are welded admittedly, handle length 20-40cm；
It is described.
The sickle spanner for being used to fasten and dismantle bored pile guide interface of the present invention can also be further achieved by the following technical measures.
Foregoing method the, wherein steel plate thickness >=2mm.
Foregoing method, wherein the raised bossing length >=5mm.
Foregoing method, wherein the material of the handle is diameter ＞ 25mm reinforcing bars.
Foregoing method, wherein the reinforcing bar of the handle is spiral.
Foregoing method, wherein the arched arm and handle of the sickle spanner cut in same steel plate be made together.
After adopting the above technical scheme, the present invention's has advantages below for the sickle spanner that fastens and dismantle bored pile guide interface：
1st, sickle spanner is simple in construction, easy to make；
2nd, it is easy to use, it is time saving and energy saving, simplify work；
3rd, gather materials on the spot, it is cheap.
