A kind of drill device with arc joint

Abstract

A drill bit device with an arc-shaped connector comprises a plurality of steel strips arranged on the surface of a drill bit. At least one arc-shaped plate head is connected to the drill bit through the steel strips. The drill bit device is suitable for connector-pipe method type diaphragm wall connector construction, and has the multiple advantages of being easy to manufacture, convenient to install, capable of being repeatedly utilized, and the like.

Description

technical field [0001] The invention relates to a drill bit device with an arc-shaped joint, which is especially suitable for solving the construction of an anti-seepage wall, and can prevent joint pipes from being buried and stuck. Background technique [0002] In recent years, the construction technology of concrete cut-off walls has advanced by leaps and bounds. The inter-section joints of concrete cut-off walls are no longer limited to the early socket method. been widely applied. [0003] Although the joint pipe method has the incomparable advantages of other joint connection technologies: it saves the time for laying joint concrete, improves the efficacy, saves wall materials, and reduces costs, etc. Defects, concrete breakage in the guide groove, failure of the pipe puller, improper control of the initial setting time, deflection of the joint pipe and other factors lead to the failure of the joint pipe to be pulled out, and the phenomenon that the joint pipe is cast ...

Problems solved by technology

[0003] Although the joint pipe method has the incomparable advantages of other joint connection technologies: it saves the time for laying joint concrete, improves the efficacy, saves wall materials, and reduces costs, etc. Defects, concrete breakage in the guide groove, failure of the pipe puller, improper control of the initial setting time, deflection of the joint pipe, etc., lead to the failure of the joint pipe to be pulled out, and the phenomenon that the joint pipe is cast in the concrete joint hole often occurs

Because the joint pipe does not have the anti-seepage function, and it cannot be made into a solid continuous body with the underground diaphragm wall, the remedial project is costly and difficult, and the traditional solution will seriously affect the quality of the anti-seepage wall
