Abstract
The utility model relates to an underground continuous wall, and particularly relates to a locking notch pipe for an underground continuous wall. The crescent key connected locking notch pipe for an underground continuous wall is characterized in that, the locking notch pipe is divided into many sections, one end of each section is a protruding head and the other end is a concave head, the head and the tail of two sections of the locking notch pipe are connected via the protruding head and the concave head, the protruding head and the concave head are in a keyed joint, and are fixed by a bolt. The crescent key connected locking notch pipe for an underground continuous wall in the utility model solves the problem of influence upon construction period and construction cost due to difficult assembling and disassembling of locking notch pipe in underground continuous wall construction.
Description
Technical field
The utility model relates to diaphragm wall, relates in particular to a kind of diaphragm wall fore shaft pipe.
Background technology
In the diaphragm wall engineering construction, fore shaft pipe size is big, and weight is big, and the workman carries painstakingly, and dismounting is difficulty very, and this is with regard to directly having influenced normally carrying out of construction, to such an extent as to construction period and construction cost all can have bigger increase.
Summary of the invention
The utility model is intended to address the above problem, and a kind of diaphragm wall Woodruff key jointing type fore shaft pipe is provided.The utility model has solved fore shaft pipe installation in the construction of diaphragm wall, dismounting difficulty, influences construction period and construction cost.
The utility model is achieved in that a kind of diaphragm wall Woodruff key coupling type fore shaft pipe, described fore shaft pipe is divided at least two sections, wherein an end of every section is that plush copper one end is recessed head, two-phase lock mouth tube head tail links together by plush copper and recessed head, be connected to together between plush copper and the recessed head, and by bolt.
Described diaphragm wall Woodruff key jointing type fore shaft pipe, described key comprises three Woodruff keys of equal portion on the periphery of recessed head end, and the periphery of described plush copper end is provided with corresponding keyhole, and described bolt is screwed into Woodruff key by this keyhole and fixes.
The utility model is divided into some joints with the fore shaft pipe, link by concavo-convex head between every adjacent standard knot (6m, 4m) fore shaft pipe two welding fore shaft pipe and the fore shaft pipe, connect by three selenodont keys and three M12 screws between the concavo-convex head, the utility model has reduced fore shaft pipe weight, carries, installs and removes all very convenient; By facts have proved, the dismounting of diaphragm wall fore shaft pipe Woodruff key interconnection system fore shaft pipe construction method is all very convenient
