Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of simple in structure, can simple and efficient construction and the jacking construction cordwood steel structure open caisson of good seal performance.
The utility model solves its technical problem and takes following technological scheme to realize:
This jacking construction cordwood steel structure open caisson, housing structure for steel structure casing, back back iron, push-bench inlet formation, it is characterized in that: four walls of open caisson are steel structure casing and by the mutual affixed modular construction that constitutes of screw pre-buried on it, bottom surface at these four walls all is fixed with a basil framework by pre-sunk screw, is perfused with a reinforced concrete substrate between this basil framework.
And, between basil framework and the steel structure casing, between the steel structure casing waterproof sealing gasket is installed all.
And, the uniform pulp-water through hole that is shaped on the steel structure casing that constitutes four walls.
And, vertically be embedded with the two rows pre-sunk screw affixed on the basil framework with the steel structure casing.
The utility model compared with prior art has significant advantage and beneficial effect, is in particular in:
This steel structure open caisson can be risked the figure of plurality of specifications model (as length; width; the degree of depth; inlet diameter) satisfies the needs of our municipal engineering push pipe; and can repeatedly use repeatedly; assembly unit saves time; simple to operate; Security raising greatly for push pipe; also played protective action for the electric equipment in the hole; reduced working strength of workers; can accomplish clean and tidy clean in the foundation ditch; after finishing, jacking construction can not produce the cavity, ground; there is not hidden danger in pavement construction in the future yet; and in the hole, do not have flowing water and stream mud phenomenon; ground building has also been played protective action, can reduce construction cost greatly, increased work efficiency; save a large amount of timber.
