Description

The horizontally-spliced structure of coercion underground continuous wall
Technical field
The utility model is related to a kind of horizontally-spliced structure of coercion underground continuous wall, especially suitable for coercion underground continuous wall Horizontal splicing during as foundation pit enclosure and outer wall of basement.
Background technology
At present, for coercion underground continuous wall based on cast in situs, the utilization of coercion underground continuous wall is considerably less.This is because Conventional coercion underground continuous wall length direction does not set seam, leads to that monolithic coercion underground continuous wall length is long, and weight is much, no Transport and lifting is suitble to also result in that coercion underground continuous wall excavation of foundation pit depth applicatory is very shallow, and application range extremely has Limit, economical very poor, this all greatlys restrict the application of Precast Diaphragm Wall.
Therefore, it is simple in structure how to provide one kind, it is easy for construction, it reliably can effectively transmit the adjacent prefabricated underground of two panels and connect The internal force of continuous wall, separately achievable coercion underground continuous wall do not do remaining processing can be used directly as outer wall of basement it is prefabricated The horizontally-spliced structure of diaphram wall and its construction method, it has also become underground construction circle needs the technology of further improvement and optimization to ask Topic.
Utility model content
It is simple in structure the purpose of this utility model is to provide a kind of horizontally-spliced structure of coercion underground continuous wall, construction It is convenient, the internal force of adjacent two panels coercion underground continuous wall reliably can be effectively transmitted, realizes that coercion underground continuous wall does not do remaining Processing can be used directly as outer wall of basement.
The technical solution adopted in the utility model is as follows:
A kind of horizontally-spliced structure of coercion underground continuous wall, is formed by several wallboards are horizontally-spliced, which is characterized in that pre- The both ends of wallboard A and prefabricated panel B processed are respectively equipped with elongated wedge shaped side concave volume and trapezoidal side convex body, are buried in the convex body of side If connecting reinforcing bar, the notch that reinforcing bar matches and up and down elongated, phase are connect in the setting of wedge shaped side concave volume bottom and side convex body Adjacent two panels prefabricated panel A and prefabricated panel B is connected by side convex body with side concave volume, and the gap that inside is formed is triangle Injected hole injects rubber concrete to the notch cavity in wedge shaped side concave volume by triangle injected hole and fills, side concave volume Rubber shock-absorbing pad is equipped with side convex body contact portion.
Further, the upper and lower ends of the prefabricated panel A and prefabricated panel B are respectively equipped with top concave volume and lower part is convex Body, quantity can correspond to equidistantly distributed according to the factor designs such as engineering construction, top concave volume and lower part convex body.
Further, the side convex body cross section of the prefabricated panel A and prefabricated panel B is in isosceles trapezoid, and side is recessed Body cross section is in isosceles triangle, and the cross section of top concave volume and lower part convex body is all arc.
Further, it is all covered with rubber shock-absorbing layer inside the top concave volume of the prefabricated panel A and prefabricated panel B Lid, is equipped with Rubber shock-absorbing pad in two slope surfaces of the side convex body respectively, and the Rubber shock-absorbing pad is along described prefabricated The short transverse overall length arrangement of lower diaphragm wall.
Further, the construction method of the horizontally-spliced structure of a kind of coercion underground continuous wall, includes the following steps:First Step, by coercion underground continuous wall lateral arrangement on same plane, the side concave volume of a piece of coercion underground continuous wall with it is adjacent pre- Diaphram wall side processed convex body is corresponding;Second step by injected hole toward notch slip casting, is formed in upper and lower corresponding notch Chamber in casting concrete so that lateral coercion underground continuous wall closely connects;Third walks, and two layers of prefabricated underground of lifting are continuous Wall slowly falls in the top of one layer of coercion underground continuous wall, connects its two layers of prefabricated underground under the action of dead weight The lower part convex body of continuous wall and the top concave volume automatic attaching of one layer of coercion underground continuous wall, precise positioning complete installation.
The beneficial effects of the utility model:
The beneficial effects of the utility model are provided separately due to coercion underground continuous wall, reduce monolithic prefabricatedly The length and weight of lower diaphragm wall are suitble to transport and lifting;
Since the size of spliced coercion underground continuous wall entirety can dramatically increase, increase prefabricated underground and connect Continuous wall excavation of foundation pit depth applicatory makes it possible to be applied to use compared in existing deeper foundation pit, has good warp Ji effect;
Since the cross section of the convex body is trapezoidal, not only so that the docking of adjacent two panels coercion underground continuous wall is more square Just, the installation effectiveness effectively improved;
Splicing up and down two panels coercion underground continuous wall when, above a piece of coercion underground continuous wall can conduct oneself with dignity Under the action of along the convex body slope surface automatic attaching precise positioning, it is ensured that installation accuracy.
