The utility model discloses a kind of rapid pouring mould of assembly integral type two-way dense rib composite floor slab prefabricated concrete bottom plate, including bottom plate, first intermediate plate, second intermediate plate, first side edge plate, second side edge plate and third side edge plate.The pouring mould in the utility model has fast pouring speed, is easy to vibrate, easy to demould, can greatly reduce construction error and construction difficulty, while improving pouring efficiency, realize the promotion of assembly building efficiency.

The utility model relates to expansion joint glue injection device technical field, concretely is a kind of high-pressure glue injection device for elastomer expansion joint material.The device includes base, high-pressure injection cylinder being set on base, filling mechanism for conveying glue to high-pressure injection cylinder, piston is slidably arranged on the inner side wall of high-pressure injection cylinder, driving mechanism for driving the linear sliding of high-pressure injection cylinder is set on the base;High-pressure injection cylinder is connected with the tail end of conveying long tube, and the first valve is set in the head end of conveying long tube.The characteristics of the device are that by pushing piston, great pressure is applied to the glue in high-pressure injection cylinder, so that the glue overcomes its own gravity and viscosity, and is injected into the use position after climbing a large difference.The device has simple structure, can quickly realize the purpose of pouring elastomer material directly from under bridge to bridge joint, and meets construction demand.

The utility model relates to the technical field of tunnel construction, in particular to a tunnel groove formwork trolley which comprises a trolley body capable of moving in a tunnel, the two sides of the trolley body are each provided with a walking mechanism, a positioning mechanism, a formwork supporting mechanism, a concrete pouring chute mechanism and a demolding mechanism, the structure is reliable, operation is convenient, the pouring speed is high, and the working efficiency is high. The whole construction cost is low, the functions of automatic walking, automatic formwork erecting, automatic demolding and the like are achieved, the labor intensity is greatly reduced, the requirement for constructors is reduced, in addition, the trolley is provided with the walking mechanism, a formwork can be easily moved to the next pouring section through the walking system after demolding, and operation is extremely convenient and fast. Compared with a traditional split mounting type formwork, the ditch cable trough trolley can achieve double-side synchronous construction, and three sections of formworks are alternately used. And the construction efficiency is obviously improved. And the hydraulic system controls the lifting and transverse movement of the template, so that the positioning is simple and accurate.
