Assembly type prefabricated square culvert forming device and assembly type prefabricated square culvert forming and manufacturing process

Abstract

The invention discloses an assembly type prefabricated square culvert forming device and an assembly type prefabricated square culvert forming and manufacturing process. The assembly type prefabricated square culvert forming device comprises a base; a plurality of vibration devices are arranged at the bottom of the interior of the base; each vibration device comprises a first motor base; the bottom of each first motor base is fixedly connected with the inner bottom of the base; a first motor is arranged in the center of the top of each first motor base; a first motor shaft is arranged at the output end of the side face of the first motor; a runner is arranged on the side, away from the first motor, of the first motor shaft; a connecting rod is arranged on the outer surface of the other side of the runner; a plurality of sleeves penetrating through the top of the base are arranged at the top of the interior of the base; and bearing columns are arranged in the sleeves. The assembly typeprefabricated square culvert forming device has the beneficial effects that when the first motor drives a supporting plate to ascend and descend in a reciprocating mode, impact force generated by descending of the supporting plate can be absorbed by a plurality of buffer springs, meanwhile, a plurality of limiting columns play a role in limiting the lowest descending height of the supporting plate, and the overall stability of the forming device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of square culvert processing devices, in particular, to an assembled prefabricated square culvert forming device and a manufacturing process thereof. Background technique [0002] The prefabricated square culvert is a kind of box-type pipe culvert prefabricated in the factory by using high-strength reinforced concrete, which is hoisted and connected at the construction site. The box culvert can be widely used in power tunnels and urban integrated pipe corridors, commonly known as precast concrete square pipe culverts. [0003] The existing prefabricated square culvert forming device does not have the function of vibration compaction in the process of concrete pouring, resulting in a low filling rate of concrete in the mold cavity, poor concrete compaction effect, and low strength of the final formed square culvert. The lifespan is short, and there is no auxiliary demolding device during the demoulding proce...

AI Technical Summary

Problems solved by technology

[0003] The existing prefabricated square culvert forming device does not have the function of vibration compaction during the concrete pouring process, resulting in low concrete filling rate in the mold cavity, poor concrete compaction effect, and low strength of the final formed square culvert. The service life is short, and there is no auxiliary demoulding device in the process of demoulding the square culvert, so that the adhesion between the square culvert and the inner wall of the cavity eventually leads to the low integrity of the square culvert, a large number of damages, and it is not beautiful enough, and The existing square culvert forming device has a complex structure, and it takes a lot of operating time to make square culverts each time, which wastes a lot of manpower and material resources
