Civil engineering safety construction sand box device

Abstract

The invention discloses a civil engineering safety construction sand box device, and belongs to the technical field of civil engineering. The civil engineering safety construction sand box device comprises a sand box body, the inner bottom of the sand box body is slidably connected with a bottom plate, the bottom of the bottom plate is connected with the bottom of the sand box body through springs, the bottom of the bottom plate is fixedly connected with a vibration exciter, and the inner side wall of the sand box body is slidably connected with a lower pressing plate. According to the sand box device, a driving motor is installed at the end, away from the sand box body, of a fixing cylinder a, when the amount of gravel in the sand box body is large or the gravel needs to be discharged out of the sand box body, an electric hydraulic telescopic rod drives a fixing plate to move in the direction of the sand box body, meanwhile the driving motor drives an auger to be rotationally inserted into the sand box body, sand and stone in the sand box body are discharged, normal use of the sand box device is not affected, the connecting cylinder can be detached from the fixing cylinder a and installed on other sand box bodies to be used after pouring is completed, resource waste is avoided, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, and more specifically relates to a sand box device for safe construction of civil engineering. Background technique [0002] The sand box is used in the construction of steel pipe pile support cast-in-place beams for unloading purposes. When the steel pipe pile support Bailey beam is erected, the construction of the cast-in-place beam will start. After the cast-in-place beam construction is completed, the support needs to be removed. At this time, it is difficult to remove the support, because the weight of the beam body is all pressed on the support. It is not an easy task, which requires us to set up a sand box between the steel pipe pile and the distribution beam in advance when making the support, and the sand box acts as a jack. The existing sand box needs to be screened to a standard sand size before filling with sand and gravel, which is cumbersome to operate, and it is difficul...

AI Technical Summary

Problems solved by technology

The existing sand box needs to be screened to the size of standard sand before filling with sand and gravel, which is troublesome to operate and difficult to control the amount of filled sand and gravel. When dismantling, the sand and gravel are directly discharged, which wastes resources and increases costs.
