A kind of sand box device for safe construction of civil engineering

Abstract

The invention discloses a sand box device for civil engineering safety construction, which belongs to the technical field of civil engineering and comprises a sand box body. The inner bottom of the sand box body is slidably connected with a bottom plate, and the bottom of the bottom plate is connected to the sand box body through a spring. The bottom is connected, the bottom of the bottom plate is fixedly connected with a vibrator, and the inner side wall of the sand box body is slidably connected with a lower pressure plate. In the present invention, by installing a drive motor on the end of the fixed cylinder a away from the sand box body, when the amount of sand and gravel inside the sand box body is large or the sand and gravel need to be discharged from the sand box body, the electro-hydraulic telescopic rod drives the fixed plate to The direction of the sand box body moves, and at the same time, the drive motor drives the auger to rotate and insert it into the inside of the sand box body to discharge the sand inside the sand box body without affecting the normal use of the sand box device. The cylinder is removed from the fixed cylinder a and installed on other sand box bodies for use, which avoids waste of resources and saves costs.

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.
