Workshop pit and construction method thereof

Abstract

The invention relates to a workshop pit and a construction method thereof. The workshop pit comprises a supporting layer composed of multiple layers of supporting rods, exhaust pipes arranged on the periphery of the supporting layer, an exhaust supporting plate arranged on the top of the supporting layer, exhaust passages connecting the exhaust supporting plate with the ground and a cast-cured layer. The outer wall of the cast-cured layer is provided with a facing sand layer. The construction method of the workshop pit comprises the steps of laying the supporting layer in the pit, arranging the exhaust pipes, laying the exhaust supporting plate, pouring castables and additionally the facing sand layer. Through the arrangement of the steel part supporting layer, the problem of gravel pouring instability can be effectively avoided. Meanwhile, the exhaust pipes are arranged on the periphery of the supporting layer, and the exhaust supporting plate and an air draft humidity exhaust fan are arranged on a supporting frame, and the exhaust effect of a whole hard sand bed can be effectively improved. According to the workshop pit, the layered poured cast-cured layer is laid on the exhaust supporting plate, and reinforcing rib plates are evenly distributed, so that the castables are kept clean and are free of contamination, and the pressure resistance of the cast-cured layer is also enhanced.

Description

technical field [0001] The invention relates to a building structure, in particular to a workshop pit and a construction method thereof. Background technique [0002] Most of the workshop production is based on the ground shape, which takes up a lot of space. There are many tooling and auxiliary accessories, the safety factor is small, and it is not environmentally friendly and energy-saving, which has a great impact on the product quality of the castings. Therefore, pit design began to be slowly promoted. In common pit design, generally only reinforced concrete is used to cast the bottom plate of the pit and the surrounding wall panels. This structure generally has no problem for shallow pits. However, for deeper pits, because the lateral soil pressure on the wall panels of the pits is relatively large, it is easy to squeeze the wall panels of the pits. In order to strengthen the anti-extrusion ability of the surrounding wall panels, buttress columns are usually arranged ...

AI Technical Summary

Problems solved by technology

In this way, not only will a lot of materials be used, but also the design and calculation are cumbersome, the construction is difficult, and the construction period is long.

Moreover, there are many damp problems in the pits, and long-term use is prone to water accumulation
