AI Technical Summary

Technical Problem

Traditional cave warehouses suffer from problems such as water seepage through rock fissures, uneven distribution of lateral pressure on grain, poor thermal insulation, and long construction periods, and their structures are prone to cracking.

Method used

The cave-like structure is composed of a steel arch combining beams and columns, anchored steel pipes, embedded parts along the column base, horizontal steel beams, vertical steel beams, and waterproof and pressure-bearing insulation boards. It is connected by welding and concrete filling to form a stable load-bearing system, and the cavity is connected to the water collection and drainage ditch to achieve integrated waterproof and pressure-bearing.

Benefits of technology

It achieves a stable load-bearing structure, optimizes stress distribution, resists lateral pressure on grain, provides thermal insulation, improves warehouse utilization, and effectively removes moisture from the cavity, ensuring grain safety.

Abstract

The utility model belongs to the technical field of grain storage buildings, and particularly relates to a cave warehouse integrated structure with bearing and waterproof functions. The cave bin integrated structure with the bearing and waterproof functions comprises a beam-column-integrated steel arch, a pulling and anchoring steel pipe, a column bottom full-length embedded part, a horizontal steel beam, a vertical steel beam, a waterproof pressure-bearing heat preservation plate and a water collection and drainage ditch, and the beam-column-integrated steel arch, the pulling and anchoring steel pipe, the column bottom full-length embedded part, the horizontal steel beam and the vertical steel beam form a bearing structure. Waterproof pressure-bearing insulation boards are hung outside the horizontal steel beams and the vertical steel beams to resist water and bear pressure, the cavity is located between the supporting finished face and the waterproof pressure-bearing insulation boards and connected with the water collecting and draining ditch, and the supporting finished face is connected with the water collecting and draining ditch on the ground. According to the utility model, the bearing system is more stable, the stress distribution is optimized, and the integration of water resistance, pressure bearing and heat preservation can be realized.
