Sand cushion isolation and shock absorption device for comprehensive pipe gallery and building method thereof

Abstract

The invention provides a sand cushion isolation and shock absorption device for a comprehensive pipe gallery and a building method thereof. The sand cushion isolation and shock absorption device has the advantages of simple structure, convenience in construction, low cost of construction, high applicability and convenience in popularization and implementation. The sand cushion isolation and shock absorption device comprises a foundation isolation and shock absorption device and side wall isolation and shock absorption devices. The comprehensive pipe gallery is buried in a stratum and is formed by foundation mats at the bottom, side walls on the two sides and top plates at the top in a surrounded mode. A foundation isolation and shock absorption layer is arranged under the foundation mats of the comprehensive pipe gallery and is formed by packing coarse sand by earthwork cloth, and a rammed 37 lime earth layer is arranged under the foundation isolation and shock absorption layer. Side wall isolation and shock absorption layers are arranged on the earth meeting surfaces of the side walls of the comprehensive pipe gallery and are formed by packing coarse sand by earthwork cloth. The foundation isolation and shock absorption device and the side wall isolation and shock absorption devices surround the three surfaces of the comprehensive pipe gallery except for the top plates, thereby forming an isolation and shock absorption layer.

Description

technical field [0001] The invention relates to the technical field of shock-isolation and shock-absorbing construction of a comprehensive pipe gallery, in particular to a sand-cushion shock-isolation and shock-absorbing device for a comprehensive pipe gallery and a construction method thereof. Background technique [0002] The seismic isolation and energy dissipation of existing buildings is basically to install laminated rubber bearings and other devices between the superstructure and foundation of the building to prolong the natural vibration period of the entire structural system, increase damping, and reduce the input to the superstructure. earthquake energy, to meet the expected earthquake requirements. However, since the integrated pipe gallery is an underground structure, and its surroundings are in direct contact with the soil, the same method of setting laminated rubber bearings as the above-ground structure is not only expensive, but also impractical.

Problems solved by technology

However, since the comprehensive pipe gallery is an underground structure, and its surroundings are in direct contact with the soil, the same method of setting laminated rubber bearings as the above-ground structure is not only expensive, but also impractical

[0003] Patent No. 200810046281.9 "Seismic Foundation" discloses a foundation body, concrete cover plate, foundation slab, downward inclined rod layer, upward inclined rod layer, upper longitudinal rod layer, upper horizontal rod layer, foundation pit floor, retaining wall , hardened steel cover plate, hardened steel support plate and hardened steel partition, this structure is obviously too complicated as the foundation structure of the comprehensive pipe gallery, the applicability is not high, and it will cause high cost, which is not conducive to popularization and implementation

[0004] Patent No. 201110069799.6 "Seismic Isolation and Damping Foundation and Construction Method for Rural Residential Buildings with Closed Constrained Sand Cushion" discloses a closed and constrained sand cushion seismic-isolation and damping foundation for rural residential buildings and its construction method. The comprehensive pipe gallery is buried in the soil and the surrounding structures that are in direct contact with the soil cannot play a good role in seismic isolation and shock absorption.

[0005] To sum up, the existing anti-seismic structure of the building foundation is too complex, which will incur high costs, and the existing anti-seismic structure of the building foundation is not suitable for the comprehensive pipe gallery, which is not conducive to the promotion and implementation of the problem
