Construction structure and construction method for underground passage crossing urban road

Abstract

The invention discloses a construction structure for an underground passage crossing an urban road. The construction structure comprises a first construction structure (110) and a second constructionstructure (120), wherein the first construction structure (110) comprises enclosure piles (1) and waterproof curtains (2); the tops of the enclosure piles (1) on the two sides are each provided with afirst crown beam (3); a thick reinforced concrete cover plate (4) is arranged between the first crown beams (3) on the two sides; a supporting device is arranged between the enclosure piles (1) on the two sides; the second construction structure is characterized in that a reinforced concrete support is arranged between crown beams at the top, and other structures of the second construction structure are the same as the corresponding structures of the first construction structure; and plain concrete cushion layers (9) are arranged below the first construction mechanism (110) and the second construction structure (120) in the underground passage. The invention further discloses a construction method for the underground passage crossing the urban road. According to the construction structureand construction method for the underground passage crossing the urban road, the passage sealing time is short during construction, the construction efficiency is high, and the structure is stable.

Description

technical field [0001] The invention relates to the field of underground passage construction, in particular to a construction structure and a construction method for crossing urban road underground passages. Background technique [0002] Currently, construction methods commonly used in the construction of underground passages or subway tunnels include large-scale excavation construction, and shield machine tunneling and pipe jacking construction methods. [0003] The traditional method is generally a large excavation construction method. First, the construction road surface is sealed, the surrounding piles are constructed, and then the earthwork is excavated to support the excavation, and then the lower road support is constructed to excavate the earthwork at the lower layer. This cycle is repeated from top to bottom. Digging until it reaches the bottom of the foundation pit, then constructing the underground passage structure, then backfilling the soil, and then constructi...

AI Technical Summary

Problems solved by technology

[0005] In the shield mechanical tunneling pipe jacking construction method, although the road closure construction can not be carried out and the normal traffic will not be affected, there are also the following problems, that is, this method can still be constructed when the structure size is small and the jacking distance is relatively short. As the size of the structure increases and the excavation distance increases, the hoisting equipment and jacking equipment will not be able to meet the construction needs

[0006] With the development of urban traffic and the increase of people's mobility, structures with small structural sizes can no longer meet the requirements of people's travel, and the demand for building underground passages and structures with large structural sizes is increasing. Therefore, a new construction structure for underground passages is urgently needed and construction method
