Novel construction method for closing traffic in short time

Abstract

The invention relates to a novel construction method for closing traffic in a short time. The novel construction method comprises the following steps that the normal road traffic is closed, the closed road serves as a temporary construction site, and enclosure structures, water sealing systems and bracket stand column piles are constructed in the temporary construction site; the soil is excavated to the bottom elevation of a structural top board on the ground of the temporary construction site, rainfall systems are reserved, a formwork is laid, the structural top board is finished, and a pouring structure is reserved; according to the roadbed requirement, the soil is refilled on the structural top board, and normal traffic is recovered through compaction layer by layer. Monitoring points are arranged outside a pit, the rainfall systems are started for rainfall, an excavator enters the underground to excavate soil from passage inlets and outlets in the two sides of the road, and informatization construction is made according to monitored data. The construction of a structural bottom board, structural side walls and structural pillar main body structures is finished. The novel construction method can ensure the completion of self engineering, achieves improvement of the road surface traffic, and can carry out comprehensive improvement by combination with the program conditions of a municipal pipeline.

Description

technical field [0001] The invention relates to the technical field of underground construction, and is especially suitable for the occasion of underground construction under the condition of short-term closed traffic. Background technique [0002] Urban buildings are dense, traffic is heavy, and the utilization rate of land resources on the surface is already very high. Especially in the core areas of cities, every inch of land is expensive, which leads to bottlenecks in the development of many urban core areas. The development of underground space is an effective way to solve this problem. Underground space development is carried out on the lower side of the main road in the city. At present, the main construction methods are: open-cut method, underground excavation method and cover-excavation method. [0003] Among them, the open excavation method takes a long time, which has a great impact on road traffic, and it is difficult to control the deformation of surrounding bui...

AI Technical Summary

Problems solved by technology

In this construction method, the road traffic needs to be interrupted twice, and the cover plate still needs to be removed later, which is uneconomical, and all pipelines in the site area need to be relocated before the cover plate construction
