Construction method for lateral penetration of building by shield

Abstract

The invention provides a construction method for lateral penetration of a building by a shield. The construction method specifically comprises the following steps: before the shield passes through, MJS construction method piles with angles of 15-30 degrees are constructed, a lower stratum of the building is reinforced, and plain concrete piles are adopted for isolation protection of a front area between the building and a tunnel; the middle of the plain concrete piles is drilled near the tunnel is drilled to embed sleeve valve pipes for isolation protection of un-engaged weak places of the plain piles; recharge wells are arranged around the building; water level, precipitation and inclination monitoring points are arranged around the building; in the shield tunneling process, shield parameters are controlled, and the monitoring points are used for monitoring; and after the tunnel is driven, small guide pipes are arranged in the tunnel near the building in a range of 120 degrees for grouting to prevent long-time accumulated influence on the building in later operation process. The construction method prevents the influence on the building by near-distance construction of the shielded tunnel, guarantees the structure stability of the building, and can effectively control the precipitation penetrating through the area.

Description

technical field [0001] The invention belongs to the field of urban rail transit engineering, and is specifically a kind of shield machine for reinforcing the position between the building and the building and the tunnel when the shield machine passes through the building at a short distance, and specially setting the parameters of the shield machine The construction method of passing through buildings at short distances. Background technique [0002] In recent years, the development and construction of urban underground space, which is dominated by rail transit construction in the country, is in the ascendant. The number of projects using shield construction such as urban comprehensive utility corridors, power and water conservancy tunnels, and highway and railway tunnels has gradually increased. While the market is expanding, shield construction Technology also has higher and higher requirements. Since most shield constructions are in densely populated areas, it is inevita...
