Shallow burial soil area shield driving stratum strengthening system and construction method thereof
The invention relates to a shallow burial soil area shield driving stratum strengthening system and a construction method thereof. Tunneling under the condition of shallow burial soil can lead to disadvantages of unstability and collapse of a shield method tunnel cutting face, upheaval and settlement of earth surface and the like. Uplift piles which are arranged in rows are vertically arranged between a two-way shield tunnel and the two sides of the two-way shield tunnel, the tops of the uplift piles at the two sides are provided with rectangular ring beams, and a two-way multi-ribbed plate is arranged in each ring beam; each two-way multi-ribbed plate is composed of concrete front-panels and two-way multi-ribbed beams which are arranged on the bottom faces of the concrete front-panels, and the two-way multi-ribbed beams are distributed in a transverse and longitudinal crossed grid-shaped mode; the concrete front-panels and the two-way multi-ribbed beams adopt integral formwork erection, and one-time pouring forming is achieved; the ring beams are connected with the two-way multi-ribbed plates to form a whole through rebar connectors reserved in the inner sides of the ring beams. According to the shallow burial soil area shield driving stratum strengthening system and the construction method thereof, stratum upheaval and settlement deformation caused by shield driving pressure under the condition of shallow burial soil can be effectively blocked, the adverse impact on a running tunnel below ground caused by temporary overload on the ground after completion of work can be reduced, and normal driving for the shield tunnel in the shallow burial soil area can be guaranteed.
