Problems solved by technology

[0005] The purpose of the present invention is to provide a long longitudinal slope secondary lining concrete construction equipment and construction method, to solve the problem of the secondary lining construction of a large longitudinal slope inclined shaft, due to the influence of the large longitudinal slope gradient, the secondary lining trolley is affected by its own gravity, etc. It is easy to cause the problem of the trolley slipping down, and it also solves the problem that when the second lining is constructed by the traditional straight method, due to the large slope of the inclined shaft, the second lining concrete is easy to flow downhill due to its own weight, and the joint with the upper version of the second lining appears. The top concrete pouring is not dense, forming construction cracks, which affects the strength of the secondary lining concrete and the overall stability of the tunnel

Abstract

The invention discloses large longitudinal slope second lining concrete construction equipment and a construction method. The equipment comprises a steel rail, a rail wheel, a steel mould trolley, a traction rope and a windlass, wherein the steel mould trolley moves on the steel rail through the rail wheel; the windlass is used for pulling the steel mould trolley through the traction rope; an outer wheel body and an inner wheel body are respectively arranged on two sides of the rail wheel, the outer wheel body is positioned outside the steel rail, the inner wheel body is positioned inside the steel rail, a first screw hole is formed in the outer wheel body, and a second screw hole is formed in the inner wheel body. The equipment has the beneficial effects that second lining is constructed through a reverse building method, concrete flows toward the downhill direction under the gravity effect when the concrete is poured, the concrete compactness at the second lining joint can be improved, the concrete pouring quality can be guaranteed, and previously poured second lining is in the downhill direction of newly poured second lining when construction is carried out by the reverse building method, so that the steel mould trolley can be supported, the trolley is prevented from sliding down, and second lining construction safety can be guaranteed.

Description

technical field [0001] The invention relates to the construction equipment and the construction method of the second lining concrete, in particular to the construction equipment and the construction method of the second lining concrete of the long longitudinal slope. Background technique [0002] The second lining of the tunnel generally refers to the first ring of concrete lining in the primary support of the tunnel. "Second lining" is a term in tunnel construction. When the tunnel is excavated, move forward along the face of the tunnel, and then the four sides of the tunnel that has been dug need to be reinforced. "Second lining" refers to the work that still needs to be reinforced for the second time around the reinforced tunnel. [0003] At present, the general tunnel secondary lining is constructed by advancing from the outside of the tunnel to the tunnel face. The construction direction of the secondary lining is the same as the excavation direction of the tunnel face...
