Embodiment Construction

[0041]Taking a tunnel in southwest my country as an example, a comprehensive drainage water treatment system is adopted for the drainage in the tunnel. The comprehensive treatment system includes the external water interception system, the external drainage system, the tunnel waterproof system and the tunnel drainage system. The outer water interception system includes the water interception tank 31 on the outer ground 30 and the delivery pipeline from the water interception tank 31 to the water collection place. The outer drainage ditch 33, the tunnel waterproofing system includes a waterproof layer 41 arranged inside the lining 2, the first waterstop 5 arranged inside the lining 2 and the second waterstop 20 arranged inside the inverted arch 3, the tunnel drainage system includes The side drainage ditches 7 on both sides of the road surface 6 in the tunnel 1, the central drainage ditch 8 arranged at the central lower part of the road surface 6, the circumferential drainage pi...

Abstract

The invention discloses a construction method of a tunnel drainage and waterproofing comprehensive treatment system. The tunnel drainage and waterproofing comprehensive treatment system comprises an outer water interception system, an outer drainage system, a tunnel waterproofing system and a tunnel drainage system. The outer water interception system comprises a water interception groove on the outer ground and a conveying pipeline from the water interception groove to the water collecting position, the outer drainage system comprises an outer water resisting layer and an outer drainage ditch connected to the side, close to the tunnel portal, of the outer water resisting layer, the tunnel waterproofing system comprises a waterproofing layer arranged in a lining, and the tunnel drainage system comprises side drainage ditches on the two sides of the road surface in a tunnel and the like. By means of the outer water interception groove, the outer water resisting layer and the outer drainage ditch of the tunnel, collected water of a slope body on the upper part of the tunnel and a large amount of flowing water in the rainwater period are effectively drained and prevented; through a waterproofing layer, a first water stop belt, an annular drainage pipe and the like in the tunnel, flowing water in cracks and karst caves in the tunnel can be dredged and drained; and drainage holes are connected with the annular drainage pipe, so that water flow in the reinforced tunnel lining can be drained through a retaining wall.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a construction method of a tunnel drainage and water comprehensive treatment system. Background technique [0002] In tunnel construction, in order to ensure its normal operation, drainage facilities are usually installed in the tunnel, which can ensure the safety of the main structure of the tunnel during use, and extend and guarantee the service life. In the current tunnel construction, the drainage system of cast-in-place concrete is widely used, which not only has the problems of low construction efficiency and difficult quality assurance, but also easily leads to blockage of drainage pipes during the concrete pouring process. And after the drainage system is put into normal use, the concrete drainage ditches and concrete inspection wells poured on site are prone to cracking, causing water to enter the bottom of the tunnel, causing mud and other diseas...
