Embodiment 1

[0032] Such as figure 1 with figure 2 As shown, the drainage device for water seepage on the tunnel road surface of the present invention includes a tunnel, and also includes a drainage channel 2 provided on the road surface 11 with seepage holes 16 and communicated with the drainage ditch 12. The drainage channel 2 is embedded in the Inside the road surface 11 ; the top of the drainage channel 2 is provided with a filler layer 3 , and the top of the filler layer 3 is flush with the road surface 11 . The drainage channel 2 includes a drainage groove 21 and a U-shaped cover plate 22 arranged in the drainage groove 21 and matching the width of the drainage groove 21. The cover plate 22 is arranged opposite to the drainage groove 21, and the drainage groove 21 and the cover plate 22 surrounds and forms the drainage channel 2. The bottom of the drainage groove 21 is arc-shaped. The filler layer 3 is high-strength polyurethane elastic concrete. The water seepage hole 16 is pro...

Embodiment 2

[0035] Such as figure 2 As shown, this embodiment is a further improvement made on the basis of Embodiment 1. A waterproof layer is also provided between the drainage channel 2 and the filler layer 3; the waterproof layer includes a cement-based permeable crystalline waterproof coating layer 4 and the SR rubber caulking paste layer 5, the drainage channel 2 is connected to the filler layer 3 through the cement-based permeable crystalline waterproof coating layer 4 and the SR rubber caulking paste layer 5 in sequence.

[0036] Working principle: the thickness of the cement-based infiltration crystalline waterproof coating layer 4 is 10mm; the thickness of the SR rubber caulking paste layer 5 is 10mm; the present invention adopts double waterproofing measures of the cement-based infiltration crystalline waterproof coating layer and the SR rubber caulking paste layer The bottom can effectively prevent the water flow on both sides of the waterproof layer in the drainage tank, and...

Embodiment 3

[0038] Such as figure 1 with figure 2 As shown, the construction technology for tunnel pavement seepage drainage device of the present invention comprises the following steps:

[0039] a chisel the drainage groove: clean the road area water, find the water seepage hole 16, use the cutting equipment to cut out two parallel slits until the slit is connected with the drainage ditch 12, and chisel the concrete in the slit to form the drainage groove 21;

[0040]b plugging the seepage hole: judge the water flow of the seepage hole 16, if the water flow of the seepage hole 16 is greater than the water flow of the drainage channel 2, then use double liquid grouting to consolidate the seepage hole 16; if the water flow of the seepage hole 16 is less than the water flow of the drainage channel 2 If the water flow rate is too high, durable resin polymerization waterproof material is used to consolidate the seepage hole 16;

[0041] c Install the drainage channel: buckle the U-shaped ...

Abstract

The invention discloses a drainage device for tunnel pavement water seepage and a construction process thereof. The drainage device comprises a water seepage hole formed in a pavement and a drainage channel communicating with a drainage ditch, wherein the drainage channel is arranged in the pavement in an embedded mode, a packing layer is arranged at the top of the drainage channel, the top of thepacking layer is flush with the pavement, and the construction process comprises the following steps of drain tank chiseling, water seepage hole plugging, drainage channel mounting, waterproof layermounting and packing layer mounting. According to the device and the process, leakage water of the water seepage hole in the tunnel pavement is treated in a drainage-blockage combined mode, the problem of water seepage is solved fundamentally through blockage of the water seepage hole, even if the blockage of the water seepage hole fails, the leakage water can be drained to the drainage ditch through the drainage channel to be drained, and the service life is greatly prolonged under double measures, so that the problem of water seepage of the tunnel pavement is effectively solved, and the device is wide in applicability, low in manufacturing cost, convenient to construct, good in treatment effect, capable of ensuring tunnel operation safety to the maximum extent and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a drainage device for water seepage on a tunnel road surface and a construction process thereof. Background technique [0002] A road tunnel is a channel dedicated to vehicle transport. With the development of social economy and production, higher standards are put forward for road construction technology, requiring straight lines, gentle slopes, and spacious roads. Therefore, when the road passes through the mountainous area, the scheme of detour around the mountain in the past is mostly changed to the tunnel scheme. The construction of tunnels plays an important role in improving the technical status of highways, shortening running distances, increasing transportation capacity, and reducing accidents. The tunnel includes pavement, inverted arches, drainage ditches, wire ducts and tunnel side walls. However, due to the impact of surface water, 80% of the tunnels w...
