Example Embodiment

[0010] The examples are intended to illustrate the present invention and not to limit it in any way.

[0011] Take the applicant's construction of the North Tianshan Tunnel as an example:

[0012] (1) Project overview

[0013] The North Tianshan Tunnel is the main tunnel crossing the ridges of the North Tianshan Mountains. It is located in the Zhongshan District of the western section of the North Tianshan Mountains. . The elevation of Yueling Pass is 2780m, the relative height difference is 500~1200m, the exit section 500m is located on the downhill of 1‰, the exit section DK122+413~DK122+850 is on the Montmaral station line (437m), which is double It is a long-span tunnel, and the rest are single-track tunnels.

[0014] The applicant is constructing a production task of 7850m in the exit section of the main hole and 6770m of flat guide. The construction period of the flat guide is 20 months, and the construction period of the main hole is 36 months. Since the exit sectio...

Abstract

The invention relates to a high pressure water supply method for the long and large tunnel in cold areas, belonging to the technical field of tunnel construction, solving the problems of high cost and long water leakage detection time existing in water supply method for the long and large tunnel in cold areas in prior art. The high pressure water supply method is characterized in that a sump pit is positioned two hundred to three hundred meters in front of the tunnel face; a piece of pumping equipment is used to transport water in the sump pit to the tunnel face by a water flowing pipeline in order to be used in construction; the depth of accumulated water in the sump pit should submerge the pumping equipment; the water volume per unit time flowing into the sump pit is more than the water volume of the pumping equipment; as the tunnel face propels forward, the old sump pit is abandoned after new sump pit is positioned in front. The high pressure water supply method for the long and large tunnel in cold areas has the advantages of saving pipeline laying length, particularly that the long and large tunnel has a large number, saving construction and winter heat insulation of pools and pipeline outside the tunnel, saving the expense of long distance maintenance of pipeline by work force and quickening construction speed in the tunnel.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a method for high-pressure water supply in long tunnels in cold regions. Background technique [0002] Usually, the high-pressure water supply in the long tunnel adopts the alpine pool, and the water is pumped to the pool on the top of the mountain by the water pump, and then the water is sent to the cave through the pipeline for the construction of each tunnel face. In cold regions, it is usually necessary to insulate the pool and pipes. The problems with this method are: 1. The laying of pipelines is long; 2. The outside of the cave needs to be kept warm; 3. It takes a long time to check for water leakage. Contents of the invention [0003] The present invention provides a high-pressure water supply method for long tunnels in cold regions in order to solve the problems of high construction cost and long time for water leakage investigation in the exis...
