Problems solved by technology

When installing the drainage blind pipe, the location of the water seepage cannot be checked clearly, or the blind pipe is not fixed well, and the deviation occurs when the concrete is sprayed, which cannot achieve a good drainage effect and causes water leakage in the tunnel; ③The calcium content in the fissure water around the tunnel is relatively large, causing The tunnel waterproof and drainage system, especially the blockage of the diversion blind pipe, resulting in tunnel water leakage

Embodiment 1

[0016] In this embodiment, the water-rich bedrock tunnel seepage water grouting water blocking reinforcement material is composed of 30% CFB fly ash, 5% Mali powder, 15% cement, and 50% water. Firstly, CFB fly ash, cement, and water are evenly stirred by a high-speed vortex pulper at 300rmp for 1min to make them evenly mixed; then add Ma Lisan and evenly stirred by a high-speed vortex pulper at 200rmp for 30s to obtain water-rich bedrock Tunnel seepage water grouting water plugging reinforcement material.

[0017] The method of using the leakage water grouting water blocking reinforcement material for the above-mentioned water-rich bedrock tunnel: use a graduated container to collect and measure, install it on the inner surface of the tunnel for the specified measurement, introduce the leakage water into the measurement container, and then calculate 24h leakage water volume, and determine the location (coordinates) of the leakage water; quincunx-shaped drill holes are arranged...

Embodiment 2

[0022] In this embodiment, the water-rich bedrock tunnel seepage water grouting water blocking reinforcement material is composed of 40% CFB fly ash, 5% Mali powder, 5% cement, and 50% water. Firstly, CFB fly ash, cement, and water are evenly stirred by a high-speed vortex pulper at 300rmp for 1min to make them evenly mixed; then add Ma Lisan and evenly stirred by a high-speed vortex pulper at 200rmp for 30s to obtain water-rich bedrock Tunnel seepage water grouting water plugging reinforcement material.

[0023] The method of using the leakage water grouting water blocking reinforcement material for the above-mentioned water-rich bedrock tunnel: use a graduated container to collect and measure, install it on the inner surface of the tunnel for the specified measurement, introduce the leakage water into the measurement container, and then calculate 24h leakage water volume, and determine the location (coordinates) of the leakage water; quincunx-shaped drill holes are arranged ...

Embodiment 3

[0028] In this embodiment, the water-rich bedrock tunnel seepage water grouting water blocking reinforcement material is composed of 40% CFB fly ash, 10% cement, and 50% water. Mix CFB fly ash, cement, and water with a high-speed vortex pulper at 300rmp for 1 minute to make them evenly mixed to obtain water-rich bedrock tunnel leakage water grouting and water blocking reinforcement materials.

[0029] The method of using the leakage water grouting water plugging reinforcement material for the above-mentioned water-rich bedrock tunnel: use a square frame of a specified size with a sealing edge, install it on the inner surface of the tunnel for specified measurement, and introduce the leakage water into the measurement container , and then calculate the amount of water leakage in 24 hours, and determine the position (coordinates) of water leakage; arrange plum blossom-shaped drilling holes at 10cm in the leakage water area (cracks or cracks) of the tunnel working face, and then a...

Abstract

The invention discloses a water-rich bedrock tunnel leakage water grouting and water plugging reinforcing material and application thereof. The reinforcing material is formed by mixing 30-40 parts by mass of CFB fly ash, 0-5 parts by mass of Marithan, 5-15 parts by mass of cement and 50 parts by mass of water. The grouting and water plugging reinforcement material for the water-rich bedrock tunnel leakage water, prepared by the invention, has the advantages of good groutability and durability, high material strength, low water permeability coefficient and environmental protection. The application method has the advantages of high operability, high efficiency, economy and the like. According to the method, the treatment level of leakage water of the water-rich bedrock tunnel can be greatly improved, the treatment capacity of water diseases of the water-rich bedrock tunnel under construction and operation is fully improved, the service life of the water diseases of the water-rich bedrock tunnel under construction is fully prolonged, the lining of the water-rich bedrock tunnel can be safely and stably operated for a long time, and good economic, social and ecological benefits are generated.

Description

technical field [0001] The invention belongs to the technical field of leakage water grouting and water blocking reinforcement of water-rich bedrock tunnels, and in particular relates to a water-rich bedrock tunnel leakage water grouting water blocking reinforcement material and an application thereof. Background technique [0002] Carbonate strata in my country's mountainous areas are continuously distributed in sheets, karst is widely developed, karst geology and hydrogeological conditions are complex and changeable, groundwater migrates along the pipe-fissure-pore triple void medium, the disaster-causing ability is extremely strong, and it is easy to form a water-rich base Rock tunnel water leakage disease. Leakage water in water-rich bedrock tunnels is usually caused by (1) the development of rock joints and fissures in the tunnel leakage area, and the development of groundwater. The leakage water is bedrock fissure water, and the crack joints are locally distributed, and...
