Rapid box dam device for underground reservoir and manufacturing method thereof

Abstract

The invention discloses a rapid box dam device for an underground reservoir. The rapid box dam device comprises a top plate, a trapezoidal dam body and an artificial dam body, wherein the trapezoidaldam body is arranged at the bottom of the top plate; the artificial dam body is arranged at the bottom of the trapezoidal dam body; the artificial dam body is assembled by dam body modules a and b; 1 / 4 cylindrical water diversion channels are arranged on four parallel sides of the dam body modules a and b respectively; a sliding shaft is arranged at the middle part of the front side of the dam body module b; the side inclination angle above the trapezoidal dam body is the same as the top brushing angle of the top plate, and the angles are 4 to 7 degrees respectively; and a sliding passage forthe sliding shaft to slide is formed in the bottom of the trapezoidal dam body. The invention also discloses a method for manufacturing the rapid box dam device for the underground reservoir. The construction and drainage cost of the reservoir is greatly reduced, and the period and cost of constructing the reservoir are also reduced.

Description

technical field [0001] The invention relates to the field of underground reservoir construction, in particular to a rapid dam surrounding device for an underground reservoir and a manufacturing method thereof. Background technique [0002] In coal mining, it is important to store groundwater resources and build coal mine underground reservoirs, which will be used in the future through pumping pipelines, especially for water-scarce areas in the west. [0003] At present, the surface reservoir safety monitoring technology is perfect, including various dam body monitoring technical standards and regulations, such as the equipment technical conditions of the dam safety automatic monitoring system, the technical specifications for the safety monitoring of concrete dams and earth-rock dams, and the safety inspection of hydraulic steel gates and hoists Technical regulations, etc. In addition, the Ministry of Water Resources has also formulated a number of safety management regulati...

Problems solved by technology

However, the underground reservoir cannot be as good as that on the ground, and at the same time, the underground reservoir cannot tolerate failures such as water inrush. Therefore, the artificial dam body of the coal mine underground reservoir is very important. All the current artificial dam methods are piled up with sand and gravel underground. The artificial dam body takes 1-2 months from construction to use, which greatly increases the construction and drainage costs of the reservoir; and due to the unstable environment of the underground roadway, large-scale construction equipment cannot be transported underground. It is narrow, and it is impossible to provide space for large-scale construction equipment. At present, most of the water-proof materials for underground reservoirs in coal mines are piled with bricks, sand and pebbles, supplemented by secondary water-proof operations such as concrete spraying, so as to build the dam body The disadvantages such as slow speed, poor water-proof performance and poor water-proof effect on the top of the dam body are all displayed; rapid dam can bring huge economic benefits and safety guarantees

The invention patent with the application number CN201711223082.6 discloses a connection structure between the artificial dam body of the underground reservoir and the coal pillar dam body. This invention improves the connection strength and stability, and simplifies the construction process. The artificial dam body of the underground reservoir is difficult, the water-proof effect and sealing performance of the artificial dam body of the underground reservoir, and the long construction time
