A tank membrane structure in a cave and a drainage method thereof

Abstract

The present invention provides a tank membrane structure in a cavern and a waterproofing and drainage method thereof, and relates to the technical field of waterproofing of underground cavern tank rooms. The tank membrane structure in the cavern comprises a tank, a membrane material is fixedly connected to the inner diameter of the top of the fixed bracket, a water tank is penetrated and arranged in the middle position of the top of the fixed bracket, and a fixed plate is fixedly connected to the inner diameter of the bottom of the fixed bracket. The push rod motor is operated to extend the top rod, drive the support plate to move upward, and push up and open the membrane material to avoid water accumulation on the membrane material. The dripping water from the mountain first falls on the membrane material, and the water flows into the water tank through the waterproof membrane material, and finally flows into the water collection tank through the downpipe through the water flow hole. When the membrane material is damaged, the water droplets will flow on the fixed plate, and the water will flow into the water tank through the water outlet weir groove through the conical fixed plate. The tank body is waterproofed in two layers by the membrane material and the fixed plate, which improves the waterproof effect and effectively protects the tank body.

[0012] S1. Installation

[0013] A fixing bracket is installed on the wall around the bottom of the dome on the inner wall of the top of the cave. The fixing bracket is an integrated structure with the water tank, fixing plate, push rod motor, water outlet weir, top rod and support plate. The mounting plate can be installed on the dome by threading it through the through hole with the inner wall of the top of the cave through the expansion bolt.

The tank body is waterproofed by two layers of measures through the membrane material and the fixed plate, which improves the waterproof effect and effectively protects the tank body; by turning the adjusting nut, the adjusting screw moves up or down inside the adjusting rod through the threaded action between the adjusting nut and the adjusting screw, and the distance between the membrane material and the dome of the cavern can be freely adjusted according to needs to adjust the tension of the membrane material, which is more convenient to use.

[0018] The present invention provides a tank membrane structure in a cavern and a drainage method thereof. It has the following beneficial effects:

[0019] 1. The present invention extends the push rod motor to drive the support plate to move upward, lift up and stretch the membrane material to avoid water accumulation on the membrane material. The dripping water from the mountain first falls on the membrane material, and flows into the water tank through the waterproof membrane material, and finally flows into the water collection tank through the downpipe through the water flow hole. When the membrane material is damaged, the water droplets will flow on the fixed plate, and the water will flow into the water tank through the water outlet weir groove through the conical fixed plate. The tank body is waterproofed by two layers of measures through the membrane material and the fixed plate, which improves the waterproof effect and effectively protects the tank body. The good waterproof and durable characteristics of the membrane material are utilized to collect the dripping water from the mountain and then collect it through the downpipe through the water tank for discharge, which plays a role in drainage.

[0020] 2. The present invention rotates the adjusting nut, and through the threaded action between the adjusting nut and the adjusting screw, the adjusting screw is moved upward or downward inside the adjusting rod.
