Description
Technical Field
The utility model relates to a tunnel engineering disease punishment technical field, concretely relates to karst tunnel connects department to block up cleaning device.
Background
The distribution of the karst is very wide in China, and the karst occupies about one third of the land area in China. At present, the area of exposed carbonate rock is calculated to be approximately one tenth of the national land area. The blocking problem that tunnel drainage system appears during the operation is more common and causes the loss, because the condition that takes place to block up of the appearance of crystallization is more general in the tunnel in karst area, causes disease problems such as tunnel percolating water aggravation, lining cutting fall piece. At present, the knowledge and research on a drainage system of a karst tunnel are not fine enough, and the existing solution can not well solve the problem of blockage in a drainage pipe of the karst tunnel. Most tunnels in China do not consider structures and facilities for later inspection and maintenance of a drainage system, and once the drainage pipe is blocked, the clearing and maintenance are difficult to overcome.
SUMMERY OF THE UTILITY MODEL
The utility model discloses problem to prior art existence provides a karst tunnel joint department blocks up cleaning device.
The utility model adopts the technical proposal that: a blockage cleaning device at a karst tunnel joint comprises a placing box and a solution tank arranged in the placing box; the lower part of the solution tank is connected with one end of a liquid conveying pipe, and the other end of the liquid conveying pipe is communicated with a tunnel joint; an electromagnetic valve is arranged at the outlet of the lower part of the solution tank; the solution tank is internally provided with an oxalic acid dissolving agent.
Furthermore, the upper part of the solution tank is connected with an external liquid storage tank through a communicating pipe.
Furthermore, the outlet of the solution tank is connected with one end of the infusion tube through a first flange, and the other end of the infusion tube is connected with the tunnel joint through a second flange.
Further, the electromagnetic valve is connected with a control device.
Furthermore, a liquid level sensor for measuring the liquid level of the solution tank is arranged in the solution tank, and the liquid level sensor is connected with the control device.
Further, the placing box is hung on the inner wall of the tunnel through bolts.
Further, the infusion tube is made of ultra-high molecular weight polyethylene.
The utility model has the advantages that:
(1) the utility model can treat the crystallization blockage at the elbow without disassembly;
(2) the utility model discloses simple structure, convenient to use provide very big facility to later stage maintenance and maintenance, practiced thrift the cost.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-placing box, 2-solution tank, 3-oxalic acid dissolving agent, 4-electromagnetic valve, 5-bolt, 6-infusion tube, 7-tunnel joint, 8-first flange and 9-second flange.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the blockage clearing device for the karst tunnel joint comprises a placing box 1 and a solution tank 2 arranged in the placing box; the lower part of the solution tank 2 is connected with one end of a transfusion tube 6, and the other end of the transfusion tube 6 is communicated with a tunnel joint 7; an electromagnetic valve 4 is arranged at the lower outlet of the solution tank 2; an oxalic acid dissolving agent 3 is arranged in the solution tank 2. The concentration of the oxalic acid dissolving agent 3 can be configured according to actual conditions.
The upper part of the solution tank 2 is connected with an external liquid storage tank through a communicating pipe. The solenoid valve 4 is connected to a control device. A liquid level sensor for measuring the liquid level of the solution tank 2 is arranged in the solution tank and is connected with a control device. When the liquid level in the solution tank 2 is detected to be lower, the solution tank 2 is supplemented through an external liquid storage tank, and the liquid level can be supplemented through manpower or a pump. When the interior of the tunnel joint 7 needs to be cleaned, the control device controls the electromagnetic valve 4 to be opened, and the oxalic acid dissolving agent 3 in the solution tank 2 can flow into the tunnel joint 7 to clean crystals of the oxalic acid dissolving agent.
The outlet of the solution tank 2 is connected with one end of an infusion tube 6 through a first flange 8, and the other end of the infusion tube 6 is connected with a tunnel joint through a second flange 9. The placing box 1 is suspended on the inner wall of the tunnel by bolts 5. The first flange 8 and the second flange 9 are national standard-compliant flanges.
The infusion tube 6 is made of ultra-high molecular weight polyethylene. The ultra-high molecular weight polyethylene pipe is a wear-resistant, acid-resistant and corrosion-resistant pipeline material. The tunnel joint 7 can be a four-way joint or a three-way joint.
At the initial stage of tunnel operation, the electromagnetic valve 4 can be closed without cleaning the pipeline, and the electromagnetic valve 4 can be opened after a period of time to make the oxalic acid dissolving agent flow into the pipeline; the opening of the electromagnetic valve 4 can be controlled to enable the flow of the electromagnetic valve to be small, the opening of the electromagnetic valve 4 can be controlled to enable the flow of the electromagnetic valve to be increased if serious blockage occurs, and the electromagnetic valve is matched with a high-pressure water gun to clean.
When in use, the method comprises the following steps:
step 1: firstly, checking a tunnel drainage system, and observing whether the drain pipe elbow has the disease condition of crystallization blockage;
step 2: after the occurrence of clogging was confirmed, an oxalic acid dissolving agent was added to the solution tank 2.
And step 3: opening the electromagnetic valve 4 to enable the oxalic acid dissolving agent to flow into the tunnel joint 7 through the infusion tube 6 to dissolve crystals at the elbow;
and 4, step 4: when serious blockage occurs, the electromagnetic valve 4 can be completely opened, and a high-pressure water gun is matched to clean the pipeline;
and 5: closing the electromagnetic valve 4 and replenishing the oxalic acid dissolving agent.
The utility model has simple structure and convenient use, provides great convenience for later maintenance and repair, and saves cost; the crystallization blockage at the elbow can be treated without disassembly.
