Description

Technical Field

[0001] This utility model belongs to the field of karst tunnel construction technology, and relates to a dust suppression device for circulating water in karst tunnel engineering. Background Technology

[0002] In karst tunnel construction, dust and soil treatment, as well as the efficient utilization of water resources, are pressing issues. Traditional dust suppression methods are inefficient and have low water utilization rates, failing to meet the environmental protection and efficiency requirements of modern construction. When encountering water accumulation in karst caves, the irregular shape of the caves and the turbidity of the water make it impossible to effectively extract and utilize the water. Current construction methods lack effective equipment to utilize karst cave water for dust suppression, resulting in water waste and poor dust suppression effects.

[0003] Therefore, it is necessary to design a device that can effectively extract water from karst caves, recycle water resources, and improve dust suppression, thus providing a good environment for tunnel construction. Utility Model Content

[0004] The purpose of this invention is to provide a circulating water dust suppression device for karst tunnel engineering, which can efficiently extract water from the karst cave for dust suppression.

[0005] The technical solution adopted in this utility model is a circulating water dust suppression device for karst tunnel engineering, including a water suction device, a water collection well, a mobile water tank, and a sewage collection tank. The sewage collection tank is fixed on one side of the mobile water tank. The water suction device, the water collection well, and the mobile water tank are connected in sequence by water pipes. A water pump A is installed at the inlet of the water pipe. A propeller A and a drive motor are installed below and above the water suction device. A retractable stainless steel corrugated pipe is vertically installed on the mobile water tank. One end of the retractable stainless steel corrugated pipe is located inside the mobile water tank, and a water pump B is installed at its port. The other end is located outside the mobile water tank, and a nozzle is installed at its port. Water baffles are installed around the nozzles. The bottom of the water baffles is fixed to the top of the mobile water tank and the sewage collection tank. Adjacent water baffles are fixedly connected on their sides. The inlet of the sewage collection tank is located inside the water baffles. The outlet of the sewage collection tank is connected to the inlet of the water collection well through a return water pipe.

[0006] The water suction device has water inlets around its bottom surface, each equipped with a filter screen, and an outlet on the side wall near the water collection well.

[0007] Sonar detectors are installed on the bottom and sides of the water suction device, and the sonar detectors are connected to the user terminal via a wireless network.

[0008] The water suction device is equipped with propeller B and a drive motor around its perimeter.

[0009] A filter box is installed at the inlet of the water collection well. A crossbeam is fixed to the top of the water collection well. A winding roller and a drive motor are installed in the middle of the crossbeam. A steel wire rope is wound on the winding roller. One end of the steel wire rope is fixed to the winding roller, and the other end is fixed to the top of the filter box.

[0010] Support bars are fixed on the inner walls of the left and right sides of the water collection well, and the distance between the two support bars is less than the length of the bottom of the filter box.

[0011] The mobile water tank and sewage collection tank are equipped with casters at the bottom.

[0012] Dust sensors are installed on the sidewalls of the retractable stainless steel corrugated pipe.

[0013] The water baffles around the nozzle are in the shape of an inverted four-sided pyramid.

[0014] A water valve is installed in the middle of the return water pipe.

[0015] The beneficial effects of this utility model are that it forms a water collection well circulating water dust reduction device for karst tunnel engineering, consisting of a water suction device, a water collection well, a mobile water tank, a nozzle, and a sewage collection tank. The water suction device draws in the water accumulated or gushing water in the karst cave, then transports it to the water collection well. After being filtered by a filter box, the water is pumped to the mobile water tank, and then sprayed into the tunnel through the nozzle to reduce dust in the tunnel. The water sprayed out by the nozzle finally enters the sewage collection tank through a baffle for recycling. It not only effectively utilizes the water accumulated in the karst cave, but also efficiently reduces dust in the tunnel. The structure is simple, easy to manufacture, and highly practical.

[0058] When using this utility model for dust suppression via circulating water in a karst tunnel engineering project, the water suction device 1 is placed in the accumulated water of the karst tunnel. The water suction device moves horizontally with the aid of a propeller and uses a sonar detector to detect the distance to the bottom and rock walls of the karst tunnel. After detecting the maximum distance to the bottom of the tunnel, the water suction device moves to the bottom of the karst tunnel to perform water suction. The suctioned water is first filtered through a filter screen, and then enters the filter box of the sump well for secondary filtration through a water pipe. The filtered water is then pumped by a water pump through a water pipe to a mobile water tank. The water in the mobile water tank is then transported to the nozzles for spraying through a retractable stainless steel corrugated pipe. At this time, the dust sensor on the retractable stainless steel corrugated pipe monitors the dust concentration of the surrounding environment in real time. When the concentration is lower than the set value, the water pump at the bottom of the stainless steel corrugated pipe stops working, pushing the mobile water tank 3 and the sewage collection tank 4 to move to the next area with a higher dust concentration to continue spraying water for dust suppression. During the spraying process, the sewage carrying dust is collected by a baffle plate and flows into the sewage collection box. The water in the sewage collection box is then transported back to the filter box in the collection well through the return water pipe, realizing the recycling of sewage. When the filter box is full of filter residue, all water pumps are turned off, and the filter box 7 is moved upward by the winding roller 5 to remove the filter residue. Then, the filter box 7 is moved downward to the inlet of the collection well 2 by the winding roller 5, and all water pumps are turned on, and the device resumes operation.
