Description

Technical Field

[0001] The utility model relates to the technical field of slag soil treatment, in particular to an automatic water-pumping slag-water separation slag soil pool. Background Art

[0002] During underground construction projects like track construction and station excavation, large quantities of waste soil are generated. This soil often contains a certain amount of water. Without effective waste-water separation, this increases the load on transport vehicles, reduces the effective payload of each transport trip, and significantly increases transportation costs. Furthermore, during transportation, the high water content increases the fluidity of the waste soil, making it prone to leakage and spillage, polluting roads and the surrounding environment and increasing subsequent cleanup and maintenance costs.

[0003] The existing slag pit lacks a slag-water separation device. Due to the high water content of the slag, the slag in the slag pit cannot be dried and transported out for recycling. It can only be dehydrated by "natural drying" or "mechanical dehydration after adding industrial agents" before being transported out for recycling. Among them, the natural drying method is too inefficient, and the mechanical dehydration method after adding industrial agents is too costly.

[0004] In summary, the existing slag treatment methods have many problems in underground engineering construction such as track construction and station excavation. There is an urgent need for an efficient, convenient slag-water separation slag pool suitable for underground engineering construction sites to solve the problems of high slag water content affecting transportation efficiency and polluting the environment. Summary of the Invention

[0005] The purpose of the utility model is to provide an automatic pumping slag-water separation slag soil pool to solve the problems of poor slag-water separation effect and excessive slag water content in existing slag soil pools, and to meet the needs of green construction of underground projects such as track construction and station excavation.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] The invention discloses an automatic pumping slag-water separation slag soil pool, comprising a slag soil pool and a controller, wherein a deep pit is dug in a corner of the slag soil pool as a water storage area, and the bottom of the slag soil pool is provided with a longitudinal slope to ensure that the water in the slag soil can be smoothly separated from the soil and flow to the water storage area; a partition wall is constructed between the water storage area and the slag soil pool, and a water filter hole is provided at the bottom of the partition wall, and a water filter layer is installed in the water filter hole, and the water filter layer is used to filter impurities such as slag soil particles in the water flow; a water pump and a immersion water level gauge are installed in the water storage area, and the water pump and the immersion water level gauge are respectively connected to the controller through wires, and when the water level in the water storage area reaches the pumping line, the water pump automatically starts to pump water from the water storage area. A submersible water level gauge is a pressure sensor built into a measuring tube. When placed in water, the pressure of the water column acts on the measuring tube, transmitting this pressure to the pressure sensor. The pressure sensor measures the water level by measuring the applied pressure. A pumping line and a minimum liquid level are set within the water storage area. The pumping line is slightly lower than the bottom of the slag pit to prevent water from flowing back into the slag pit. When the water level reaches the pumping line, a pump automatically starts pumping water out of the water storage area, thereby quickly drying the slag. When the water level drops to the minimum liquid level, the pump automatically stops, preventing it from running dry.

[0008] Further preferred: the water filter layer is composed of galvanized wire mesh filled with pebbles and gravel, or composed of a drainage pipe filled with pebbles or gravel, the installation height of the outer side of the drainage pipe is controlled by the bottom surface of the slag pool, and a certain longitudinal slope is set to ensure that the water flow can hydraulically flow into the water storage area.

[0009] Further preferred: the water storage area is set in combination with the capacity of the slag pit and the size of the water pump, ensuring that the capacity of the water storage area is at least times the volume of the water pump.

[0010] Further preferably, the gradient of the longitudinal slope is 1%-3%.

[0011] This automatic pumping slag-water separation slag pit utilizes a sloped bottom and a water storage area to achieve natural separation of slag and water, improving separation efficiency. This system is particularly suitable for underground construction projects with limited space, enabling efficient slag-water separation within a smaller site and effectively addressing the issue of high slag moisture content hindering transportation efficiency. A pump and a submersible water level gauge are installed within the water storage area. These are connected to a controller via wires. The submersible water level gauge transmits water level signals to the controller, which automatically controls the pump to pump water, maintaining a low water level in the slag pit. This accelerates slag drying and reduces the time and cost of slag handling. For tight underground construction schedules such as track construction and station excavation, this system can effectively improve construction efficiency while preventing contamination of the construction site environment caused by high slag moisture content. The filter layer in the filter holes at the bottom of the partition wall effectively prevents slag particles from entering the pump, extending its service life. This system also ensures that the pumped water is clean, facilitating subsequent water recycling. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions of the invention are described clearly and completely below in conjunction with the embodiments. The described embodiments are only a part of the present invention, rather than all the embodiments. Example 1

[0019] A slag-water separation slag pit with automatic pumping comprises a slag pit 1 and a controller 7. A deep pit is dug in a corner of the slag pit 1 as a water storage area 4. The bottom of the slag pit 1 is provided with a longitudinal slope to ensure that the water in the slag can be smoothly separated from the soil and flow to the water storage area 4. A partition wall 2 is constructed between the water storage area 4 and the slag pit 1, and a water filter hole is provided at the bottom of the partition wall 2. A water filter layer 3 is installed in the water filter hole. The water filter layer 3 is used to filter impurities such as slag particles in the water flow. A water pump 5 and a immersion water level gauge 6 are installed in the water storage area 4. The water pump 5 and the immersion water level gauge 6 are respectively connected to the controller 7 through wires.

[0020] During construction, the slag pit 1 is first excavated according to the design requirements, and a small deep pit 0.5m-1.0m below the bottom is excavated in a corner as a water storage area 4. The water storage area 4 is set in combination with the capacity of the slag pit and the size of the water pump 5 to ensure that the capacity of the water storage area 4 is at least 4 times the volume of the water pump 5.

[0021] During the construction of the slag pit 1, an appropriate longitudinal slope of 1%-3% is set at the bottom of the slag pit to ensure that the water in the slag can be smoothly separated from the soil and flow to the water storage area 4.

[0022] A partition wall 2 is built between the water storage area 4 and the slag pool 1, and a water filter hole with a water filter layer 3 is set at the bottom of the partition wall. The water filter layer 3 is composed of galvanized wire mesh filled with pebbles and gravel, or a drainage pipe filled with pebbles or gravel. The installation height of the outer side of the drainage pipe is controlled by the bottom surface of the slag pool, and a certain longitudinal slope is set to ensure that the water can hydraulically flow into the water storage area 4.

[0023] When slag, silt, etc. are piled into the slag pool 1, the water in the slag will flow along the longitudinal slope to the water storage area 4. After being filtered by the filter water layer 3, the water in the water storage area 4 gradually accumulates.

[0024] A small water pump 5 is placed in the reserved water storage area 4, and a pumping line and a minimum liquid level are set. A submersible water level gauge 6 is placed in the water storage area 4 to accurately measure the water level there. When the water level in the water storage area 4 reaches the pumping line, a controller 7 automatically turns the water pump 5 on to pump water from the water storage area 4. When the water level drops to the minimum liquid level, the water pump 5 automatically turns off.

[0025] The above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the scope of protection of the present invention.
