[0001] This application relates to the technical field of tunnel support, and particularly to a funnel-shaped sewage regulating tank. Background Art

[0002] Currently, with the in-depth development of water conservancy project construction, the geological conditions of tunnels have become diversified and complex. When a tunnel passes through a water-rich section or a strongly water-rich section, a large amount of water gushing will occur during tunnel excavation. The water gushing in the tunnel is characterized by a large flow rate and a high mud content, making it difficult to handle. Traditional regulating tanks need to be shut down for silt cleaning. If the water gushing treatment is not timely, it will lead to overflow, and the discharged water that does not meet the standards will cause pipeline blockage, all of which will have an adverse impact on the construction progress.

[0021] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0022] As Figure 1 , Figure 2 shown, the funnel-shaped sewage regulating tank includes a regulating tank main body 1, an influent channel 2, a square funnel 6, and a sludge discharge pipe 7. The regulating tank main body 1 is of a funnel-shaped structure, and the bottom is inclined to form a sedimentation port, and the sedimentation port is communicated with the sludge discharge pipe 7. The sludge discharge pipe 7 extends to the outside of the regulating tank main body 1 and is connected to the pressure filtration system, and a slurry pump 8 is installed on the sludge discharge pipe 7. An overflow port 5 is opened on the side wall at the upper end of the regulating tank main body 1, and a filter plate is installed at the overflow port 5 to prevent sediment from overflowing from the regulating tank.

[0023] The influent channel 2 is erected above the regulating tank main body 1, and a square funnel 6 is erected directly below the influent channel 2. The capacity of the funnel is determined according to the sewage volume. The square funnel 6 is erected in the middle of the regulating tank based on a support frame 9, and the support frame 9 is horizontally erected across the top of the sewage regulating tank. The square funnel 6 is erected on the top of the regulating tank main body 1 and is higher than the regulating tank main body 1. The square funnel 6 extends to the middle and lower part of the sewage regulating tank, forming a sludge treatment space and a discharge space after the sludge treatment is completed. The gushing water directly enters the square funnel 6 from the influent channel 2 and flows into the sludge treatment space below the regulating tank main body 1 through the square funnel 6.

[0024] The front end of the influent channel 2 is connected to the chemical agent channel 4. The chemical agent channel 4 is used to add flocculant to the gushing water, so that the soil in the gushing water coagulates and settles, and then the mud and water are separated. Due to the existence of the double electric layer, when an ionic solution with different electrical properties is added to the colloidal particles, coagulation will occur. When coagulation occurs, the colloidal particles will lose their stability or electrical neutrality, and the unstable colloidal particles will collide with each other again to form larger particles. After adding the flocculant, ionization will occur, forming valence bonds with the ion surface. In order to overcome the repulsive force between ions, flocculants will be generated due to stirring and Brownian motion among the particles. When the particles gradually approach, hydrogen bonds and van der Waals forces promote the particles to form larger particles. Once the collision starts, the particles begin to coagulate through different physical and chemical actions, and the larger particles are separated from the water and settle.

[0025] In a specific embodiment, the working process of this application includes:

[0026] Build a rectangular uncovered reinforced concrete regulating tank, process the steel plate into a square funnel 6 and place it in the regulating tank, making the funnel slightly higher than the wellbore by 40 - 50 cm. Harden the foundation of the regulating tank and the funnel. Set up a maintenance passage 3 to ensure the access of personnel up and down and later maintenance. During the construction of the regulating tank, steel ladder embedments are respectively pre-embedded inside and outside the well wall. In order to fix the middle funnel, steel plates need to be pre-embedded when pouring the bottom slab of the regulating tank, facilitating the welding of the fixing steel profiles; Open a hole with a size of 50 cm × 50 cm on the upper side of the water regulating tank to facilitate the treated water to be discharged. A sleeve is pre-embedded at the lowest point of the bottom of the regulating tank, so that the sediment after adding the flocculant to the funnel-shaped sewage regulating tank is discharged through a steel pipe.

[0027] An influent channel 2 is erected directly above the square funnel 6. The gushing water from the tunnel passes through the influent channel 2 and the square funnel 6 and enters the mud treatment area, separating from the treated water. The gushing water combines with the flocculant in the influent channel 2, continuously acts in the square funnel 6 and finally enters the mud treatment area. The flocculants are separated from the water and settle, accumulating at the bottom of the mud treatment area and connected to the filter press through the sludge discharge pipe 7. After the flocculants are deposited, the treated water meeting the discharge standard flows out after being filtered through the overflow port 5.

[0028] In an implementation manner of this embodiment, in order to further improve the automation of the regulating tank, reduce manual operation and improve the purification efficiency, the sewage regulating tank further includes a controller. A flow sensor is installed at the inlet end of the influent channel 2, an electromagnetic valve is installed at the front end of the chemical agent channel 4, and a flow sensor is installed at the rear end of the electromagnetic valve. The electromagnetic valve and the flow sensor are connected to the controller. The controller is also connected to the slurry pump 8 and the filter press on the sludge discharge pipe 7.

[0029] When the flow sensor in the influent channel 2 detects the ingress of gushing water, it transmits the gushing water flow data to the controller. The controller controls the opening of the solenoid valve in the chemical agent channel 4, enabling the flocculant to enter the influent channel 2, and adjusts the opening and closing of the solenoid valve based on the gushing water flow to control the flocculant flow. A delay program is set in the controller. After a period of time, it controls the opening of the slurry pump 8 and the filter press to complete the sludge treatment operation. When there is no gushing water discharged into the influent channel 2, the controller controls the shutdown of each device.

[0030] Finally, it should also be noted that in this article, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms including, containing, or any other variant are intended to cover non-exclusive inclusion, so that a process, method, article, or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article, or device.
