Description

Technical Field

[0001] This utility model belongs to the field of tunnel drainage technology, specifically relating to a small water collection pump-type reverse slope drainage control system. Background Technology

[0002] Tunnel reverse slope excavation is a major excavation method in tunnel engineering and is widely used. In tunnel reverse slope construction with complex geological and hydrological conditions, if groundwater at the excavation face is not drained in time, it will accumulate in large quantities, interfering with tunnel excavation and support construction, and even posing a risk of tunnel collapse. Therefore, in order to ensure the normal use and safety of the tunnel, it is essential to drain the groundwater accumulated at the tunnel excavation face in a timely manner during tunnel reverse slope excavation.

[0003] Existing technologies, such as Chinese Patent No. CN220185174U, disclose a tunnel reverse slope drainage system. This system uses an inner tank within the collection well, allowing for easier cleaning of sediment by simply removing the inner tank. However, in this technology, the lack of a filtration system within the inner tank when pumping water from the collection well results in sediment being easily drawn into the pump.

[0004] Therefore, a small-pump-collected reverse slope drainage control system is needed to solve the above problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a small water collection pump collection type reverse slope drainage control system to solve the problem that the water collection well in the prior art does not have a filtration system.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a small water collection pump-type reverse slope drainage control system, including several water collection wells arranged along the length of the tunnel. A water collection tank is installed in each water collection well. A filter cylinder is fixedly installed in the middle of the water collection tank. A filter screen is provided on the peripheral wall of the filter cylinder. A connection port is provided at the top of the filter cylinder. The connection port is connected to the water collection pump through a pipe. The pipe is sealed to the connection port.

[0008] Furthermore, the top of the filter cartridge is shaped like a frustum.

[0009] Furthermore, the bottom wall of the water collection tank is provided with a support platform, and the support platform is provided with a slot that mates with the bottom of the filter cartridge.

[0010] Furthermore, a gap is provided between the water collection tank and the inner wall of the water collection well.

[0011] Furthermore, the top of the water collection well is provided with an installation groove, and a guide plate is installed in the installation groove, which extends into the water collection tank.

[0012] Furthermore, the inner side of the guide plate is provided with an inclined section extending into the water collection tank.

[0013] The beneficial effects of this utility model are as follows: water in the tunnel flows into the water collection tank in the water collection well, and the filter screen set on the periphery of the filter cylinder can isolate the mud and sand outside the filter cylinder, so that the water flowing into the filter cylinder does not carry mud and sand. When the water in the filter cylinder is pumped out by the water collection pump, mud and sand can be prevented from entering the water collection pump. Moreover, when cleaning the mud and sand, the entire water collection tank can be pumped out of the water collection well.

[0014] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the following drawings are provided for illustration:

[0016] Figure 1 This is a cross-sectional view of the overall structure of this utility model.

[0017] The following are marked in the attached diagram: water collection well 1, installation groove 101, guide plate 102, inclined section 103, water collection tank 2, support platform 201, slot 202, filter cylinder 3, connection port 301, filter screen 4. Detailed Implementation

[0018] like Figure 1 As shown, this utility model provides a small water collection pump-type reverse slope drainage control system, including: a plurality of water collection wells 1 arranged along the length of the tunnel, a water collection tank 2 installed in the water collection well 1, a filter cylinder 3 fixedly installed in the middle of the water collection tank 2, a filter screen 4 provided on the periphery of the filter cylinder 3, a connection port 301 provided at the top of the filter cylinder 3, the connection port 301 being connected to the water collection pump (not shown in the figure) through a pipe (not shown in the figure), and the pipe being sealed to the connection port 301.

[0019] In this scheme, water in the tunnel flows into the water collection tank 2 in the water collection well 1. The filter screen 4 set on the periphery of the filter cylinder 3 can isolate the mud and sand outside the filter cylinder 3, so that the water flowing into the filter cylinder 3 does not carry mud and sand. When the water in the filter cylinder 3 is pumped out by the water collection pump, the mud and sand can be prevented from entering the water collection pump. And when cleaning the mud and sand, the water collection tank 2 can be pumped out of the water collection well 1 as a whole.

[0020] In one embodiment of this utility model, the top of the filter cylinder 3 is shaped like a frustum, so that when the water volume in the tunnel is large, the water and sediment impacting the top of the filter cylinder 3 can flow into the water collection tank 2 along the top of the filter cylinder 3.

[0021] In one embodiment of this utility model, the filter cartridge 3 is detachably connected to the bottom wall of the water collection tank 2.

[0022] In one embodiment of the present invention, the bottom wall of the water collection tank 2 is provided with a support platform 201, and the support platform 201 is provided with a slot 202 that cooperates with the filter cartridge 3.

[0023] In this solution, when installing the filter cartridge 3, the filter cartridge 3 is inserted into the slot 202 to achieve the positioning of the filter cartridge 3.

[0024] In one embodiment of this utility model, a gap is provided between the water collection tank 2 and the inner wall of the water collection well 1 to reduce the friction between the water collection tank 2 and the inner wall of the water collection well 1 when the water collection tank 2 is lifted.

[0025] In one embodiment of the present invention, the top of the water collection well 1 is provided with an installation groove 101, and a guide plate 102 is provided in the installation groove 101, the guide plate 102 extending into the water collection tank 2.

[0026] In this scheme, by setting an installation groove 101 and installing a guide plate 102 in the installation groove 101, the height of the guide plate 102 is not more than the height of the installation groove 101, so that water in the tunnel can flow into the water collection tank 2 through the guide plate 102, which facilitates water collection and avoids water flowing into the water collection well 1, which would cause sediment in the water collection well 1 to be difficult to clean. During installation, the water collection tank 2 is first placed into the water collection well 1, and then the guide plate 102 is fixed in the installation groove 101, so that the inner side of the guide plate 102 extends into the water collection tank 2.

[0027] In one embodiment of this utility model, the inner side of the guide plate 102 is provided with an inclined section 103 extending into the water collection tank 2, so as to facilitate the flow of water into the water collection tank 2.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
