Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of municipal construction, in particular to a device and method for segmented water pumping of a full water underground cavern. BACKGROUND

[0002] With the rapid development of urban traffic, many old underground caverns are converted into civil air defense projects. However, due to the long use time of the underground cavern, the underground water level has fluctuated for a long time, causing the underground water to seep into the interior of the cavern, resulting in a full water cavern that cannot be used.

[0003] Currently, a large displacement water pump is usually used to pump water out of the full water cavern for a long time, and after the tunnel is emptied, the leakage points are monitored and reinforced. However, long-term and large-volume water pumping will cause the underground cavern in a balanced state to be out of balance, further damaging the cavern, and the cavern may collapse before the leakage points are checked and reinforced, which may further cause the ground to collapse and pose a threat to ground buildings, resulting in a large loss of financial and material resources. At the same time, storage and migration of long-term and large-volume water pumping also have difficulties, requiring a large amount of manpower and resources.

[0004] Therefore, how to safely pump water out of the full water cavern and check the leakage points has become a key and difficult point for the reinforcement and management of the underground cavern civil air defense project for reuse. SUMMARY

[0005] The purpose of the present application is to provide a device and method for segmented water pumping of a full water underground cavern, which realizes segmented water pumping of an underground full water cavern, safely empties the water in the cavern, and timely reinforces and manages. In order to achieve the above purpose, the present application solves the problem by the following technical scheme:

[0006] In a first aspect, the present application provides a device for segmented water pumping of a full water underground cavern, comprising:

[0007] A full-face partition device, comprising a water baffle adapted to the cross section of the cavern, the water baffle having a reserved drainage port;

[0008] A detection device for detecting the location of the leakage point of the underground cavern after water pumping;

[0009] A carrying device for carrying the full-face partition device to divide the cavern at a designated position of the full water underground cavern, provided with a drainage device connected with the drainage port, the carrying device being provided with a storage bin to carry the detection device into the designated position of the full water underground cavern.

[0010] As a further technical solution, the water baffle is formed by hinge connection of two plates, and an unfolding mechanism is arranged between the two plates.

[0011] As a further technical solution, the carrying device is provided with a plurality of mechanical arms that jointly cooperate to perform the water baffle partitioning hole chamber action.

[0012] As a further technical solution, the water baffle edge is wrapped with a sealing ring made of elastic material.

[0013] In a second aspect, the application provides a full water underground chamber segmented drainage method, which is performed by using a plurality of segmented drainage devices as described in the first aspect, and includes the following steps:

[0014] The length of the full water underground chamber is obtained, and a plurality of set length closed sections are preliminarily demarcated;

[0015] The water baffles are carried to the designated positions by the carrying device in sequence from inside to outside to perform the partitioning operation and support the hole chamber, and the closed sections are formed between the adjacent two water baffles;

[0016] The closed sections are drained one by one, the detection device carried into the closed section by the carrying device is used to detect and mark the leakage points, and after the drainage is completed, reinforcement and treatment are performed according to the marked points.

[0017] As a further technical solution, the closed sections are sequentially drained from outside to inside, the leakage points are detected after the first section is drained, the outer water baffles are removed to reinforce and treat the hole chamber, and this gradually advances to the deep part of the hole.

[0018] As a further technical solution, any closed section is selected for drainage according to needs, if there are other closed sections outside the section, the water in the section is then sequentially drained, if not, the water is directly drained, and after the water is drained, the water baffles continue to support the underground hole chamber until all the closed sections are drained.

[0019] As a further technical solution, the outermost water baffles are removed, the first section of the hole chamber is first reinforced and treated, and this is sequentially repeated.

[0020] As a further technical solution, the water baffles are folded and carried into the hole chamber, unfolded automatically after being carried to the designated position, and the partitioning operation is performed by operating the water baffles through the mechanical arms.

[0021] As a further technical solution, each segmented drainage device is controlled remotely.

[0022] The beneficial effects of the above application are as follows:

[0023] (1) The application divides the full water underground chamber into a plurality of closed sections by setting a plurality of full-section partitioning devices, can realize independent drainage of each arbitrary closed section, avoids the whole hole chamber being in a non-full water state during drainage, reduces the probability of further damage, and can detect the leakage points of the hole wall of the underground hole chamber in time through the detection device after drainage, so as to gain detection time.

[0024] (2) The water baffle of the present application not only has the function of blocking water, but also can be used as support of the hole wall. After drainage of a certain closed section, the water baffles on both sides play a major supporting role, reducing the probability of further damage to the underground chamber, and gaining time for subsequent detection and treatment.

[0025] (3) The present application can sequentially drain from the outside to the inside of the closed section. After the first section is drained, the leakage points are detected, the outer water baffles are removed, and the chamber is reinforced and treated, thereby gradually advancing to the deep part of the hole. This can not only achieve drainage, but also timely reinforcement and treatment.

[0026] (4) The present application can drain from any closed section. After all the closed sections are drained, the water baffles play a supporting role for the hole wall, and then the leakage points can be reinforced and treated in turn from the outside to the inside.

DETAILED DESCRIPTION

[0034] The technical solutions in typical embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] Example 1

[0036] like Figures 2 to 5 As shown, this embodiment provides a segmented pumping and drainage device for a water-filled underground cavern, comprising: a transport device 1, a full-section partition device 2, a detection device 3, a control device 4 and a power device 5.

[0037] like Figure 4 As shown, the full-section partition device 2 includes a water retaining plate 12 adapted to the cross-section of the cavern. The water retaining plate 12 is formed by two steel plates connected by a hinge 13, with an expansion mechanism provided between the two plates. The expansion mechanism is composed of a number of hydraulic cylinders 14. Driven by the hydraulic cylinders 14, the water retaining plate 12 is deployed. The hydraulic cylinders 14 are equipped with hydraulic lines 15 and loading valves 18. The hydraulic lines 15 are connected to the hydraulic cylinders 14, and the hydraulic cylinders 14 are loaded and extended by an external loading device. After loading is completed, the loading valves 18 located on the hydraulic lines 15 are closed.

[0038] The water retaining plate 12 is folded during transportation and unfolded to be assembled perpendicular to the axis of the cavern and parallel to the cross section of the cavern when it is used to retain water. The water retaining plates 12 of the two full-section partition devices form a drainage space, forming a closed section for rapid drainage.

[0039] The edge of the water retaining plate 12 is covered with a sealing ring 17 made of elastic material. In this embodiment, the sealing ring 17 is made of rubber. When the hydraulic cylinder 14 is loaded and stretched, the sealing ring 17 gradually contacts and fits tightly with the inner wall of the cave chamber to seal the water.

[0040] A drain port 16 is provided at the bottom of the water retaining plate 12, which is connected to the drain pipe 9 for pumping out the groundwater between the two full-section partition devices. It should be noted that the drain pipe 9 and the matching water pump are not necessarily fixed to the carrier 1 and can be set according to actual needs.

[0041] like Figure 2 As shown, the transport device 1 is used to transport and install the full-section cavern partition device 2, transporting the full-section partition device 2 to a designated location in a flooded underground cavern to partition the cavern. It comprises a power unit 5, crawler tracks 6, a robotic arm 7, a storage bin 8, a drainage pipe 9, and an underwater monitoring device 10.

[0042] The power device 5 provides power for the movement of the track 6, thereby driving the carrier device 1 to advance. The carrier device 1 is provided with a plurality of mechanical arms 7 that cooperate to perform the partitioning hole action of the water baffle 12. The mechanical arm 7 is a segmented flexible connection that can be rotated and bent at any angle. The mechanical arm 7 is provided with an electromagnetic chuck 11 around the front end joint, which realizes the installation of the full-face partitioning device 2. The mechanical arm 7 can be used with existing mechanical arms, and its specific structure and principle will not be described in detail here.

[0043] The storage bin 8 is located at the front end of the carrier device 1 and is used to store the detection device 3. The detection device 3 enters the designated position in the full-water underground chamber by being carried on the carrier device 1. The detection device 3 is used to detect the position of the water leakage point after the water is pumped out, thereby providing a mark for subsequent reinforcement and treatment.

[0044] The drainage pipe 9 is installed at the front end of the carrier device 1 and is connected with the drainage port 16. The drainage pipe 9 is provided with a drainage device such as a water pump, which can drain the water in the hole to the outside of the hole.

[0045] The underwater monitoring device 10 is located at the four corner points of the carrier device 1 and is used to monitor the operation of the entire carrier device 1.

[0046] As shown in Figure 2 , the control device 4 controls the movement of the carrier device 1, the operation of the mechanical arm 7, the loading of the hydraulic oil cylinder 14, the pumping and draining of water, and the shooting and detection of the underwater monitoring device 10 and the detection device 3. Through remote operation on the ground, the internal conditions of the chamber can be monitored in all directions, and the degree of intelligence is high.

[0047] Example Two

[0048] The embodiment provides a segmented water pumping and draining method for a full-water underground chamber, characterized in that a plurality of segmented water pumping and draining devices as in the first embodiment are used, and the method comprises the following steps, as shown in Figure 1 .

[0049] S101: The length of the full-water underground chamber is obtained by technical means, a plurality of set length closed sections are preliminarily demarcated, and the node positions of the closed sections are marked.

[0050] S102: The water baffle 12 is carried to the designated position by the carrier device 1 from inside to outside to perform the partitioning operation and support the chamber, and a closed section is formed between the two adjacent water baffles 12. Specifically, the closed section at the deepest part of the chamber is formed first, and the water baffles 12 are gradually arranged outward.

[0051] Since the sealing effect needs to be achieved, the outer edge (including the sealing ring 17) of the water baffle 12 needs to be slightly larger than the contour of the tunnel wall, and it is difficult to put it in as a whole. Therefore, the water baffle 12 is designed to be foldable, and the water baffle 12 is folded and carried into the chamber during transportation, and is automatically unfolded after being transported to the designated position, and the partitioning operation is performed by operating the water baffle through the mechanical arm 7.

[0052] One water baffle 12 is configured for one carrier 1. After the water baffle 12 is installed, the carrier 1 no longer moves. It can support the water baffle to prevent it from tipping over, and the drainage device on the carrier 1 controls the pumping and drainage.

[0053] S103: Drain the closed sections one by one, use the carrier 1 to carry the detection device 3 into the closed section to detect and mark the leakage points, and after the drainage is completed, reinforce the marked points.

[0054] There are two main methods for draining closed sections:

[0055] The first method involves draining the enclosed sections from the outside to the inside. After draining the first section, detect leaks, remove the outer water retaining plate 12, and reinforce the cavern, gradually progressing deeper into the cave. In other words, the first enclosed section (ordered from the outside to the inside, the same applies below) is drained first. After draining, the detection device 3 is used to detect leaks. The outer water retaining plate of this enclosed section is then removed and reinforced. This method is then used to treat the second enclosed section, the third enclosed section, and so on, until the last enclosed section.

[0056] The second type, such as Figure 5 As shown, any closed section is selected as needed to drain the water first. If there are other closed sections outside the section, the water in this section will be drained out. If there are no other closed sections, the water will be drained out directly. After draining the water, the water retaining plate will continue to support the underground cavern until all closed sections are drained. Remove the outermost water retaining plate, and first reinforce and manage the first section of the cavern. Similarly, remove and manage them one by one. Specifically, in some special occasions, you can first drain a certain section in the middle, such as the third section. At this time, when draining, the water needs to pass through the first and second closed sections in sequence until it is discharged from the cave. If the flow is well controlled, it can even ensure that the first and second closed sections are full of water during drainage.

[0057] However, it should be noted that although drainage can be started from any closed section, the closed section still needs the water retaining plate 12 as support to continue working after drainage. Therefore, it is necessary to reinforce the first closed section first, and then remove the water retaining plates in sequence. For example, when reinforcing the first closed section, the water retaining plate on the outside of this section is first removed, and the remaining water retaining plates serve as support. After the reinforcement and treatment is completed, the second water retaining plate is then removed, and so on, gradually advancing deeper into the cave until all the cave walls are reinforced and treated.

[0058] Although the present application has been disclosed with reference to the preferred embodiments, it is not intended to limit the present application, and any person skilled in the art can make possible changes and modifications to the technical solutions of the present application using the disclosed methods and technical contents without departing from the spirit and scope of the present application. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical solutions of the present application shall fall within the protection scope of the technical solutions of the present application.
