Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of water collecting devices for the water leakage of foundation pit side wall. BACKGROUND

[0002] A foundation pit refers to one or more deep pits excavated on the ground, usually used for foundation treatment or development of underground space in construction engineering. The excavation of foundation pit is usually for the construction of underground structure, such as underground parking lot, underground shopping mall, basement, etc. During the excavation of foundation pit, factors such as underground water level, soil stability, influence of surrounding buildings, etc. need to be considered to ensure the safety and stability of the foundation pit. Support structures such as support walls, support piles, etc. are usually set up around the foundation pit to prevent the collapse of the side wall of the foundation pit.

[0003] Water leakage from the side wall of the foundation pit may be caused by various factors. First, when the underground water level is high, it will cause a certain water pressure on the side wall of the foundation pit, resulting in water seepage from the side wall. Secondly, if the waterproof measures of the side wall of the foundation pit are not in place or are damaged, water will also seep into the foundation pit from the side wall. In addition, if the soil around the foundation pit has strong permeability, water will more easily penetrate the side wall. The common solution is to use cotton or other permeable materials to plug the leakage and then reserve a hose for drainage, and then collect and discharge the water.

[0004] CN201921408706.6 discloses an automatic collection and discharge device for water leakage from the side wall of a foundation pit, which comprises a water tank, a leakage water collection pipe and a leakage water discharge pipe. The water tank is arranged in the foundation pit, one end of the leakage water collection pipe is arranged in the side wall of the foundation pit, the other end of the leakage water collection pipe is arranged in the water tank, and the leakage water collection pipe introduces the leakage water in the side wall of the foundation pit into the water tank. A water pump and a liquid level controller are arranged in the water tank, the water pump is electrically connected with the liquid level controller, and the liquid level controller controls the start and stop of the water pump. The water pump is connected with one end of the leakage water discharge pipe, and the other end of the leakage water discharge pipe is arranged in a water collecting well. The water pump introduces the water in the water tank into the leakage water discharge pipe and then into the water collecting well.

[0005] The above technical solution introduces water through the leakage water collection pipe into the water tank, and then discharges the water according to the liquid level in the water tank through the leakage water discharge pipe. However, water leakage from the side wall of the foundation pit may occur at one place or multiple places. If it occurs at multiple places, multiple automatic collection and discharge devices as described above need to be placed, which undoubtedly increases the cost and makes management more difficult. After use, the leakage water collection pipe and the closed water tank need to be removed, so a device that is easy to use is needed. UTILITY MODEL CONTENTS

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0017] Embodiment 1

[0018] Reference Figures 1 to 3 A water receiving device for water leakage of a foundation pit side wall, comprising a main pipe 2 arranged along the foundation pit side wall 1, a drainage module 3, a water receiving mechanism 4, an elastic assembly 5, and a water guide pipe 6, one end of the water guide pipe 6 is connected in the foundation pit side wall 1, the drainage module 3 is used for collecting and discharging water in the main pipe 2 to an externally provided water storage tank 8, a plurality of connecting pipes 21 are provided on the main pipe 2, the water receiving mechanism 4 is movably connected on the plurality of connecting pipes 21 respectively, the elastic assembly 5 is sleeved on the connecting pipe 21, one end of the elastic assembly 5 abuts against the water receiving mechanism 4, and the other end abuts against the main pipe 2, the inlet end of the connecting pipe 21 is located on the side surface, and the water receiving mechanism 4 is provided with a guide pipe 4111 which is in communication with the outside;

[0019] In the initial state, the water receiving mechanism 4 closes the inlet end of the connecting pipe 21;

[0020] When the water receiving mechanism 4 is compressed to compress the elastic assembly 5, the inlet end of the connecting pipe 21 enters the water receiving mechanism 4, the water guide pipe 6 can be in communication with the connecting pipe 21 through the guide pipe 4111, and the upward movement of the water receiving mechanism 4 is limited.

[0021] In this design, the water guide pipe 6 has one end connected in the foundation pit side wall 1 in the initial state, when water leakage occurs in the foundation pit side wall 1, the lower end of the water guide pipe 6 is inserted into the guide pipe 4111, at this time, the water receiving mechanism 4 can be pressed down by the other hand, or the hand holding the water guide pipe 6 can be forced down while being inserted into the guide pipe 4111, so that the water receiving mechanism 4 moves downward, it should be noted that the insertion depth of the water guide pipe 6 needs to be controlled to avoid being too deep, because the inlet end of the connecting pipe 21 is arranged on the side surface, after the elastic assembly 5 is compressed, the connecting pipe 21 will continuously move to the inside of the water receiving mechanism 4 relative to the water receiving mechanism 4, so that the inlet end of the connecting pipe 21 is located in the water receiving mechanism 4, by continuing to insert the water guide pipe 6 into the water receiving mechanism 4, the water guide pipe 6 can be in communication with the connecting pipe 21, and the upward movement of the water receiving mechanism 4 is limited.

[0022] It should be noted here that the pipe used by the water guide pipe 6 is a pipe with certain hardness, that is, when the water guide pipe 6 restricts the water receiving mechanism 4 to go up, the passage in the water guide pipe 6 will not be deformed.

[0023] After use, the water guide pipe 6 is directly pulled out, the elastic component 5 can drive the water receiving mechanism 4 to go up and close the inlet end of the connecting pipe 21, which is more flexible to control, simple and convenient to operate, and more economical.

[0024] It should be noted here that the cross section of the outlet end of the water guide pipe 6 is optimally elliptical, and the outlet end of the water guide pipe 6 is optimally pointed in the whole.

[0025] In this embodiment, the water receiving mechanism 4 includes an outer shell 41, the guide pipe 4111 is located on the outer shell 41, the outer shell 41 is movably connected with the connecting pipe 21, one end of the elastic component 5 abuts against the outer shell 41, and the top of the connecting pipe 21 is provided with a clamping block 211.

[0026] When the outer shell 41 compresses the elastic component 5 to go down, the water guide pipe 6 can enter the outer shell 41 through the guide pipe 4111 and be located below the clamping block 211, and the outlet end of the water guide pipe 6 is in contact with the clamping block 211 to restrict the outer shell 41 from going up.

[0027] Specifically, there are many ways to restrict the outer shell 41 from going up, the simplest one is to directly insert the outlet end of the water guide pipe 6 into the inlet end of the connecting pipe 21, and restrict the outer shell 41 from going up by clamping the water guide pipe 6 between the connecting pipe 21 and the outer shell 41, in order to increase the stability of the water guide pipe 6, the clamping block 211 is arranged on the top of the connecting pipe 21, so that when the water guide pipe 6 extends into the outer shell 41 and the inlet end of the connecting pipe 21 is located in the outer shell 41, the water guide pipe 6 can extend below the clamping block 211, and the clamping block 211 and the outer shell 41 tightly clamp the water guide pipe 6, thereby ensuring the stability of the water guide pipe 6.

[0028] More preferably, the water receiving mechanism 4 further includes an end cover 42, the end cover 42 covers the top of the outer shell 41, and a plurality of through holes 421 are arranged on the end cover 42. The end cover 42 can prevent some leaves blown by the wind from entering the outer shell 41, and the plurality of through holes 421 arranged on the end cover 42 can keep the air pressure inside and outside the pipe balanced, avoid negative pressure in the sealed state, and facilitate smooth drainage.

[0029] In the embodiment, the outer shell 41 comprises a first shell 411 and a second shell 412 which are integrally formed, the first shell 411 is a cylindrical structure, the second shell 412 is a funnel-shaped structure, the second shell 412 is movably connected with the connecting pipe 21, one end of the elastic assembly 5 is abuttingly connected with the second shell 412, the guide pipe 4111 is arranged on the first shell 411, and the guide pipe 4111 is arranged in an inclined manner and is connected with the inner wall of the second shell 412.

[0030] In actual use, the funnel-shaped second shell 412 can provide a guide slope for the water and the water guide pipe 6, first of all, the water guide pipe 6, by arranging the guide pipe 4111 on the second shell 412 and connecting the guide pipe 4111 with the inner wall of the second shell 412, when the water guide pipe 6 extends into the second shell 412 from the guide pipe 4111, the guide slope can provide support, and the water flowing out of the water guide pipe 6 can flow to the inlet end of the connecting pipe 21 through the guide slope and flow into the main pipe 2.

[0031] Optionally, the guide pipe 4111 is two and arranged symmetrically. The two guide pipes 4111 can provide an additional water receiving position, and the water receiving mechanism 4 does not need to be arranged particularly densely.

[0032] Preferably, the vertical section of the clamping block 211 is in an inverted trapezoidal structure, and the clamping block 211 can be completely fitted with the inner wall of the second shell 412, when the clamping block 211 is completely fitted with the inner wall of the second shell 412, the inlet end of the connecting pipe 21 is closed by the lower end of the second shell 412.

[0033] The vertical section of the clamping block 211 is arranged in an inverted trapezoidal structure, when the water guide pipe 6 is pulled out after use, the elastic assembly 5 is reset to lift the outer shell 41 and make the inner wall of the second shell 412 completely fitted with the clamping block 211, so as to ensure the sealing of the connecting pipe 21 when not in use.

[0034] In the embodiment, the drainage module 3 comprises a water tank 31 connected with the main pipe 2, a water level control module (not shown in the figure) connected in the water tank 31, and a drainage pipe 32 connected with the water tank 31, and a first pump 331 arranged on the drainage pipe 32, the water tank 31 is used to collect the water discharged from the main pipe 2 and deliver the water to an external water storage tank 8 through the drainage pipe 32.

[0035] After the main pipe 2 collects the water of the connecting pipe 21, the water is delivered to the water tank 31 through the main pipe 2, when the water tank 31 collects a certain amount of water and the water level reaches the preset high water level of the water level control module, the drainage is automatically triggered, the water is delivered to the external water storage tank 8 through the first pump 331, when the water level is lower than the preset low water level of the water level control module, the drainage is automatically closed, and manual drainage is not required.

[0036] It should be noted that the water level control module can be realized by a float ball valve.

[0037] More preferably, the water tank 31 is further provided with a filter screen 33. By adding the filter screen 33 in the water tank 31, the granular impurities or crawlers in the water discharged from the main pipe 2 can be isolated.

[0038] It should be noted that the water tank 31 shown in the figure is not the state of the water tank 31 in operation, and the purpose of opening the cover of the water tank 31 is to clearly see the filter screen 33 inside.

[0039] As a further optimization of the present embodiment, a cleaning module 7 is further included, which comprises a water supply pipe 71 and a second pump 72 connected with the water supply pipe 71. The two ends of the water supply pipe 71 are respectively connected with the external water storage tank 8 and the main pipe 2. The water supply pipe 71 pumps the water in the external water storage tank 8 from one end of the main pipe 2 into the main pipe 2, and enters the water tank 31 from the other end of the main pipe 2.

[0040] Because there will be mud or dust in the end cover 42 or the first shell 411 and the second shell 412 when it is raining or when the project is in progress, and there is also a possibility that small crawlers will enter and follow the water flowing into the main pipe 2. Because the length of the main pipe 2 is large, it is difficult to discharge these impurities, and the water falling into the water tank 31 through the filter screen 33 will be relatively clean, so the water transported to the water storage tank 8 will also be relatively clean. Under the action of the second pump 72, the water can enter the main pipe 2, and under the action of a certain water flow, the main pipe 2 can be cleaned.

[0041] Preferably, the elastic assembly 5 is a spring 51. The spring 51 has the advantages of good elasticity, light weight, long service life, easy installation, low cost, etc.

[0042] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
