Description

Technical Field

[0001] This invention relates to the field of waterproofing devices, specifically a waterproofing device for underground holes applicable in multiple scenarios. Background Technology

[0002] With the improvement of my country's economic situation and development level, cities are under rapid construction. At the same time, more and more cities are starting to develop urban underground space. The application of monitoring of the surrounding environment and support structure is becoming more and more widespread. During the expansion and construction of urban above-ground and underground space, the safety assessment of the project body, surrounding rock and soil and the surrounding environment is very important. In order to ensure the safety of the project body, surrounding rock and soil and the surrounding environment during construction, technological and automated real-time monitoring methods are now used to control construction safety. Automated monitoring only needs to be installed and tested on site for the first time. After that, the equipment will transmit wireless signals for a long time, which is not affected by complex weather conditions, remote project sites and traffic restrictions. However, the (waterproof) protection of automated components has always been a problem. The components may be damaged or interfered with by the external environment, construction machinery and other factors, which cannot guarantee the monitoring accuracy.

[0003] Furthermore, during the construction of deep foundation pits, dewatering within the pit may cause changes in the surrounding water level. Monitoring the groundwater around the foundation pit is crucial for the safety assessment of the project itself, the surrounding soil and rock, and the surrounding environment. Traditional water level protection covers, installed in low-lying areas, are susceptible to damage from long-term use of water for safe and civilized construction and rainwater. This water seeps into the water level pipe along the side wall of the cover, affecting the accuracy of water level monitoring. When the water level protection cover is open for monitoring, surface water can easily flow back into the water level pipe through the opening, causing the monitoring data to become invalid. Therefore, there is an urgent need to design a waterproofing device for underground cavities that can be applied in multiple scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide a waterproofing device for underground holes with multiple application scenarios, so as to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0006] This invention provides a waterproofing device for underground holes with multiple application scenarios. It is suitable for underground holes in various scenarios and prevents the inflow of various liquids. It can be used as a sealing device for groundwater level, installation of automated monitoring components, and keeping underground chambers dry. In particular, it solves the problem of opening underground holes without water entering when there is water on the road surface.

[0007] Specifically, it includes:

[0008] Bottom support structure;

[0009] And the upper waterproof structure;

[0010] The bottom support component includes a base plate, and a through hole is provided at the center of the top of the base plate. A sleeve component is provided above the through hole on the top of the base plate.

[0011] The upper waterproof structure includes an outer connecting sleeve and a pull-out waterproof cylinder disposed inside the outer connecting sleeve. A second waterproof sealing ring is provided on the inner wall of the outer connecting sleeve, and a third waterproof sealing ring is provided on the outer wall of the pull-out waterproof cylinder below the second waterproof sealing ring. A protective cover is provided on the top of the pull-out waterproof cylinder.

[0012] Preferably, the outer wall of the pull-out waterproof cylinder and the inner wall of the outer connecting sleeve are both provided with mutually cooperating retaining balls, and the retaining balls are made of rubber.

[0013] Preferably, the top of the base plate is provided with a mounting ring, and the outer wall of the mounting ring is detachably connected to the inner wall of the outer connecting sleeve by threads.

[0014] Preferably, the sleeve assembly includes a water-locking sleeve fixed to the top of the base plate, and a waterproof sealing sleeve is provided on the inner wall of the water-locking sleeve. A first waterproof sealing ring is provided on the inner wall of the waterproof sealing sleeve, and a monitoring tube is fixed on the inner wall of the first waterproof sealing ring.

[0015] Preferably, the top of the protective cover has an arc-shaped groove, and the inside of the arc-shaped groove is rotatably connected to a handle via a rotating shaft.

[0016] Preferably, the protective cover has a connecting lock inside that connects to the top of the pull-out waterproof cylinder, and the top of the protective cover has a lock hole for unlocking the connecting lock.

[0017] Preferably, the base plate, outer connecting cylinder, pull-out waterproof cylinder, protective cover, and water-locking sleeve are all made of stainless steel.

[0018] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0019] The present invention provides a pull-out waterproof cylinder that can slide up and down inside the outer connecting sleeve, and a protective cover is installed on the top of the pull-out waterproof cylinder. Once there is a certain depth of water accumulation on the ground, the entire pull-out waterproof cylinder can be lifted up so that the top of the pull-out waterproof cylinder is higher than the water accumulation on the ground. At this time, a special disassembly device is used to open the protective cover, thereby ensuring that water will not enter the underground hole, and the use effect is good.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] Please see Figures 1-10 A waterproofing device for underground cavities with multiple application scenarios, comprising:

[0036] Bottom support structure 1;

[0037] And the upper waterproof structure 2;

[0038] The bottom support assembly includes a base plate 11, and a through hole 12 is provided at the center of the top of the base plate 11. A sleeve assembly 14 is provided on the top of the base plate 11 above the through hole 12.

[0039] The upper waterproof structure 2 includes an outer connecting sleeve 21 and a pull-out waterproof cylinder 22 disposed inside the outer connecting sleeve 21. The pull-out waterproof cylinder 22 can slide up and down inside the outer connecting sleeve 21. A second waterproof sealing ring 23 is provided on the inner wall of the outer connecting sleeve 21, and a third waterproof sealing ring 24 located below the second waterproof sealing ring 23 is provided on the outer wall of the pull-out waterproof cylinder 22. A protective cover 25 is provided on the top of the pull-out waterproof cylinder 22.

[0040] Furthermore, both the outer wall of the pull-out waterproof cylinder 22 and the inner wall of the outer connecting sleeve 21 are provided with mutually cooperating retaining balls 26, and the retaining balls 26 are made of rubber.

[0041] Furthermore, the top of the base plate 11 is provided with a mounting ring 13, and the outer wall of the mounting ring 13 is detachably connected to the inner wall of the outer connecting sleeve 21 by threads.

[0042] Furthermore, the sleeve assembly 14 includes a water-locking sleeve 141 fixed to the top of the base plate 11, and a waterproof sealing sleeve 142 is provided on the inner wall of the water-locking sleeve 141. A first waterproof sealing ring 143 is provided on the inner wall of the waterproof sealing sleeve 142, and a monitoring tube 144 is fixed on the inner wall of the first waterproof sealing ring 143.

[0043] Furthermore, the top of the protective cover 25 is provided with an arc-shaped groove 3, and the inside of the arc-shaped groove 3 is rotatably connected to a handle 4 via a rotating shaft.

[0044] Furthermore, the protective cover 25 is provided with a connecting lock inside that connects to the top of the pull-out waterproof cylinder 22, and the top of the protective cover 25 is provided with a lock hole 6 for unlocking the connecting lock.

[0045] Specifically, in use, this device includes, but is not limited to, waterproofing the groundwater level or waterproofing the automated monitoring components. The operating principle is the same. However, if a groundwater level pipe already exists, the monitoring pipe 144 in the device is not needed, and the rest of the structure does not need to be changed. The following is a detailed process description based on the presence of the monitoring pipe 144 in the device:

[0046] S1: First, use a drilling tool to drill a pre-embedded pit with a diameter of φ200mm and a depth of 150mm. The pre-embedded hole is cylindrical in shape, but not limited to cylindrical shape.

[0047] S2: After the pre-embedded pit is opened, a base plate 11 with a through hole 12 in the center is placed at the bottom of the pre-embedded pit. The base plate 11 is the same shape as the pre-embedded pit, and its outer side is the same as the inner sidewall of the pre-embedded pit. The through hole 12 in the center of the base plate 11 has a certain diameter, which is the same as the hole of the groundwater level (if there is a groundwater level pipe, the diameter of the through hole 12 on the base plate 11 is the same as the outer diameter of the groundwater level pipe, so that the through hole 12 on the base plate 11 can be used to install the groundwater level pipe).

[0048] S3: When installing the base plate 11, the sleeve assembly 14 on the base plate 11 is directly above the groundwater level hole. The inner diameter of the monitoring pipe 144 is the same as the diameter of the groundwater level hole. If there is a low water level pipe, the monitoring pipe 144 is removed, so that the waterproof sealing sleeve 142 and the third waterproof sealing ring 24 inside the water-locking sleeve 141 will be sleeved on the outside of the groundwater level pipe, thereby completing the installation of the entire bottom support structure 1.

[0049] S4: The outer connecting sleeve 21 is threaded to the outside of the mounting ring 13 by means of the mounting ring 13, so that the outer connecting sleeve 21 and the base plate 11 can be detachably connected, which facilitates subsequent maintenance or replacement of different models of base plates 11.

[0050] S5: After the connection is completed, the bottom support structure 1 and the upper waterproof structure 2 are installed as a whole. At the same time, the entire device is inside the pre-embedded pit, and the gap between the pre-embedded pit and the device is filled with concrete to make it dense.

[0051] S6: When the groundwater level hole needs to be used, if there is no water accumulation on the ground, the protective cover 25 can be opened directly. The protective cover 25 and the pull-out waterproof cylinder 22 are locked together by a connecting lock. The connecting lock is existing technology and is not shown in the figure. It can be opened using a special locking structure and disassembly device (the lock hole 6 in the figure is only for illustration). However, if there is water accumulation of a certain depth on the ground, the handle 4 can be rotated out through the slot 5, and then the handle 4 can be lifted up, causing the handle 4 to drive the protective cover 25 and the entire pull-out waterproof cylinder 22 to rise. When the pull-out waterproof cylinder 22 rises to a certain extent, the locking ball 26 on the outside of the pull-out waterproof cylinder 22 will move to the top of the locking ball 26 on the inner wall of the outer connecting sleeve 21, such as... Figure 8 As shown, this causes the top of the pull-out waterproof cylinder 22 to be higher than the water on the ground. At this time, a special disassembly device is used to open the protective cover 25 to ensure that water does not enter the underground hole. After use, the protective cover 25 is tightened again using the special disassembly device, and the pull-out waterproof cylinder 22 is lowered to the initial position by pressing it, thus solving the problem of opening the underground hole without water entering when the road is flooded.

[0052] Furthermore, it is worth mentioning that the second waterproof sealing ring 23 and the third waterproof sealing ring 24 of this device can provide double waterproof sealing, so that water will not enter the gap between the outer wall of the pull-out waterproof cylinder 22 and the inner wall of the outer connecting sleeve 21 during the lifting and lowering process. At the same time, the waterproof sealing sleeve 142 and the first waterproof sealing ring 143 serve as a further sealing line in case water enters the gap, so as to further prevent water from flowing into the interior of the bottom hole, resulting in good performance.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
