Description

Technical Field

[0001] The invention relates to the technical field of underground pipe galleries, and in particular to a self-healing concrete underground pipe gallery with a waterproof sealing mechanism. Background Art

[0002] Underground pipe corridors, also known as underground urban pipeline integrated corridors, are an important part of urban infrastructure. As underground pipe corridors are located underground, in the subsequent use process, once the waterproof layer of the underground pipe corridor is corroded or damaged, it will cause water leakage problems. Once water droplets directly drip on the surface of pipes or cables, they will corrode the pipes and cables.

[0003] To this end, Chinese patent CN111945780B discloses an anti-leakage and anti-deformation underground pipe gallery, which is easy to install, has high construction efficiency, is very convenient to industrially disassemble, and improves the service life of the underground pipe gallery. It can ensure that the underground pipe gallery does not undergo horizontal displacement and deformation, and can effectively avoid serious accidents that may be caused by the movement of the underground pipe gallery, thereby threatening people's personal safety. It can reduce the impact and damage of groundwater and surface precipitation on the underground pipe gallery, and can play an effective role in preventing leakage and reducing drainage. At the same time, it has good adjustable flexibility. The size of the bottom drainage ditch on the main board in the drainage installation plate structure of the bottom end of the anti-lateral displacement plate is determined according to the surrounding precipitation conditions of the underground pipe gallery. According to the precipitation conditions in different areas where the underground pipe gallery is located, the size of the bottom drainage ditch in the drainage installation plate of the bottom end of the anti-lateral displacement plate can be adjusted according to local conditions to achieve a more efficient and timely precipitation discharge effect, and promptly solve the precipitation accumulation problem above and around the underground pipe gallery, which can play a relatively comprehensive anti-leakage effect.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 3 A self-healing concrete underground pipe gallery with a waterproof sealing mechanism comprises a main body 1 and a guide mechanism 2 arranged in the main body 1, at least two main bodies 1 are provided, adjacent main bodies 1 are interconnected to form an underground pipe gallery for accommodating cables and pipes, and the outer side of the main body 1 is wrapped with a self-healing concrete layer 11; the guide mechanism 2 comprises a water collecting trough 21 and a first adjusting component 22 for adjusting the position of the water collecting trough 21; the water collecting trough 21 is provided with a guide pipe 211 for drainage.

[0033] The present invention realizes the function of collecting water droplets and discharging water flow when the main body 1 seeps water through the main body 1 and the diversion mechanism 2, thereby protecting the pipes and cables in the main body 1, and flexibly adjusting the position of the water collection tank 21 through the first adjustment component 22, thereby stably collecting water droplets and preventing water droplets from corroding cables and pipes, solving the problem that once the water flow seeps into the pipe gallery, it is impossible to prevent the water flow from corroding the pipes and cables. A support seat 12 for fixing the diversion pipe 211 is provided on the inner wall of the main body 1, and the diversion pipe 211 is a hose to prevent the diversion pipe 211 from affecting the movement of the water collection tank 21, and a cable bracket 13 for supporting cables is also provided in the main body 1. During the laying of the pipe gallery, the pipe gallery can be firstly cast with concrete through a mold to form a single main body 1, and then multiple formed main bodies 1 can be spliced ​​together to achieve the laying of the pipe gallery. When casting concrete, self-healing concrete can be selected for casting to form a self-healing concrete layer 11 on the outside of the main body 1. The pipe gallery cast by self-healing concrete can automatically fill the cracked parts of the concrete locally during the later use, thereby improving the service life of the pipe gallery and effectively reducing the maintenance cost of the pipe gallery. Different from the traditional underground pipe gallery, the present invention sets a water collection tank 21 inside the pipe gallery, and adjusts the position of the water collection tank 21 through the first adjustment component 22 according to the position of the connection surface of the pipe gallery, so that the opening surface of the water collection tank 21 faces the connection surface of the main body 1. In summary, the present invention realizes all-round and high-efficiency waterproof protection from the source to the end through its unique design of the main body 1 and the diversion mechanism 2, and the flexible and adjustable water collection tank 21 system.

[0034] Reference Figure 1-Figure 3 : The first adjustment component 22 includes a guide tube 221 and a sliding tube 222. The guide tube 221 is connected to the water collecting tank 21, and the sliding tube 222 is connected to the inner wall of the main body 1. The guide tube 221 and the sliding tube 222 are slidably matched. The first locking component 23 is used to limit the sliding tube 222 from sliding along the guide tube 221.

[0035] The present invention realizes the function of controlling the movement of the water collection tank 21 through the guide tube 221, the slide tube 222 and the first locking assembly 23, so as to achieve the effect of accurately adjusting the position of the water collection tank 21, so that the water collection tank 21 can stably receive the water droplets that penetrate into the main body 1 from the connection of the main body 1. When adjusting the position of the water collection tank 21, the operator first releases the sliding restriction of the slide tube 222 by the first locking assembly 23, and then the operator moves the water collection tank 21, guides the movement of the slide tube 222 and the water collection tank 21 through the guide tube 221, and supports the water collection tank 21 through the guide tube 221. After the adjustment is completed, the movement of the slide tube 222 is restricted by the first locking assembly 23 to complete the fixation of the water collection tank 21, so as to avoid the problem that the water collection tank 21 moves by itself under the action of other unexpected external forces during the use of the pipe corridor, thereby affecting the waterproof performance.

[0036] Reference Figure 2-Figure 4 The first locking assembly 23 includes an insert rod 231 and a first elastic member 232.

The plurality of second slots 2221 are evenly spaced along a straight line direction. When the insert rod 231 is plugged into the second slot 2221 on the sliding tube 222, the sliding tube 222 is restricted from sliding along the guide tube 221.

[0037] The present invention realizes the function of limiting the sliding of the slide tube 222 through the insertion rod 231, the limiting ring 2311, the first elastic member 232, the first slot 2211 and the second slot 2221. When adjusting the position of the water collecting tank 21, first overcome the elastic force of the first elastic member 232 to pull the insertion rod 231 in the direction away from the guide tube 221 until the insertion rod 231 is separated from the second slot 2221, and then rotate the abutment rod 22312 so that the end of the abutment rod 22312 away from the limiting ring 2311 abuts against the guide tube 221, and then the limiting ring 2311 and the insertion rod 231 are limited by the abutment rod 22312 to reset under the elastic force of the first elastic member 232, and then slide the water collecting tank 21. After the water collecting tank 21 is moved to the specified position, pull the insertion rod 231, and then By rotating the abutment rod 22312, the movement restriction of the abutment rod 22312 on the insertion rod 231 and the limiting ring 2311 is cancelled, and the limiting ring 2311 is reset under the elastic force of the first elastic member 232. In order to ensure that the insertion rod 231 is plugged into the second slot 2221 on the sliding tube 222, the water collecting trough 21 and the sliding tube 222 are slid slightly. When the insertion rod 231 is aligned with one of the second slots 2221, the insertion rod 231 is inserted into the second slot 2221 under the elastic force of the first elastic member 232, thereby completing the fixation of the sliding tube 222 and the water collecting trough 21.
