Description

Technical Field

[0001] This utility model relates to the field of shield tunnel segment maintenance technology, specifically a maintenance device for repairing defects in shield tunnel segments. Background Technology

[0002] Shield tunnel segment defect repair refers to the process of repairing defects such as cracks, leaks, and damage that occur in tunnel segments during shield tunneling construction. Repair methods typically include steps such as surface cleaning, crack repair, waterproofing, and surface restoration to ensure the safety and durability of the tunnel structure. Repair materials often use high-strength, corrosion-resistant chemical materials such as epoxy resin and polyurethane. Sometimes, cement-based materials are also used for local repairs. The entire repair process needs to be designed according to the specific circumstances of the defect to achieve the best repair effect while minimizing the impact on normal construction.

[0003] After the defects of the tunnel lining segments are repaired, spray curing is usually required to ensure the quality of the material forming at the repair site. Traditional spray curing pools for tunnel lining segments do not have a filtration structure. Since there are dirt or waste materials attached to the repaired tunnel lining segments, after spraying, the dirt and waste materials are mixed into the water in the pool. When the water is recycled, the dirt and waste materials can easily cause blockage of the spraying pipeline. Utility Model Content

[0004] The purpose of this utility model is to provide a maintenance device for repairing defects in tunnel segments, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A maintenance device for repairing defects in tunnel boring machine (TBM) segments includes a maintenance pool and spray pipes. The maintenance pool contains a platform for placing the TBM segments. A filter screen is installed at an angle within the maintenance pool. The platform extends vertically through the filter screen. A sludge collection trough with its opening facing the side of the maintenance pool is located on one side, connecting to the lower end of the filter screen. Two spray pipes are symmetrically installed within the maintenance pool, distributed on both sides of the platform. Spray heads are evenly distributed on the spray pipes. A circulating water supply mechanism is provided on one side of the maintenance pool to circulate water from the maintenance pool to the spray pipes.

[0007] Therefore, using a filter screen can filter out dirt and waste, causing the dirt and waste to remain above the filter screen while the water flows below the filter screen for recycling. This effectively prevents dirt and waste from clogging the spray pipes. The dirt and waste remaining on the filter screen will flow down into the collection tank. After spraying, tools can be used to sweep the dirt and waste from the filter screen into the collection tank for collection and later centralized treatment.

[0008] Furthermore, an L-shaped plate is fixed inside the curing tank on the side where the filter screen is lower. The L-shaped plate and the inner wall of the curing tank form a placement space, and the sludge collection tank is placed in the placement space from top to bottom.

[0009] Furthermore, a lifting rod is fixed at the top of the sludge collection trough, extending vertically upwards to the top of the maintenance tank.

[0010] Furthermore, vertically extending slide rails are fixed on the inner walls of both sides of the curing pool, near the side with the lower height of the filter screen, and baffles that can slide up and down are installed on the two slide rails.

[0011] Furthermore, a vertically extending support is fixed to the top of the baffle, and a horizontally penetrating locking hole is provided on the support. A fixing block is fixed to the top of the curing pool, and a horizontally extending locking pin is slidably inserted into the fixing block. The locking pin and the locking hole are engaged in a corresponding locking fit.

[0012] Furthermore, the circulating water supply mechanism includes a mounting base, a water pump, connecting pipe A, connecting pipe B, and a tee connector. The water pump is installed on the side of the curing tank via the mounting base. The input part of connecting pipe A is connected to the inside of the curing tank via connecting pipe A. One end of connecting pipe B is connected to two spray water pipes via a tee connector, and the other end is connected to the output part of the water pump.

[0013] Furthermore, the placement platform extends along the length of the maintenance pool.

[0014] Furthermore, several pairs of support bars are arranged in an array along the length of the placement platform to support the vertical placement of the tunnel segments.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] This invention utilizes a filter screen to filter out dirt and waste, allowing the dirt and waste to remain above the filter screen while the water flows below the filter screen for recycling, effectively preventing dirt and waste from clogging the spray pipes.

[0017] In this invention, the dirt and waste remaining on the filter screen will flow down the filter screen into the collection tank. After spraying, the dirt and waste on the filter screen can be swept into the collection tank using a tool, so that the dirt and waste can be collected for centralized treatment later.

[0018] This invention adds a slide rail to the inner wall of the curing tank and slides a baffle on the slide rail. Before the sludge collection tank is removed from the placement space, the baffle is slid down and adjusted until the bottom of the baffle contacts the surface of the filter screen, which can block the sludge and waste and prevent the sludge and waste from falling into the placement space.

[0025] Please see Figures 1-5 This utility model provides a maintenance device for repairing defects in tunnel lining segments. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0027] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0028] This maintenance equipment includes a maintenance pool 1 and spray pipes 3. The maintenance pool 1 is equipped with a placement platform 11 for placing tunnel segments. A filter screen 2 is installed at an angle in the maintenance pool 1. The placement platform 11 extends vertically through the filter screen 2. A sludge collection trough 5 with its opening facing the direction is arranged on one side of the maintenance pool 1. The sludge collection trough 5 is connected to the lower end of the filter screen 2. Two spray pipes 3 are symmetrically installed in the maintenance pool 1 and distributed on both sides of the placement platform 11. Spray heads 31 are evenly distributed on the spray pipes 3. A circulating water supply mechanism 4 is provided on one side of the maintenance pool 1 to circulate the water in the maintenance pool 1 to the spray pipes 3.

[0029] The tunnel segment is placed on the placement platform 11. The water supply mechanism 4 draws the spray water from the curing pool 1 into the spray water pipe 3 and sprays it out through the spray water pipe 3. The spray water pipes 3 arranged on both sides of the placement platform 11 can spray the tunnel segment on both sides to achieve spray curing after the tunnel segment defect is repaired, so as to improve the molding quality of the repair material.

[0030] The spray water carries the dirt and waste attached to the tunnel segments. When it flows onto the filter screen 2, the dirt and waste are filtered out, so that the dirt and waste remain above the filter screen 2, while the water flows below the filter screen 2 for recycling, effectively preventing dirt and waste from clogging the spray pipes.

[0031] The dirt and waste remaining on the filter screen 2 will flow down the filter screen 2 into the collection tank 5. After the spraying is finished, use a tool to sweep the dirt and waste on the filter screen 2 into the collection tank 5 to collect the dirt and waste for later centralized treatment.

[0032] Specifically, an L-shaped plate 51 is fixed inside the curing tank 1 on the side where the filter screen 2 is lower. The L-shaped plate 51 and the inner wall of the curing tank 1 form a placement space 52. The sludge collection tank 5 is placed in the placement space 52 from top to bottom. The sludge collection tank 5 can be lifted up and taken out from the L-shaped plate 51, which makes it easy to dump the sludge and waste in the sludge collection tank 5.

[0033] In addition, it is worth noting that micropores are evenly distributed on the sludge collection tank 5 and the L-shaped plate 51. The micropores are only for water to flow through, so that some water can flow out through the micropores after entering the sludge collection tank 5, thus avoiding the accumulation of water in the sludge collection tank 5 and affecting the collection of sewage and waste. Furthermore, sewage and waste cannot pass through the micropores and can only remain in the sludge collection tank 5.

[0034] Specifically, a lifting rod 53 is fixed at the top of the sludge collection tank 5, extending vertically upward to the top of the maintenance tank 1. The sludge collection tank 5 can be easily picked up and put down by pinching the lifting rod 53.

[0035] When the collection tank 5 is removed to empty the waste and debris, the placement space 52 becomes empty. The waste and debris remaining on the filter screen 2 will roll into the placement space 52 and are difficult to clean. Over time, this leads to excessive accumulation of waste and debris in the placement space 52, making it difficult to properly place the collection tank 5 within the space, thus affecting the collection of waste and debris. To solve this problem, the present invention proposes the following improvements:

[0036] Vertically extending slide rails 6 are fixed on the inner walls of both sides of the curing pool 1, near the side with the lower height of the filter screen 2. Baffles 7 that can slide up and down are installed on the two slide rails 6.

[0037] By installing a slide rail 6 on the inner wall of the maintenance tank 1 and sliding a baffle 7 on the slide rail 6, before removing the sludge collection tank 5 from the placement space 52, the baffle 7 can be adjusted downwards until the bottom of the baffle 7 contacts the upper surface of the filter screen 2, which can block the sludge and waste and prevent the sludge and waste from falling into the placement space 52. When the sludge collection tank 5 is reinstalled into the placement space 52, the baffle 7 can be adjusted upwards to collect the sludge and waste normally.

[0038] Specifically, a vertically extending support 71 is fixed to the top of the baffle 7, and a horizontally penetrating locking hole 72 is provided on the support 71. A fixing block 73 is fixed to the top of the curing pool 1, and a horizontally extending locking pin 74 is slidably inserted into the fixing block 73. The locking pin 74 and the locking hole 72 are correspondingly engaged. After the baffle 7 is adjusted upward until the locking hole 72 and the locking pin 74 are aligned, the locking pin 74 is inserted into the locking hole 72 to achieve locking. This can position the baffle 7 and prevent the baffle 7 from falling downward due to gravity.

[0039] Specifically, the circulating water supply mechanism 4 includes a mounting base 41, a water pump 42, a connecting pipe A43, a connecting pipe B44, and a tee connector 45. The water pump 42 is installed on the side of the curing tank 1 through the mounting base 41. The input part of the connecting pipe A43 is connected to the inside of the curing tank 1 through the connecting pipe A43. One end of the connecting pipe B44 is connected to the two spray water pipes 3 through the tee connector 45, and the other end is connected to the output part of the water pump 42. When the water pump 42 is working, the water in the curing tank 1 is pumped into the connecting pipe B44 through the connecting pipe A43, and the water is diverted into the two spray water pipes 3 through the tee connector 45, so as to realize the recycling of water.

[0040] Specifically, the placement platform 11 extends along the length of the curing pool 1, and the spray head 31 on the spray pipe 3 also extends along the length of the curing pool 1. Multiple shield tunnel segments are arranged in a straight line on the placement platform 11, and spray curing operations can be carried out simultaneously. Several pairs of support bars 12 are arranged in an array along the length of the top of the placement platform 11 to support the shield tunnel segments to be placed vertically. The shield tunnel segments are placed between two support bars 12, and the two support bars 12 can firmly support the shield tunnel segments to ensure the stability of the shield tunnel segments during spray curing.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
