Abstract
Description
Technical Field
[0001] The invention relates to the technical field of water reservoir engineering, and in particular to a pipe penetrating a pool wall structure and a construction method. Background Art
[0002] At present, in municipal engineering projects such as sewage treatment plants, water purification plants, pumping stations, as well as industrial and civil construction, most of them are inseparable from various pool structures. The inlet and outlet pipes passing through the reinforced concrete pool wall is a common problem in pool construction. When the pipe passes through the reinforced concrete pool wall, there is a joint surface between the pipe and the pool wall. The way of passing through the joint surface, the construction process and the anti-leakage effect of the pool wall directly affect the normal use of the entire pool.
[0003] The traditional pipe penetration device mainly includes waterproof casing. According to the standard drawing of "Waterproof Casing" (02S404) issued by the Ministry of Construction (such as Figure 1As shown in the figure, it is mainly composed of a rigid waterproof casing 5 with a water stop ring welded in the middle part of the pool wall, a pool wall pipe 6 with a retaining ring welded in the middle part, and asbestos cement and oil hemp filled in the gap between the first two. Its process principle and installation method are: according to the requirements of the construction drawings, select a finished rigid waterproof casing that matches the diameter of the pool wall pipe, and bury the rigid waterproof casing with a 50-60mm wide water stop ring welded in the middle on the pool wall according to the design elevation requirements; weld a 10mm wide retaining ring on the outer edge of the pool wall pipe, and after the pool wall concrete construction is completed, pass the pool wall pipe welded with the retaining ring through the rigid waterproof casing, and fill the gap between the pool wall pipe and the rigid waterproof casing with asbestos cement and oil hemp. However, the existing waterproof casing construction process has the following main disadvantages: 1) The installation position is inaccurate. It is mainly reflected in two aspects: ① The construction of the pool wall easily causes the displacement of the waterproof sleeve, resulting in the center elevation of the pipe through the pool wall not being consistent with the original design elevation, and there is a large deviation between the pipe through the pool wall and the original design position; this defect is particularly serious when the same pipe needs to be installed on the same axis for multiple consecutive passes through the pool wall. ② After the completion of the civil construction of the pool body, the design of the elevation of the pipe through the pool wall or the deviation of the setting of the center elevation of the pipe during the construction of the pool wall waterproof sleeve makes it impossible to install the pipe through the pool wall, the waterproof sleeve needs to be chiseled out and reworked, and the probability of water leakage in the later waterproof sleeve is greatly increased. 2) Waterproof sleeve leakage caused by filling material 7. It is mainly reflected in two aspects: ① The periodic expansion and contraction caused by changes in ambient temperature or internal fluid pressure causes the filling material 7 between the pipe through the pool wall and the waterproof sleeve to become loose, aged, and produce gaps, resulting in water leakage. ② Due to the installation error, the pipe through the pool wall and the waterproof sleeve are eccentric, and the filling space between the two is uneven. The oil hemp filling construction process cannot guarantee that the gap between the pipe through the pool wall and the waterproof sleeve is completely filled, resulting in water leakage. 3) The filling material is not environmentally friendly. As asbestos fiber can cause diseases such as asbestosis and pleural mesothelioma, although the country has not yet banned the use of asbestos cement as a filling material, it is not conducive to the health protection of construction workers and the development trend of environmentally friendly materials. 4) The installation accuracy is high and the construction is difficult. The waterproof casing is only about 30mm larger than the outer diameter of the pipe through the pool wall. In this case, the pipe through the pool wall is passed through the waterproof casing and the axis of the pipe is ensured to be centered and horizontal. The high installation accuracy greatly increases the construction difficulty and reduces the construction speed.
[0004] In order to solve the disadvantages of using waterproof sleeves, those skilled in the art have developed a pipe-through-pool-wall device (such as CN 206889866U) for preventing leakage. Figure 2As shown), it includes a steel plate 1, which is arranged on the outer diameter of the pipe 6 penetrating the pool wall, and an annular water stop plate is fixedly arranged on the steel plate 1. Its main construction process is: the steel plate with a water stop ring welded on the outer edge is vertically buried in the middle part of the thickness of the pool wall to be penetrated, and wooden formworks 8 are supported on both sides; after the concrete is poured, the wooden formworks 8 are removed; a circular hole is cut on the steel plate with a flame, and the pipe penetrating the pool wall is passed through the circular hole, and the contact between the pipe and the steel plate is firmly welded, and then the two sides of the steel plate are grouted with concrete and smoothed. However, this construction process has the following main disadvantages: 1) High installation accuracy requirements and great construction difficulty. The steel plate opening is only slightly larger than the outer diameter of the pipe. In this case, the pipe penetrating the pool wall is passed through the steel plate with the opening, and the axis of the pipe is ensured to be centered and horizontal. The high installation accuracy greatly increases the construction difficulty and reduces the construction speed. 2) The construction of the pipe penetrating the pool wall is prone to damage the perforated steel plate and the contact welds between the two. The gap between the steel plate opening and the pipe through the pool wall should not be too large, otherwise it will be detrimental to ensuring the welding quality. However, a smaller gap increases the difficulty of the pipe through the pool wall. A slight tilt during the construction of the pipe through the pool wall will squeeze and damage the steel plate, and will also wear off the anti-corrosion coating on the outside of the pipe wall. At the same time, the pipe through the pool wall and the steel plate are only fixed by two inner and outer welds in this process, and the fixing ability of the two is not strong. The vibration of the pipe through the pool wall will affect or even damage the two inner and outer welds, resulting in water leakage. Summary of the invention

[0035] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0036] like Figure 3 As shown, the pipe penetrating pool wall structure of this embodiment includes a pool wall body 100 and a steel plate 1 buried in the pool wall body 100 on all sides. The steel plate 1 has an opening 2. A first pipe 3 is connected to one side of the steel plate 1, and a second pipe 4 is connected to the other side of the steel plate 1. The ends of the first pipe 3 and the second pipe 4 are abutted against the side surfaces of the steel plate 1 and are sealed and connected by welding. The opening 2 connects the first pipe 3 and the second pipe 4. In the pipe-through-pool-wall structure, the steel plate 1 is buried in the pool wall body 100 on all sides, the ends of the first pipe 3 and the second pipe 4 are both abutted against the side of the steel plate 1 and are sealed and connected by welding, and the first pipe 3 and the second pipe 4 are connected through the opening 2 of the steel plate 1, and a good seal is formed between the steel plate 1 and the pool wall body 100, and between the first pipe 3 and the second pipe 4 and the steel plate 1, and the sealing and water-proof performance are good, the reliability is high, and the service life is long; and, since the ends of the first pipe 3 and the second pipe 4 are both abutted against the side of the steel plate 1 and are sealed and connected by welding, during construction, the pipes do not need to pass through the opening 2. On the premise of ensuring the installation accuracy, the construction difficulty can be reduced, and the problem of squeezing and damaging the steel plate 1 and wearing off the anti-corrosion coating on the pipe wall during the pipe passing through the opening 2 can also be avoided.
[0037] Preferably, the aperture of the opening 2, the inner diameter of the first pipe 3 and the inner diameter of the second pipe 4 are equal, and the hole wall of the opening 2, the inner wall of the first pipe 3 and the inner wall of the second pipe 4 are flush. In this structure, the hole wall of the opening 2, the inner wall of the first pipe 3 and the inner wall of the second pipe 4 are flush, which can make the water flow smoothly when passing through the pipe-through-pool-wall structure composed of the first pipe 3, the opening 2 and the second pipe 4, and achieve the same technical effect as the prior art of a pipe-through-pool-wall passing through the opening.
[0038] Preferably, both the inner and outer sides of the first pipe 3 and the second pipe 4 are sealed and connected to the steel plate 1 through annular welds. By welding the inner and outer walls of the first pipe 3 to the steel plate 1 to form two inner and outer annular welds, the connection strength between the first pipe 3 and the steel plate 1 is enhanced, the influence of pipeline vibration on the annular weld is greatly reduced, and the anti-leakage performance is better; the second pipe 4 is the same as the first pipe 3, which will not be repeated here. In this embodiment, the width of the annular weld is preferably 6 mm, and the annular weld is treated with anti-corrosion to extend the service life.
[0039] Preferably, the wall thickness of the first pipe 3 and the second pipe 4 are equal, and the thickness of the steel plate 1 is twice the wall thickness of the first pipe 3 and the second pipe 4. The use of a steel plate twice the wall thickness of the first pipe 3 and the second pipe 4 can enhance the overall strength of the pipe-through-pool wall structure, and prevent external forces and pipe vibrations from damaging the steel plate 1, causing failure of the pipe-through-pool wall structure.
[0040] Preferably, the outer periphery of the steel plate 1 is provided with an annular bent portion 11 bent to one side. In this embodiment, the annular bent portion 11 is bent to the water-facing side to enhance the water-stopping effect of the steel plate 1.
[0041] Preferably, the angle α between the annular bend 11 and the side of the steel plate 1 is 135°-165°. In this embodiment, the angle α between the annular bend 11 and the side of the steel plate 1 is preferably 150°, which can ensure that the steel plate 1 has a certain rigidity during construction, is easy to form and process, is conducive to rapid construction, and enhances the water-stopping effect.
[0042] Preferably, the length of the annular bending portion 11 is 50 mm to 70 mm. In this embodiment, the length of the annular bending portion 11 is preferably 60 mm, which can enhance the engagement and fixing effect between the steel plate 1 and the pool wall body 100 and help enhance the water stopping effect.
[0043] Preferably, the distance between the outer edge of the annular bend 11 and the outer wall of the first pipe 3 and the second pipe 4 is not less than the outer diameter of the first pipe 3 and the second pipe 4, and is not less than 200 mm. After the steel plate 1 is embedded, the structure leaves space for position adjustment when the opening 2 is opened, so that the pipe-through-pool wall structure has a certain adaptability to small changes in the center elevation of the pipe.
