Description

Technical Field

[0001] The invention relates to the technical field of metallurgical construction, and in particular to a low-position wall-penetrating casing anti-leakage device for a water pool and a construction method. Background Art

[0002] In the field of metallurgical construction, the side walls of turbid water pools, clean water pools, sludge pools, fire water pools and other public auxiliary water systems have reserved casings for various medium pipelines to pass through. There are many pipes between the pump room and the water pool. The casings are basically located at the bottom of the side walls of the water pool, and some are even close to the bottom plate. The diameter is large, even reaching more than 1000mm. Usually, the concrete of the water pool is poured in two times. The first time is to pour the bottom plate, and the second time is to pour the side wall and top plate. During the first pouring, a steel plate waterstop is set according to the standard construction joint, and it is left at a height of 300-500mm on the side wall above the bottom plate.

[0003] When a larger diameter waterproof casing is buried at a low position, the casing will disconnect the steel plate waterstop strip of the construction joint. When the side wall concrete is poured below the casing, due to space limitations such as casing obstruction and steel-dense areas, the concrete below the casing is often not filled densely. In addition, the concrete itself shrinks and has surface slurry. The secondary joint cannot be completely roughened due to space limitations. Therefore, water seepage and leakage often occur in the contact area between the casing and the concrete and the disconnection area between the casing and the construction joint. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention provides a low-position wall-penetrating casing anti-leakage device for a water pool and a construction method.

[0010] By adopting the above technical solution, the water flow path is extended and a better water blocking effect is achieved.

[0011] Optionally, the height of the reinforced waterstop steel plate exceeds the upper and lower sides of the construction joint by 200-300 mm, and the length exceeds the distance of the casing wing ring by 300-500 mm.

[0012] By adopting the above technical solution, the length of the reinforced water-stop steel plate is appropriate, which facilitates the welding and fixing of the reinforced water-stop steel plate and the fixed bracket.

[0025] Reference Figure 1 , Figure 2 and Figure 3, a casing wing ring 6 is welded on the peripheral wall of the steel casing 4, and the casing wing ring 6 is coaxially arranged with the steel casing 4. A reinforced water-stopping steel plate 7 is welded between two adjacent steel plate water-stopping strips 5, and an arc-shaped groove adapted to the steel casing 4 is arranged on the top of the reinforced water-stopping steel plate 7. The height of the reinforced water-stopping steel plate 7 exceeds the upper and lower sides of the construction joint 3 by 200-300mm, and the length exceeds the distance of the casing wing ring 6 by 300-500mm. The steel casing 4 is perpendicular to the reinforced water-stopping steel plate 7 and is laid on the reinforced water-stopping steel plate 7. The reinforced water-stopping steel plate 7 is welded and fixed to the casing wing ring 6, and the upper and lower edges of the reinforced water-stopping steel plate 7 are bent in the water-facing direction to form a folded edge.

[0026] Reference Figure 1 A fixing bracket 8 is vertically embedded in the pool bottom plate 1 and the pool side wall 2. The fixing bracket 8 can be made of angle steel or channel steel. Two fixing brackets 8 are provided and located at both ends of the reinforced water-stopping steel plate 7. The fixing bracket 8 is welded and fixed to the reinforced water-stopping steel plate 7. A wall reinforcement 9 is provided in the pool side wall 2. A plurality of obliquely arranged reinforcement ribs 10 are tied and fixed between the wall reinforcement 9 and the casing wing ring 6 to enhance the stability of the steel casing 4 and the structural strength of the area.

[0027] Reference Figure 4 The anti-leakage construction method of the low-position wall sleeve of the pool according to the embodiment of the present invention comprises the following steps: S1. Fix the fixed bracket 8, specifically including: vertically arranging the fixed bracket 8 on both sides of the steel casing 4, welding and fixing the bottom of the fixed bracket 8 to the cushion layer and the lower steel mesh of the bottom plate, and welding and fixing the middle part of the fixed bracket 8 to the upper steel mesh of the bottom plate.

[0028] S2. Assemble the welded steel casing 4, casing wing ring 6 and reinforced waterstop steel plate 7, specifically including: according to the size of the steel casing 4, sleeve the welded casing wing ring 6 on the steel casing 4, then use a steel plate with the same thickness as the steel plate waterstop 5 to cut an arc-shaped groove and fully weld it to the casing wing ring 6, and bend and fold the upper and lower edges of the reinforced waterstop steel plate 7 to make it consistent with the steel plate waterstop 5, with the folded edge facing the water facing surface when buried.

The distance between the insertion points of the vibrating rod is no more than 400mm, and when vibrating the upper layer of concrete, the vibrating rod is inserted 50mm into the lower layer of concrete to eliminate the joint between the two layers of concrete. The vibration time is based on the concrete surface no longer sinking significantly, no bubbles appearing, and mortar coming out of the surface.

[0031] When pouring to the steel casing 4, due to the obstruction of the steel casing 4, the concrete cannot be poured directly to the bottom area of ​​the steel casing 4, and can only flow to the bottom of the steel casing 4 from the side by its own fluidity. The vibrating rod is inserted obliquely to vibrate for better compaction. With the vibration of the vibrating rods on both sides, the concrete fills the bottom of the steel casing 4. The construction joint 3 is guaranteed to be left in the middle of the steel plate water stop 5, and the joint surface is ensured to be roughened and cleaned.

[0032] The construction method is simple and easy to operate, and the anti-leakage device can be made from local materials, which is not only convenient but also green and environmentally friendly. The reinforced water-stop steel plate 7 is welded with the casing wing ring 6 and the steel plate water-stop belt 5 to form a waterproof module unit, which effectively changes and extends the blocking path of water seepage and reduces the risk of water seepage; at the same time, it is convenient for construction personnel to install and construct on site, and it is convenient for inspection after construction, which effectively ensures the construction quality.
