Technical Field
[0001] The utility model relates to the technical field of waterproof engineering, and more specifically, the utility model relates to a drainage device for leakage of reinforced concrete walls. Background Technique
[0002] At present, the structural forms of buildings or structures are mostly reinforced concrete structures. According to people's needs for buildings, many buildings are provided with basements, and their peripheral structures are reinforced concrete structures. Considering that concrete works with cracks, the inner surface of the reinforced concrete exterior wall in a damp underground environment will show leakage over time and under the influence of external vibration loads, etc., affecting the appearance and structural life.
[0003] The commonly used waterproof method for treating reinforced concrete walls is the grouting method, that is, pressurizing the grouting equipment and injecting the waterproof grout into the concrete through a needle tube. The waterproof grout expands when it meets water and fills the internal gaps of the concrete, so as to achieve the waterproof effect.
[0004] According to actual engineering experience, grouting multiple times in some leakage areas of the wall still cannot stop the leakage, indicating that the grouting method cannot completely solve the wall leakage problem. Content of the Utility Model

The technical problem to be solved by the present invention is: the treatment method for leakage of the reinforced concrete exterior wall of the basement is the grouting method, and there is still leakage after multiple groutings, and the wall leakage cannot be solved after multiple groutings.
[0006] To achieve the above object, the drainage device for leakage of reinforced concrete walls of the utility model includes a vertical drainage pipe arranged outside the reinforced concrete wall, a horizontal drainage pipe with a part inside the wall and a part outside the wall, and a horizontal diversion pipe buried at the leakage part of the wall;
[0007] The lower part of the vertical drainage pipe is connected to a drainage channel, and the vertical drainage pipe is connected through a right-angle adapter. The right-angle adapter should be matched with the vertical drainage pipe, and the horizontal diversion pipe is connected to the horizontal drainage pipe through a tee joint;

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] As Figure 1 shown, the drainage device for leakage of reinforced concrete walls of the present utility model includes a vertical drainage pipe 1 arranged outside the reinforced concrete wall, a horizontal drainage pipe 3 with a part inside the wall and a part outside the wall, and a horizontal diversion pipe 5 buried at the wall leakage point 6.
[0028] A right-angle adapter 2 connects the vertical drainage pipe 1 and the horizontal drainage pipe 3, and a tee joint 4 connects the horizontal drainage pipe 3 and two diversion pipes 5; after connection, the two diversion pipes 5 are perpendicular to the horizontal drainage pipe 3; a cut seam 51 is made on the diversion pipe 5 in advance with a cutting machine, and the depth of the cut seam 51 does not exceed half of the pipe diameter.
[0029] Both ends of the horizontal diversion pipe 5 are blocked with thin sponge covers to prevent the waterproof mortar 7 from entering the horizontal diversion pipe 5 and affecting the diversion effect.
[0030] As Figure 2 shown, the wall leakage point 6 should be determined in advance according to the size of the leakage area of the reinforced concrete wall, and the excavation depth should be appropriate to accommodate the diversion pipe. The specific depth, width and height shall be confirmed according to actual needs.
[0031] The vertical drainage pipe 1, the horizontal drainage pipe 3 and the horizontal diversion pipe 5 have their cutting lengths determined according to the relevant data of the confirmed wall leakage point 6. The right-angle adapter 2 and the tee joint 4 are supporting components for the vertical drainage pipe 1, the horizontal drainage pipe 3 and the horizontal diversion pipe 5, and can be freely selected as long as there is no leakage after connection. Wrap a layer of permeable gauze around the horizontal diversion pipe 5.
[0032] As Figure 3 shown, keep the wall leakage point 6 clean without sundries such as concrete fragments. Before installing the drainage device, first lay a layer of waterproof mortar layer with an inward slope at the bottom of the space at the wall leakage point, and then press the drainage device into this mortar layer to ensure that the waterproof mortar under the horizontal diversion pipe is full. Subsequently, seal the remaining space part of the wall leakage point 6.
[0033] There is a certain distance between the vertical drainage pipe 1 and the wall, and it can be directly fixed to the wall with the supporting pipe clamp.
[0034] The installation method of the drainage device of the present utility model includes the following steps:
[0035] Step 1: Observe the characteristics and scope of the wall leakage and find the leakage point. Excavate near the leakage point, and the excavation scope is the area range of the leakage point. During the excavation process, pay attention to the water flow direction to better confirm the excavation scope. This step should be flexibly changed according to the actual situation, and its purpose is to better divert the seepage water into the horizontal diversion pipe 5.
[0036] Step 2: Measure the lengths of the vertical drainage pipe 1, the horizontal drainage pipe 3 and the horizontal diversion pipe 5 according to the size of the excavated hole, and select the specifications and models of the pipes.
[0037] Step 3: Select and match the right-angle adapter for connecting the vertical drainage pipe 1 and the horizontal drainage pipe 3, and select and match the tee joint 4 for connecting the horizontal drainage pipe 3 and the horizontal diversion pipe 5.
[0038] Step 4: Connect the vertical drainage pipe 1 and the horizontal drainage pipe 3 through the right-angle adapter 2, and connect the horizontal drainage pipe 3 and the horizontal diversion pipe 5 through the tee joint 4; the connection should be tight and there should be no leakage at the joints.
[0039] Step 5: Use a cutting machine to cut several slits 51 on the horizontal diversion pipe 5, and the depth of the slits does not exceed half of the pipe diameter; in addition, cut a slit 51 in the middle of the tee joint.
[0040] Step 6: Seal both ends of the horizontal diversion pipe 5 with a thin sponge cover, and wrap a circle of permeable gauze around the horizontal diversion pipe. The purpose is to prevent the waterproof mortar from entering the horizontal diversion pipe 5 through the cut slits.
[0041] Step 7: Clean the wall leakage point 6 thoroughly without any sundries such as concrete fragments. Lay a layer of waterproof mortar layer with an inward slope at the bottom of the space chiseled at the wall leakage point, and then press the drainage device into this mortar layer to ensure that the waterproof mortar under the horizontal drainage pipe is full.
[0042] Step 8: Seal the remaining space part of the wall leakage point 6.
[0043] Step 9: There is a certain distance between the vertical drainage pipe 1 and the wall, and it can be directly fixed to the wall with the matching pipe clamp.
