[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] Please see attached Figure 1 and attached Figure 2 A cleaning structure for a drain outlet in a composite wall, the cleaning structure is used in the composite wall, the composite wall includes an underground continuous wall 1 located on the outside and a brick wall 2 located on the inside, a drainage ditch is formed between the underground continuous wall 1, the brick wall 2 and the bottom plate 7 of the layer structure, and a drain outlet 3 penetrating the bottom plate 7 is formed at the bottom of the drainage ditch.
[0023] In the basement structure, a downspout 3 is provided on each floor slab 7 located in the drainage ditch except the bottom floor, so that the seepage water can be discharged layer by layer to the bottom floor slab through the downspout 3, and then collected to the sump through the drainage ditch on the bottom floor slab. The downspout 3 of the composite wall and its various layers are constructed by conventional technology, which will not be described here.
[0024] Please see attached Figure 1 and attached Figure 2 The cleaning structure includes an inspection port 4, a dredging tool hook 5 and a dredging tool 6; the inspection port 4 is arranged on the brick wall 2, so that the drainage ditch can be connected with the inner space of the brick wall 2 through the inspection port 4, and the inspection port 4 is arranged on the side and above the downspout 3; the dredging tool 6 is arranged in the drainage ditch, and is hung on the outer wall of the brick wall 2 (the side of the brick wall 2 close to the underground continuous wall 1 is the outside, and the side of the brick wall 2 away from the underground continuous wall 1 is the inside) through the dredging tool hook 5, so that the dredging tool 6 is located between the inspection port 4 and the downspout 3.
[0025] The provision of the inspection opening 4 facilitates the construction personnel to inspect the blocked drain outlet 3. In order to take into account both the inspection needs and the structural strength of the brick wall 2, the inspection opening 4 is relatively small in overall length, and the interior of the gutter is relatively narrow. Conventional inspection and dredging tools cannot be placed into the gutter through the inspection opening 4, and it is also difficult to perform dredging and cleaning operations in the narrow gutter space. Therefore, during the construction of the composite wall, the dredging tool 6 is hung in the gutter in advance through the dredging tool hook 5, thereby avoiding the problem of being unable to place conventional inspection and dredging tools for dredging.
[0026] When in use, it is only necessary to open the inspection port 4, and the construction worker's hand can be inserted into the drain ditch through the inspection port 4 to take out the dredging tool 6 to inspect the blocked drain outlet 3. After the inspection is completed, the dredging tool 6 is hung back on the dredging tool hook 5, and the inspection port 4 is closed, which can ensure the convenience and timeliness of the inspection.
[0027] Please see attached Figure 3 The dredging tool 6 includes a dredging rod 601 and a hook 602, and the hook 602 is formed at one end of the dredging rod 601; the hook 602 is matched and hung on the dredging tool hook 5, so that the dredging rod 601 is hung between the inspection port 4 and the drain port 3.
[0028] The hook 602 can be inverted U-shaped, so that it can be hung on the dredging tool hook 5 and is not easy to fall off. The dredging rod 601 can be selected according to the diameter of the water outlet 3 and the possible blockage, so that the water outlet 3 can be effectively dredged and cleaned by the dredging rod 601.
[0029] The dredging rod 601 is hung between the inspection port 4 and the water outlet 3. When the construction personnel put their hands into the drainage ditch, they can grab the dredging rod 601, which is convenient for use.
[0030] Please see attached Figure 1 and attached Figure 2 The dredging tool hook 5 is located above the top of the inspection port 4, so that the dredging rod 601 is located outside the inspection port 4 when it is hung below the dredging tool hook 5.
[0031] The dredging tool hook 5 is located above the inspection port 4. After the dredging rod 601 is hung, it passes downward through the inspection port 4. When the construction worker puts his hand into the drainage ditch, he can grab the dredging rod 601, which is convenient for operation.
[0032] Please see attached Figure 1 One end of the dredging tool hook 5 is embedded in the brick wall 2, and the other end of the dredging tool hook 5 protrudes upward to form a limiting portion 501, so that the hook 602 is located between the limiting portion 501 and the brick wall 2.
[0033] By setting the limiting part 501 , the lateral movement of the hook 602 can be limited together with the brick wall 2 , thereby preventing the dredging tool 6 from falling off the dredging tool hook 5 .
[0034] The diameter of the dredging rod 601 is smaller than the diameter of the drain outlet 3 , and the length of the dredging rod 601 is greater than the depth of the drain outlet 3 , so as to ensure that the dredging rod 601 can be stably held and the drain outlet 3 can be effectively dredged.
[0035] The dredging rod 601 and the hook 602 are an integrated structure with high structural strength, not easy to deform and damage, long service life, and can be made of steel bars in one piece.
[0036] Please see attached Figure 1 To Attachment Figure 3 The construction method and use method of the utility model are:
[0037] Conventional construction methods are used to construct the underground continuous wall 1 and the brick wall 2 to form a composite wall with a drainage ditch, and a water outlet 3 is reserved on the bottom plate 7 at the bottom of the drainage ditch. This structure is a conventional structure of the existing composite wall, and its construction process and construction technology will not be repeated here.
[0038] During the construction of the brick wall 2, a hole is reserved above and beside the drain outlet 3 for installing the inspection opening 4. Preferably, the inspection opening 4 can be an inspection door that can be opened and closed by hinges, which is convenient for opening for maintenance. The size of the inspection opening 4 is suitable for the construction workers to safely insert their hands without affecting the structural strength of the brick wall 2.
[0039] At the same time, during the construction of the brick wall 2, a clearing tool hook 5 is pre-embedded on the side of the brick wall 2 facing the underground continuous wall 1. The clearing tool hook 5 and its limiting part 501 can be made of a J-shaped hook body made of bent steel bars, which can be horizontally installed above the inspection opening 4 on the brick wall 2.
[0040] A steel bar with a diameter of 12 mm is used as the dredging rod 601. One end of the dredging rod 601 is bent to form a hook 602 with an inverted U-shaped structure. The dredging rod 601 is hung on the inner side of the brick wall 2 through the hook 602 via the dredging tool hook 5 and its limiting part 501.
[0041] When unclogging the drain outlet 3, the inspection port 4 is opened, and the construction worker's hand reaches into the drain ditch through the inspection port 4. Since the unclogging rod 601 is located outside the inspection port 4, the hand can grab the unclogging rod 601 when reaching in. The unclogging rod 601 is slightly lifted up to make the hook 602 detach from the unclogging tool hook 5, and the unclogging tool can be removed. Since the unclogging rod 601 is located beside the drain outlet 3, the unclogging rod 601 can be easily inserted into the drain outlet 3, thereby unclogging and cleaning the drain outlet 3.
[0042] After the dredging is completed, the dredging rod 601 is still hung between the water outlet 3 and the inspection port 4 through the hook 602 via the dredging tool hook 5, so as to facilitate the next use, and the inspection port 4 can be closed. The entire dredging process only requires the construction personnel to turn their wrists, and can be carried out in a narrow drainage ditch space.
[0043] The dredging method of the drain outlet 3 of each layer structure is the same, and can be dredged layer by layer from top to bottom, which will not be described in detail here.
[0044] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
