Description
Technical Field
[0001] The utility model relates to the technical field of sedimentation tanks, in particular to a secondary drainage structure of a sedimentation tank. Background Art
[0002] At present, most bathrooms in residential buildings adopt a sunken bathroom design. Secondary drainage means that in addition to the floor drain outlet on the surface of the bathroom, a second hidden drain outlet is set at the bottom of the caisson. When the first waterproofing leaks, the accumulated water in the caisson can be discharged in time to prevent the accumulated water from soaking for a long time, corroding the waterproof layer, and causing leakage.
[0003] The existing secondary drainage of sedimentation tanks generally involves first installing the secondary drainage pipe and then laying a backfill layer to bury the sewage pipe and the secondary drainage pipe. A diversion waterproof layer is made on the top of the secondary drainage pipe, and finally a backfill layer is laid to complete the base layer. When laying the second backfill layer, backfill materials or other decoration materials will fall to the pipe mouth. For example, gravel, sand or cement will fall into the pipe mouth of the secondary drainage pipe and cause blockage, thereby affecting its drainage effect. Therefore, we designed a secondary drainage structure for the sedimentation tank. Utility Model Content
[0004] The utility model aims to provide a secondary drainage structure for a sedimentation tank. The secondary drainage structure of the sedimentation tank seals the secondary drainage pipe without affecting the normal decoration of the sedimentation tank, thereby preventing the pipe mouth from being blocked by decoration materials. After backfilling is completed, the drainage gap at the pipe mouth is opened to ensure normal drainage, thereby solving the problems raised in the background technology.
[0005] To achieve the above objectives, the utility model is achieved through the following technical solutions: a secondary drainage structure of a sedimentation tank includes a sedimentation tank, the inner bottom wall of the sedimentation tank is fixedly connected to a sewage pipe through a supporting block, and the sewage pipe is fixedly connected to a secondary drainage pipe at the bottom of the sedimentation tank. A ceramsite backfill layer 1 is laid on the bottom of the sedimentation tank, a cement mortar leveling layer is laid on the top of the ceramsite backfill layer 1, a ceramsite backfill layer 2 is laid on the top of the cement mortar leveling layer, and floor tiles are laid on the top of the ceramsite backfill layer 2. The top of the secondary drainage pipe is fixedly connected to a protective pipe, a drainage notch is opened on the outer side of the protective pipe, a movable plate is movably connected to the inner wall of the protective pipe, the lower surface of the movable plate is fixedly connected to a connecting rod, the lower surface of the connecting rod is fixedly connected to a blocking block, and the blocking block is located in the drainage notch, a threaded rod is also provided in the protective pipe, and the threaded rod passes through the movable plate, and the top of the inner wall of the protective pipe is movably connected to a fixed block, and the fixed block is fixedly connected to the top of the threaded rod.
[0006] Through the above technical solution, the present application first installs the secondary drainage pipe and the sewage pipe at the bottom of the sedimentation tank. At this time, the secondary drainage pipe and the protective pipe are in a sealed state. Then, the expanded clay backfill layer 1, the cement mortar leveling layer and the expanded clay backfill layer 2 are laid in sequence from bottom to top to make the base layer more solid. At the same time, the seal between the protective pipe and the secondary drainage pipe can prevent the blockage caused by decoration materials or backfill materials. At this time, the top of the protective pipe and the surface of the expanded clay backfill layer 2 are in the same plane. The rotating fixed block drives the threaded rod to rotate, that is, the movable disk moves upward and drives the blocking block to detach from the drainage gap through the connecting rod. At this time, the drainage gap is in an open state to ensure normal drainage. The connecting rod and the blocking block follow the movement of the movable disk and are located in the protective pipe, which will not affect the drainage effect. Finally, the floor tiles are laid above the expanded clay backfill layer 2 to complete the overall construction.
[0007] Preferably, the number of the drainage gaps is several and they are distributed in a ring shape with the axis of the protection pipe as the center, and the number of the drainage gaps is consistent with the number of the blocking blocks.
[0008] Through the above technical solution, the design of multiple drainage gaps in this application ensures normal drainage.
[0009] Preferably, the upper surface of the blocking block is designed to be inclined, and the shape of the blocking block is adapted to the shape of the drainage gap.
[0010] Through the above technical solution, the shape design of the blocking block and the drainage gap of the present application can prevent the blocking block from getting stuck during the upward movement, ensuring smooth movement of the blocking block.
[0011] Preferably, the top end of the secondary drainage pipe is located at the lowest point of the cement mortar leveling layer, and the protective pipe is located in the second ceramsite backfill layer.
[0012] Through the above technical solution, after the second expanded clay backfill layer is laid, the fixed block in the protective pipe can be operated to open the drainage gap without affecting the normal decoration process.
[0013] Preferably, the connecting rod is made of spring steel, and a sealing treatment is performed between the protective pipe and the secondary drainage pipe.
[0014] Through the above technical solution, when the connecting rod and the blocking block rise with the movable disk, the connecting rod is deformed, so that the blocking block can be completely separated from the drainage gap and located in the protective tube, thereby opening the drainage gap.
[0015] Preferably, a water trap is provided on the secondary drainage pipe, and a filter is fixedly connected inside the secondary drainage pipe.
[0016] By adopting the above technical solution, the beneficial effects of the utility model are:
[0017] 1. The secondary drainage structure of the sedimentation tank can seal the secondary drainage pipe when the sedimentation tank is being renovated, thereby preventing the decoration materials or backfill materials from clogging the pipe opening and affecting the drainage effect. After the decoration is completed, the drainage gap can be opened for normal drainage without affecting the decoration effect and decoration difficulty, thereby solving the problems raised in the background technology.
[0018] 2. The secondary drainage structure of the sedimentation tank is realized through the cooperation of the drainage gap, the blocking block, the threaded rod and the movable plate. The rotating threaded rod can drive the movable plate to move up and down, that is, the movable plate drives the blocking block out of the drainage gap when it rises. The operation can be carried out after the completion of the expanded clay backfill layer and the cement mortar leveling layer, and will not affect the normal construction.
