Description

Technical Field

[0001] The utility model relates to the technical field of off-wall ditch, in particular to an anti-leakage off-wall ditch. Background Art

[0002] A gutter is a drainage system usually used around the roof and walls of a building. Its function is to collect and discharge rainwater to prevent water from penetrating from the roof and walls into the interior of the building, thereby protecting the structure and walls of the building. The ditch is usually located at the bottom of the wall or wall, which can collect rainwater and direct it into a drainage pipe or a collection tank.

[0003] In subway decoration, the drainage ditch is a drainage ditch along the subway wall, which is the same as the ordinary ditch, poured with concrete and painted with waterproof paint. The subway wall is pre-constructed, and the drainage ditch is installed on one side of the wall in the later construction. Since the wall and the drainage ditch are not cast as one piece, there will still be a gap between the drainage ditch and the subway wall. Condensation water or seepage on the wall will enter the subway station through the gap, which will not play a normal drainage role and may even affect the normal operation of the subway.

[0011] The utility model discloses an anti-leakage wall ditch, such as Figure 1-3 As shown, it includes a vertically arranged water retaining plate 1, a ditch base 2 is provided at the bottom between the water retaining plate 1 and the side wall, and the water retaining plate 1 is higher than the ditch base 2 by a certain distance to prevent the water in the wall ditch from rising and entering the subway station.

[0012] In order to fill the gap between the wall ditch and the side wall, a first curved plate 3 is provided on the top of the ditch base 2, one end of the first curved plate 3 extends into the side wall, and a second curved plate 4 is also installed in the side wall and located above the first curved plate 3. One end of the second curved plate 4 is arranged tangent to the side wall, and the other end of the second curved plate 4 is fixedly connected to the end of the first curved plate 3 extending into the side wall, and the opening of the second curved plate 4 corresponds to the opening of the first curved plate 3.

[0013] In the structural arrangement of the above-mentioned arc plates, the second arc plate 4 effectively fills the gap between the wall ditch and the side wall, and the first arc plate 3 and the second arc plate 4 can form a guide for the leaking water. The leaking water flowing down through the side wall will eventually drip onto the first arc plate 3 under the action of gravity and completely enter the wall ditch, thereby realizing the corresponding drainage operation, avoiding the leaking water from entering the gap between the wall ditch and the side wall, and reducing the impact of the leaking water on the normal operation inside the station.

[0014] Furthermore, in order to ensure the strength of the water retaining plate 1, a plurality of vertical ribs 5 are arranged along the length direction in the water retaining plate 1, and the arrangement of the vertical ribs 5 can also enhance the integrity of the water retaining plate 1. In order to improve the connection strength between the first curved plate 3 and the ditch base 2, a plurality of support rods 6 are installed in the ditch base 2, and the first curved plate 3 is located on the support rods 6, wherein the support rods 6 are arranged vertically and can serve as a framework for casting the ditch base 2. At the same time, the top of the support rods 6 and the first curved plate 3 can be fixedly connected as a whole by welding or bolting to improve the strength of the overall off-wall ditch base.

[0015] Furthermore, in order to achieve normal drainage in the wall ditch, Figure 4 As shown, a plurality of water leakage holes 7 are provided in the length direction of the first arc-shaped plate 3, and a filter grate 8 is provided at the top of each water leakage hole 7, and a drain pipe 9 is connected to the bottom of the water leakage hole 7, and the drain pipe 9 is arranged obliquely in the ditch base 2. The filter grate 8 can block solid dirt in the wall ditch, and the leakage water can enter the drain pipe 9 through the filter grate 8, and through the oblique arrangement state, the leakage sewage is discharged outward under the action of gravity.

[0016] Furthermore, in order to improve the overall waterproof performance of the wall ditch, a first waterproof layer 10 is provided on the first curved plate 3, a second waterproof layer 11 is provided at the bottom of the second curved plate 4, and a third waterproof layer 12 is provided on the inner side of the water retaining plate 1. The third waterproof layer 12 is located on the upper side of the first waterproof layer 10. The arrangement of the above-mentioned waterproof layers can effectively prevent sewage from leaking inside the wall ditch, thereby ensuring the normal drainage function of the wall ditch and extending the service life of the wall ditch.

[0017] Furthermore, in order to facilitate the installation of the first curved plate 3 and the second curved plate 4 in the side wall, the first curved plate 3 and the second curved plate 4 are both semicircular arc tubes, and the center of the first curved plate 3 and the center of the second curved plate 4 are located on the same horizontal straight line. The above-mentioned semicircular arc tube can be cut into two halves by an existing circular tube and pre-buried in advance during the side wall construction, and sufficient installation grooves are left for the first curved plate 3 to facilitate the sealed welding and fixed connection between the two curved plates, so that the two curved plates form a whole, and the leaking water completely enters the wall groove under the guidance of the curved plate, avoiding the seepage water from entering the subway station and affecting the subsequent normal operation.
