Description

Technical Field

[0001] The utility model relates to the technical field of subway construction, in particular to a wall ditch protection device. Background Art

[0002] The wall ditch in the subway station hall adopts a cast-in-place concrete structure. Considering that the wall ditch was completed early and has many subsequent processes, it is easy for garbage, materials and other debris to accumulate in the wall ditch, which in turn leads to the blockage of the drain outlet in the ditch. The accumulated water cannot be discharged in time, causing large-scale water accumulation in the station hall, which increases the construction cleaning work and the subsequent cleaning work of the wall ditch.

[0003] Therefore, a technical solution is currently needed to solve the technical problem that after the construction of the wall ditch is completed, subsequent construction will cause accumulation of debris in the wall ditch, thereby causing blockage of the wall ditch. Utility Model Content

[0004] The invention purpose of the utility model is to provide a wall ditch protection device to solve the technical problem that after the wall ditch construction is completed, subsequent construction will cause the wall ditch to accumulate debris, thereby causing the wall ditch to be blocked.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A wall ditch protection device includes a filling box adapted to the shape of the wall ditch, the filling box includes a left side plate, a right side plate, a bottom plate and a top plate, the left side plate, the right side plate, the bottom plate and the top plate enclose a fluid channel, the left side plate is used to abut against the side of the wall ditch close to the road surface, and the right side plate is used to abut against the side of the wall ditch close to the wall surface.

[0007] The utility model discloses a wall ditch protection device. When in use, a filling box is placed in the wall ditch. The accumulated water in the wall ditch flows through a fluid channel formed by a left plate, a right plate, a bottom plate and a top plate, so as to ensure the normal drainage function of the wall ditch. Meanwhile, the sundries falling into the wall ditch will be blocked by the filling box and will not enter the wall ditch in large quantities. After the construction is completed, the filling box can be removed to restore the normal use of the wall ditch without the need for cleaning operations. The wall ditch is protected and the discharge of accumulated water is not affected.

[0008] As a preferred solution of the utility model, a lap plate is provided on one side of the top plate close to the wall, the lap plate is rotatably connected to the top plate, and the lap plate is used to overlap and set on the wall. In order to facilitate the installation and removal of the filling box and the wall-separated groove, the width of the filling box is designed to be slightly smaller than the width of the wall-separated groove. Therefore, after the filling box is embedded in the wall-separated groove, there is a certain gap between the two sides of the filling box and the two sides of the wall-separated groove. By setting a rotatable lap plate on the top of the filling box, after the filling box is installed, the lap plate is rotated so that the lap plate overlaps the wall, the gap between the wall and the filling box is sealed, and debris is prevented from falling into the gap between the filling box and the wall-separated groove, thereby reducing the cleaning work of the wall-separated groove in the later stage.

[0009] As a preferred solution of the utility model, a horizontal plate is provided on the side of the top plate close to the road surface, and the bottom of the horizontal plate is placed against the road surface. The filling box is placed in the wall-away ditch, and the horizontal plate on one side of the top plate is placed against the ground, so as to close the gap between the wall-away ditch on the ground side and the filling box, thereby preventing debris on the ground from falling into the wall-away ditch.

[0010] As a preferred solution of the utility model, the horizontal plate is provided with a connection hole, and the connection hole is equipped with an expansion bolt. After the filling box is installed in the wall trench, the horizontal plate on the side of the filling box can be fixed to the ground by the expansion bolt, so that the filling box is more firmly installed in the wall trench and the water flow of the filling box is ensured to be smooth.

[0011] As a preferred solution of the utility model, the top of the top plate is provided with an arc-shaped groove, which is arranged along the length direction of the top plate, so that the debris falling on the top of the filling box can be collected at the bottom of the arc-shaped groove, which is convenient for cleaning the debris falling in the arc-shaped groove, thereby facilitating the secondary use of the filling box.

[0012] As a preferred solution of the utility model, a lifting ring is provided on the top of the top plate, so that the filling box can be lifted conveniently through the lifting ring, thereby facilitating the transportation, installation and removal of the filling box.

[0013] As a preferred solution of the utility model, the filling box includes a plurality of box segments, and the ends of the plurality of box segments are connected in sequence to form the filling box. The filling box is composed of a plurality of segments, and a suitable number of box segments can be selected according to the length of the wall trench, and assembled and connected in the wall trench, so that the filling box can adapt to the protection work of the wall trenches of different lengths. At the same time, the segmented design of the filling box also facilitates the manufacturing, storage, transportation, installation and removal of the filling box.

[0014] As a preferred solution of the utility model, a plug hole is provided on one end wall of the box segment, and an embedding rod is provided on the other end wall corresponding to the plug hole, and two adjacent box segments are nested and connected through the plug hole and the embedding rod, so that the two adjacent box segments can be accurately docked, which is conducive to the smooth flow of accumulated water in the fluid channel.

[0015] As a preferred solution of the utility model, the left side plate, right side plate, bottom plate and top plate are all stainless steel structural parts. The use environment of the filling box is relatively humid, and ordinary materials are prone to decay or rust in such an environment. However, the various parts of the filling box are made of stainless steel, which prolongs the service life of the filling box, facilitates the reuse of the filling box, and also avoids the filling box from decaying in the wall groove, which makes it inconvenient to clean the wall groove.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] The present application arranges a filling box with a fluid channel in the away-wall ditch. The filling box can block debris that may fall into the away-wall ditch during various construction processes, thereby protecting the away-wall ditch and reducing subsequent maintenance and cleaning work. At the same time, the fluid channel of the filling box can ensure that the accumulated water can pass normally in the away-wall ditch. BRIEF DESCRIPTION OF THE DRAWINGS

The left side plate 11 is used to abut against the side of the ditch close to the road surface, and the right side plate 12 is used to abut against the side of the ditch close to the wall.

[0027] When in use, the filling box 1 is placed in the wall ditch, and the accumulated water in the wall ditch flows through the left plate 11, the right plate 12, the bottom plate 13 and the top plate 14 to form a fluid channel, thereby ensuring the normal drainage function of the wall ditch. At the same time, the debris falling into the wall ditch will be blocked by the filling box 1 and will not enter the wall ditch in large quantities. After the construction is completed, the filling box 1 can be removed to restore the normal use of the wall ditch without the need for cleaning operations, thereby protecting the wall ditch while not affecting the discharge of accumulated water.

[0028] Furthermore, a lap plate 141 is provided on one side of the top plate 14 close to the wall, and the lap plate 141 is rotatably connected to the top plate 14 by a hinge. The lap plate 141 is used for lap-connecting on the wall. In order to facilitate the installation and removal of the filling box 1 and the wall-separated groove, the width of the filling box 1 is designed to be slightly smaller than the width of the wall-separated groove. Therefore, after the filling box 1 is embedded in the wall-separated groove, there is a certain gap between the two sides of the filling box 1 and the two sides of the wall-separated groove. By setting a rotatable lap plate 141 on the top of the filling box 1, after the filling box 1 is installed, the lap plate 141 is rotated so that the lap plate 141 overlaps the wall, thereby sealing the gap between the wall and the filling box 1, preventing debris from falling into the gap between the filling box 1 and the wall-separated groove, and reducing the later cleaning work of the wall-separated groove.

[0029] Furthermore, a transverse plate 142 is provided on the side of the top plate 14 close to the road surface, and the bottom of the transverse plate 142 is placed against the road surface.

[0030] Furthermore, the transverse plate 142 is provided with a connecting hole, and the connecting hole is equipped with an expansion bolt 143. After the filling box 1 is installed in the wall trench, the transverse plate 142 on the side of the filling box 1 can be fixed to the ground by the expansion bolt 143, so that the filling box 1 is installed more firmly in the wall trench, ensuring smooth water flow in the filling box 1.

[0031] Furthermore, an arc-shaped groove 144 is provided on the top of the top plate 14, and the arc-shaped groove 144 is arranged along the length direction of the top plate 14, so that the debris falling on the top of the filling box 1 can be collected at the bottom of the arc-shaped groove 144, which is convenient for cleaning the debris falling in the arc-shaped groove 144, thereby facilitating the secondary use of the filling box 1.

[0032] Furthermore, a lifting ring 145 is provided on the top of the top plate 14 , so that the filling box 1 can be lifted up conveniently by the lifting ring 145 , thereby facilitating the transportation, installation and removal of the filling box 1 .
