Description

Technical Field

[0001] The invention relates to the field of construction site of building engineering, and in particular to a temporary drainage device at a construction site and an implementation method thereof. Background Art

[0002] At present, there are a lot of temporary water use links in construction projects. For example, the poured concrete structure needs water spraying maintenance, wall plastering and slurry throwing and other wet operations. In addition, during the construction process, the construction project cannot be closed, and rain will fall into the building. Since the construction project does not have the conditions to install permanent drainage facilities, the wastewater and rainwater generated in the production process will accumulate in large quantities on the floors, seriously affecting safe and civilized construction and the subsequent construction process. How to do a good job of temporary drainage at the construction site is a common problem faced in construction projects.

[0003] To solve the problem of water accumulation in floors, current construction projects usually adopt the method of drilling holes in the floor slabs with a water drill and knocking down the concrete structures that are higher than the floor surface at the inner and outer edges of the floors to drain water.

[0004] This temporary drainage method has the following disadvantages:

[0005] (1) There are a large number of pre-buried mechanical and electrical conduits in the building structure floor. The holes opened behind the floor destroyed the pre-buried conduits, making it impossible to pass through the conduits later and requiring the re-laying of exposed conduits. The fire resistance of exposed conduits is lower than that of concealed conduits in the floor, which poses a fire safety hazard. Re-laying the conduits increases the project cost and affects the appearance.

[0006] (2) Remove the concrete structures that are higher than the floor at the inner and outer edges of the floors, which will affect the subsequent construction of handrails, secondary walls, curtain walls, etc.

[0007] (3) Holes are opened in the floor slabs and the concrete structure at the edge of the floor is knocked down, which destroys the structural integrity and in serious cases affects the structural safety.

[0008] (4) Water from the floor flows into the next floor along the later-opened floor holes and damaged floor edges, causing water to accumulate on the lower floor. The structure of the lower floor needs to be destroyed again for drainage. In addition, the accumulated water will contaminate the ceiling and wall plastering of the lower floor as it flows to the next floor.

[0009] (5) Unorganized drainage methods that damage the structure, such as opening holes in the floor slabs and knocking off the edges of floors, will lead to an increase in the flooded area inside the building, seriously affecting safe and civilized construction and the implementation of subsequent construction procedures. Summary of the invention

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a temporary drainage device for a construction site, the temporary drainage device comprising an end sealing cover plate component, a socket water-stopping joint component, a vertical straight pipe section component, a socket elbow component, an inclined straight pipe section component, and a socket fixed elbow component. The socket water-stopping joint component, the vertical straight pipe section component, the socket elbow component, the inclined straight pipe section component, and the socket fixed elbow component are all pipe parts. The socket water-stopping joint component and the socket elbow component are connected through the vertical straight pipe section component, the socket elbow component and the socket fixed elbow component are connected through the inclined straight pipe section component, and the socket fixed elbow component is also provided with an end sealing cover plate component.

[0011] By means of the above structure, a temporary drainage device is composed of end sealing cover components, socket water stop components, vertical straight pipe section components, socket elbow components, inclined straight pipe section components and socket fixed elbow components, and is installed in advance before pouring concrete, avoiding the problem of opening holes behind the floor slab and damaging the embedded pipeline. After the temporary drainage is completed, the plugging can be completed by filling concrete without disassembly and recycling, thereby making the temporary drainage device easy to install and does not affect other subsequent operations during implementation. At the same time, it is suitable for temporary drainage of each floor slab.

[0012] Preferably, the upper end pipe opening of the socket water-stop component is provided with a socket water-stop component cover, the lower end pipe opening is provided with a socket, the inner wall of the socket water-stop component pipe is provided with a socket, and the outer side wall of the socket water-stop component pipe is provided with a water stop ring.

[0013] It can be seen that the cover provided by the socket-and-spigot water-stop joint component can effectively prevent concrete from flowing into the device and blocking the drainage channel when pouring concrete. It is provided with a water-stop ring cast in the concrete to prevent water from seeping along the outer wall of the device. The socket at the lower end of the pipe mouth is used for socket connection with the vertical straight pipe section component, and a socket space is provided to facilitate the installation of floor drains or pipes inside the building.

[0014] Preferably, the pipe openings at the upper and lower ends of the socket elbow component are both provided with sockets, and the angle of the bend is 45 degrees.

[0015] It can be seen that the socket of the socket elbow component is used to achieve a socket connection with the vertical straight pipe section component, and the angle of the bend is 45 degrees, which improves the drainage smoothness of the temporary drainage device.

[0016] Preferably, a socket is provided at one end of the pipe opening of the socket-and-spigot fixed elbow component, and a socket-and-spigot fixed elbow component cover is provided at the other end of the pipe opening. The socket-and-spigot fixed elbow component is also provided with a socket space on the inner pipe wall near the socket-and-spigot fixed elbow component cover, and the angle of the bend is 45 degrees.

[0017] It can be seen that the connection with the inclined straight pipe section component is achieved through the socket of the socket-and-spigot fixed elbow component. The provided cover prevents concrete from flowing into the device and blocking the drainage channel when pouring concrete. The socket space of the socket-and-spigot fixed elbow component facilitates the subsequent installation of drainage risers and horizontal pipes along the inner and outer edges of the building at the construction site. The horizontal pipe is connected with the socket space of the socket-and-spigot fixed elbow component through the socket to achieve organized temporary drainage at the construction site. At the same time, the angle of the bend is 45 degrees, which improves the drainage smoothness of the temporary drainage device.

[0018] Preferably, the radius of the cover of the socket-and-spigot fixed elbow component is larger than the radius of the pipe mouth of the socket-and-spigot fixed elbow component, and three fixing openings are opened on the cover outside the pipe mouth of the socket-and-spigot fixed elbow component, a fixing opening reinforcement rib is provided between the fixed opening and the cover, and a vertical reinforcement rib is provided between the cover and the socket-and-spigot fixed elbow component.

[0019] It can be seen that the fixing of the socket-and-spigot fixed elbow component is achieved through the fixing port, thereby achieving the fixation of the temporary drainage device. The fixing port reinforcement rib plays the role of fixing the fixing port. At the same time, vertical reinforcement ribs are arranged to improve the strength of the socket-and-spigot fixed elbow component.

[0020] Preferably, the end sealing cover plate component, the socket water stop component, the vertical straight pipe section component, the socket elbow component, the inclined straight pipe section component and the socket fixed elbow component are all made of hard polyvinyl chloride.

[0021] It can be seen that by adopting rigid polyvinyl chloride, the applicability of temporary drainage devices is improved due to its low density, good tensile strength, good water resistance, oil resistance and resistance to chemical corrosion.

[0022] Preferably, the wall thickness of the vertical straight pipe section component matches the socket at the socket water stop component and the socket elbow component.

[0023] It can be seen that by matching the thickness of the pipe wall with the sockets at the socket water-stop joint components and the socket elbow components, after the length of the vertical straight pipe section components is cut according to actual needs on site, the connection between the components can be achieved without other devices, thereby further improving the applicability of the device and making installation more convenient.

[0024] Preferably, the pipe wall thickness of the oblique straight pipe section component matches the socket of the socket elbow component and the socket fixed elbow component.

[0025] It can be seen that by matching the thickness of the pipe wall with the socket of the socket elbow component and the socket fixed elbow component, and cutting the length of the inclined straight pipe section component according to actual needs on site, the connection between the components can be achieved without other devices, thereby further improving the applicability of the device and making installation more convenient.

[0026] Preferably, the end sealing cover component includes a blind plate and a socket, the socket is arranged at the edge of the blind plate, the radius of the blind plate is slightly smaller than the radius of the inner pipe wall of the socket fixed elbow component, and the length of the socket is equal to the distance from the pipe mouth of the socket fixed elbow component to the socket space provided on its inner pipe wall.

[0027] It can be seen from this that by making the radius slightly smaller than the inner tube wall of the socket-and-spigot fixed elbow component and the length equal to the distance from the pipe mouth of the socket-and-spigot fixed elbow component to the socket space provided on its inner tube wall, the end sealing cover component can be firmly and fixedly installed at the pipe mouth of the socket-and-spigot fixed elbow component during subsequent sealing, so that no convex or concave parts will appear in the subsequent processing, thereby ensuring the progress of the sealing operation without affecting the overall appearance of the building.

[0028] A method for implementing a temporary drainage device at a construction site, the method comprising the following steps:

[0029] a) Use steel nails to pass through the three fixing holes set on the socket-and-spigot fixed elbow component, and fix the socket-and-spigot fixed elbow component on the template, so that the cover will be close to the template.

[0030] b) In order of front to back, the socket fixed elbow components, oblique straight pipe components, socket elbow components, vertical straight pipe section components, and socket water stop joint components are connected in turn through the socket method to form a temporary drainage device at the construction site, and the socket joints are all coated with glue for bonding, that is, the oblique straight pipe section component is inserted into the socket of the socket fixed elbow component to be connected with the socket fixed elbow component, the socket elbow component is connected with the oblique straight pipe section component through the socket of the socket elbow component, the vertical straight pipe section component is inserted into the socket of the socket elbow component to be connected with the socket elbow component, the socket water stop joint component is connected with the vertical straight pipe section component through the socket of the vertical straight pipe section component, and the length of the vertical straight pipe section component and the oblique straight pipe section component are directly cut according to needs.

[0031] c) After the device is embedded and firmly fixed, pour the floor concrete.

[0032] d) When the concrete reaches a certain strength, the formwork is removed and the cover of the socket-and-spigot fixed elbow component is exposed on the side of the beam, and the cover of the socket-and-spigot water-stop component is exposed on the floor.

[0033] e) Knock open the sealing parts of the socket-and-spigot fixed elbow components and the socket-and-spigot water-stop joint components at the pipe openings of the corresponding socket-and-spigot fixed elbow components and the socket-and-spigot water-stop joint components, and the accumulated water on the floor can be discharged along the channel inside the device.

[0034] f) Drainage risers and horizontal pipes are set along the inner and outer edges of the building. The horizontal pipes are connected with the sockets of the socket-and-spigot fixed elbow components through sockets to achieve organized temporary drainage at the construction site.

[0035] g) When there is no water accumulation on the floor at a later stage, the end sealing cover plate component is inserted into the socket of the socket-fixed elbow component, and concrete is poured into the device to achieve the sealing of the device.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] (1) The present invention uses a pre-buried method to install a temporary drainage device. Compared with the traditional method of opening a hole for drainage, it will not damage the pre-buried pipelines, resulting in the inability to pass through the wire pipes in the later stage and the need to re-lay the exposed wire pipes. It eliminates the fire safety hazard caused by the fire resistance time of the exposed wire pipes being lower than that of the concealed wire pipes in the floor slab, and is safer.

[0038] (2) The present invention does not need to demolish the concrete structure above the floor at the inner and outer edges of the floor. Compared with traditional operations, it does not affect the subsequent construction of handrails, secondary walls, curtain walls, etc., and effectively speeds up the construction progress.

[0039] (3) Compared with the traditional operation of opening holes in the floor slab, the present invention ensures the structural integrity and does not affect the structural safety. At the same time, it prevents the accumulation of water from flowing down and polluting the ceiling and wall plastering of the lower layer. The present invention improves safety and maintains the beauty of the building structure.

[0040] (4) The present invention realizes the organization of temporary drainage at the construction site by pre-embedding, which is beneficial to the cost protection of other construction processes. BRIEF DESCRIPTION OF THE DRAWINGS
