Abstract
Description
Technical Field
[0001] This application relates to the technical field of drainage systems, and in particular to a drainage system for foundation formwork. Background Technology
[0002] During the construction of the foundation, after the foundation layer is poured, a brick formwork needs to be built around the foundation layer. The foundation layer and the brick formwork are used to form the foundation template, which is used for subsequent reinforcement binding and concrete pouring.
[0003] Because the interior of the foundation formwork is relatively enclosed, rainwater can easily accumulate inside, causing water accumulation and affecting subsequent rebar tying and concrete pouring. Currently, the common method to address water accumulation inside the foundation formwork is to use a water pump to remove the water.
[0004] Regarding the aforementioned technologies, water accumulation inside the foundation formwork mainly occurs at the bottom and corners of the foundation formwork. When using water pumps for pumping, it is usually necessary to deploy a large number of water pumps or frequently move the water pumps to various water accumulation points for pumping operations, which is quite inconvenient overall. Therefore, there is room for improvement. Utility Model Content
[0005] To facilitate the drainage of water accumulated inside the foundation formwork, this application provides a foundation formwork drainage system.
[0006] This application provides a drainage system for foundation formwork, which adopts the following technical solution: A drainage system for a foundation formwork includes a foundation formwork, wherein the foundation formwork includes a cushion layer and a brick formwork is constructed around the outer periphery of the cushion layer. A concrete drainage layer is laid on the upper surface of the cushion layer. A gap is left between the outer periphery of the concrete drainage layer and the inner periphery of the brick formwork to form an annular water collection ditch. A drainage pipe is inserted through the bottom of the brick formwork and is connected to the annular water collection ditch.
[0007] By adopting the above technical solution, during rainy weather, the water accumulated inside the foundation formwork can flow into the ring-shaped water collection ditch through the concrete drainage layer, and then be discharged to the outside of the foundation formwork through the drainage pipe, thus realizing the discharge of water accumulated inside the foundation formwork. Compared with the traditional method of frequently moving water pumps to various water accumulation points to pump water, this method effectively improves the drainage effect of water accumulated inside the foundation formwork and facilitates better drainage of water accumulated inside the foundation formwork.
[0008] Preferably, it also includes an external drainage component, which includes a water collection well and a drainage ditch buried in the soil surrounding the foundation template; the end of the drainage pipe away from the foundation template extends above the drainage ditch and communicates with the drainage ditch; the drainage ditch communicates with the water collection well; and a submersible pump is installed in the water collection well.
[0009] By adopting the above technical solution, the accumulated water discharged through the drainage pipe can be discharged into the drainage channel and then flow into the collection well. The submersible pump inside the collection well will periodically pump out the accumulated water, which is conducive to the directional discharge of accumulated water from the foundation formwork and prevents the accumulated water from accumulating in the soil outside the foundation formwork after being discharged, thus preventing the soil from having excessively high water content.
[0010] Preferably, a prefabricated drainage ditch is embedded in the middle of the concrete drainage layer, and the two ends of the prefabricated drainage ditch are open to form drainage ends, and the drainage ends are all connected to the annular water collection ditch.
[0011] By adopting the above technical solution, the water accumulated on the surface of the concrete drainage layer can flow into the precast drainage ditch, and then into the ring-shaped water collection ditch, which is conducive to improving the drainage effect inside the foundation formwork.
[0012] Preferably, a PVC pipe is installed inside the prefabricated drainage ditch, and several water-permeable holes are opened on the outer periphery of the PVC pipe. The inner cavity of the prefabricated drainage ditch is also filled with a layer of crushed stone, and the crushed stone layer covers the PVC pipe.
[0013] By adopting the above technical solution, a stable drainage channel is formed in the precast drainage ditch using perforated PVC pipes and crushed stone layer, which restricts sand and gravel debris inside the foundation formwork from flowing into the precast drainage ditch with accumulated water, thus preventing blockage of the precast drainage ditch.
[0014] Preferably, each of the drainage ends of the prefabricated drainage ditch is equipped with a grating plate.
[0015] By adopting the above technical solution, the drainage ends of the precast drainage ditch are blocked by the grating plate, which limits the loss of the crushed stone layer in the precast drainage ditch through the drainage ends.
[0016] Preferably, a filter screen is installed at one end of the drain pipe that connects to the annular water collection ditch.
[0017] By adopting the above technical solution, a filter screen is installed at the end of the drain pipe to intercept sand and gravel debris carried in the accumulated water. This helps to limit the accumulation of sand and gravel debris that can clog the drain pipe and affect its normal drainage.
[0018] Preferably, the PVC pipe is wrapped with a dense mesh fabric, which covers the water-permeable holes.
[0019] By adopting the above technical solution, during the drainage process, the fine impurities such as mud and sand carried by the accumulated water are blocked from entering the PVC pipe through the water-permeable holes, which helps to prevent mud and sand from clogging the PVC pipe and allows the drainage pipe to drain smoothly.
[0020] Preferably, an annular water-stop wing plate is coaxially connected to the outer periphery of the drainage pipe, and the annular water-stop wing plate is located inside the brick mold.
[0021] By adopting the above technical solution, the gap at the connection between the drainage pipe and the brick formwork is sealed by the annular water-stop wing plate, which limits the seepage of the water in the subsequent annular water collection ditch to the outside of the brick formwork through the gap between the drainage pipe and the brick formwork.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Water accumulated inside the foundation formwork can flow into the annular drainage ditch through the concrete drainage layer, and then be discharged through the drainage pipe connected to the annular drainage ditch, which helps to improve the drainage efficiency of water accumulated inside the foundation formwork.
[0023] 2. By setting up external drainage components, the water discharged from inside the foundation formwork can be directed to the sump well via the prefabricated drainage channel, and then pumped out by the submersible pump inside the sump well, thus preventing the water discharged from inside the foundation formwork from causing the soil outside the foundation formwork to have excessive moisture content.
[0024] 3. By setting up precast drainage ditches in the concrete drainage layer, part of the concrete drainage layer can flow into the ring-shaped water collection ditch through the precast drainage ditch, which facilitates better drainage of water accumulated inside the foundation formwork.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0032] This application discloses a drainage system for a foundation formwork, referring to... Figure 1 and Figure 2 The system includes a foundation formwork 1; the foundation formwork 1 includes a pad layer 11, with a brick formwork 12 circumferentially built around the outer periphery of the pad layer 11. A concrete drainage layer 2 is poured and laid on the upper surface of the pad layer 11, with a gap between the outer periphery of the concrete drainage layer 2 and the inner periphery of the brick formwork 12 to form an annular drainage ditch 3. Several drainage pipes 4 are inserted through the bottom of the brick formwork 12 and communicate with the annular drainage ditch 3. One end of the drainage pipe 4 extends into the annular drainage ditch 3 and communicates with it, while the other end of the drainage pipe 4 extends outward from the brick formwork 12. Subsequently, water accumulated inside the foundation formwork 1 can flow into the annular drainage ditch 3 through the drainage pad layer 11 and then be discharged through the drainage pipes 4 on the annular drainage ditch 3.
[0033] Reference Figure 1 and Figure 2 An external drainage system is installed around the outer perimeter of the foundation formwork 1. This system includes four water collection wells 5, located at the four apex corners of the foundation formwork 1. Each water collection well 5 is embedded in the soil, and a drainage ditch 51 is installed between adjacent water collection wells 5. Both ends of the drainage ditch 51 are connected to the adjacent water collection well 5. The drainage ditch 51 is embedded in the soil and is positioned below the drainage pipe 4. The end of the drainage pipe 4 furthest from the annular drainage ditch 3 extends above the nearest drainage ditch 51 to connect with it.
[0034] Water discharged from the foundation formwork 1 via the drainage pipe 4 can be drained into the drainage ditch 51, and then flow into the collection well 5, achieving a directional and concentrated transfer of water. This avoids the situation where water discharged from the drainage pipe 4 is directly discharged into the soil surrounding the foundation formwork 1, leading to excessive soil moisture content. In this embodiment, both the collection well 5 and the prefabricated drainage ditch 21 are prefabricated components, which facilitates construction and installation and allows for subsequent reuse.
[0035] Reference Figure 1 and Figure 2 Each of the 5 water collection wells is equipped with a submersible pump at its bottom. The water outlet pipe at the outlet of the submersible pump extends to the 5 water collection well. The water inside the 5 water collection well can be periodically pumped out through the submersible pump to clean the water inside the 5 water collection well.
[0036] Reference Figure 2 and Figure 3 A filter screen 41 is installed at one end of the drain pipe 4, which is connected to the annular water collection ditch 3. The filter screen 41 at the end of the drain pipe 4 filters out sand and gravel debris carried in the accumulated water, preventing sand and gravel debris from clogging the drain pipe 4. A support ring 411 is formed on the outer periphery of the filter screen 41. The support ring 411 is sleeved on the end of the drain pipe 4 to achieve a stable connection between the filter screen 41 and the drain pipe 4.
[0037] Reference Figure 2 and Figure 3 A ring-shaped water-stop wing plate 40 is coaxially connected to the outer periphery of the drainage pipe 4. The ring-shaped water-stop wing plate 40 is located inside the brick formwork 12. The ring-shaped water-stop wing plate 40 is used to seal the connection between the drainage pipe 4 and the brick formwork 12, limiting the water accumulation in the subsequent annular precast drainage ditch 21 from seeping out of the outside of the brick formwork 12 through the gap between the drainage pipe 4 and the brick formwork 12, thus preventing the soil outside the brick formwork 12 from having excessive water content.
[0038] Reference Figure 2 and Figure 4 A steel mesh is embedded inside the concrete drainage layer 2 to improve its overall strength. A precast drainage ditch 21 is also embedded in the concrete drainage layer 2, located within it. Both ends of the precast drainage ditch 21 extend to the sides of the concrete drainage layer 2, with openings at both ends forming drainage ends that are connected to the annular drainage ditch 3. Subsequent water accumulation on the concrete drainage layer 2 can be drained into the annular precast drainage ditch 21 via the precast drainage ditch 21, which helps to accelerate the drainage of water inside the foundation formwork 1.
[0039] A PVC pipe 22 is installed inside the prefabricated drainage ditch 21. Several permeable holes are opened on the outer periphery of the PVC pipe 22. Both ends of the PVC pipe 22 extend to the ends of the prefabricated drainage ditch 21, and both ends of the PVC pipe 22 are open. A gravel layer 23 is filled inside the prefabricated drainage ditch 21, covering the outer periphery of the PVC pipe 22. The gravel layer 23, in conjunction with the PVC pipe 22, forms a stable drainage channel within the prefabricated drainage ditch 21, facilitating the more stable drainage of accumulated water into the annular collection ditch 3.
[0040] The PVC pipe 22 is wrapped with a fine-mesh mesh, which covers the permeable holes on the outer perimeter of the PVC pipe 22. The two ends of the mesh are secured to the outer perimeter of the PVC pipe 22 with steel wire to ensure a stable fit. During drainage, the mesh filters out fine impurities such as mud and sand carried in the accumulated water, preventing mud and sand from accumulating and clogging the PVC pipe 22, thus facilitating smooth drainage.
[0041] Reference Figure 4 and Figure 5 Each prefabricated drainage ditch 21 is equipped with a grating plate 211 at its drainage end, which is fixed to the drainage end of the prefabricated drainage ditch 21 with bolts. The grating plate 211 covers the drainage end and blocks and limits the drainage end of the prefabricated drainage ditch 21, preventing the crushed stone layer 23 in the prefabricated drainage ditch 21 from flowing into the annular water collection ditch 3 due to repeated flushing by accumulated water.
[0042] The implementation principle of this embodiment is as follows: when there is water inside the foundation formwork 1, the water can flow into the annular water collection ditch 3 through the concrete drainage layer 2, or flow into the precast drainage ditch 21 through the concrete drainage layer 2, and then flow into the annular water collection ditch 3 through the PVC pipe 22 in the precast drainage ditch 21. The water entering the annular water collection ditch 3 is discharged from the foundation formwork 1 through several drainage pipes 4 on the brick formwork 12, and flows into the drainage trough 51 outside the foundation formwork 1. Finally, it flows into the water collection well 5 through the drainage trough 51, effectively improving the drainage efficiency of the water inside the foundation formwork 1.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
