Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a drainage device and construction method for water seepage in the foundation slab. Background Technology

[0002] For water seepage in the structural base slab, it is generally necessary to locate the leak point before the construction of the building surface layer, and then seal it with polyurethane on the structural base slab. After sealing, observe to ensure that no water seepage occurs before constructing the building surface layer.

[0003] However, if water leakage is found in the basement floor slab after the building surface layer has been completed, water will flow through the gaps between the structural layer and the building surface layer, making it difficult to find the leak point.

[0004] The current technology involves cutting open a large area of ​​the building's surface layer to locate and seal the leak, then restoring the surface layer. However, large-scale dismantling of the surface layer generates a large amount of construction waste. Water flows through gaps between the structural layer and the surface layer, making it difficult to locate the leak. If only a small portion of the surface layer is removed, the leak may not be located, rendering the sealing ineffective and wasting manpower, financial resources, and materials. Furthermore, pouring new concrete will incur costs. In short, the method of cutting open the surface layer to locate the leak, sealing it, and then restoring the surface layer is extremely costly and not universally applicable. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art and provide a drainage device and construction method for water seepage in the basement slab, thereby solving the problem of water seepage and leakage on the building surface caused by leakage points in the existing basement structure basement slab.

[0006] The technical solution to achieve the above objective is: a drainage device for water seepage in the base plate, comprising: a drainage plate, which is horizontally placed on the seepage surface and collects the seeping water on the drainage plate; a plate body, which covers the drainage plate; a support leg assembly, which is disposed below the plate body; and a drain pipe, one end of which is connected to the drainage plate and the other end extends to a collection well, for transporting the water collected on the drainage plate to the collection well.

[0007] In this invention, a drainage device for seepage in the base plate is provided. The seepage water is collected by a drainage plate and transported to the nearest collection well by a drainage pipe. This prevents the seepage water from spreading on the surface of the base plate and affecting the surface layer, thus improving work efficiency and avoiding large-scale cutting of the surface layer that would affect the construction progress.

[0008] A further improvement of the drainage device for water seepage in the base plate of the present invention is that the upper end of the drainage plate is provided with uniformly distributed grooves.

[0012] A further improvement of the drainage device for water seepage in the base plate of the present invention is that the drainage pipe is inserted through the first square pipe.

[0013] A further improvement of the drainage device for water seepage in the base plate of the present invention is that the first square tube is provided with holes for the drainage pipe to pass through.

[0015] A further improvement of the construction method for installing a drainage device at a seepage point in the foundation plate of the present invention is that the step of excavating on the surface layer according to the seepage point to form a water collection trough includes: excavating a pipe trench on the side of the water collection trough near the water collection well.

[0016] A further improvement of the construction method for installing a drainage device at a water seepage point in the base plate of the present invention is that the installation of the drainage device in the water collection tank includes: installing a drainage plate at the bottom of the water collection tank; covering the drainage plate with a plate body; setting a support leg assembly below the plate body; providing a drain pipe, arranging the drain pipe in the pipe trench, and connecting one end of the drain pipe to the drainage plate, and extending the other end to the water collection well, so as to transport the water collected on the drainage plate to the water collection well.

[0024] See Figure 1 and Figure 2 , Figure 1 This diagram shows a structural schematic of a drainage device for water seepage in the base plate according to the present invention. Figure 2 This image shows a side sectional view of a drainage device for water seepage in a base plate according to the present invention. The present invention provides a drainage device for water seepage in a base plate 5, comprising: a drainage plate 1, which is horizontally placed at the seepage surface, and collects the seeping water on the drainage plate 1.

[0026] Plate 2 is placed on top of the drainage plate 1.

[0027] Plate 2 is used to protect the drainage plate 1 and bear the load from above. The thickness and size of the steel plate are selected according to the actual load-bearing requirements and the size of the drainage plate 1, and no specific restrictions are imposed here.

[0028] Support leg assembly 3 is located below the plate 2.

[0029] Among them, the support leg assembly 3 is located on the outside of the hydrophobic plate 1, which further protects the hydrophobic plate 1.

[0030] Drainage pipe 4, one end of which is connected to drainage plate 1 and the other end extends to water collection well, is used to transport the water collected on drainage plate 1 to water collection well.

[0032] The present invention provides a drainage device for water seepage in the base plate 5, wherein the upper end of the drainage plate 1 is provided with uniformly distributed grooves 11.

[0033] The seepage water pressure is used to collect the seepage water into the water collection groove 11 of the drainage plate 1. The grooves 11 are connected to each other to facilitate the flow and discharge of water.

[0034] In this embodiment, the groove 11 is honeycomb-shaped to maximize space utilization and store more permeable water. In other embodiments, the groove 11 can be rectangular or circular; no specific limitation is made here.

[0035] The present invention provides a drainage device for water seepage in the base plate 5, wherein the upper end surface of the plate 2 is provided with texture.

[0036] The textured surface of the upper end of the plate 2 facilitates bonding with the concrete 7 and expands the contact area.

[0037] The present invention provides a drainage device for water seepage in the base plate 5, wherein the outer surface of the plate 2 is coated with a protective layer.

[0038] Among them, the entire outer side of the plate 2 is coated with anti-rust paint to prevent water seepage from corroding the plate 2 and affecting its lifespan.

[0039] See Figure 1 The diagram shows a structural schematic of a drainage device for water seepage in the base plate according to the present invention. The present invention provides a drainage device for water seepage in the base plate 5, wherein the support leg assembly 3 includes: a first square tube 31, which is arranged around the bottom of the plate body 2.

[0040] The first square tube 31 is located on the outside of the hydrophobic plate 1.

[0041] The second square tube 32 is configured in a cross shape and supported in the middle of the bottom of the plate 2.

[0042] In this design, a second square tube 32 is installed at the bottom of the plate 2 to provide support, based on the dimensions of the plate 2, thereby further enhancing the support strength.

[0043] See Figure 1 The diagram shows a structural schematic of a drainage device for water seepage in the base plate according to the present invention. The present invention provides a drainage device for water seepage in the base plate 5, wherein a drain pipe 4 is inserted through a first square pipe 31.

[0044] Among them, the drain pipe 4 passes through the first square pipe 31 and is connected to the drainage plate 1.

[0045] The present invention provides a drainage device for water seepage in the base plate 5, wherein the first square tube 31 is provided with holes for water supply and drainage pipe 4 to pass through.

[0046] The hole is located on the first square pipe 31 near the water collection well, and the diameter of the hole is larger than the diameter of the drain pipe 4 to facilitate the passage of the drain pipe 4.

[0047] See Figure 3 This document illustrates a flowchart of a construction method for installing a drainage device at a water seepage point in a foundation slab according to the present invention. The present invention provides a construction method for installing a drainage device at a water seepage point in a foundation slab, using the aforementioned drainage device for water seepage in foundation slab 5, comprising the following steps:

[0048] Perform step S210: Locate the water seepage points on the 5th surface layer of the base plate.

[0049] In this step, the point with the most water seepage on the 5th surface layer of the base plate is located, and then step S220 is executed.

[0050] Step S220: Excavate on the surface layer according to the seepage point to form a water collection trough 6.

[0051] In this process, the size of the excavated water collection trough 6 is larger than the size of the diversion device, and the excavation depth of the water collection trough 6 is the thickness of the surface layer of the bottom plate 5. Then, step S230 is executed.

[0052] Perform step S230: Install a diversion device in the water collection tank 6.

[0053] If the depth of the water collection trough 6 in the surface layer cannot meet the burial conditions of the diversion device, the bottom of the water collection trough 6 is excavated towards the structural slab to ensure that the water collection trough 6 can accommodate the diversion device and meet the conditions for concrete 7 coverage. Then, step S240 is executed.

[0054] Step S240: Pour concrete 7 into the water collection tank 6 to bury the diversion device.

[0055] The use of micro-expansion fine stone concrete 7 to cover the drainage device can ensure that it will not deform or crack under normal vehicle traffic load.

[0056] In this embodiment, it is necessary to ensure that the thickness of the 7-layer concrete above the slab 2 is greater than or equal to 50mm, so that the combined effect of the slab 2 and the 7-layer concrete can resist the normal traffic load of vehicles.

[0057] See Figure 4 The diagram shows a flow chart of step S220 of the present invention. The present invention provides a construction method for installing a drainage device at a water seepage point in the foundation slab, wherein step S220 includes:

[0058] Step S221: Excavate a pipe trench on the side of the water collection tank 6 near the water collection well.

[0059] The trench excavation depth extends to the top of the bottom slab 5 structural layer. When setting up the drainage trench, attention should be paid to the slope to ensure that the water in the drainage pipe 4 can flow naturally towards the collection well and not accumulate in the opposite direction.

[0060] See Figure 5 The diagram shows a flow chart of step S230 of the present invention. The present invention provides a construction method for installing a drainage device at a water seepage point in the foundation slab, wherein step S230 includes:

[0061] Step S231: Install the drainage plate 1 at the bottom of the water collection tank 6.

[0062] In this process, the hydrophobic plate 1 is placed horizontally at the bottom of the water collection tank 6, and then step S232 is executed.

[0063] Perform step S232: Cover the plate body 2 on top of the hydrophobic plate 1.

[0064] In this process, plate 2 covers the top of hydrophobic plate 1, bears the pressure from above, and protects hydrophobic plate 1. Then, step S233 is executed.

[0065] Step S233: Install the support leg assembly 3 below the plate 2.

[0066] Among them, the support leg assembly 3 provides support to the plate 2, which can disperse the load on the plate 2 and further protect the hydrophobic plate 1. Then, step S234 is executed.

[0067] Step S234: Provide a drain pipe 4, arrange the drain pipe 4 in the pipe trench, connect one end of the drain pipe 4 to the drainage plate 1, and extend the other end to the water collection well, so as to transport the water collected on the drainage plate 1 to the water collection well.

[0068] Drainage pipe 4 is laid along the structural layer of the base slab 5. Observe whether the seepage can flow along drainage pipe 4 before pouring concrete 7.
