[0017] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Reference Figures 1 to 3 As shown, the utility model provides a bottom plate pressure relief structure of a riverside basement, comprising: a water filter pipe 1 and a drain pipe 2.

[0020] In this embodiment, the basement floor comprises a plurality of precast slabs 3 and postcast strip slabs 4. The postcast strip slabs 4 connect two adjacent precast slabs 3. A waterstop steel plate 31 is embedded in the construction joint between the postcast strip slabs 4 and the precast slabs 3.

[0021] A plurality of holes are formed below the post-casting strip plate 4. The holes are arranged vertically and filled with filter material 5.

[0022] As a preferred embodiment, the filter material 5 is sand and gravel.

[0023] In this embodiment, the lower portion of the water filter pipe 1 is buried in the filter material 5. The lower portion of the water filter pipe 1 is formed with a plurality of first water seepage holes.

[0024] See Figure 2 As shown, the upper portion of the filter pipe 1 extends into the post-cast strip 4. A waterstop ring plate 11 is formed on the exterior of the upper end of the filter pipe 1. A first water diversion pipe 12 is embedded in the post-cast strip 4. One end of the first water diversion pipe 12 is connected to the upper end of the filter pipe 1. The other end of the first water diversion pipe 12 is connected to the water collection well in the basement floor.

[0025] See Figure 3 As shown, drain pipe 2 is buried in the construction joint. It is installed above water-stopping steel plate 31 and runs along the length of the construction joint. Drain pipe 2 is provided with a second seepage hole. Drain pipe 2 is connected to the water collection well via a second water diversion pipe 21. Drain pipe 2 is covered with filter cloth.

[0026] As a preferred embodiment, the filter cloth is a geotextile.

[0027] A cushion layer 6 is poured below the basement floor. A waterproof roll 7 is laid on the cushion layer 6. The waterproof roll 7 is turned up and wrapped around the outside of the filter pipe 1. The waterproof roll 7 extends to the bottom of the water stop ring plate 11.

[0028] The root of the water stop ring plate 11 is provided with a water-swelling water stop strip 8. The water-swelling water stop strip 8 is arranged along the circumferential direction of the water filter pipe 1 in a circle.

[0029] The basement floor is paved with a drain plate 9. A floor 10 is formed on the drain plate 9. A first water diversion pipe 12 and a second water diversion pipe 21 are laid in the drain plate 9.

[0030] During the foundation pit excavation process, the foundation pit holes are drilled according to the design drawings. The top elevation of the filter pipe installed in the hole is lower than the top surface elevation of the basement floor. When the basement floor is poured, a water stop ring plate should be welded to the pipe wall of the filter pipe. The water stop ring plate is welded with a circular steel ring, and the inner diameter of the water stop ring plate is the same as the filter pipe (steel pipe). The width of the water stop ring plate is 60mm and the thickness is 4mm. The water stop ring plate is welded on both sides. The water stop ring plate is set 30-40cm above the bottom of the base plate to prevent groundwater from rising along the well wall. A water-expanding rubber water stop strip is installed at the junction of the water stop ring plate and the filter pipe, and the waterproof membrane is attached to the water stop ring plate.

[0031] When the base plate post-cast strip is cast and sealed, a blind ditch is set in the middle of the post-cast strip. A square drain pipe is buried in the blind ditch to connect all the blind ditches in the post-cast strip. The drain pipe is a square pipe. The drain pipe is set in the form of a filter pipe and wrapped with geotextile.

[0032] During floor construction, the first water diversion pipe and the second water diversion pipe are buried, one end of the first water diversion pipe extends into the water filter pipe and is laid along the bottom plate plane, and the other end of the first water diversion pipe is connected to the water collection well.

[0033] The first water diversion pipe and the second water diversion pipe are buried under the hydrophobic plate. At the same time, the presence of the hydrophobic plate can effectively isolate the water source and keep the bottom plate dry.

[0034] The riverside basement floor pressure relief structure of the utility model can unload water pressure when the building is close to the river and the basement floor is thin and facing rising water level, thereby avoiding floating damage to the basement and protecting people's safety, life and property.

[0035] When the basement water level rises, the water will flow into the drain pipe or filter pipe within the post-cast joint slab, and then be discharged to the sump through the first and second water diversion pipes, thus preventing damage to the base slab. Downward-facing valves can be installed at the other ends of the first and second water diversion pipes to discharge the water uniformly when the water pressure reaches a certain level. The filter pipe can be equipped with a blind plate to weld the top of the filter pipe closed to prevent excessive water pressure from squeezing the drain plate at the filter pipe.

[0036] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
