Technical Field

[0001] This utility model relates to the field of pressure relief and drainage technology, and in particular to a construction node for pressure relief well pipe connection for water intake and pressure relief. Background Technology

[0002] The construction background of pressure relief well connection for water diversion and pressure relief is closely related to the control of confined water, structural safety protection and complex hydrogeological conditions in underground engineering.

[0003] A search revealed Chinese patent CN218373965U, which discloses a pressure relief well self-drainage system, including a pre-embedded pipe positioned below a raft foundation. One end of the pre-embedded pipe is connected to the pressure relief well, and the other end is connected to a collection well. A concrete protective layer is provided at the upper end of the pre-embedded pipe, and a cushion layer is provided between the concrete protective layer and the raft foundation. This invention reduces the need for subsequent manpower and material investment and features simple and rapid construction.

[0004] Based on the above retrieval methods combined with existing technologies;

[0005] The pressure relief wells in the aforementioned patents are exposed to the outside of the basement for a long time. During the flood season, a large amount of groundwater flows out through the pressure relief wells, resulting in water accumulation in the basement. The construction is not civilized. In addition, some pressure relief wells are located on the main route of the basement construction road. Due to the lack of finished protection measures for the pressure relief wells, they are damaged. Therefore, there are certain limitations. Utility Model Content

[0006] To address the aforementioned technical issues, this utility model proposes a construction node for water intake and pressure relief in a pressure relief well connection, which promotes the effective development of construction and has significant economic and social benefits.

[0007] The technical solution to achieve the purpose of this utility model is: a pressure relief well pipe connection construction node for water intake and pressure relief, including a base plate, and also including;

[0008] Well casing, which is fixedly connected to the inside of the base plate;

[0009] A water collection pit is fixedly installed on one side of the base plate, and a water pump is fixedly installed inside the water collection pit.

[0010] Preferably, a steel pipe is fixedly connected inside the well pipe, one end of the steel pipe passes through the bottom plate and is set inside the sump, an automatic float valve is installed on the steel pipe, a steel plate is welded inside the well pipe, and the other end of the steel pipe passes through the steel plate.

[0011] Preferably, the well pipe is provided with slurry, the slurry is placed on the top of the steel plate, a sand and gravel filter screen is fixedly installed near the bottom of the well pipe, and an annular water-stop plate is fixedly installed on the well pipe.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model uses a pressure relief well to connect the water inlet and pressure relief node, which can effectively improve the level of civilized construction of the basement and reduce the accumulation of water in the basement during the flood season due to seepage from the pressure relief well. In addition, the concealed pressure relief well can reduce the damage to the pressure relief well on site during construction and improve the pressure relief efficiency.

[0014] Secondly, the automatic float valve and water-stop ring in this utility model improve the practicality of the node. The automatic float valve has an automatic response mechanism, a durable structural design, and adaptability to complex working conditions during the pressure relief process. This construction node can promote the effective development of construction and has very strong economic and social benefits for current construction.

[0015] This solution addresses the problems of existing pressure relief wells being exposed to the outside of the basement slab for extended periods, leading to a large outflow of groundwater during the flood season, resulting in water accumulation in the basement and poor construction practices. Additionally, some pressure relief wells are located on the main construction route of the basement, and the lack of protective measures for the finished products of these wells has led to their damage.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved construction node for a pressure relief well connection for water intake and pressure relief. The technical solution of this utility model is as follows:

[0024] Example 1

[0025] like Figure 1 As shown, it includes a base plate 1, which provides excellent support for construction on site, and also includes;

[0026] Well pipe 2 is fixedly connected to the inside of the base plate 1 and is opened on the inner side of the base plate 1 to facilitate drainage and improve pressure relief efficiency.

[0027] The water collection pit 3 is fixedly installed on one side of the base plate 1. A water pump 10 is fixedly installed inside the water collection pit 3, which effectively improves the level of civilized construction of the basement and reduces water accumulation in the basement due to seepage from the pressure relief well during the flood season.

[0028] Example 2:

[0029] Based on the pressure relief well connection and water inlet / pressure relief construction node provided in the first embodiment of this application, the second embodiment of this application proposes another pressure relief well connection and water inlet / pressure relief construction node. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0030] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0031] like Figure 2-3 As shown, a steel pipe 6 is fixedly connected inside the well pipe 2. One end of the steel pipe 6 passes through the bottom plate 1 and is set inside the sump 3. An automatic float valve 4 is installed on the steel pipe 6. A steel plate 7 is welded inside the well pipe 2. The other end of the steel pipe 6 passes through the steel plate 7. The automatic float valve 4 can respond quickly when the liquid level changes or the pressure is abnormal through the float linkage mechanism. It does not require external energy to drive and relies on the buoyancy of the medium itself to achieve control, thus reducing energy consumption.

[0032] Furthermore, the well pipe 2 is equipped with slurry 9, which is placed on top of the steel plate 7. A sand and gravel filter screen 8 is fixedly installed near the bottom of the well pipe 2, and an annular water-stop plate 5 is fixedly installed on the well pipe 2. The synergistic application of the annular water-stop plate 5 and the well pipe 2 is the core strategy for waterproofing underground engineering. The water-stop plate achieves physical water blocking through material properties and structural design, while the well pipe 2 reduces water pressure through active drainage. The combination of the two can cope with complex hydrogeological conditions.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
