Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to an automatic control device for preventing overpressure leakage in a basement. Background Art

[0002] In the field of construction engineering, effective control of groundwater pressure is of great significance. If the groundwater pressure is not properly controlled, it will cause serious problems such as deformation of the building foundation and leakage in the basement, which will greatly affect the safety and durability of the building. The deformation of the building foundation threatens the stability and use function of the structure, and the leakage in the basement will damage the internal environment and may damage the stored items. In the construction of basement projects, the waterproof performance of the floor structure is crucial. Due to the influence of various factors such as groundwater pressure, concrete structural defects and construction technology, leakage problems in the basement floor occur from time to time, which seriously affects the normal use function of the basement and may threaten the durability of the building. Traditional leakage detection and repair methods have certain limitations. In order to more effectively prevent and solve the problem of basement floor leakage, a method is now invented that can automatically control and adjust the damage of the basement floor to the groundwater pressure.

[0003] At present, in conventional basement construction, the groundwater level is controlled by means of drainage pipes and wells to facilitate safety issues during the basement structure construction. When the basement structure construction is completed, the drainage pipes and wells will be closed. The groundwater level will change with the passage of time. The load borne by the structure during use or the structure itself will be deformed due to changes in the environment and seasons, which may cause certain cracks in the structure and cause leakage. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide an automatic control device for overpressure and anti-leakage in basements. By setting up a device that can automatically discharge and reduce the pressure when the groundwater pressure changes and increases, the problem that traditional devices may cause certain cracks in the structure and cause leakage can be solved.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The invention discloses an automatic control device for overpressure leakage prevention in a basement, comprising a base plate, and also comprising: a downdraft well arranged below the base plate, an overpressure drain pipe being arranged on one side of the downdraft well below the base plate, a water collecting well being arranged at the drainage end of the overpressure drain pipe, the overpressure drain pipe extending into the water collecting well, and a threaded connector being fixedly connected at the end thereof, an overpressure drain valve being threadedly connected to the threaded connector, and when the pressure in the downdraft well below the base plate is too high, water can be automatically drained through the overpressure drain valve at one end of the overpressure drain pipe, thereby reducing the penetration damage to the base plate caused by the groundwater pressure.

[0007] As a preferred technical solution of the present invention, the overpressure drain valve includes a mounting tube, to which an adjusting cylinder is fixedly connected, a valve plate is fixedly connected inside the mounting tube, a water outlet is provided on the valve plate, a valve stem is slidably arranged on the water outlet of the valve plate, a valve stem head is fixedly connected to the top of the valve stem, a sealing sleeve is fixedly sleeved on the valve stem below the valve stem head, and the sealing sleeve is sleeved on the valve stem and placed on the water outlet to achieve sealing.

[0008] As a preferred technical solution of the present invention, an elastic plate is fixedly sleeved on the valve stem, and both ends of the elastic plate are fixedly connected to the inner wall of the mounting tube.

[0009] As a preferred technical solution of the present invention, the mounting tube is fixedly connected to the adjusting cylinder, the adjusting column is arranged through a thread on the top wall of the adjusting cylinder, a lifting plate is arranged at the bottom of the adjusting column, the lifting plate is rotatably connected to the adjusting column, the lifting plate is in sliding contact with the side wall of the adjusting cylinder, the bottom of the lifting plate is fixedly connected to the pressure column, an elastic support member is sleeved on the pressure column, the bottom of the elastic support member is fixedly connected to the pressure plate, and the pressure plate and the valve stem head are arranged correspondingly.

[0010] As a preferred technical solution of the present invention, the overpressure drain pipe is pre-buried in a downcomer well below the bottom plate.

[0011] The present invention has the following benefits: when the device is actually used, when the water level in the downdraft well below the base plate is high, the water can be conducted to the water collection well under the action of the overpressure drain pipe; because of the overpressure drain valve at the end of the overpressure drain pipe, when the water pressure is too high, the pressure generated by the water pressure is high, and when it exceeds the maximum sealing value of the overpressure drain valve, the water in the downdraft well will be discharged into the water collection well through the overpressure drain valve; the above-mentioned device realizes automatic drainage according to the water pressure, thereby effectively reducing the penetration damage of the base plate to the groundwater pressure.

DETAILED DESCRIPTION

[0015] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] Example 1, please refer to Figure 1-Figure 2 The basement overpressure anti-leakage automatic control device comprises a bottom plate 1, and also comprises: a downdraft well 2 arranged below the bottom plate 1, an overpressure drain pipe 3 is arranged on one side of the downdraft well 2 below the bottom plate 1, the water inlet end of the overpressure drain pipe 3 extends to the inside of the downdraft well 2, a water collection well 5 is arranged at the drainage end of the overpressure drain pipe 3, the overpressure drain pipe 3 extends into the water collection well 5, and the end is fixedly connected to a threaded connector 4, an overpressure drain valve 6 is threadedly connected to the threaded connector 4, when the pressure in the downdraft well 2 under the bottom plate 1 is too high, water can be automatically drained through the overpressure drain valve 6 at one end of the overpressure drain pipe 3, thereby reducing the penetration damage of the bottom plate 1 by the groundwater pressure;

[0017] When this embodiment is actually used, when the water level in the downdraft well 2 below the base plate 1 is high, the water can be conducted to the collection well 5 under the action of the overpressure drain pipe 3. Due to the action of the overpressure drain valve 6 at the end of the overpressure drain pipe 3, when the water pressure is too high, the pressure generated by the water pressure is high. When it exceeds the maximum blocking value of the overpressure drain valve 6, the water in the downdraft well 2 will be discharged into the collection well 5 through the overpressure drain valve 6. The above-mentioned device realizes automatic drainage according to the water pressure, thereby effectively reducing the penetration damage of the groundwater pressure to the base plate 1.

[0018] Example 2, please refer to Figure 1-Figure 2 The overpressure drain valve 6 includes a mounting tube 18, to which a regulating tube 10 is fixedly connected, a valve plate 15 is fixedly connected inside the mounting tube 18, a water port 19 is provided on the valve plate 15, a valve stem 7 is slidably provided through the water port 19 of the valve plate 15, a valve stem head 16 is fixedly connected to the top of the valve stem 7, a sealing sleeve 8 is fixedly sleeved on the valve stem 7 below the valve stem head 16, the sealing sleeve 8 is sleeved on the valve stem 7 and placed on the water port 19 to achieve sealing; an elastic plate 17 is fixedly sleeved on the valve stem 7, and both ends of the elastic plate 17 are fixedly connected to the inner wall of the mounting tube 18;

[0019] During actual use, under the action of the overpressure drain pipe 3, the water in the downdraft well 2 will enter the installation pipe 18. When the water pressure is too high, the valve stem head 16 will be driven to rise, and the valve stem head 16 will drive the valve stem 7 to rise, and then the sealing sleeve 8 will rise to above the water opening 19. At this time, the water in the downdraft well 2 will pass through the water opening 19 of the overpressure drain valve 6 and be discharged into the water collection well 5, realizing drainage and pressure relief, thereby reducing the penetration and damage of the groundwater pressure to the base plate 1.

[0020] The adjusting cylinder 10 is fixedly connected to the mounting tube 18, and an adjusting column 12 is provided on the top wall of the adjusting cylinder 10 through a thread. A lifting plate 13 is provided at the bottom of the adjusting column 12, and the lifting plate 13 is rotatably connected to the adjusting column 12, and the lifting plate 13 is in sliding contact with the side wall of the adjusting cylinder 10, and the bottom of the lifting plate 13 is fixedly connected to the pressure column 11, and an elastic support member 9 is sleeved on the pressure column 11, and the bottom of the elastic support member 9 is fixedly connected to the pressure plate 14, and the pressure plate 14 is correspondingly arranged with the valve stem head 16; when actually used, the maximum water discharge pressure can be adjusted according to actual use requirements. The operator only needs to drive the lifting plate 13 to move up and down by rotating the adjusting column 12, and the lifting plate 13 will drive the elastic support member 9 to expand and contract. When the elastic support member 9 expands and contracts, the pressure applied to the pressure plate 14 will increase or decrease accordingly, thereby realizing the adjustment of the maximum drainage pressure of the overpressure drain valve 6, so that the device can adapt to different use requirements and be more flexible to use.

[0021] The overpressure drain pipe 3 is pre-buried in the downdraft pipe well 2 below the base plate 1. Before closing the pipe well, a pipeline is pre-buried near the downdraft pipe well 2 below the base plate 1. An overpressure drain valve 6 is installed in the water collection well 5. When the pressure under the base plate 1 is too high, water can be automatically drained, thereby reducing the penetration damage of the groundwater pressure to the base plate 1.

[0022] The actual use principle of the device is that during the construction of the basement floor 1, a pre-buried pipe is installed on the drainage pipe well 2 of the underground drainage process to the water collection well 5. When the groundwater pressure exceeds the pressure, the water can be automatically discharged through an overpressure drain valve 6 installed in the water collection well 5. At the same time, according to the actual drainage needs, the overpressure drain valve 6 can flexibly adjust the maximum drainage pressure. At the same time, after the drainage is completed, the overpressure drain valve 6 will automatically close. Through this device, when the change of groundwater pressure increases, the device can automatically discharge and reduce the pressure, and the basement floor 1 is safe and will not produce cracks or leakage.
