Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, and more specifically, to a groundwater level monitoring device for housing construction projects. Background Art
[0002] During the process of housing construction, groundwater has many important impacts. Firstly, the buoyancy of groundwater may cause the foundation of the building to float, which may further lead to uneven settlement and pose a threat to structural safety. Especially in soft soil foundation areas, it is very likely to cause the building to tilt and crack. Secondly, a high groundwater level will increase the difficulty of foundation construction. When excavating the foundation pit, groundwater will continuously seep into the pit, which is likely to cause problems such as pit wall collapse and base softening, so drainage measures need to be taken. Thirdly, corrosive substances in groundwater will corrode building materials, such as causing the steel bars in concrete to rust, reducing the strength and durability of the materials. Fourthly, in cold regions, the freezing of groundwater will generate frost heaving force, which can damage the foundation and underground structures. Fifthly, groundwater will also reduce the shear strength of the soil mass, affect the stability of the slope, increase the construction safety risk, and make the construction site wet, affecting the safety of construction workers and the operation of equipment. In addition, if the basement or the ground floor of the building is in contact with groundwater, it is easy to appear problems such as dampness and mildew, affecting the use function. At the same time, the change of the groundwater level may also affect the water supply and drainage system, resulting in problems such as sewage backflow and poor drainage.
[0003] To reduce the adverse effects of groundwater on housing construction, corresponding measures are usually taken during the construction process, such as adding anti-floating anchor rods or implementing groundwater dewatering measures. Among them, groundwater dewatering is a crucial construction operation, and its main purpose is to lower the groundwater level to ensure the smooth progress of foundation engineering construction and the stability of the building. However, during the process of groundwater dewatering, there is a serious problem that the groundwater level cannot be effectively monitored. This makes it impossible for construction managers or operation managers after the house is delivered to accurately grasp whether the groundwater level is in a normal state, which may lead to continuous dewatering. If continuous dewatering is carried out, it will generate huge costs, which is obviously not practical. Moreover, long-term excessive dewatering may also damage the surrounding geological environment, affect the ecological balance, and may also cause safety hazards such as ground settlement.
[0004] Therefore, it is extremely urgent to solve the problem of water level monitoring during the process of groundwater dewatering. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a groundwater level monitoring device for housing construction projects, aiming to solve the technical problems in the above background art.

One end of the first water outlet pipe, one end of the second water outlet pipe, and one end of the third water outlet pipe are all independently connected to the drainage pipe. The first water outlet pipe, the second water outlet pipe, and the third water outlet pipe are all arranged outside the foundation trench, and the first water outlet pipe, the second water outlet pipe, and the third water outlet pipe are arranged at intervals in sequence along the axis direction of the drainage pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] Embodiment: Please refer to FIG. 1. An embodiment of the present application provides a groundwater level monitoring device for building construction projects, which is applied to the foundation pit of a building. A foundation trench 100 is provided at the bottom of the foundation pit. A drainage pipe 300 is vertically arranged inside the foundation trench 100. The upper end of the drainage pipe 300 penetrates through the foundation trench 100 and extends into the foundation pit. This vertically arranged drainage pipe 300 has many advantages. On the one hand, it saves the material of the drainage pipe 300 because the vertical arrangement can reduce the length of the pipe on the premise of meeting the functional requirements, which is conducive to reducing the cost of this device. The inside of the foundation trench 100 is filled with gravel to form a filter layer 200 that wraps around the end of the drainage pipe 300. This filter layer 200 can achieve the preliminary filtration of the groundwater entering the drainage pipe 300. In practical applications, the groundwater may contain various impurities. If not filtered, the impurities are likely to block the drainage pipe 300, affecting the normal operation of the monitoring device. By setting the filter layer 200, it can effectively prevent the groundwater containing impurities from blocking the drainage pipe 300, ensuring the reliability and stability of the device. Moreover, choosing gravel to fill the foundation trench 100 has the advantage of low cost, which not only realizes the filtering function but also does not significantly increase the cost of the device.
[0025] A water level warning component 600 is provided on the drainage pipe 300 above the foundation trench 100. The water level warning component 600 includes a first water outlet pipe 601, a second water outlet pipe 602, and a third water outlet pipe 603. One end of the first water outlet pipe 601, one end of the second water outlet pipe 602, and one end of the third water outlet pipe 603 are all independently connected to the drainage pipe 300. These three water outlet pipes are all arranged outside the foundation trench 100 and are arranged at intervals in sequence along the axial direction of the drainage pipe 300. Such a design can judge the height of the groundwater level through the water discharge conditions of different water outlet pipes, providing accurate groundwater level information for building construction projects so as to take corresponding measures in a timely manner.
[0026] The groundwater level monitoring device of the present application has significant advantages in actual use. If the groundwater level rises, the groundwater will first enter the foundation trench 100 and enter the drainage pipe 300 after the initial filtration by the filter layer 200. As the water level changes, when the water level reaches the first water outlet pipe 601, the second water outlet pipe 602, or the third water outlet pipe 603 correspondingly, the groundwater can flow out from the corresponding water outlet pipe, thereby realizing the monitoring of the groundwater level. When the water level exceeds the second water outlet pipe 602, it indicates an emergency, and the foundation pit dewatering can be carried out immediately; when the water level is lower than the first water outlet pipe 601, the dewatering operation can be stopped. Such a design provides accurate data support for the foundation pit dewatering, making the dewatering operation more scientific and reasonable, avoiding unnecessary resource waste and engineering risks, and being more practical in actual applications, providing a strong guarantee for the safety and smooth progress of underground projects.
[0027] In some embodiments of the present utility model, one end of the first water outlet pipe 601 away from the drainage pipe 300, one end of the second water outlet pipe 602 away from the drainage pipe 300, and one end of the third water outlet pipe 603 away from the drainage pipe 300 are all inclined towards the bottom of the foundation pit.
[0028] In the above embodiment, the first water outlet pipe 601, the second water outlet pipe 602, and the third water outlet pipe 603 are arranged in an inclined manner. This design is of great significance. When the water level in the drainage pipe 300 reaches the corresponding water outlet pipe level, it can be discharged in a timely manner from the corresponding water outlet pipe, thereby facilitating the more accurate acquisition of groundwater level information and providing a strong guarantee for the construction and safety of building construction projects.
[0029] In some embodiments of the present utility model, a first warning sign 700, a second warning sign 800, and a third warning sign 900 are provided on the outer side of the drainage pipe 300, and the first warning sign 700, the second warning sign 800, and the third warning sign 900 are respectively horizontally opposite to the first water outlet pipe 601, the second water outlet pipe 602, and the third water outlet pipe 603 one by one.
[0030] In the above embodiment, the first warning sign 700 is horizontally opposite to the first water outlet pipe 601, the second warning sign 800 is horizontally opposite to the second water outlet pipe 602, and the third warning sign 900 is horizontally opposite to the third water outlet pipe 603. Such a setting enables the water level information to be quickly read through these warning signs, providing an intuitive and convenient way for groundwater level monitoring and improving the monitoring efficiency.
[0031] In some embodiments of the present utility model, the first water outlet pipe 601 is arranged close to the foundation trench 100;
[0032] Among them, a filter screen 400 is arranged inside the drainage pipe 300 below the first water outlet pipe 601.
[0033] In the above embodiment, the design of the filter screen 400 plays an important role. It can filter the groundwater entering the inside of the drainage pipe 300 again, thereby improving the filtering effect of the groundwater. Specifically, the filter screen 400 and the filter layer 200 together form a two-stage filtering structure, further enhancing the filtering ability of the groundwater and ensuring the stable operation of the monitoring device.
[0034] In some embodiments of the present utility model, the material of the drainage pipe 300 is PVC material.
[0035] The drainage pipe 300 made of PVC material has many advantages. First of all, the cost of the PVC drainage pipe 300 is relatively low, which is economical and suitable for large-scale applications. Secondly, it has good corrosion resistance and can be used in a variety of different environments without being easily eroded by chemical substances. Moreover, the PVC drainage pipe 300 is light in weight, which is convenient for transportation and installation, reducing the construction difficulty and cost. At the same time, its inner wall is smooth, and the water flow resistance is small, which is beneficial to improving the conveying efficiency of groundwater. In addition, the PVC drainage pipe 300 has certain strength and toughness, can withstand certain pressure and external force impact, and has a long service life.
[0036] In some embodiments of the present invention, a basement floor slab 500 is cast and formed at the bottom of the above foundation pit;
[0037] Among them, the above first water outlet pipe 601, the above second water outlet pipe 602 and the above third water outlet pipe 603 are all located above the above basement floor slab 500.
[0038] In the above embodiment, the basement floor slab 500 is cast and formed by concrete. The first water outlet pipe 601, the second water outlet pipe 602 and the third water outlet pipe 603 are all above the basement floor slab 500. Such a setting is convenient for groundwater level monitoring, enabling the staff to more intuitively observe the water level situation and take corresponding measures in a timely manner.
[0039] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
