Description

Supporting template for absorbing water seepage of side wall of foundation pit

Technical Field

The utility model relates to the field of foundation pit support, in particular to a support template for absorbing water seepage of the side wall of a foundation pit.

Background

Underground foundation pit excavation is very common in modern construction engineering. However, this process is often accompanied by problems with water seepage from the pit side walls. This problem is not only a technical challenge in construction, but may also lead to a reduced stability of the foundation pit side walls. Meanwhile, the seepage water is accumulated at the bottom of the foundation pit, so that the soil at the bottom of the foundation pit becomes wet and loose, and the stability of the foundation is reduced.

Conventional well-point precipitation is common in foundation pit precipitation, but has a number of disadvantages. First, it is difficult to quickly lower the ground water level of the entire foundation pit, especially for large foundation pits, with relatively low efficiency. In addition, running well-point precipitation equipment requires a large amount of energy, which may increase the energy costs of long-term construction. The slow precipitation at well points, especially at high water levels, may lead to delays in construction. Meanwhile, the discharge of sediment and pollutants contained in groundwater may pose a potential threat to the environment and groundwater quality. Moreover, well-point precipitation needs to be continuously monitored and maintained, and operation and maintenance cost and labor investment are increased. Well-point precipitation may also cause site water to accumulate, increase safety risks to workers, and potentially impact surrounding traffic.

Therefore, the utility model provides the supporting template for absorbing water seepage on the side wall of the foundation pit, which can effectively reduce the use of well-point precipitation.
