Description

Technical Field

[0001] The present invention relates to the technical field of foundation pit water retaining platforms, and particularly relates to a reusable foundation pit water retaining platform and a using method thereof. Background Art

[0002] With the rapid development of the construction industry, large-scale foundation pit projects are increasing day by day. A water retaining platform needs to be set around the foundation pit to prevent surrounding rainwater, etc. from flowing into the foundation pit, causing the foundation pit to be soaked by rainwater, resulting in slope instability and affecting the construction progress.

[0003] The existing water retaining platforms generally use brick masonry for construction and then plaster the outer side. The following problems exist:

[0004] 1. Labor-consuming: The construction and maintenance of the foundation pit water retaining platform consume a large amount of labor. Workers need to perform complex operations such as formwork support, pouring, and reinforcement. The quality of the water retaining platform directly affects the safety of the foundation pit. Workers need to conduct frequent inspections and maintenance, with high labor intensity. Improving efficiency and optimizing processes are the keys to reducing labor consumption.

[0005] 2. Long construction period: Firstly, due to complex geological conditions, there are significant differences in soil quality and groundwater levels in different strata, and the construction of the water retaining platform needs to be adjusted according to specific geological conditions. Secondly, the processes are cumbersome. The construction of the water retaining platform involves multiple processes such as formwork installation, steel bar binding, and concrete pouring. Each process needs to strictly control the quality, which takes a long time.

[0006] 3. Material waste: Firstly, measurement and formwork installation during the construction process may have errors, resulting in concrete pouring exceeding the design scope, forming unnecessary concrete parts. Secondly, the operation skills and experience levels of construction workers will also affect the utilization rate of concrete. If processes such as vibration and plastering are not properly controlled, the concrete surface may be uneven, requiring additional materials for repair. In addition, if the material management at the construction site is not strict, such as waste during the processes of concrete mixing, transportation, and pouring, and the failure to timely handle and recycle waste concrete, it will further exacerbate the material waste problem.

[0007] 4. Difficult to turnover: Firstly, the structural design and dimensions of the water retaining platform are often customized according to the actual situation of a specific foundation pit, which makes its generality and standardization degree relatively low, and it is difficult to directly turnover and use between different projects. Secondly, during the construction process, the water retaining platform may be damaged or deformed due to geological conditions, environmental factors, or construction errors, and it needs to be repaired or adjusted before it can be used again, which increases the difficulty and cost of turnover. In addition, the storage and management conditions at the construction site may also affect the turnover efficiency of the water retaining platform. For example, insufficient storage space and inadequate protection measures may cause the water retaining platform to be damaged or the use to be delayed during the turnover process.

[0008] In view of the deficiencies of the above-mentioned existing technologies, the present invention hereby provides a reusable foundation pit water retaining platform and its usage method to solve the many problems existing in the above-mentioned traditional water retaining platforms.
