Reusable assembled adjustable guide wall inner support frame, and applied construction method thereof
The invention relates to the technical field of building engineering, in particular to reusable assembled adjustable guide wall inner support frame, and applied construction method thereof
With the development of cities, urban land resources become more and more scarce, and the development and utilization of underground space becomes more and more important. As an effective means to realize the development and utilization of underground space, the support requirements of foundation pit are getting higher and higher. Especially in the busy, narrow site, complex geological and hydrological conditions, it is often necessary to use underground diaphragm wall or pile-row wall and other supporting forms. In order to ensure the construction quality of supporting structures such as underground diaphragm wall and row pile wall, it is often necessary to build guide walls at the lower diaphragm wall and row pile wall before construction; The guide wall is generally 1.5m-3m deep,
The internal clear distance is generally 50mm-100mm longer than the thickness of diaphragm wall or the diameter width of supporting pile. Because it is a narrow groove, its safety and stability are often neglected in construction, while the guide wall plays the role of positioning and supporting the static and dynamic loads of construction and guiding the retaining wall mud during the construction of underground diaphragm wall and pile-row wall. Its safety and stability are of great significance to the construction of underground diaphragm wall and pile-row wall. Once it is collapsed or deformed too much, it will have a great impact on the safety of diaphragm walls and pile-row walls and the wall quality, and even have safety accidents such as the overturning of construction equipment affecting the safety of surrounding environment. The inner support structure plays a key role in the safety and stability of the guide wall, however, the prior art mainly uses plain concrete short column support or square timber support as the support frame in the guide wall , which could not be adjusted in time when the guide wall was deformed by dynamic and static loads. It was easy to loose and fall off, and the support failure affected the safety of construction, and it could not be prestressed in advance. Moreover, the support could not be recycled and turned into construction waste after dismantling, thus resulting in waste of resources.
