The invention discloses a support system in a non-prestressed foundation pit and a construction method. The support system is provided with a plurality of support units along the length direction of the foundation pit, and the support units with modular design are used for easy installation and disassembly. Each support unit is provided with two sets of first beams, the close ends of the two sets of first beams are hinged together, and the remote ends contact the purlins on both sides of the foundation pit through the ends, and the two sets of first beams can Gravity decomposes to the upper purlins on both sides of the foundation pit along its own length, and exerts a thrust on the upper purlins on both sides of the foundation pit to form automatic top support. Compared with the traditional prestressed support system, it is more reliable and convenient to use. The construction method is used to construct the foundation pit using the prestressed foundation pit inner support system of the first aspect, which greatly improves the construction progress and reduces the construction cost.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a support system in a non-prestressed foundation pit and a construction method. Background technique [0002] During building construction or municipal engineering construction, it is usually necessary to excavate foundation pits. The foundation pit is a temporary sub-item project whose function is to excavate the bottom space, so that the masonry work of the building foundation can be carried out according to the position specified in the design drawings. Generally speaking, a foundation pit with a depth of more than 5 meters is a deep foundation pit. The excavation of a deep foundation pit is a sub-project with high risk and difficulty. When excavating a deep foundation pit, the construction personnel usually use mixed Soil support, steel structure support or a combination of the two support methods to ensure the protection and safety of the foundation pit. [0003] The e...
