Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a foundation pit support structure for building engineering. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plan dimensions. Before excavation, an excavation plan should be determined based on geological and hydrological data and the condition of nearby buildings, and waterproofing and drainage work should be carried out. For shallow excavations, slope protection can be used to stabilize the soil slope, and the slope should be determined according to relevant construction regulations. For deeper excavations or those near buildings, excavation pit wall support methods, shotcrete wall protection methods, and even methods such as diaphragm walls and interlocking column-type bored piles can be used to prevent the outer soil layer from collapsing. For excavations without the influence of nearby buildings, the wellpoint method can be used to lower the groundwater level, and open excavation with slope protection can be adopted. In cold regions, natural freezing methods can be used for excavation, etc.

[0031] In this embodiment, when in use: a suitable abutment plate 111 can be installed before the foundation pit support. The limiting hole at the bottom of the abutment plate 111 is aligned with the positioning seat 12, and then placed on the top of the mounting base 18. At the same time, the bidirectional screw 17 is rotated to bring the two sets of clamping plates 14 closer to each other. Meanwhile, the clamping block 13 is inserted into the positioning hole inside the abutment plate 111 to limit its position, ensuring the convenience and firmness of the abutment plate 111 installation and improving the equipment's performance.

[0032] After the abutment plate 111 is installed, the height of the adjusting plate 113 can be adjusted. When moved upward, the adjusting plate 113 can be pulled directly upward along the inside of the abutment plate 111. At the same time, the limiting spring 112 repeatedly compresses and resets, so that the one-way locking tooth 115 can be stably inserted into the inside of the abutment plate 111 to fix the adjusting plate 113. When it is necessary to put the adjusting plate 113 back in, pull the pull rod 116 to drive the limiting spring 112 to be compressed, so that the one-way locking tooth 115 disengages from the inner wall of the abutment plate 111. At this time, the adjusting plate 113 can be put back into the inside of the abutment plate 111, ensuring the convenience of equipment use and reducing the cost of use.
