Problems solved by technology
However, in the actual foundation pit construction, there is a certain deviation between the actual width of each position and the design. In order to eliminate this deviation, some steel plates are usually processed and plugged into the two ends of the inner support to eliminate the error. However, the above support structure It is inconvenient to install and dismantle, and the structure is not well stressed
[0003] At present, some units have adopted the method of setting jacks at both ends of the inner support to adjust the length of the support, but the stability of the jack during the construction process is insufficient, and the long-term support may fail, resulting in the failure of the inner support and causing the entire foundation pit to become unstable. with disastrous consequences

The invention relates to an inner support adjusting structure for a foundation pit support. The inner support adjusting structure comprises a first connecting plate, a second connecting plate, two electromagnets and a positioning plate, wherein the first connecting plate can be installed at one end of a first inner support, two limiting plates are installed on the side, away from the first inner support, of the first connecting plate in an up-down spaced mode, and one end of each limiting plate is rotationally installed on the first connecting plate; the second connecting plate and the first connecting plate are oppositely arranged left and right, and the second connecting plate can be installed at one end of an adjacent second inner support; the two electromagnets are installed on the other sides of the limiting plates in a one-to-one correspondence mode; and the positioning plate is installed between the two limiting plates, and the positioning plate can extend out of the position between the limiting plates in a one-way mode and abut against the second connecting plate. According to the adjusting structure, the strength and rigidity of the structure are improved through mutual occlusion stress of the limiting plates and the positioning plate.
Description
technical field [0001] The invention relates to the technical field of foundation pit construction, in particular to an inner support adjustment structure for foundation pit support. Background technique [0002] At this stage, when carrying out the construction of the internal support of the foundation pit, the material is usually cut in advance according to the design requirements to make a certain length of internal support. However, in the actual foundation pit construction, there is a certain deviation between the actual width of each position and the design. In order to eliminate this deviation, some steel plates are usually processed and plugged into the two ends of the inner support to eliminate the error. However, the above support structure It is inconvenient to install and dismantle, and the structure is not well stressed. [0003] At present, some units have adopted the method of setting jacks at both ends of the inner support to adjust the length of the support...
