[0002] The engineering foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions, so as to facilitate the laying of underground pipelines and installation of underground equipment in the foundation pit. However, after the excavation of the engineering foundation pit, the soil in the foundation pit is prone to collapse, affecting safety, so the excavated engineering foundation pit needs to be reinforced and supported.

[0003] The Chinese patent discloses a foundation pit reinforcement support device (authorization announcement number CN212835430U). The patented technology is provided with reinforcement holes, reinforcement rubber rings and reinforcement nails. During the use of the support device, the connection between the entire support device and the lower end ground is more stable through the newly added reinforcement holes and the fixation of the reinforcement nails. The arrangement of the reinforcement rubber ring makes the connection between the reinforcement nails and the connection base tighter, and the overall stability of the device is better. By providing an oblique bracket, a No. 1 reinforcement bracket and a No. 2 reinforcement bracket, during the installation of the support device, the oblique arrangement of the oblique bracket forms a stable triangular connection between it and the steel baffle and the connection base. The No. 1 reinforcement bracket reinforces and divides the formed triangle into two triangular connections again. Similarly, the No. 2 reinforcement bracket further strengthens the connection stability, so that the stability of the steel baffle is better, and the entire device is not easy to roll over and has better safety. The entire foundation pit reinforcement support device has a simple structure, is easy to install, has strong safety, is extremely stable, and has a good use effect.
