Embodiment 1

[0036] see Figure 1-6 , a municipal engineering foundation pit safety protection device, comprising a foundation pit support frame 1, a support mechanism 3 located in the foundation pit support frame 1 and a bearing portion 4 located on the support mechanism 3, the lower part of the support mechanism 3 and the foundation pit support frame 1. The inner side is elastically matched. Specifically, the foundation pit support frame 1 includes two baffle plates 11, a support column 12 located between the two baffle plates 11, and a guide plate 13 sleeved through the support column 12. The two guide plates 13 is used in conjunction with two support mechanisms 3, the support mechanism 3 includes two steady state support assemblies 31 and a pallet 32 ​​at the top of the steady state support assemblies 31, wherein the steady state support assemblies 31 play a supporting role, which includes an X-shaped The bracket 311 and the stabilizing mechanism 312 located on the upper part of the br...

Embodiment 2

[0038] see Figure 4 and Image 6, and the difference from Embodiment 1 is that the bearing part 4 includes a magnetic combination 43, the magnetic combination 43 is located between the bearing plate 41 and the reinforcing frame 42, the guide post 422 is sleeved with a return spring 2, and the return spring 2 is located in the bearing plate 42. Below the plate 41, the magnetic-movement combination 43 includes an electromagnetic plate 431 and a floating magnetic plate 432. The electromagnetic plate 431 is located in the carrier plate 41. The top is fixedly provided with a resistance-increasing plate 4221, and the resistance-increasing plate 4221 is used to increase the friction force with the logistics tool. Therefore, when the electromagnetic plate 431 is powered off, the guide column 422 is pushed down under the tension of the return spring 2, and then The entire reinforcing frame 42 is located below the carrying plate 41. When the electromagnetic plate 431 is energized, a m...

Abstract

The invention discloses a foundation pit safety protection device for municipal engineering, which comprises a foundation pit support frame, a support mechanism located in the foundation pit support frame and a bearing part located on the support mechanism, and the two ends of the support mechanism are close to the lower part and the foundation pit The two sides in the support frame are elastically matched, and the support mechanism includes two stable support combinations and a supporting plate at the top of the stable support combination. In the present invention, the protection of the foundation pit is realized by setting the stable support combination and the bearing part on the support frame of the foundation pit, and at the same time, it is convenient for the logistics tools to pass above the foundation pit to reduce the logistics pressure, wherein the bearing part is used to support the logistics vehicle , the support mechanism plays a role in stabilizing the buffering of the bearing part, and can buffer in the horizontal direction or in the vertical direction, thereby not only playing the role of protecting the foundation pit, but also facilitating the passage of logistics tools.

Description

technical field [0001] The invention relates to the technical field of municipal foundation pit protection, in particular to a municipal engineering foundation pit safety protection device. Background technique [0002] The buildings in the central urban area are becoming more and more dense, especially the large number of new high-rise and super high-rise buildings. The construction of municipal roads requires digging a large number of deep foundation pits. The foundation pit protection device is a support, reinforcement and protection measure for the side walls of the foundation pit and the surrounding environment to ensure the safety of the construction of the underground structure and the surrounding environment of the foundation pit. [0003] Most of the existing foundation pit protection devices use a pile support structure. By setting baffles to fit the two sides of the foundation pit, and then using support columns to support the baffles, the baffles press the inner ...
