Embodiment

[0020] Such as figure 1 , 2 As shown, a foundation pit protection support with high safety performance includes a protection base 5 with a concave-shaped cross section and close to the surface of the foundation pit, two pressing devices 3, respectively arranged on the protrusions at both ends of the protection base, The monitoring control system 2 and the protective net 8 used to monitor the state of the foundation pit and control the pressing device in real time according to the monitoring results. The pressing device is electrically connected to the monitoring control system. A pressing rod 9 is arranged between the pressing devices to monitor The control system is set on the foundation pit. The monitoring and control system can monitor the actual soil pressure of the foundation pit in real time, and can calculate the balance force to be output according to the measured soil pressure. At least one protective bracket is set on the protective base The protective base is made of ...

Abstract

The invention relates to the technical field of construction, in particular to a high-safety foundation pit protection bracket. The high-safety foundation pit protection bracket comprises a protectionbase with the cross section of a concave-shaped structure and tightly attached to the surface of a foundation pit, two pressing devices arranged on protrusions at the two ends of the protection base,monitoring control systems for monitoring the state of the foundation pit and controlling the pressing devices in real time according to the monitoring result and protection nets. The pressing devices are electrically connected with the monitoring control systems. A pressing rod is arranged between the pressing devices. The monitoring control systems are arranged on the foundation pit. Protectionbracket assemblies are arranged on the protection base. Each protection bracket assembly comprises a protection frame, support rods and a stress rod. Rod penetrating holes allowing the pressing rod to penetrate are formed in the ends, away from the support rods, of the stress rods. A protection net groove allowing the corresponding protection net to be inserted therein is formed in the inner sideof each protection frame. The high-safety foundation pit protection bracket is simple in structure, easy to mount and dismount, capable of being reused, good in stability and high in safety.

Description

Technical field [0001] The invention relates to the field of construction technology, in particular to a foundation pit protection bracket with high safety performance. Background technique [0002] Foundation pit is a soil pit excavated at the design position of the foundation according to the elevation of the foundation and the plane size of the foundation. The foundation pit is a temporary project, and its function is to provide a space so that the masonry work of the foundation can be carried out according to the position specified by the design. [0003] Common types of foundation pit support mainly include: 1. Row pile support, pile support, pile anchor, row pile cantilever; 2. Underground continuous wall support, ground connecting wall + support; 3. Cement retaining wall; 4. Steel sheet pile: profiled steel pile horizontal baffle support, steel sheet pile support; 5. Soil nail wall (spray-anchor support); 6. Reversed arch wall; 7. Undisturbed soil grading; 8. Foundation pit ...
