Problems solved by technology

[0002] The foundation pit support structure and foundation pit support components are the general term for the components or other measures taken to support, strengthen or cover the surrounding rock for the stability and construction safety of the underground chamber after excavation, while the existing foundation pit support When the mechanism is in use, due to construction on the top of the foundation pit, rocks and soil often fall on the foundation pit support mechanism, causing impact on the foundation pit support mechanism, and serious cases may cause damage to the support mechanism Or unstable, and the falling rocks and soil will accumulate on the support mechanism and the position where the support mechanism connects with the foundation pit wall, which is inconvenient to clean. The pressure seriously affects the firmness of the supporting mechanism

Embodiment 1

[0042] like Figure 1-Figure 10 shown:

[0043] A foundation pit supporting and preventing rockfall and soil blocking mechanism for construction engineering, comprising a foundation pit wall 10 and a supporting mechanism 20 supported on the side of the foundation pit wall 10, the supporting mechanism 20 includes a supporting protection component 30, a rockfall protection assembly 40, discharge assembly 50, rockfall collecting assembly 60 and cleaning assembly 70;

[0044] The rockfall protection component 40 is connected to the top of the support protection component 30, the discharge component 50 is connected to one side of the rockfall protection component 40, and the rockfall collection component 60 is connected to the bottom end of the discharge component 50 through the discharge pipeline 54, and the rockfall collects The assembly 60 is disposed at the bottom of the support and protection assembly 30 , and a cleaning assembly 70 is disposed at the bottom of the rockfall c...

Embodiment 2

[0066] like Figure 1-Figure 11 As shown, on the basis of Embodiment 1, multiple supporting mechanisms 20 are connected together through splicing components in turn, which can play a supporting role for the entire foundation pit, so that the top of the entire foundation pit has a shield against falling rocks and falling soil. effect.

[0067] In an optional embodiment, the splicing assembly includes a plurality of connecting plates and fixing screws, and the fixing screws pass through both ends of the connecting plates. Connecting holes are provided on both sides of the bottom plate 31 and the retaining plate 33, and both ends of the connecting plate are provided with connecting holes. It is embedded in the bottom and side walls of the foundation pit through fixing screws through the connecting holes.

[0068] In this embodiment: when in use, the bottom plates 31 and the retaining plates 33 of the plurality of supporting mechanisms 20 are aligned and connected in sequence, an...

Abstract

The invention belongs to the technical field of foundation pit supporting, and particularly relates to a foundation pit supporting rock and soil falling prevention shielding mechanism for constructional engineering, which comprises a foundation pit wall and a supporting mechanism supported on the side surface of the foundation pit wall, and the supporting mechanism comprises a supporting protection assembly, a rock falling protection assembly, a discharging assembly, a rock falling collection assembly and a cleaning assembly. The top of the supporting protection assembly is connected with the rockfall protection assembly, one side of the rockfall protection assembly is connected with the discharging assembly, and through cooperation of the rockfall protection assembly and the discharging assembly, falling impact of gravel soil blocks can be buffered, rockfall can be shielded, and the rockfall is prevented from falling into a foundation pit; falling rocks are dredged to the two sides through the discharging assembly and then fall into the falling rock collecting assembly through the discharging pipeline to be collected, concentrated cleaning is facilitated, meanwhile, falling falling rocks and falling soil are prevented from being accumulated at the top of the supporting mechanism, the bearing pressure of the supporting mechanism is effectively relieved, and the supporting firmness of the supporting mechanism is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of foundation pit support, and in particular relates to a foundation pit support, rockfall and soil shielding mechanism for construction engineering. Background technique [0002] The foundation pit supporting structure and foundation pit supporting components are the general term for the components or other measures taken to support, strengthen or cover the surrounding rock for the stability and construction safety of the underground chamber after excavation. When the mechanism is in use, due to the construction on the top of the foundation pit, falling rocks and soil often fall on the foundation pit supporting mechanism, causing impact to the foundation pit supporting mechanism. In severe cases, the supporting mechanism may be damaged. or unstable, and the falling rocks and soil will accumulate on the support mechanism and the position where the support mechanism and the foundation pit wall are connected, ...
