Description

Technical Field

[0001] This utility model relates to the field of foundation pit excavation slope protection technology, and more specifically to a foundation pit excavation slope protection blanket. Background Technology

[0002] With the rapid development of urban construction and the continuous expansion of infrastructure projects, foundation pit excavation is becoming increasingly common in building construction. Foundation pit slope protection, as a crucial measure to ensure construction safety and prevent soil erosion, is of great significance to both project quality and construction safety. However, existing foundation pit slope protection blankets have the following technical problems in practical applications: Existing slope protection blankets have significant shortcomings in terms of stability and long-term reliability. Traditional blankets typically use simple nailing methods, relying solely on surface anchor points for fixation, lacking an effective deep anchoring mechanism. This results in insufficient bonding between the blanket and the ground. During long-term use, especially under the influence of external forces such as rainwater erosion, wind, and ground settlement, the blankets are prone to loosening, displacement, or even detachment, severely impacting slope protection effectiveness. This instability in fixing not only reduces the service life of the blankets but may also cause them to lose their protective function at critical moments, posing a threat to project safety.

[0003] A more prominent problem is that existing protective blankets have serious limitations in terms of interception function and adaptability. The interception structure of traditional protective blankets usually adopts a fixed aperture design, and the size of the holes inside the interception groove cannot be adjusted according to actual needs, resulting in significant differences in the interception effect on soil and stones of different particle sizes. In particular, existing protective blankets often cannot effectively intercept smaller soil particles and fine stones. These fine particles can easily be lost through the holes of the protective blanket, which not only affects slope stability but may also cause soil erosion and environmental pollution. At the same time, the fixed aperture design cannot adapt to the changing needs of different engineering environments and soil conditions, limiting the application range and protective effect of protective blankets.

[0004] In addition, existing protective blankets are inadequate in terms of installation convenience and construction efficiency. The complicated installation procedures and low fixing reliability increase the difficulty and cost of construction, affecting the project progress and construction quality.

[0005] Therefore, there is an urgent need to develop a foundation pit slope protection blanket that can achieve reliable fixation and long-term stable use, as well as flexible interception function and good adaptability, in order to meet the comprehensive requirements of modern foundation pit engineering for safety, reliability and environmental protection. Utility Model Content

[0011] Furthermore, the included angle between two adjacent interceptor plates is 90 degrees, and the included angle between two adjacent interceptor bars is 90 degrees.

[0012] Furthermore, the angle between the intercepting rod and the reinforcing arc tube is forty-five degrees, and the outer side of the intercepting assembly fits into the inner side of the intercepting groove.

[0013] Furthermore, there is a clearance fit between the cross-sectional dimensions of the positioning reinforcement plate and the cross-sectional dimensions of the positioning column, and a clearance fit between the diameter of the bottom of the positioning column and the diameter of the top of the positioning cone.

[0014] The technical effects and advantages of this utility model are as follows: 1. When protecting the slope of a foundation pit, this utility model first lays the equipment on the slope, then nails the positioning column and positioning cone into the ground through the positioning hole, then nails the positioning component in by pressing down the pressure plate, then pushes the second positioning plate down to push the positioning reinforcement plate down, and then the positioning reinforcement plate is inserted into the ground in all directions, thereby increasing the equipment's grip on the ground and preventing the equipment from falling off during long-term use; 2.
