Problems solved by technology

[0003] Due to factors such as short project time, construction conditions, and reinforcement effects, some commonly used slope treatment technologies and measures are difficult to meet emergency reinforcement requirements.
For example, although the retaining wall technology has the characteristics of low construction cost and convenient material acquisition, its integrity is poor and the reinforcement effect is relatively weak; the anti-slide pile technology has the advantages of flexible pile position layout, strong bearing capacity, and deep reinforcement, but there are Disadvantages such as high cost and long cycle
The soil nailing support technology is to excavate the slope surface of the foundation pit, use mechanical drilling or Luoyang shovel to form holes, put steel bars in the holes, and inject grout, install steel mesh on the slope surface, and spray concrete with a certain thickness to make the soil, Steel bars and shotcrete panels are combined to form a soil retaining structure, but the cement mortar injected at the position where the soil nails are set and the concrete sprayed on the slope still need a certain amount of time before solidification to form sufficient strength, and because the soil nails support Layer-by-layer excavation is generally adopted for protection, and the accumulated construction time is generally long, which affects the application of this technology in emergency reinforcement of slopes.

Embodiment 1

[0050] This embodiment provides a rapid foam filling method for slope emergency reinforcement. The rapid foaming material it belongs to is a polymer foaming material (such as polyurethane, etc.). Include the following steps:

[0051] Step 1: Through on-site inspection of the slope type and engineering geological environment, if the slope is a steep slope, select a higher retaining wall according to relevant specifications, and set the position at the bottom of the slope (see figure 1 ), if the foundation foundation under the retaining wall is average, it needs to be reinforced;

[0052] Step 2: Drill holes horizontally on the slope surface and insert structural reinforcements, then drill holes in the vertical direction and insert anti-rust structural reinforcements. Horizontal structural reinforcements and vertical structural reinforcements are connected with iron wires; structural reinforcements need to be considered The influence of spacing and size; the structural reinfor...

Embodiment 2

[0057] This embodiment provides a rapid foaming filling method for slope emergency reinforcement, such as image 3 shown, including the following steps:

[0058] Step 1: According to the on-site inspection of the slope type and engineering geological environment, the slope is a gentle slope, and the retaining wall is selected according to the relevant specifications, and the position is set at the bottom of the slope (see figure 2 ), if the foundation foundation under the retaining wall is average, it needs to be reinforced.

[0059] Specifically, the on-site engineering geological information includes the engineering geological environment, the type, location, area, thickness, and degree of danger of the slope; methods for obtaining the on-site engineering geological information include: on-site investigation, on-site survey, and consulting relevant materials.

[0060] The relevant specifications referred to in this embodiment include: "Code for Design of Building Foundatio...

Abstract

The invention discloses a rapid foaming and filling method for emergency reinforcement of a side slope. A rapid foaming and filling material is a polymer foaming material such as polyurethane. A polymer foaming material is rapidly sprayed between the side slope retaining wall and the side slope through a high-pressure spraying device, and high strength is formed within a short time; and finally, a structural material with the structural ribs as a framework and the polymer foaming material as a base body is formed, the structural material, the wall body and the side slope form a whole, and therefore the safety and stability of the side slope are improved.

Description

technical field [0001] The invention belongs to the technical field of slope disease control in civil engineering, and in particular relates to a rapid foaming and filling method for emergency reinforcement of slopes. Background technique [0002] Due to geological movement, weather disasters, artificial activities and other factors, slope diseases occur from time to time. Due to emergency needs such as rescue and emergency missions and road protection, some slope diseases need to be treated quickly and promptly, that is, emergency reinforcement of the slope to ensure that the slope will not experience serious slippage in a short period of time. [0003] Due to factors such as short project time, construction conditions, and reinforcement effects, some commonly used slope treatment technologies and measures are difficult to meet the emergency reinforcement requirements. For example, although the retaining wall technology has the characteristics of low construction cost and ...
