Abstract

The utility model provides a prevent stone slope protection structure that freeze damage damaged, includes the soil bank protection, the domatic mound of soil bank protection goes up the rampart and builds the bold stone, forms the bold stone and protects the body at soil bank protection profile of face, and the bold stone protects the body and exceeds ice cover 3-5m along domatic direction, and the lower part extends to submarine toe, and the toe of the bold stone protects the body is bold stone basis, and the bold stone protects the body and be the bold stone step above the bold stone basis and at the thick half department of ice cover, and bold stone step appearance is the thorn shape outward of edges and corners, is the stone slope protection body above the bold stone step. When the ice cover of the reservoir and the lake in the season freezing area extrudes the large stone protective body due to frost heaving, the reaction force generated by the high-strength hard large stone step on the ice cover shears the split ice cover, and the thrust is weakened or eliminated; meanwhile, edges and corners at each position of the large stone body protecting surface split the ice cover, so that the freezing thrust of the ice cover is further weakened. The ice cover thrust which is continuously increased in winter is eliminated under the continuous shearing and splitting of the large stone protective body until the ice cover is unfrozen in spring warm.

Description

Prevent stone slope protection structure of frostbite damage

Technical Field

The utility model belongs to the technical field of building engineering, concretely relates to prevent stone slope protection structure of frostbite damage.

Background

At present, in domestic coastal water slope protection projects of reservoirs and lakes in freezing areas, frost damage such as slope surface collapse, water and soil loss, water pollution and the like is generated due to the pushing of ice thrust of ice covers in winter, and the project belongs to high frost damage. The traditional disposal method is a recovery measure for dredging, discharging pollution, refilling soil and fixing slope to collapse, water loss and soil, and water pollution, and has huge engineering quantity, environmental pollution caused by waste of water resource waves and great loss. Even if the slope protection is as good as before after the maintenance, the freezing injury can be repeated after the slope protection is pushed by the ice cover again.

Disclosure of Invention

Huge, the environmental pollution of the engineering volume that exists to prior art, the serious problem of wasting of resources, the utility model provides a prevent stone slope protection structure of frozen damage destruction, the protection slope body does not receive the ice lid extrusion to destroy.

In order to achieve the above object, the utility model provides a prevent stone slope protection structure of damage by freezing, including the soil bank protection, its characterized in that: the soil slope protection surface is provided with large stones in a building mode, large stone protection bodies are formed on the soil slope protection surface, the large stone protection bodies are 3-5m higher than the ice cover along the slope surface direction, the lower portions of the large stone protection bodies extend to the bottom slope feet, the slope feet of the large stone protection bodies are large stone foundations, the large stone protection bodies on the large stone foundations and at the positions of half of the thickness of the ice cover are large stone steps, the edges and corners of the large stone steps are in an outward thorn shape, and the stone slope protection bodies are arranged on the large stone steps.

Furthermore, small stones are selected in gaps among the large stones at each part of the large stone protection body to be embedded and laid, and the large stone protection body is tightly compacted, so that the large stone protection body forms a compact and firm whole, and the aims of uniformly dispersing the horizontal thrust of the ice cover and reducing the slope protection pressure are fulfilled.

Furthermore, the diameter of the large stone blocks is 0.6-0.8m, and the diameter of the small stone blocks is 0.2-0.5 m.

The utility model discloses positive effect: when the ice cover of the reservoir and the lake in the season freezing area extrudes the large stone protective body due to frost heaving, the reaction force generated by the high-strength hard large stone step on the ice cover shears the split ice cover, and the thrust is weakened or eliminated; meanwhile, edges and corners at each position of the large stone body protecting surface split the ice cover, so that the freezing thrust of the ice cover is further weakened. The ice cover thrust which is continuously increased in winter is eliminated under the continuous shearing and splitting of the large stone protective body until the ice cover is unfrozen in spring warm. The rock slope protection structure damaged by frost damage continues to play a role in the next winter.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1-slope protection; 2-a large stone foundation; 3-large stone steps; 4-stone slope protection body; 5-ice cover; 6-breaking the ice cubes.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Referring to fig. 1, the utility model relates to a prevent stone slope protection structure of freezing damage, including soil bank protection 1, soil bank protection 1 is domatic to be built the piece stone, forms the bold stone and protects the body at the bank protection face, and the space between each position bold stone of bold stone protects the body selects the piece stone to inlay and builds, and crowded reality is tight, and wherein bold stone block footpath 0.6-0.8m, and the piece stone footpath 0.2-0.5m makes the bold stone protect the body and forms closely knit, firm whole, reaches 5 horizontal thrust of homodisperse ice lid, alleviates bank protection pressure, and bold stone protects the body and exceeds ice lid 3-5m along 1 domatic direction in soil bank protection, and the lower part extends to 1 submarine toe in soil bank protection. And building a large stone step 3 on the slope protection surface at the position of half thickness of the ice cover 5, wherein the large stone step 3 is a sharp-edged body in the shape of a corner angle and is built according to the shape of the step. A big stone foundation 2 is built at the bottom slope toe of the soil slope protection 1 in a building mode, a big stone step 3 on the upper portion is supported, and a stone slope protection body 4 is arranged on the big stone step 3.

When the ice cover is temporarily used in winter, the thrust of the ice cover 5 which is continuously increased is eliminated and broken under the continuous shearing and splitting of the large stone protective body 3 to form a broken ice block 6, so that the slope body is protected from being extruded and damaged by the ice cover.

The utility model discloses the work progress:

1. selecting and transporting materials: selecting large stone blocks with the diameter of 0.6-0.8m and small stone blocks with the diameter of 0.2-0.5 m. Conveying the block stone to the side of the slope protection operation surface for later use;

2. trimming and tamping the slope protection soil to be used as a base layer of the large stone protection body;

3. the building of the large stone protection body is carried out in the construction sequence from bottom to top, a large stone foundation at the lower part of the large stone protection body is built firstly, then large stone steps are built, and finally the stone slope protection body is built. When the stones are piled, the stones need to be tried to be placed, the large surface faces downwards, and the large stones are inlaid by selecting the small and medium stones with the gaps of the same size. In the process of building, the firmness of the building body is checked at any time, and loosening is avoided. The rock blocks are loaded in the reinforcement cage and conveyed to the slope. The diving suit is worn in underwater operation, a safety rope is tied, and full-time safety protection personnel are arranged for protection.
