Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a slope slag prevention structure used for road construction. Background Art

[0002] Currently, during the early stages of construction for transportation, water conservancy, and hydropower projects in mountainous and canyon areas, slope excavation causes a serious problem of slag hanging on the slopes. This slag sliding down the slope damages and exposes vegetation, creating a sharp contrast with the surrounding lush greenery and mountains, and is incompatible with ecological and environmental protection requirements. Therefore, it is necessary to implement slope protection measures during construction. Existing projects mostly use steel plate enclosures to prevent slag from sliding. Although steel plates have high structural strength and are effective in preventing slag hanging, they are expensive, the handling and installation process is cumbersome, and the labor intensity is high, making them unsuitable for widespread use in barren mountainous areas. Utility Model Content

[0003] In order to overcome the above-mentioned deficiencies of the existing steel plate enclosure anti-slag structure, the technical problem to be solved by the present invention is to provide a slope anti-slag structure for road construction with a simple structure and low cost.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A slope slag prevention structure for road construction includes a first baffle arranged on the slope surface, the first baffle is located on the side of the road construction surface close to the slope foot, faces the slope top, and is arranged along the extension direction of the road construction surface, the first baffle includes bamboo plywood and multiple columns arranged at intervals along the length direction of the bamboo plywood, the first baffle is inserted into the slope surface through the columns, and a diagonal brace is provided between the side of the column facing away from the road construction surface and the slope surface, and sandbags are piled on the side of the first baffle close to the road construction surface.

[0006] Furthermore, the columns are steel pipes or angle steels, the length of the columns inserted into the slope is not less than 1m, the height above the slope is not more than 1.5m, the spacing between adjacent columns is not more than 1.5m, and the height of the bamboo plywood is equivalent to the height of the columns above the slope.

[0007] Furthermore, the height of the sandbags is not less than 1 m, but not more than the height of the pillars.

[0008] Furthermore, the diagonal brace is a wooden column or a bamboo pole, the upper end of which is tied together with the upper end of the vertical column, and the lower end is inserted into the slope.

[0009] Furthermore, it also includes a second baffle, which has the same structure as the first baffle. The second baffle is arranged on the side of the first baffle away from the road construction surface, and the distance from the first baffle is 1.5-2m.

[0010] Furthermore, the first baffle and the second baffle are both arranged along the extension direction of the road construction surface in the form of a structure in which multiple baffle units are spliced ​​together, and the length of a single baffle unit is 2-3m.

[0011] The beneficial effects of the present invention are as follows: a slag retaining structure is formed by arranging a first baffle made of bamboo plywood on the side of the road construction surface close to the slope foot, and arranging sandbags on the side of the first baffle close to the road construction surface. On the one hand, it can buffer and stably block slag hanging on the slope surface; on the other hand, most of the structure is made of bamboo material, which can be locally sourced and has low cost. It takes into account the requirements of the ecological environment, engineering functions, safety, etc., and can effectively solve the problem of slag hanging on the slope surface of road traffic engineering.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] It should be noted that if directional terms are used in this utility model, such as "up," "down," "left," "right," "front," and "back," these are intended to facilitate the description of the relative positions of components and are not intended to specify the absolute positions of the related components or the positional relationships between them. They are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. If terms related to quantity are used in this utility model, such as "multiple," "a plurality," or "several," these specifically refer to two or more.

[0017] like Figure 1 、 Figure 2As shown, the utility model provides a slope slag prevention structure for road construction, including a first baffle 1 arranged on the slope 3, the first baffle 1 is located on the side of the road construction surface 4 close to the slope foot, facing the slope top, and arranged along the extension direction of the road construction surface 4, the first baffle 1 includes a bamboo plywood 11 and a plurality of columns 12 arranged at intervals along the length direction of the bamboo plywood 11, the first baffle 1 is inserted into the slope 3 through the columns 12, and a diagonal brace 13 is provided between the side of the column 12 facing away from the road construction surface 4 and the slope 3, and a sandbag 5 is piled on the side of the first baffle 1 close to the road construction surface 4. The bamboo plywood 11 refers to a bamboo board structure woven from bamboo strips. The bamboo plywood 11 is used as the main body of the first baffle 1, which has a certain structural strength and toughness, can play a stable slag blocking role, and can be made of local materials, with low production cost and relatively light material, which is convenient for transportation and installation. The diagonal brace 13 is used to increase the supporting force of the first baffle 1. Sandbags 5 are piled on one side of the first baffle 1 close to the road construction surface 4 to cushion the falling stones, thereby preventing the stones from impacting and damaging the bamboo plywood 11 and prolonging the service life of the first baffle 1.

[0018] To ensure the stability of the first baffle 1 when installed on the slope, the posts 12 are preferably made of a high-strength material such as steel pipe or angle steel, which also allows for easier insertion into the slope 3. Furthermore, if there are trees along the slope's path along which the first baffle 1 is installed, they can serve as posts or diagonal braces. Specifically, during installation, to ensure support strength, the posts 12 should be inserted into the slope 3 to a depth of no less than 1 meter, and their height above the slope 3 should not exceed 1.5 meters. The spacing between adjacent posts 12 should not exceed 1.5 meters. The height of the bamboo plywood 11 should correspond to the height of the posts 12 above the slope 3.

[0019] According to the amount of slag caused by slope excavation in general projects, in order to stably cushion the falling stones, the height of the sandbag 5 should be no less than 1m, but no higher than the height of the column 12, to avoid the sandbag tilting and increasing the burden on the first baffle 1.

[0020] For the diagonal brace 13 , in order to save costs, local materials can also be used, such as wooden posts or bamboo poles, the upper ends of which are tied together with the upper ends of the upright posts 12 , and the lower ends are inserted into the slope 3 .

[0021] Furthermore, for construction areas with larger excavated slopes, a second barrier 2 can be installed. This barrier 2 has the same structure as the first barrier 1, also employing bamboo plywood 11, columns 12, and diagonal braces 13. The second barrier 2 is positioned on the side of the first barrier 1 facing away from the road construction surface 4, with a distance of 1.5-2 meters from the first barrier 1. This allows for double protection when debris accumulates and overruns or damages the first barrier 1, providing additional protection.

[0022] During road construction, it is common to move a slag retaining structure after constructing a certain distance. Therefore, to facilitate transfer and installation, the first and second retaining plates 1 and 2 can be configured as a structure formed by splicing multiple retaining plate units. Each retaining plate unit is 2-3 meters long and is connected and installed along the extension direction of the road construction surface 4 during paving. Keeping the length of a single retaining plate unit within 2-3 meters facilitates carrying by two people and prevents deformation or damage to the bamboo plywood 11.
