An assembled lattice frame beam

Abstract

The invention discloses a high steep ecological protective slope with an assembled lattice frame beam, and belongs to the technical field of protective slope vegetation greening. In allusion to the problem that the current protective slope has a poor greening effect on a steep slope with high slope, the invention provides the assembled lattice frame beam. The assembled lattice frame beam is formedby assembling prefabricated cross beams, prefabricated vertical beams, prefabricated anchor rods and prefabricated ecological soil-retaining boards, wherein the cross beams, the vertical beams and the ecological soil-retaining board can form the lattice frame beam with the functions of retaining soil, preventing rainwater erosion and the like. The assembled lattice frame beam not only guaranteesthe stability of the slope, but also improves the durability of the ecological protective slope; meanwhile, the assembled lattice frame beam can avoid the problem of inconvenient construction of the high-steep slope during direct pouring of concrete and can also prevent vegetation damage caused by direct pouring of the concrete.

Description

technical field [0001] The invention belongs to the technical field of slope protection vegetation greening. Background technique [0002] With the rapid development of economic construction, the enhancement of environmental awareness, and the implementation of the scientific concept of development, it is required that the concept of environmental protection must be integrated into the construction of public infrastructure. Due to the formation of a large number of high and steep exposed slopes during the construction of the project, the living environment of vegetation has been destroyed, especially in the case of rain erosion, soil erosion is serious, and even geological disasters such as landslides and mud-rock flows will occur, endangering public safety and threatening people's lives and property. Higher environmental protection and stability requirements are put forward for the ecological protection of high and steep slopes. At present, slope protection projects includ...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, slope support structures such as retaining wall structure and soil nail wall structure cannot effectively realize slope ecological greening and meet environmental protection requirements

Although the traditional lattice project can be greened, it is limited to slopes slower than 1:1.5

[0005] 2. Soil and water are the necessary conditions for plant growth. For steeper rocky slopes, although the traditional flexible protective hanging net spraying planting was effective at that time, the soil was lost due to perennial rain erosion, strong wind and heavy snow. , resulting in severe damage to the substrate on which the plants depend, and the durability of the ecological greening effect on the slope is minimal

The current slope regreening technology of foreign soil spraying is easily affected by gravity and rain, and the sprayed base material is easily washed away, and the spraying thickness cannot meet the requirements, resulting in waste of spraying base material and soil erosion. The site condition of the slope is poor, and the vegetation is difficult to survive, which is not conducive to the overall regreening and landscape effect

[0006] 3. It is difficult to guarantee the stability of the slope by spraying the base material for greening and constructing the ecological protection slope method of the floating plate planting trough, and it is difficult to control the spraying thickness of the base material during construction. A large spraying thickness of the base material will affect the stability of the slope and increase Project cost, too thin is not conducive to vegetation growth, and the durability of ecological greening is low

[0007] 4. Due to the high and steep slope, the construction site is small, and it belongs to high-altitude operations. The vertical transportation of concrete is a difficult point in construction. In the case of high and steep slopes, the use of lattice beams in the existing slope protection is not suitable for construction, and the ability to resist rain erosion Limited, low vegetation survival rate, high maintenance cost
