Problems solved by technology

[0002] The water and soil loss of the river bank slope is one of the problems that are difficult to control today. At this stage, the retaining wall is piled up with stones or the protective net is set on the slope to directly plant turf to ensure the water and soil loss. It has the following defects: 1) using The retaining wall is piled up with stones, and the outside of the stones is relatively rough, which is easy to cause safety accidents. At the same time, the outer surface of the stones is exposed and weathered, and the service life is low; In the rainy season, the rain can wash out the soil and turf, and the engineering limitations are high; 3) When the foundation conditions change, such as uneven settlement, earthquakes, etc., it is easy to cause rocks to fall or the protective net to be pushed down as a whole, causing the ramp is destroyed

Embodiment Construction

[0031] Such as Figure 1 to Figure 5 Shown, be a kind of gabion retaining wall construction method that is applied to bank slope protection of the present invention, comprises the steps:

[0032] (a) Excavation of the foundation pit: Excavate the foundation pit according to the construction level points on the design and construction drawings, and adopt the method of mechanical slotting and manual cleaning. During the excavation process, reserve 5-8cm at the bottom of the pit for manual work Clean up, avoid over-excavation, disturb the base, etc., which will affect the quality of the project, control the slope of the bottom of the foundation pit, make it slope 2 to 5% toward the bank, and effectively guide the water in the foundation pit to the river. Ditches are excavated on both sides, and the sides of the ditch are sloped according to 1:2~1:3, and a drainage ditch with a width of 10~20cm is left in the middle for foundation pit drainage.

[0033] (b) Reinforcement of the f...

Abstract

The invention discloses a gabion retaining wall construction method applied to bank slope protection. The method comprises the steps of (a) excavation of a foundation pit, (b) reinforcement of the foundation pit, (c) gabion rock filling, (d) backfilling, (e) afforesting and (f) monitoring and measurement. The method includes few construction procedures and is convenient to operate, low in cost, high in environmental affinity, high in overall construction efficiency and easy in quality and safety control, the construction progress can be accelerated through cooperation of manpower and machinery, the good economic benefit can be obtained, and the method is suitable for more projects, has the broad application prospect and is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and flood control facilities, and in particular relates to a construction method of a gabion retaining wall applied to bank slope protection. Background technique [0002] The water and soil loss of the river bank slope is one of the problems that are difficult to control today. At this stage, the retaining wall is piled up with stones or the protective net is set on the slope to directly plant turf to ensure the water and soil loss. It has the following defects: 1) using The retaining wall is piled up with stones, and the outside of the stones is relatively rough, which is easy to cause safety accidents. At the same time, the outer surface of the stones is exposed and weathered, and the service life is low; In the rainy season, the rain can wash out the soil and turf, and the engineering limitations are high; 3) When the foundation conditions change, such as uneven settlement, earthquak...
