Problems solved by technology

Due to the upright walls, the upper and lower planting tanks block each other, and only the top layer of planting tanks can receive rainfall, and the rest of the planting tanks can only be watered manually, which is time-consuming and laborious, resulting in a non-self-sustainable ecosystem
Therefore, there is a lack of a method for constructing retaining walls that can meet the strength requirements and can continuously provide the water and nutrients needed by plants to form a long-term ecological landscape.

Embodiment 1

[0034] see Figure 1-3 , a panel-reinforced ecological retaining wall structure with pre-buried culverts, which includes a retaining wall 1, a geogrid 2 is arranged on the back of the retaining wall 1, and the geogrid 2 is embedded in the reinforced soil 3, the upper part of the reinforced soil body 3 is provided with a pre-embedded culvert 5, the pre-embedded culvert 5 communicates with the drip irrigation pipeline 8 through the communication pipe 4, and the drip irrigation pipeline 8 passes through the interior of the retaining wall 1, The other end of the drip irrigation pipe 8 is connected with the planting groove 10 , and the planting groove 10 is fixed on the outer wall of the retaining wall 1 . By adopting the ecological retaining wall structure of the above-mentioned structure, on the basis of ensuring the strength of the retaining wall itself, following the principle of using small amounts of water and releasing and utilizing large amounts of water, automatic use of r...

Embodiment 2

[0045] A method for constructing a panel-reinforced ecological retaining wall structure with pre-buried culverts, comprising the following steps:

[0046] Step 1: cast-in-place retaining wall 1 according to the existing construction technology, pre-embed fixing bolts 14 and drip irrigation pipeline 8 at a specified height, and allow the drip irrigation pipeline to be connected to the internal connecting pipe 4 of the reinforced soil body 3 in the later stage;

[0047] Step 2: After the strength of the retaining wall 1 reaches the design value, reserve the position of the drainage ditch 6 on both sides, lay the bottom geogrid 2, and fix it with U-shaped nails every 1.5-2.0 m on the laid geogrid ground;

[0048] Step 3: Backfill the soil to the height of the connecting pipe 4, let it be sealed and connected with the drip irrigation pipe 8, and make its upper end connected to the pre-buried underground ditch 5, the connecting pipe 4 passes through the middle of the geogrid 2, and...

Abstract

The invention provides a panel reinforced ecological retaining wall structure of a pre-buried blind ditch and a construction method. The panel reinforced ecological retaining wall structure comprises a retaining wall, a geogrid is arranged on the back of the retaining wall, the geogrid is embedded inside a reinforced soil body, the upper portion of the reinforced soil body is provided with the pre-buried blind ditch, the pre-buried blind ditch is in communication with a drip irrigation pipeline through a communicating pipe, the drip irrigation pipeline penetrates through the retaining wall, the other end of the drip irrigation pipeline is connected with a planting groove, and the planting groove is fixed to the outer side wall of the retaining wall. On the basis of guaranteeing the strength of the retaining wall, the method can follow the criteria of small water use, large water discharge and utilization, automatic rainwater utilization and active drainage are achieved, and management is convenient; and a three-dimensional ecological landscape can be formed.

Description

technical field [0001] The invention relates to a panel-reinforced ecological retaining wall structure and a construction method of a pre-buried culvert, belonging to the field of slope protection engineering, and in particular to the construction of an ecological landscape of the retaining wall, which automatically utilizes rainwater and actively drains water, and is convenient for management. Background technique [0002] With the all-round development of national engineering construction, in highways, railways, tunnels, mines and other projects, due to the impact of construction excavation and backfilling, a large number of steep slopes are generated. When the bearing capacity of the foundation is poor and the filling slope support problem requires a large site space, the form of a reinforced retaining wall with a face plate is often used for support. [0003] The existing panel-reinforced retaining walls have few ecological measures, cannot adapt to the surrounding envir...
