technical field

The utility model relates to the technical field of construction, in particular to a gravity-type point-glued rubble plant caulking ecological retaining wall.

Background technique

The traditional gravity-type rubble retaining wall can be divided into two types: cement mortar masonry and dry-build, or called "gravity cement mortar masonry rubble retaining wall" and "gravity dry-build rubble retaining wall". ". The surface of the rubble retaining wall built with gravity cement mortar is divided into two types: cement mortar pointing and joint free, or "gravity cement mortar masonry, pointing rubble retaining wall, gravity dry masonry rough Stone free pointing retaining wall".

Disadvantages of gravity cement mortar masonry and pointing rubble retaining wall: ①Using a large amount of cement; ②Cement mortar pointing is not beautiful, durable, and does not absorb sunlight and heat; ③The adjacent part of the retained drain retains soil The soil in the wall is also gradually lost. Once the drain is blocked, the excessive earth pressure will cause collapse, which poses a safety hazard; ④ the cost is relatively high.

The disadvantages of gravity dry-laying rubble retaining wall are: ① The overall stability is poor, and the gaps in the wall are large; ② Due to the irregular rubble, it is necessary to use smaller stone flakes for lining, which makes it difficult for workers to operate and low work efficiency; ③ The soil is easy to Loss through the gaps in the wall; ④ The surface is not beautiful, does not absorb sunlight and heat.

How to improve the above-mentioned defects of the wall, reduce cost, improve stability, improve appearance, and reduce loss are problems to be solved.

Among them, the total height of the ecological retaining wall is 1.5 meters to 5 meters.

Wherein, there is at least one pull stone in every 0.7m ² in the wall.

Wherein, the drainage ditch is made of groove-type cast-in-place concrete.

Among them, rough stone is a shapeless stone that is in a natural state after mining. It is an irregularly shaped stone obtained after rock blasting. The irregularly shaped one is called chaotic stone, and the one with two roughly parallel surfaces is called flat stone.

Among them, the point-bonded rubble is to choose some thinner flakes of rubble as the spot-bonded rubble. Point sticking is bonding with cement mortar.

The beneficial effects of the utility model are as follows: the utility model realizes less cement consumption; low engineering cost; plants grow rapidly and the surface is beautiful; durable, plants grow all year round; Air; the overall permeability coefficient is large, and a large amount of water can pass through the wall while the plant root system retains the soil; there is no need to leave weep holes; the plant root system can not only retain the soil, but also permeable; good stability; good soil retention.
