Problems solved by technology

[0004] However, there are some problems in the existing grid gabion slope protection (bank) technology: 1) The filling material used is stone, which sometimes needs to be excavated and transported from other places, and the cost is relatively high; 2) The existing technology does not solve the problem of rapid greening
Because the gabion wall generally has a relatively large slope, the slope protection of the gabion wall built in the prior art, the greening of the wall either depends on the grass species naturally flying into the gabion pores to germinate and grow (such as figure 1 ); or by planting or cutting plants in the gabion holes; these practices are inefficient and take a long time for vegetation to cover the entire wall

preparation example Construction

[0038] Unless otherwise specified, the improved vegetation concrete greening additive used in the embodiments of the present invention is the product provided by Patent No. ZL201110380711, and its preparation method comprises the following steps:

[0039] (a) prepare sulfur-rich bacterial powder A:

[0040] The sulfur bacteria are put into the sucrose solution for cultivation, and the powder A rich in sulfur bacteria is obtained after dehydration treatment, the addition amount of the sulfur bacteria and the sucrose solution is 1 part by weight of the sulfur bacteria, 800 to 1200 parts of the sucrose solution, The concentration of the sucrose solution is 2%; when the sulfur bacteria are cultured in the sucrose solution, the pH value of the control solution is 2~3, and the culture time is 24 hours;

[0041] (b) Preparation of mixture B:

[0042] In parts by weight, 10-18 parts of iron ore powder, 20-30 parts of calcium powder, 30-40 parts of phosphate rock powder, 10-20 parts o...

Embodiment 1

[0046] (1) The construction waste composed of broken bricks or broken concrete is crushed and screened, lime and other sundries are removed, and densely filled in the gabion box made of galvanized iron wire with a PVC protective layer. The particle size of the construction waste is larger than Gabion mesh size, but less than twice the mesh size; and on the slope or river bank that needs to be protected according to figure 1 Installed in the form shown to form a gravity gabion retaining wall.

[0047] (2) Prepare a mixture consisting of cement, clay, river sand, organic matter and improved vegetation concrete greening additives according to the following ratio, and the content of each component of the mixture per cubic meter (volume percentage):

[0048] Cement: 10%;

[0049] Clay: 70%;

[0050] River sand: 10%

[0051] Organic matter: 8%;

[0052] Improved vegetation concrete greening additive: 2%;

[0053] The above components are:

[0054] The cement is 325# ordinary Por...

Embodiment 2

[0078] (1) The construction waste composed of broken bricks or broken concrete is crushed and screened, lime and other sundries are removed, and densely filled in the gabion box made of iron wire. The particle size of the construction waste is larger than the mesh size of the gabion. But less than twice the mesh size; and on the slope or river bank that needs to be protected according to figure 2 Installed in the form shown to form a slope-style gabion protection.

[0079] (2) Prepare a mixture consisting of cement, clay, river sand, organic matter and improved vegetation concrete greening additives according to the following ratio, and the content of each component of the mixture per cubic meter (volume percentage):

[0080] Cement: 4%;

[0081] Clay: 70%;

[0082] River sand: 15%

[0083] Organic matter: 10%;

[0084] Improved vegetation concrete greening additive: 1%.

[0085] Wherein, the above-mentioned components are respectively:

[0086] The cement is 325# ordin...

Abstract

The invention discloses a slope protection method, wherein a gabion filled with construction wastes servers as a slope protection wall body, and quick afforestation is conducted to the gabion. According to the method, the gabion made of metal wires is filled with the construction wastes and is used for the ecological protection of a slope or a riverbank to form the slope protection wall body, and cement, clay, river sands, organic matters, improved vegetation concrete afforestation additives and plant seeds are injected into the slope protection wall body to afforest the slope protection wall body. The local recycling utilization of the construction wastes is achieved, degree of mechanization of the slope wall body quick afforestation method is high, cost is low, the contradiction between soil conservation and growth of plants is better solved, and application prospect is wide.

Description

technical field [0001] The invention relates to a slope protection method, in particular to a slope protection method in which construction waste is filled with gabions as a slope protection wall and quickly greened. Background technique [0002] The demolition of urban waste buildings will produce a large amount of construction waste mainly broken bricks and broken concrete. Except for a small part of these construction wastes, which are recycled to produce recycled aggregates and road base and foundation treatment materials, most of them are piled up in the open air, occupying a large amount of land. farmland and construction land. These rubbish, together with a large amount of household rubbish and other industrial rubbish, make many cities fall into the predicament of rubbish siege. How to utilize construction waste on site is an urgent problem to be solved. Considering that the raw material of red brick is clay; the raw material of concrete is clay and limestone, etc....
