Cast-in-place planting concrete construction method of saline-alkali soil

Abstract

The invention provides a cast-in-place planting concrete construction method of saline-alkali soil. The cast-in-place planting concrete construction method comprises the following steps of weighing components, mixing, forming, splashing nutrient soil, laying planting soil, planting turfs or splashing grass seeds. According to the cast-in-place planting concrete construction method, in the condition that the saline-alkali soil is not improved, greening slope protections are constructed in the saline-alkali soil in a cast-in-place mode, so that the saline-alkali soil is protected by the slope protections and has a good landscape effect and an excellent ecological service function, and the lack of landscapes due to single vegetation type because required soil nutrients are difficult to supply to plants due to high saline and alkaline of the saline-alkali soil can be changed to a certain degree; the cast-in-place planting concrete construction method has the advantages that manpower and material resources are saved, the construction cost is reduced, the overall stability of the greening slope protections is good, the anti-flood capacity is high, and the environment is beautified; and the cast-in-place planting concrete construction method is suitable for being used in the fields of greening of urban recreational green space, residence communities, parking lots, roof gardens and building walls, slope protections of highways, reinforcing dams of rivers and the like.

Description

technical field

[0001] The invention relates to the technical field of environmental protection, in particular to a construction method of cast-in-place greening concrete in saline-alkali land. Background technique

[0002] With the rapid development of my country's economy, the acceleration of urbanization and the increase of urban buildings have seriously affected the environment on which we live, and the pressure of environmental protection is increasing. Environmental problems have become a major problem hindering social progress and human development, and have received common attention from people.

[0003] With the increasing calls for environmental protection, maintaining ecological diversity, and maintaining sustainable social development, and the gradual implementation of relevant policies, all sectors of society have actively invested in ecological restoration and environmental protection, proposed many effective methods, and developed many Green building material...

Embodiment 1

[0046] The invention provides a construction method for cast-in-situ greening concrete in saline-alkali land, comprising the following steps:

[0047] 1) Weigh the following components and their mass parts: 500 parts of gravel with a particle size of 15-20 mm, 100 parts of P42.5 Portland cement, 60 parts of water, and 4 parts of special additives for greening concrete;

[0048] 2) After mixing the above-mentioned components, stir for 5 minutes to ensure that each gravel is wrapped by cement and ensure that the compressive strength is 5N / mm to obtain green concrete;

[0049] 3) After leveling the work surface to be built, lay the green concrete in step 2) on the work surface, scrape it flat, and shape it with a molding machine to form holes with a diameter of 25mm and a depth of 60-80mm on the surface, 130 per square meter ;
