Sandy slope microorganism curing liquid and sandy slope treatment method

Abstract

The invention provides a sandy slope microorganism curing liquid and a sandy slope treatment method, and belongs to the technical field of ecological management. The sandy slope microorganism curing liquid comprises a bacillus pasteurii bacterial liquid, a staphylococcus bacterial liquid, a lactobacillus plantarum bacterial liquid, urea, calcium ions, glucose and water. The sandy slope microorganism curing liquid can be directly sprayed on a sandy slope with a slow gradient, then soil covering and grass planting are conducted, and the effect of reinforcing the slope is achieved; the microorganism curing liquid can be used in combination with a side slope grouting process, and the reinforcing effect on the sandy slope with the steep slope is good; according to the sandy slope treatment method, the stability and durability of the slope can be effectively improved, the situation that the slope is eroded and damaged is prevented, the sandy slope treatment method is easy to operate, short in construction period and low in manufacturing cost, and conforms to the ecological environmental protection concept.

Description

Technical field [0001] The present invention belongs to the technical field ecological management, particularly to a sandy sandy slope and slope microorganism curable liquid treatment methods. Background technique [0002] Sandy cohesive force having a small slope, poor stability, the characteristics susceptible to rain erosion phenomenon landslide. [0003] At present, the commonly used method of treatment sandy slope main brush side-loading, the drainage unwatering, toe backpressure, like reinforcing the slope. Rock mass strength enhancement and reinforcement methods are prestressed anchor (cable) reinforcement, retaining walls and pile, pressure grouting, shotcrete, grout seepage, plant protection. However, the presence of conventional processing techniques sandy slope following problems: (1) Reinforcement sandy slope, since very soft sand, construction difficulties, resulting in pile, into the anchor hole in the reinforcing construction of large difficulty, easy to deviation,...

AI Technical Summary

Problems solved by technology

However, the existing sandy slope treatment technology has the following problems: (1) in the sandy slope reinforcement treatment, due to the extremely loose sand layer, the construction is difficult, resulting in the difficulty of forming holes in the reinforcement construction of anti-slide piles and anchor cables. Deviations, easy to collapse blocks, and collapsed holes seriously affect the treatment effect; (2) sandy slopes are prone to shallow local landslides, and also prone to deep overall landslides. Shallow local landslides mainly rely on shotcrete and grouting anti-seepage methods However, the concrete grout is easy to block the grouting seepage channel during construction, so that the local strength is difficult to meet the design requirements; the deep integral landslide relies on the reinforcement of anchor rods (locks), and the bonding force between the anchor rod cables and the sandy slope body It is provided by the friction between the cement slurry and the hole wall, and it is difficult for the sandy hole wall to provide enough friction to meet the reinforcement requirements of the high cutting sandy slope; (3) cement, lime and other cementitious materials used in slope reinforcement construction will It causes damage to the surrounding ecological environment, and it is difficult and expensive to restore the ecological environment after the reinforcement is completed; (4) For the cold and arid areas in the north, there is dryness and little rain, strong wind and sand, sparse vegetation, strong surface erosion and cutting, and low survival rate of grass planting. The growth condition is extremely poor, and the protection effect cannot be achieved
