Description

Technical Field

[0001] This invention relates to the field of slope protection technology, and in particular to a slope protection device based on the synergistic maintenance of microbial grouting and vegetation. Background Technology

[0002] In various civil engineering construction projects, slope stability is one of the key factors to ensure the long-term safe operation of the project. The construction of infrastructure such as roads and railways often involves a large number of slope engineering projects. Once a slope becomes unstable, it may trigger geological disasters such as landslides and collapses, which will not only cause serious damage to the engineering structure, but may also threaten the lives and property of people in the surrounding area.

[0003] Traditional slope reinforcement methods, such as using anchor bolts and anchor cables, can improve slope stability to some extent, but these methods involve complex construction processes, require specialized construction equipment and technicians, and increase construction difficulty and cost.

[0004] Slope vegetation not only beautifies the environment but also enhances slope stability through root stabilization and rainwater interception. Therefore, timely maintenance of vegetation is necessary during slope management, as exemplified by the rock slope protection structure described in patent number CN223410187U. Currently, slope vegetation maintenance mainly relies on manual irrigation or independent irrigation systems, which are independent of microbial grouting operations. This results in low construction efficiency, high equipment investment costs, and difficulty in achieving coordinated grouting and maintenance. Summary of the Invention

[0005] The purpose of this invention is to provide a slope protection device based on the synergistic maintenance of microbial grouting and vegetation, which solves the problem that existing slope protection methods rely on vegetation beautification, which requires artificial irrigation or independent irrigation systems, and the protection effect of a single protection method is generally not good.

[0006] This invention is implemented as follows: It provides a slope protection device based on the synergistic maintenance of microbial grouting and vegetation, comprising a drilling and grouting module, a drilling-grouting connection module, an intelligent liquid supply module, and an air booster pump. The drilling and grouting module includes a grouting drill bit and an electric drill. The grouting drill bit is hollow inside and has multiple grouting ports and inlets communicating with the hollow part. The grouting drill bit is connected to the electric drill. The drilling-grouting connection module includes a hose and a connector. The connector is sleeved on the grouting drill bit, and the hose is connected to the connector to connect the grouting drill bits. The intelligent liquid supply module is connected to the connector via the hose. The intelligent liquid supply module includes a storage tank, a grout outlet valve and a sealing cap on the storage tank, and a pressure valve on the sealing cap. The air booster pump is connected to the pressure valve of the intelligent liquid supply module via a pipeline.

[0007] The core modules of the equipment were defined, and the modular design enabled integrated and coordinated operation of drilling, grouting and vegetation irrigation. This solved the problem of low efficiency caused by the independent operation of grouting and maintenance in traditional processes, and improved the overall efficiency of slope treatment and ecological restoration.

[0008] A further technical solution of the present invention is as follows: the connector includes an inner cylinder and a hollow outer cylinder sleeved on the outer periphery of the inner cylinder; a first connecting pipe is provided on the inner cylinder, the first connecting pipe extends from the inner wall of the inner cylinder to the outer cylinder, and is used to connect the hose to the grout inlet of the grouting drill bit; a second connecting pipe is provided on the outer wall of the outer cylinder, the second connecting pipe is connected to the hollow cavity of the outer cylinder, and is used to connect the hollow cavities of two adjacent connectors.

[0009] The connector’s unique double-cylinder structure enables a quick and sealed connection between the grouting drill bit and the hose, as well as between the hoses. In particular, the hollow cavity of the outer cylinder provides an independent channel for the delivery of the curing fluid, allowing microbial grouting and vegetation irrigation to proceed in parallel without conflict. This is a key structure for achieving collaborative operation.

[0010] A further technical solution of the present invention is: the connector is sleeved on the outer periphery of the grouting drill bit through its inner cylinder, and an elastic sealing layer is provided between the inner cylinder and the grout inlet of the grouting drill bit.

[0011] The elastic sealing layer effectively prevents leakage of grout and curing fluid at the connection between the grout inlet and the connector, ensuring grouting pressure, avoiding material waste, maintaining the cleanliness of the construction area, and improving the reliability and durability of the equipment.

[0012] A further technical solution of the present invention is: the hose is a double concentric sleeve structure, including a connecting hose as an inner tube and an injection hose as an outer tube sleeved thereon; the connecting hose is used to transport microbial consolidation liquid and is connected to the hollow part of the grouting drill bit; the injection hose is used to transport vegetation maintenance liquid, and its pipe wall is provided with multiple injection ports.

[0013] The flexible hose, employing a double concentric sleeve structure, enables the simultaneous delivery of two different media through a single pipe, greatly simplifying the pipeline layout and making the equipment structure more compact. The inner pipe is dedicated to injecting microbial inoculants, while the outer pipe is dedicated to vegetation irrigation, physically ensuring the independence and synergy of the two functions.

[0014] A further technical solution of the present invention is that a pressure gauge for detecting the pressure inside the tank is also installed on the sealing cover of the intelligent liquid supply module.

[0015] The pressure gauge provides operators with intuitive tank pressure data, facilitating real-time monitoring and precise control of grouting pressure. This ensures that the grout can penetrate the slope soil evenly and effectively, preventing insufficient pressure from causing incomplete grouting or excessive pressure from damaging the equipment, thus improving construction quality and safety.

[0016] A further technical solution of the present invention is: the lower inner chamber of the storage tank is configured as a bacterial liquid chamber, the lower outer chamber is configured as a curing liquid chamber, and a cementing liquid chamber is provided in the upper middle part, and a cementing liquid chamber switch for controlling the mixing of cementing liquid and bacterial liquid is provided at the bottom of the cementing liquid chamber.

[0017] This compartmentalized design allows for the separate storage of bacterial solution, cementing solution, and vegetation maintenance solution. By controlling the opening and closing of the cementing solution compartment, the mixing timing of the bacterial solution and cementing solution can be precisely controlled, preventing them from reacting prematurely and becoming ineffective in the storage tank. This ensures that the microbial-induced calcium carbonate precipitation reaction mainly occurs within the slope soil, thereby significantly improving the grouting reinforcement effect.

[0018] A further technical solution of the present invention is: the sealing cover is equipped with an electric mixer, which is used to mix the cementitious liquid and the bacterial liquid evenly.

[0019] Electric mixers can quickly and thoroughly mix bacterial solution and cementing solution before grouting, preventing grout sedimentation or stratification and ensuring the consistency of grout composition and reactivity in each grouting.

[0020] A further technical solution of the present invention is that a slurry outlet valve is installed at the slurry outlet on one side of the bottom of the storage tank.

[0021] The grout outlet valve allows operators to flexibly control the delivery of grout, such as selectively grouting different areas of the slope or different grouting drill bits, improving the flexibility and precision of construction.

[0022] A further technical solution of the present invention is that the bottom of the liquid storage tank is provided with casters.

[0023] The casters give the entire fluid supply system excellent mobility, enabling the equipment to be easily moved and positioned on complex construction sites, adapting to different slope conditions, and greatly improving the flexibility and overall efficiency of construction.

[0024] A further technical solution of the present invention is that the grout inlet is located near the top of the grouting drill bit.

[0025] By placing the grout inlet near the top of the drill bit, the grout is injected from the top of the drill bit's hollow cavity, flows downwards, and exits through multiple grouting ports distributed along the drill bit's wall. This design facilitates the grout filling of the entire internal cavity of the drill bit and ensures that the grout is evenly injected into the soil from grouting ports at different depths, avoiding grouting dead zones and uneven grout distribution.

[0026] The beneficial effects of this invention: This invention is a slope protection device that organically combines microbial grouting with vegetation maintenance, enabling the two to work synergistically. This is of great significance for improving slope treatment efficiency, reducing construction costs, and enhancing ecological restoration effects.

[0027] The technical problem to be solved by the present invention is to provide a slope protection device based on the synergistic maintenance of microbial grouting and vegetation. This device can realize the synergistic operation of microbial grouting reinforcement and slope vegetation maintenance, thereby improving the efficiency of slope treatment and the effect of ecological restoration.
