Description

Technical Field

[0001] This utility model relates to the field of soil and rock reinforcement technology, and in particular to grouting pipes for slope reinforcement. Background Technology

[0002] With the rapid development of infrastructure construction, the construction of highways and railways in mountainous areas has led to a surge in slope engineering projects. During the construction of these transportation lines, it is inevitable to carry out mountain cutting and filling operations, resulting in numerous artificial slopes. In the construction of highways in the mountainous areas of Southwest China, in order to meet the required slope and elevation, large-scale excavation of mountains is often necessary, forming slopes tens or even hundreds of meters high. If these slopes are not effectively reinforced, they are prone to collapse and other safety hazards during subsequent use, affecting the normal operation of transportation lines. Urban construction projects and underground space development projects also involve slope issues. When excavating a foundation pit, the surrounding soil forms a slope, which needs to be reinforced to ensure the stability of the pit and construction safety. This is especially true in soft soil areas where deep foundation pit excavation is carried out, where the stability of the slope soil is even worse, requiring higher reinforcement technology. Natural slopes are inherently at risk of instability under long-term natural environmental influences. In areas with abundant rainfall, rainwater infiltration is one of the important factors leading to slope instability. In the southeastern coastal areas of my country, the annual rainfall during the rainy season is relatively large. After rainwater seeps into the slope soil, it increases the density of the soil and reduces its shear strength. When the shear force inside the soil exceeds its shear strength, it can easily trigger geological disasters such as landslides and debris flows.

[0003] Anti-slide piles are a common method of slope reinforcement. They mainly work by embedding piles deep into stable strata, using the shear and bending resistance of the piles to prevent slope sliding. However, anti-slide pile construction involves a large amount of work and is costly. In some complex geological conditions, such as areas with many boulders or high groundwater levels, the construction difficulty is further increased. Retaining walls can rely on their own weight or other structural forms to prevent slope sliding. However, retaining walls need sufficient foundation bearing capacity. For high slopes or soft foundations, retaining walls may crack and overturn due to excessive earth pressure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a grouting pipe for slope reinforcement, which aims to improve the problems of large engineering volume, high cost and breakthrough cracking in the existing technology.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a grouting pipe for slope reinforcement, comprising a transport pipe, a gate valve connected to the left side of the transport pipe, a turntable rotatably connected to the top of the gate valve, a threaded hole in the middle of the gate valve, a grout output pipe at the bottom of the transport pipe, multiple circular holes in the lower middle part of the grout output pipe, a drill bit fixedly connected to the bottom of the grout output pipe, a threaded connection port threaded to the inner wall of the threaded hole, a grout tank fixedly connected to the left side of the threaded connection port, multiple legs fixedly connected to the bottom of the grout tank, telescopic columns slidably connected to the bottom of the legs, a grout inlet fixedly connected to the top left side of the grout tank, and a connecting mechanism fixedly connected to the bottom edge of the transport pipe, the connecting mechanism being used for quick connection of the pipe, providing convenience.

[0006] As a further description of the above technical solution:

[0007] The connecting mechanism includes a first connecting ring, the top of which is fixedly connected to the bottom edge of the transport pipe, and a protruding ring fixedly connected to the bottom of the first connecting ring. A second connecting ring is engaged with the bottom of the protruding ring. An annular groove is formed on the top of the second connecting ring, and threaded grooves are formed near the edge of the top of the second connecting ring. A screw is threadedly connected to the inner wall of the threaded groove, and an open nut is threadedly connected to the bottom of the screw. An open nut is slidably connected to the bottom of the open nut.

[0008] As a further description of the above technical solution:

[0009] The top of the pulp tank is provided with a top cover, and a reflective ring is fixedly connected to the upper middle part of the outer wall of the pulp tank.

[0010] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when grouting a slope, the grout is injected into the grout bucket and transported to the transport pipeline through its multiple threaded connection ports. The turntable is rotated to open the gate valve, and the grout flows into the soil through the circular hole on the grout output pipeline. By connecting multiple transport pipelines, grouting can be carried out at multiple locations at the same time, which effectively reduces the amount of work and cost and improves the reinforcement efficiency.

[0022] 2. In this utility model, when adding a pipe in a deep pit, the first connecting ring and the second connecting ring are clamped and aligned to ensure that the protruding ring falls into the annular groove. After rotating to the appropriate position, the screw is inserted into the threaded groove, and the first open nut and the second open nut are installed at the bottom. When it can no longer be rotated, the second open nut is adjusted at a certain angle so that the openings of the two open nuts are staggered, forming a structure for quick connection of the pipe. This allows users to extend the pipe as needed to adapt to pits of different depths. Attached Figure Description

By rotating the turntable 4, the gate valve 3 is opened, allowing the grout to be delivered from the grout tank 10 to the transport pipe 1, and then along the path to the grout output pipe 6. The outer wall of the grout output pipe 6 has a circular hole 8, allowing the grout to flow out and into the soft soil. The multiple threaded connection ports 9 at the bottom of the grout tank 10 can be connected to multiple transport pipes 1, allowing grouting to be performed on multiple sites simultaneously. This reduces the amount of work and achieves the reinforcement effect at a low cost. This structure for simultaneous grouting of multiple sites provides convenience for users and makes the process more efficient.

[0040] When the pit is deep and additional pipes are needed, align and tighten connecting ring 1 201 and connecting ring 2 204, so that the protruding ring 202 accurately falls into the annular groove 203. Rotate to the appropriate position, align the screw 206 with the threaded groove 205 and insert it. Rotate the open nut 1 207 and open nut 2 208 at the bottom of the screw 206. When it can no longer be rotated, rotate the open nut 2 208 at the bottom by a certain angle so that the openings of the open nut 1 207 and open nut 2 208 are not facing the same direction. This structure allows for quick connection of the upper and lower pipes, and also makes it convenient for users to increase the length of the pipes to adapt to pits of various depths, making it convenient for users to use.
