Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, specifically to a soil stabilization structure for municipal pipeline laying construction. Background Technology

[0002] In urban construction, pipelines are required for infrastructure such as water supply and drainage, electricity, and gas. With the modernization of cities, the expansion of urban scale, and the upgrading of equipment, pipeline deployment needs to be increased. However, due to the high utilization rate of urban land, not all areas can be excavated and buried. Instead, end-push methods are used. However, in some areas, the soil is soft, and the soil can easily change drastically during the push-in process. For example, the pressure from above can cause the pipeline to deform or the above-ground structure to collapse. The impact is particularly large under roads. Therefore, it is necessary to grout around the pipeline. The grout mixes with the soil to form a high-strength structure, which protects the pipeline and provides high-strength support to prevent the above-ground structure from collapsing. However, the grouting equipment needs to be drilled before the pipeline is inserted into the soil. During the lowering process, mud, sand, or gravel inevitably enter the open pipe opening, which can easily cause blockage, resulting in high resistance to grout discharge and reduced flow. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed soil stabilization structure for municipal pipeline laying construction, which can solve the above-mentioned defects and deficiencies of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes an internally penetrating protective cylinder, a cone head slidably connected to the bottom end of the protective cylinder, the cone head being positioned downwards, and a protective cover connected to the top of the protective cylinder via a movable snap-fit ​​mechanism.

[0005] Preferably, the top of the cone is connected to a plurality of sliding plates, and the inner side of the top of each sliding plate is connected to a sliding protrusion. The bottom of the outer side of the protective cylinder is provided with a plurality of inverted "L"-shaped grooves. The sliding plates and sliding protrusions are slidably disposed in the grooves, and the sliding protrusions slide in the inwardly concave part of the grooves.

[0006] Preferably, the top of the protective cylinder is connected to a connecting ring, and multiple sets of connecting grooves are opened at the edge of the connecting ring. A circular groove matching the shape of the connecting ring is opened inward on the bottom side of the protective cover.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figures 1-5As shown, it includes an internally penetrating protective cylinder 1. A cone head 2 is slidably connected to the bottom end of the protective cylinder 1, with the cone head 2 facing downward. A protective cover 3 is connected to the top of the protective cylinder 1 through a movable buckle mechanism. This is used to facilitate local pressure buffering when the protective cylinder 1 is driven into the ground, preventing deformation of the top surface of the protective cylinder 1. Each protective cover 3 is equipped with a top protective pad 7, which is made of rubber with a certain degree of flexibility to prevent uneven local pressure.

[0023] The top of the cone head 2 is connected to multiple sliding plates 8. The sliding plates 8 are evenly arranged on the cone head 2 along the circumferential direction. The inner side of the top of each sliding plate 8 is connected to a sliding protrusion 9. The bottom of the outer side of the protective cylinder 1 is provided with multiple inverted "L"-shaped sliding grooves 10. The sliding plates 8 and the sliding protrusions 9 are slidably disposed in the sliding grooves 10. The sliding protrusions 9 slide in the inwardly concave part of the sliding grooves 10.

[0024] The top of the protective cylinder 1 is connected to a connecting ring 4. Multiple sets of connecting grooves 5 are opened at the edge of the connecting ring 4. A circular groove matching the shape of the connecting ring 4 is opened inward on the bottom side of the protective cover 3. Multiple connecting blocks 6 are evenly arranged along the circumference of the groove. The protective cover 3 is installed with the connecting ring 4 through the connecting blocks 6 and the connecting grooves 5. When the protective cylinder 1 is driven into the ground and needs to be used, the protective cover 3 can be rotated to remove it so that the grouting pipe can pass through.

[0025] A groove is opened at the center of the upper side of the cone head 2, and multiple inclined liquid outlet grooves 11 are opened on the outer side of the groove. One end of the liquid outlet groove 11 is connected to the bottom surface of the groove, and the other side is connected to the edge of the cone head 2. Therefore, when the grouting pipe is inserted to the bottom, even if the opening of the grouting pipe is in contact with the top surface of the cone head 2, the grout will enter the groove and then flow out quickly through the liquid outlet groove 11.

[0026] In use, place the entire structure downwards at the location requiring grouting, and use a pressure device to drive it into the ground until the desired depth is reached. Then, rotate the protective cover 3 to remove it. Simultaneously, use a lifting device to pull the protective cylinder 1 upwards a certain distance via the connecting ring 4. During the downward driving process, the cone head 2 is compressed and kept in contact with the protective cylinder 1. During the pullback, under the action of friction, the sliding protrusion 9 slides within the groove 10, separating the cone head 2 from the protective cylinder 1. Figure 4 In the state shown, instead of pulling back, a cylindrical high-hardness rod can be inserted into the protective cylinder 1, pressed against the cone 2, and pressure applied to drive the cone 2 downward a certain distance so that the cone 2 separates from the protective cylinder 1; then the grouting pipe can be inserted into the protective cylinder 1 until it reaches the bottom and grouting can begin.

[0027] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.

[0028] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
