Description

Technical field

[0001] The utility model relates to the technical field of slope waterproofing, in particular to a seepage-proof structure for geotechnical engineering. Background art

[0002] In the field of geotechnical engineering, slope protection is an important link to ensure the stability and safety of engineering; although the traditional slope seepage-proof structure can play a certain waterproof role, it has limitations in support strength and drainage effect; especially in the rainy season, due to untimely drainage, water will penetrate into the interior of the slope soil, thereby seriously affecting the overall stability of the slope structure; most of the existing seepage-proof structures rely on the water guide trough structure matched with the slope structure, which reduces the water permeability to a certain extent, but fails to effectively solve the problems of insufficient support strength and low drainage efficiency, resulting in safety hazards such as landslides or collapses prone to occur when the engineering encounters heavy rainfall. Therefore, we propose a seepage-proof structure for geotechnical engineering. Utility model content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to improve the support strength and drainage capacity of the slope structure under the challenges of complex geological conditions and extreme weather conditions.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A seepage-proof structure for geotechnical engineering comprises a main slope support structure, wherein the end of the main slope support structure away from the inclined surface of the slope on the road surface side is provided with an auxiliary slope support structure, a plurality of reinforcing bar connection structures are obliquely arranged between the top end of the main slope support structure and the auxiliary slope support structure, the periphery of the reinforcing bar connection structure is poured with a support frame, the top ends of the main slope support structure, the auxiliary slope support structure and the support frame are all provided with water guide troughs, and the main slope support structure, the support frame and the auxiliary slope support structure are sequentially communicated.

[0006] Further, the main slope support structure and the auxiliary slope support structure are gravity retaining wall structures.

[0007] Further, a road surface drainage trough is opened on the side of the main slope support structure away from the auxiliary slope support structure and communicated with the water guide trough.

[0008] Further, drainage outlets are respectively opened between the water guide trough of the support frame and the main slope support structure as well as the auxiliary slope support structure.

[0009] Further, a water guide frame is arranged on the side of the auxiliary slope support structure away from the main slope support structure, and the water guide trough at the top end of the auxiliary slope support structure is opened on the water guide frame.

[0010] Furthermore, the secondary slope support structure is provided with a side bearing structure at the bottom of the water guide frame on the side away from the main slope support structure.

[0011] Furthermore, the vegetation and soil layer between the main slope support structure and the secondary slope support structure is lower than the support frame.

[0012] This utility model addresses the limitations of traditional slope seepage prevention structures in terms of support strength and drainage effect, as well as the problems that existing seepage prevention structures rely on water guide channels but fail to effectively solve the problems of insufficient support strength and low drainage efficiency. It proposes a seepage prevention structure for geotechnical engineering.

[0013] This structure enhances overall support strength by setting up a main slope support structure and a secondary slope support structure, and using steel reinforcement connecting structures and an external cast-in-place support frame. At the same time, the main slope support structure, the secondary slope support structure, and the water guide channel opened at the top of the support frame are connected in sequence. Combined with the design of road drainage channels, drainage outlets, and water guide frames, the drainage capacity is effectively improved. Under complex geological conditions and extreme weather conditions, this structure can significantly improve the overall stability of the slope structure and reduce safety hazards such as landslides or collapses.

[0027] Example 1

[0028] like Figure 1-3 As shown, this utility model provides a technical solution: a seepage-proof structure for geotechnical engineering, including a main slope support structure 1, and a secondary slope support structure 2 at the end of the slope away from the road surface of the main slope support structure 1. The two together constitute the main support system for slope protection. Several steel reinforcement connection structures 3 are inclinedly arranged between the top of the main slope support structure 1 and the secondary slope support structure 2. These steel reinforcement connection structures 3 are evenly distributed and play a role in stabilizing the connection between the main and secondary slope support structures, thereby enhancing the stability of the overall structure. A support frame 4 is poured around the steel reinforcement connection structure 3. The support frame 4 is made of high-strength concrete, which further enhances the support strength of the entire structure. Water guide channels 5 are opened at the top of the main slope support structure 1, the secondary slope support structure 2 and the support frame 4. The main slope support structure 1, the support frame 4 and the secondary slope support structure 2 are connected in sequence to form a complete water guide channel so as to drain the water accumulated on the slope in a timely manner.

[0029] Example 2

[0030] like Figure 1-3 As shown, the main slope support structure 1 and the secondary slope support structure 2 are gravity retaining wall structures. This type of structure relies on its own weight to resist the lateral pressure of the soil and has the advantages of simple structure, convenient construction and good stability.

[0031] The main slope support structure 1 is connected to the water channel 5 on the side away from the secondary slope support structure 2, and a road surface drainage channel 11 is provided. The road surface drainage channel 11 is connected to the water channel 5, which can introduce the water accumulated on the road surface into the water channel 5 to avoid the water accumulation on the road surface from eroding the slope structure.

[0032] Drainage outlets 12 are provided between the water guide channel 5 of the support frame 4 and the main slope support structure 1 and the secondary slope support structure 2. The size and number of drainage outlets 12 are designed according to the actual drainage needs to ensure that the accumulated water can flow smoothly from the water guide channel 5 of the support frame 4 into the water guide channels 5 of the main and secondary slope support structures.

[0033] The secondary slope support structure 2 is provided with a water guide frame 21 on the side away from the main slope support structure 1. The water guide frame 21 is made of concrete and is easy to guide water flow. The water guide channel 5 at the top of the secondary slope support structure 2 is opened on the water guide frame 21, so that the accumulated water can flow smoothly into the water guide channel 5 along the water guide frame 21.

[0034] The secondary slope support structure 2 is located at the bottom of the water guide frame 21 on the side away from the main slope support structure 1, and the side bearing structure 22 supports the secondary slope support structure 2 and the water guide frame 21, thereby enhancing the stability of the water guide frame 21 and the secondary slope support structure 2.

[0035] The vegetation and soil layer 6 between the main slope support structure 1 and the secondary slope support structure 2 is lower than the support frame 4 to avoid soil blocking the water channel 5 on the support frame 4.

[0036] The workflow of this utility model is as follows: When using a seepage-proof structure for geotechnical engineering, the main slope support structure 1 is constructed first; appropriate construction methods are adopted, such as layered concrete pouring, to ensure that the strength and stability of the main slope support structure 1 meet the design standards; during the construction process, the quality of the concrete and the pouring process must be strictly controlled to ensure the quality of the main slope support structure 1.

[0037] Next, install the steel reinforcement connection structure 3. Install the pre-fabricated steel reinforcement connection structure 3 according to the designed position and angle, ensuring a firm connection between the steel reinforcement connection structure 3 and the main slope support structure 1. After the steel reinforcement connection structure 3 is installed, proceed with the pouring of the support frame 4. Erect formwork around the steel reinforcement connection structure 3, then pour high-strength concrete to form the support frame 4. During the pouring of the support frame 4, ensure thorough compaction to avoid quality problems such as honeycomb or pitted surfaces.

[0038] While the main slope support structure 1 and support frame 4 are being constructed, the secondary slope support structure 2 is being constructed. The secondary slope support structure 2 also adopts a gravity retaining wall structure, and the construction method is similar to that of the main slope support structure 1. On the side of the secondary slope support structure 2 away from the main slope support structure 1, the water guide frame 21 and the side bearing structure 22 are poured to ensure that the water guide frame 21 is firmly installed and the tilt angle meets the design requirements.

[0039] During the construction of the main and secondary slope support structures and support frame 4, water guide channels 5 are reserved at the top of the main slope support structure 1, the secondary slope support structure 2 and the support frame 4, and it is ensured that the water guide channels 5 are connected in sequence.

[0040] Meanwhile, a road surface drainage ditch 11 is opened on the side of the main slope support structure 1 away from the secondary slope support structure 2, and a drainage outlet 12 is reserved between the water guide ditch 5 of the support frame 4 and the main slope support structure 1 and the secondary slope support structure 2.

[0041] Finally, a vegetation soil layer 6 is laid between the main slope support structure 1 and the secondary slope support structure 2. Care should be taken to control the height of the vegetation soil layer 6 to be lower than that of the support frame 4. After the laying is completed, vegetation is planted and maintained to ensure that the vegetation can grow normally and further enhance the stability of the slope.

[0042] During daily use, when it rains, the water on the road surface flows into the water guide channel 5 of the main slope support structure 1 through the road drainage channel 11, and then passes through the water guide channel 5 of the support frame 4, the drainage outlet 12 and the water guide channel 5 of the secondary slope support structure 2 in sequence, and finally is discharged from the slope area through the water guide frame 21. At the same time, the water on the slope will also flow directly into the water guide channel 5 and be discharged along the water guide channel, which effectively avoids the accumulation of water on the slope and improves the stability and safety of the slope structure.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
