Description
Technical Field
[0001] The utility model relates to the technical field of slope reinforcement, in particular to a geotechnical engineering slope deformation reinforcement device. Background Art
[0002] Due to rainfall infiltration, long-term traffic loads, earthquakes, artificial excavation and other reasons, the original rock and soil slopes are prone to landslides and collapses due to deformation or sliding of the slope body, which becomes a serious natural disaster. For this reason, these slopes need to be reinforced. In the prior art, some rock and soil slopes are reinforced by using slope angle retaining walls. Retaining walls or supporting structures are set at specific parts of the slope to prevent the movement of soil or rock. However, this kind of retaining wall is also very dependent on the surrounding geology. After the above reasons accumulate, the stability of the traditional slope angle retaining wall may be insufficient, and it is easy to be impacted by the pressure of the rock and soil slope, resulting in structural failure. Utility Model Content

[0028] Please refer to Figure 1, this embodiment provides a geotechnical engineering slope deformation reinforcement device, which includes a retaining wall 1, multiple groups of anti-slide piles 3, multiple vertical cables 4, multiple oblique cables 5 and a tension sensor 7. The bottom of the retaining wall 1 is fixedly connected with a support plate 2. The support plate 2 and the retaining wall 1 form an inverted T-shaped structure as a whole. At the same time, the support plate 2 is buried in the rock and soil when in use, and the parts on both sides of the support plate 2 that exceed the retaining wall 1 are embedded in the rock and soil, so that one side of the retaining wall 1 is more stable and not easy to fall when it receives the pressure of the rock and soil slope. Furthermore, an inclined surface is set on the side of the retaining wall 1 away from the rock and soil slope, so that the cross-section of the retaining wall 1 is a right-angled trapezoid. The lower bottom length of the right-angled trapezoid retaining wall 1 is greater than the upper bottom length, which strengthens the structural strength of the retaining wall 1 body. On the other hand, a plurality of evenly distributed and vertically arranged ribs 6 are set on the side of the retaining wall 1 facing the rock and soil slope, which further strengthens the structural strength of the retaining wall 1, so that it has better stability when facing the pressure of the slope. Multiple groups of anti-slip piles 3 are arranged on the slope. The cross-sectional shape of the anti-slip piles 3 can be selected as any one of rectangular, circular, cross-shaped or I-shaped. According to the length of the retaining wall 1, the number of groups of anti-slip piles 3 is at least three, and the distance between each group of anti-slip piles 3 is evenly distributed. In order to ensure the use strength of the anti-slip piles 3, the number of anti-slip piles 3 in each group also needs to be at least two, and the multiple anti-slip piles 3 in the same group are distributed along the direction perpendicular to the retaining wall 1. The tops of the anti-slip piles 3 in the same group are fixedly connected to the same vertical cable 4. One end of the vertical cable 4 is fixedly connected to the top of the retaining wall 1, and the projection of the tension direction of the vertical cable 4 on the horizontal plane is perpendicular to the retaining wall 1, so that the anti-slip piles 3 in the same group form a whole with the retaining wall 1. Each group of anti-slip piles 3 is arranged in the same way, and they are connected to the retaining wall 1 through the same vertical cable 4. The anti-slide piles 3 not only stabilize the slope, but also provide a portion of pulling force to the retaining wall 1 , and cooperate with the support plate 2 at the bottom of the retaining wall 1 to further enhance the stability of the retaining wall 1 .
[0029] The oblique cables 5 are used to connect the anti-slip piles 3 to each other, so as to strengthen the connection between the multiple groups of anti-slip piles 3. Figure 2 As shown (top view), the anti-slip piles 3 between two adjacent groups are aligned in sequence. At this time, one end of the oblique cable 5 is connected to one of the anti-slip piles 3, and the other end is connected to the anti-slip pile 3 that is sequentially adjacent to the anti-slip pile 3 in the other group. For example, one end of the oblique cable 5 is fixedly connected to the anti-slip pile No. 2 in one group, and the other end is fixedly connected to the anti-slip pile No. 1 or No. 3 in an adjacent group. According to this rule, multiple oblique cables 5 are arranged so that all the anti-slip piles 3 form a network as a whole to support the sliding force of the slope and stabilize the slope. At the same time, the network as a whole can provide greater pulling force to the retaining wall 1 to help the retaining wall 1 remain stable. In another embodiment, as Figure 3As shown (top view), the anti-slip piles 3 between two adjacent groups are arranged in sequence and staggered. At this time, the two ends of the oblique cable 5 are respectively connected to the anti-slip piles 3 of the same order in the two groups of adjacent anti-slip piles 3. After arranging multiple oblique cables 5 according to this rule, all anti-slip piles 3 can form a network as a whole to play the above-mentioned role. The tension sensor 7 is arranged on one of the vertical cables 4 to detect the tension of the vertical cable 4. The tension sensor 7 can be a conventional model in the engineering industry, and its measurement principle and specific installation method will not be described in detail. The measured tension information can be remotely sent to relevant technical personnel through communication equipment, and the deformation of the rock and soil slope can be preliminarily known by analyzing the changes in the tension information. In order to ensure the normal use of the tension sensor 7, a small solar panel charging module can also be set near the tension sensor 7 to power the tension sensor 7 and the communication equipment. Since the power consumption of the sensor is generally small, and the communication equipment can be set to send at a fixed time. The solar panel charging module is fully capable of providing electrical energy.
[0030] like Figure 4 As shown, when the reinforcement device is in use, the retaining wall 1 is set at the slope corner, and the support plate 2 is buried in the soil. The anti-slip piles 3 are buried in the slope in sequence according to their existing operation mode to play a stabilizing role. Then the vertical cables 4 and the oblique cables 5 are connected in sequence. All the installed vertical cables 4 and oblique cables 5 maintain a certain tension at the beginning, so that the anti-slip piles, the retaining wall and the cables form a whole. According to the actual site conditions and engineering analysis, the relevant connection positions of the vertical cables 4 and the oblique cables 5 can be adjusted. That is, the connection point between the vertical cables 4 and the retaining wall 1 can be located at the top, or at a distance from one end below the top, etc. The vertical cables 4 and the oblique cables 5 can be exposed on the slope or buried in the soil.
[0031] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-described embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
