Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction foundation pit slope reinforcement device. Background Art

[0002] The slope of a construction pit refers to the sidewalls of the space formed by excavation below ground level during construction. The stability of the pit slope is crucial to construction safety. An unstable slope can cause collapse, damage the building, and even endanger the lives of workers.

However, the soil at different depths has different inherent softness, and the volume changes when compacted to the same state are different. Compacting the slope with a vertical plate will result in the upper soil layer not being compacted properly. In addition, the different softness of the upper and lower soil layers can easily lead to cracks on the slope surface. Utility Model Content

[0030] Combine Figures 1 to 5 As shown, the utility model provides a construction foundation pit slope reinforcement device comprising a reinforcement head 1 and a balancing component 2.

[0031] Combine Figures 1 to 5 As shown, the reinforcement head 1 includes a reinforcement plate 11, a first transmission rod 12 and a hydraulic cylinder 13, the driving end of the hydraulic cylinder 13 is fixedly connected to the first transmission rod 12, and the hydraulic cylinder 13 pushes the reinforcement plate 11 in the horizontal direction through the first transmission rod 12; the balancing assembly 2 includes a balancing rod 21 and a second transmission rod 22, the balancing rod 21 is parallel to the reinforcement plate 11, and there are two second transmission rods 22. The reinforcement plate 11, the second transmission rod 22 and the balancing rod 21 are rotated and connected in sequence to form a parallelogram, the first transmission rod 12 is located between the two second transmission rods 22, and the two ends of the first transmission rod 12 are respectively rotated to connect the reinforcement plate 11 and the middle section of the balancing rod 21; after the reinforcement plate 11 contacts the soil, the reinforcement plate 11 tilts to the side with less force on the soil due to the deformation of the balancing assembly 2.

[0032] In this embodiment, the balancing component 2 and the reinforcement head 1 form a parallelogram, and the deformation process of the parallelogram is used to adjust the compaction depth difference between the upper and lower layers of soil; the balancing rod 21 transmits the compaction force up and down, ensures the uniformity of the compaction force, achieves a uniform compaction effect, effectively avoids the cracking of the slope, and improves the stability of the slope.

[0033] In some embodiments, combined Figure 2As shown, the construction foundation pit slope reinforcement device also includes a support member 3, which includes a support plate 31, a positioning frame 32 and a fixing frame 33. The positioning frame 32 and the fixing frame 33 are fixedly connected to the support plate 31. A positioning hole is provided on the positioning frame 32. The first transmission rod 12 is slidably assembled in the positioning hole. The hydraulic cylinder 13 is fixedly connected to the fixing frame 33. The support member 3 is used to fix the reinforcement head 1 and the balancing assembly 2. At the same time, the support member 3 can be equipped with wheels or installed on a device with mobility.

[0034] In some embodiments, combined Figure 3 As shown, there are three positioning holes on the positioning frame 32, and the first transmission rod 12 and the two second transmission rods 22 are respectively slidably assembled in the three positioning holes. The second transmission rod 22 is connected to the reinforcement plate 11 and the balance rod 21 through a rotating shaft. Extension grooves are provided on the reinforcement plate 11 and the balance rod 21, and the second transmission rod 22 is slidably assembled in the extension grooves. The movement process of the reinforcement head 1 and the balance component 2 is reinforced through the three positioning holes, which improves the force-bearing capacity of the equipment. At the same time, the three positioning holes fix the distance between the first transmission rod 12 and the two second transmission rods 22, and the jamming phenomenon is avoided by designing the extension grooves.

[0035] In some embodiments, combined Figure 3 As shown, there are three hydraulic cylinders 13 fixedly connected to the fixed frame 33, and the driving ends of the three hydraulic cylinders 13 are respectively facing the three positioning holes. The driving ends of the three hydraulic cylinders 13 are respectively fixedly connected to the first transmission rod 12 and the two second transmission rods 22. The compaction ability of the device is improved by providing power through the three hydraulic cylinders 13. At the same time, more complex compaction tasks can be completed by independently controlling the three hydraulic cylinders 13.

[0036] In some embodiments, combined Figure 3 As shown, the three hydraulic cylinders 13 are connected to the same hydraulic system, which simplifies the control process and reduces the production cost of the device.

[0037] In some embodiments, combined Figure 4 As shown, the reinforcing plate 11 is an arc-shaped plate, and the upper end of the reinforcing plate 11 is bent away from the first transmission rod 12. During the compaction process by the arc-shaped reinforcing plate 11, there is a downward offset compaction effect on the upper soil, which can effectively prevent the upper soil from bulging during the compaction process.

[0038] In some embodiments, combined Figure 4As shown, the lower end of the reinforcement plate 11 is integrally formed with a lever plate 14, and the lever plate 14 is bent in the direction away from the first transmission rod 12. During the compaction process, the reinforcement plate 11 is deflected, resulting in tangential force during the compaction process, thereby causing problems such as slipping and affecting the compaction effect. The lever plate 14 can offset the existence of the tangential force and achieve a better compaction effect.

[0039] In some embodiments, combined Figure 4 As shown, a positioning protrusion 15 is integrally formed on the surface of the reinforcement plate 11 away from the first transmission rod 12. The positioning protrusion 15 is evenly distributed on the surface of the reinforcement plate 11. The positioning protrusion 15 can increase the friction between the two when the reinforcement plate 11 contacts the soil, thereby avoiding slipping.

[0040] In some embodiments, combined Figure 5 As shown, the construction foundation pit slope reinforcement device also includes a casting trough strip 16, which is fixedly connected to the surface of the reinforcement plate 11 away from the first transmission rod 12. The side of the casting trough strip 16 is perpendicular to the surface of the reinforcement plate 11. By adding the casting trough strip 16, a casting trough can be formed on the soil surface after compaction, and the subsequent pouring of quick-drying cement can effectively increase the stability of the slope.

[0041] In some embodiments, combined Figure 5 As shown, the casting trough strips 16 are fixedly connected to the reinforcement plate 11 in a mesh shape that is staggered horizontally and vertically. The casting troughs that are staggered horizontally and vertically in a mesh shape can better fix the soil and effectively avoid the occurrence of collapse and the like.

[0042] Working process: After the reinforcement plate 11 hits the soil, the upper and lower layers of the soil exert different reaction forces on the reinforcement plate 11 due to their different softness. When the reaction force of the lower layer of the soil is larger, the reaction force of the lower layer of the soil is transmitted to the upper half of the reinforcement plate 11 through the second transmission rod 22, the balance rod 21 and the upper second transmission rod 22, and finally applied to the upper layer of soil; the upper layer of soil is quickly compacted until the softness of the upper and lower layers of soil is the same.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
