Description

Technical Field

[0001] The utility model relates to the technical field of slope support, in particular to a supporting device for preventing high slope from collapsing. Background Art

[0002] With the rapid development of infrastructure construction, high slope projects are increasingly appearing in the fields of transportation, water conservancy and urban construction. High slopes are prone to collapse during construction and later use, causing casualties and property losses, so the support requirements for high slopes are extremely strict. Although existing support technologies such as anchor rods, shotcrete mesh, lattice beams, etc. provide slope stability to a certain extent, they often have problems such as high cost, complex construction, and poor adaptability.

[0003] The patent with publication number CN117721822A discloses a prefabricated support structure and construction method for high slopes of water conservancy and hydropower projects. The anchor pier concrete precast panels and ordinary concrete precast panels used in the patent are prefabricated products that can shorten the on-site construction period, ensure the quality of concrete, and achieve rapid support of broken rock slopes. However, the anchor pier concrete precast panels and ordinary concrete precast panels are only connected in the vertical direction of the slope, and cannot jointly resist slope deformation in the vertical height. In the horizontal direction, they need to be connected by cast-in-place concrete belts. During the on-site construction process, more cast-in-place concrete operations are still required, and more on-site construction operations are still required.

[0004] In view of this, how to improve the current situation in which the high slope prefabricated support structure in the existing technology cannot jointly resist slope deformation in the vertical direction and has a long construction period has become a technical problem that technical personnel in this field urgently need to solve.

The middle of the first side wall 5 and the two ends of the second side wall 9 extend in directions away from each other to form a first protrusion 6 and two second protrusions 10. The first side walls 5 located on both sides of the first protrusion 6 are configured as a recessed structure, and the second side wall 9 located between the two second protrusions 10 is also configured as a recessed structure. In the present utility model, the support plates 2 located at the same horizontal position are defined as the same layer, and two adjacent support plates 2 of the same layer are spliced ​​together. The support plates 2 located at different horizontal positions are defined as different layers. The support plates 2 of adjacent layers are support plates 2 at different horizontal positions and arranged adjacently. The support plates 2 of adjacent layers are spliced ​​and connected to each other through multiple first protrusions 6 or multiple second protrusions 10. Figure 2 For example, the first raised portion 6 of the middle layer support plate 2 is connected to the depression between the first raised portions 6 of the two adjacent support plates 2 of the next layer, and the second raised portions 10 of the two adjacent support plates 2 of the middle layer are connected to the depression between the two second raised portions 10 of the same support plate 2 of the previous layer.

[0029] The support plate 2 of the utility model is connected to two support plates 2 of different layers respectively through the first protrusion 6 and the second protrusion 10, thereby realizing the connection between two adjacent support plates 2 between adjacent layers and different layers, that is, the connection in the horizontal direction and along the slope direction is realized at the same time, and the support plates 2 on the slope surface of the high slope 1 are connected to form a whole, which can achieve the effect of several support plates 2 jointly resisting slope deformation.

[0030] Reference Figure 3-4 The support plate 2 of the utility model is a reinforced concrete plate, and a plurality of longitudinal steel bars 3 are arranged in the support plate 2. The longitudinal steel bars 3 are arranged at equal intervals in the transverse direction, and a part of the longitudinal steel bars 3 protrudes from the first protrusion 6 to form a first connecting rod 7. The first side wall 5 located on both sides of the first protrusion 6 is embedded with a first grouting sleeve 8, and the first connecting rod 7 is matched with the first grouting sleeve 8. The support plate 2 of the middle layer and the support plate 2 of the next layer are connected by grouting after the first connecting rod 7 is embedded in the first grouting sleeve 8. In addition, another part of the longitudinal steel bars 3 protrudes from the second protrusion 10 to form a second connecting rod 11, and the second side wall 9 located between the two second protrusions 10 is embedded with a second grouting sleeve 12, and the second connecting rod 11 is matched with the second grouting sleeve 12. The support plate 2 of the middle layer and the support plate 2 of the upper layer are connected by grouting after the second connecting rod 11 is embedded in the second grouting sleeve 12.

[0031] Specifically, a plurality of transverse reinforcements 4 are arranged at intervals in the support plate 2, and the transverse reinforcements 4 are arranged perpendicular to the longitudinal reinforcements 3. The support plate 2 of the utility model is prefabricated in a factory, during which the transverse reinforcements 4 are tied and connected with the longitudinal reinforcements 3, and then concrete is poured to form the reinforcements.

The cross section of the first raised portion 6 along the vertical direction is an isosceles trapezoid, and the cross section of the second raised portion 10 along the vertical direction is a right-angled trapezoid.

[0033] Optionally, due to the manufacturing error of the precast concrete slab mold, the deformation of the mold during use, and the different strength of the upper and lower surfaces of the mold, the size of the produced reinforced concrete slab is deviated. When paving the support plates 2, a certain gap must be left between the support plates 2 to achieve a flat surface and a straight line.
