A prefabricated frame structure for slope protection

Abstract

The present invention discloses a prefabricated frame structure for slope protection, which relates to the technical field of slope protection, and aims to solve the technical problem that the existing prefabricated frame structure as a whole is a fixed template that is not easy to adjust, including an outer surrounding support mechanism. The present invention uses an outer surrounding support mechanism and an auxiliary filling and forming mechanism composed of two groups of scissor-type folding structures to adjust each other. In this way, different casting and forming operations can be performed on the sections with rapid water flow and the sections with slow water flow in the water conservancy project, respectively, to adapt to the scouring and erosion adaptation effects caused by different water flow sections on the slopes. In the sections with rapid water flow, a slope with a large cross section is used to adapt to the scouring and erosion of the water flow. At the same time, the mass of the section relative to the unit area can effectively bear the scouring force of the water flow. In the sections with slow water flow, a slope with a small cross section is used to adapt to the scouring and erosion of the water flow. At the same time, the axial length in a single casting process is effectively increased to improve the casting efficiency.

Description

Technical Field

[0001] The invention relates to the technical field of slope protection, and more specifically to a prefabricated frame structure for slope protection. Background Art

[0002] Prefabricated frame structure for slope protection is an efficient slope support technology, which uses prefabricated components to build a support structure on the slope to improve the stability of the slope and construction efficiency. The following is a detailed analysis of the prefabricated frame structure for slope protection:

[0003] Structural features

[0004] Durability: Prefabricated frame structures are usually made of high-strength, corrosion-resistant materials such as reinforced concrete, so they have high durability and stability and can withstand loads such as slope ground stress and groundwater pressure for a long time.

[0005] Flexibility: The prefabricated frame structure can be customized and adjusted according to the shape, size and geological conditions of the slope to adapt to different types of slope projects. At the same time, the connection methods between prefabricated components are also varied, such as bolt connection, welding, etc., which is convenient for construction and installation.

[0006] Convenient construction: Using prefabricated frame structure for slope protection can greatly shorten the construction period and improve construction efficiency. This is because prefabricated components can be manufactured in advance in the factory, and only assembly and debugging are required on site.

[0007] Environmental protection: Prefabricated frame structures generate less waste during the construction process, and can be filled and reinforced on-site with stones, sand and other materials, which is beneficial to the protection and restoration of the ecological environment.

[0008] Currently, most protective slopes cast with reinforced concrete are cast on-site through prefabricated fixed prefabricated templates. The overall structure is fixed and cannot be effectively adjusted to the actual geographical environment. Therefore, it is particularly important to propose a prefabricated frame structure that is easy to adjust. In view of this, we propose a prefabricated frame structure for slope protection.

[0018] S100: First-level adjustment processing:

[0019] For example Fig.11 The adjustment treatment of the rectangular serrated foundation pier casting shown in the figure:

[0020] First, the tool is used to rotate and adjust the screw rod so that the hinge seat on the connecting arm is at the same height as the hinge seat at the relative position; then the tool is used to rotate and drive the screw rod so that the two hinge seats distributed up and down are synchronously moved relatively close to each other, so that the scissor-type connecting rod assembly and the synchronous connecting rod assembly are synchronously stretched and unfolded relatively, and the force-bearing folding surrounding frame assembly A and the force-bearing folding surrounding frame assembly B are synchronously unfolded relatively, so that the cross-sectional area of ​​the auxiliary filling and molding mechanism in a top-view angle is increased;

[0021] S200: One-stage casting:

[0022] Tie up the steel bar frame, then pour an appropriate amount of cement mortar into the auxiliary filling and forming mechanism to solidify and form the foundation pier.

[0023] S300: Secondary adjustment processing:

[0024] For example Fig.11 The right-angled trapezoidal guard block with serrated shape shown is cast in place for adjustment:

[0025] First, the tool is used to rotate and drive the screw rod so that the two articulated seats distributed up and down in multiple groups move away from each other synchronously, so that the scissor-type connecting rod assembly and the synchronous connecting rod assembly are synchronously compressed relatively, and the force-bearing folding surrounding frame assembly A and the force-bearing folding surrounding frame assembly B are synchronously compressed relatively, so that the cross-sectional area of ​​the auxiliary filling and molding mechanism is reduced in a top-view angle; then, the tool is used to rotate and adjust the screw rod so that the articulated seat on the connecting arm has a height difference with the articulated seat in the relative position, so that the force-bearing folding surrounding frame assembly A on one side is tilted, and the pull-out plate is adjusted to be tilted synchronously;

[0026] S400: Secondary casting process:

[0027] The adjusted prefabricated frame structure is placed on the upper surface of the foundation pier in the first-level pouring molding in S200 through an auxiliary frame; then a proper amount of cement mortar is poured into the auxiliary filling molding mechanism, so that it solidifies and forms a protective block;

[0028] S500: Based on the secondary adjustment process of S300, it is lifted through the auxiliary frame, and then the auxiliary support plate is manually rotated and pulled by the synchronous rod or several of them are independently moved to partially overlap the tooth grooves of the foundation pier. The bottom of the inclined surface of the protective block is filled by moving the auxiliary support plate to narrow the gap. This structural setting can avoid cement leakage during the cement pouring process.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention cooperates with each other through the outer surrounding support mechanism and the auxiliary filling and forming mechanism composed of two groups of scissor-type folding structures. By adjusting the upper and lower approaches, the prefabricated frame structure as a whole is relatively expanded. The prefabricated frame structure in this state is used to carry out the foundation pier with a relatively large cross-section and a number of protective blocks continuously arranged on the foundation pier. By adjusting the upper and lower distances, the prefabricated frame structure as a whole is relatively compressed. The prefabricated frame structure in this state is used to carry out the foundation pier with a relatively small cross-section and a number of protective blocks continuously arranged on the foundation pier. In this way, different casting and forming operations can be performed on the sections with rapid water flow and the sections with slow water flow in the water conservancy project respectively, so as to adapt to the scouring and erosion adaptation effects caused by different water flow sections on the slopes. In the sections with rapid water flow, the slopes with large cross-sections are used to adapt to the scouring and erosion of the water flow. At the same time, the mass of the section relative to the unit area can effectively bear the scouring force of the water flow. In the sections with slow water flow, the slopes with small cross-sections are used to adapt to the scouring and erosion of the water flow. At the same time, the axial length in a single casting process is effectively increased to improve the casting efficiency.

[0031] 2. The present invention can tilt the connecting arm by rotating the adjusting screw rod, so that the internal casting cavity of the auxiliary filling and molding mechanism changes from an overall cubic shape to a right-angled trapezoidal shape. Through this arrangement, the prefabricated frame structure can be cast into a foundation pier and a plurality of protective blocks continuously arranged on the foundation pier.

[0032] 3. In the present invention, the casting cavity inside the auxiliary filling and molding mechanism is changed from an overall cubic shape to a right-angled trapezoidal shape. The force-bearing folding surrounding frame assembly B can be horizontally pulled and adjusted based on the movable connection between the folding plate and the adjustable pull-out plate. With the setting of the beveled surface, the adjustable pull-out plate can be folded and contracted to adjust the angle. The surrounding base plate A and the surrounding base plate B are folded up and down, so that the edge of the slope pier has a tooth groove, which effectively increases the contact and connection area between the edge of the slope pier and the slope soil layer of the water conservancy project through the tooth groove, thereby further improving the stability of the slope pier during use.

[0033] 4. The scissor-type folding structure formed by hingedly setting a plurality of linkage links and the surrounding base plate A and the surrounding base plate B can effectively maintain uniform distribution of the tooth grooves during the folding adjustment process, thereby facilitating the formation of the tooth grooves during the casting process.

[0034] 5. The present invention limits the sliding of the rotating base rod seat relative to the guide bolt located at a high position, so as to cooperate with the linkage connecting rod to synchronously and equidistantly unfold the surrounding substrate A and the surrounding substrate B. While facilitating the unfolding and compression and folding operations, it effectively enables the surrounding substrates A and B to maintain a good adjustment angle, which is convenient for the formation of tooth grooves during the casting process.

[0035] 6. The present invention manually rotates the auxiliary supporting plate to the outside to adapt to the casting of the auxiliary filling and molding mechanism's internal casting cavity, which is an overall cubic foundation pier and the first protective block. By pulling and rotating the synchronization rod, multiple auxiliary supporting plates can be synchronously used to fill the bottom of the inclined surface of the protective block to reduce the contact gap. This optimized structural setting prevents cement from leaking out during the cement pouring process. BRIEF DESCRIPTION OF THE DRAWINGS

The present invention cooperates with each other through an outer surrounding support mechanism 1 and an auxiliary filling and forming mechanism 2 composed of two groups of scissor-type folding structures. By adjusting the upper and lower approaches, the prefabricated frame structure as a whole is relatively expanded. The prefabricated frame structure in this state is used to carry out foundation piers with relatively large cross-sections and a number of protective blocks continuously arranged on the foundation piers. By adjusting the upper and lower distances, the prefabricated frame structure as a whole is relatively compressed. The prefabricated frame structure in this state is used to carry out foundation piers with relatively small cross-sections and a number of protective blocks continuously arranged on the foundation piers. In this way, different casting and forming operations can be performed on the sections with rapid water flow and the sections with slow water flow in water conservancy projects, respectively, to adapt to the scouring and erosion adaptation effects of different water flow sections on the slopes. In the sections with rapid water flow, the slopes with large cross-sections are used to adapt to the scouring and erosion of the water flow. At the same time, the mass of the section relative to the unit area can effectively bear the scouring force of the water flow. In the sections with slow water flow, the slopes with small cross-sections are used to adapt to the scouring and erosion of the water flow. At the same time, the axial length in a single casting process is effectively increased to improve the casting efficiency.

Figure 6As shown, by rotating the screw rod 404, the connecting arm 405 can be tilted, so that the internal casting cavity of the auxiliary filling and molding mechanism 2 changes from the overall cubic shape to a right-angled trapezoidal shape. Through this setting, the prefabricated frame structure can be cast into the following shapes: Fig.11 The shown foundation pier and several protective blocks continuously arranged on the foundation pier.

[0055] In an embodiment of the present invention, the auxiliary filling and molding mechanism 2 includes two horizontally arranged force-bearing folding surrounding frame components A201 and force-bearing folding surrounding frame components B202 arranged on both sides of the force-bearing folding surrounding frame components A201; wherein, the top of the force-bearing folding surrounding frame components A201 is provided with a linkage connecting rod 203; and, the force-bearing folding surrounding frame components A201 are composed of at least one folding force-bearing unit; the folding force-bearing unit includes two rotating base rod seats 205; the rotating base rod seat 205 is arranged inside the outer surrounding support mechanism 1; and, the two rotating base rod seats 205 are hingedly and alternately provided with surrounding substrates A2051 and surrounding substrates B2052; and, the middle ends of the tops of the surrounding substrates A2051 and B2052 are provided with central rotating convex shafts; wherein, the force-bearing folding surrounding frame components B2 02 includes a folding plate 2021 slidably arranged on the hooking protrusion 4011; and, the surface of the folding plate 2021 is provided with a hooking guide groove 2022 that slidably cooperates with the hooking protrusion 4011; wherein, the folding plate 2021 is provided with horizontal guide grooves 2023 at both ends; a horizontal pull-out plate 2024 with a rectangular structure is movably provided on one side of the folding plate 2021; and, the horizontal pull-out plate 2024 is provided with a positioning sliding protrusion 2025 relative to the horizontal guide groove 2023; wherein, an adjusting pull-out plate 2027 is movably provided on one side of the folding plate 2021, and the adjusting pull-out plate 2027 has a chamfered surface 2028 at one end relatively close to the folding plate 2021; and, a guiding positioning slide groove B2026 is provided at one end of the horizontal pull-out plate 2024 and the adjusting pull-out plate 2027 relatively far from the folding plate 2021.

Combined with the setting of the beveled surface 2028, the adjusting pull-out plate 2027 can be folded and contracted for angle adjustment, and the surrounding substrate A2051 and the surrounding substrate B2052 are folded up and down, so that the edge of the slope pier has a tooth groove, and the tooth groove effectively increases the contact and connection area between the edge of the slope pier and the slope soil layer of the water conservancy project, thereby further improving the stability of the slope pier during use.

[0056] In the embodiment of the present invention, a plurality of linkage links 203 are hinged in sequence, and the linkage links 203 are movably connected with the central rotating convex shaft so that the linkage links 203 and the surrounding substrate A 2051 and the surrounding substrate B 2052 form a scissor-type folding structure.

[0057] In the embodiment of the present invention, the adjustment pull-out plate 2027 and the horizontal pull-out plate 2024 are respectively connected to the rotating base rod seat 205 relatively close to one end of the force-bearing folding surrounding frame component B202 through the auxiliary connecting plate 206.

[0060] Working principle: A method for using a prefabricated frame structure for slope protection, comprising the following steps:

[0061] S100: First-level adjustment processing:

[0062] For example Fig.11 The adjustment treatment of the rectangular serrated foundation pier casting shown in the figure:

[0063] First, the tool is used to rotate and adjust the screw rod 404 so that the hinge seat 5 on the connecting arm 405 is at the same height as the hinge seat 5 at the relative position; then the tool is used to rotate and drive the screw rod 6 so that the two hinge seats 5 distributed up and down are synchronously moved relatively close to each other, so that the scissor-type connecting rod assembly 3 and the synchronous connecting rod assembly 4 are synchronously stretched and unfolded relatively, and the force-bearing folding surrounding frame assembly A201 and the force-bearing folding surrounding frame assembly B202 are synchronously relatively unfolded; so that the cross-sectional area of ​​the auxiliary filling and molding mechanism 2 is increased when viewed from above;

[0064] S200: One-stage casting:

[0065] Tie up the steel bar frame, then pour a proper amount of cement mortar into the auxiliary filling and forming mechanism 2, so that it solidifies and forms the foundation pier.

[0066] S300: Secondary adjustment processing:

[0067] For example Fig.11 The right-angled trapezoidal guard block with serrated shape shown is cast in place for adjustment:

[0068] First, the tool is used to rotate and drive the screw rod 6 so that the two articulated seats 5 distributed up and down in multiple groups are synchronously moved away from each other, so that the scissor-type connecting rod assembly 3 and the synchronous connecting rod assembly 4 are synchronously compressed, and the force-bearing folding surrounding frame assembly A201 and the force-bearing folding surrounding frame assembly B202 are synchronously compressed, so that the cross-sectional area of ​​the auxiliary filling and molding mechanism 2 is reduced in a top-view angle; then the tool is used to rotate and adjust the screw rod 404 so that the articulated seat 5 on the connecting arm 405 has a height difference with the articulated seat 5 in a relative position, so that the force-bearing folding surrounding frame assembly A201 on one side is tilted, and the pull-out plate 2027 is adjusted to be tilted synchronously;

[0069] S400: Secondary casting process:

[0070] The adjusted prefabricated frame structure is placed on the upper surface of the foundation pier in the primary casting molding in S200 through the auxiliary frame; then a suitable amount of cement mortar is poured into the auxiliary filling molding mechanism 2, so that it solidifies and forms a protective block;

[0071] S500: Based on the secondary adjustment process of S300, the auxiliary frame is used for lifting, and then the auxiliary support plate (209) is manually rotated and pulled to partially overlap the tooth groove of the foundation pier by pulling a plurality of the auxiliary support plates (209) or independently toggling them. The bottom of the inclined surface of the protection block is filled by toggling the auxiliary support plate (209) to narrow the gap. This structural setting prevents cement from leaking out during the cement pouring process.
