Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a pier mold, a retaining wall structure, and an anchor pile. Background Technology

[0002] The roadbed protection anchor pile pad is a tensioning platform set up on the pile body when prestressed anchor cables are installed. The center line of the top surface of the pad must be perpendicular to the axis of the anchor cable hole. The position and angle of the pad are subject to particularly strict requirements during construction. The allowable deviation in position is ±50mm, and the deviation in inclination angle is 1%. Therefore, the position and angle of the pad must be accurately positioned when constructing the roadbed protection anchor pile.

[0003] However, in the existing technology, the pad is a prefabricated product. The pad needs to be connected to the anchor pile through secondary splicing after the anchor pile is poured. This molding method results in severe delamination between the pad and the anchor pile, poor overall integrity, and the pad is prone to assembly deviation, which causes great difficulties for subsequent anchor cable pulling. Utility Model Content

[0004] The first aspect of this utility model provides a pier mold to solve the defect of delamination between the pier and the anchor pile in the prior art. By setting a pier mold with a flange, it can be set on the retaining wall body during construction, and then the pier and the anchor pile can be cast into an integral structure. In this way, it is not necessary to assemble the prefabricated pier again after the anchor pile is formed, so that delamination will not occur between the two, and the problem of assembly error that is easy to occur when the pier is assembled twice can be solved.

[0005] The second aspect of this utility model provides a protective wall structure.

[0006] The third aspect of this utility model provides an anchor pile.

[0007] The pier mold provided by this utility model includes: The mold body has a molding cavity for forming a pad, and a positioning hole is provided at the bottom of the molding cavity for anchor cable pulling; the opening of the molding cavity is provided with at least one flange, and the mold body is adapted to be fixed to the protective wall body by the flange; A limiting member is provided at the positioning hole, and the limiting member is used to guide and limit the pulling of the anchor cable.

The bottom wall, the first side wall, the second side wall, the third side wall and the fourth side wall together form the molding cavity. The positioning hole is located on the bottom wall.

[0010] According to the pad mold provided by this utility model, four flanges are provided, and the four flanges are respectively provided on the side of the first side wall, the second side wall, the third side wall and the fourth side wall away from the bottom wall.

[0011] According to the pad mold provided by this utility model, the four flanges are located on the same plane, and the bottom wall is arranged at a preset angle with the plane, the preset angle being α, where the value of α ranges from 24° to 30°.

[0012] The protective wall structure provided by this utility model includes a protective wall body and a pad mold as described in any of the preceding claims; The retaining wall body includes a first retaining wall, a second retaining wall, a third retaining wall, and a fourth retaining wall. The first retaining wall and the second retaining wall are arranged opposite to each other, and the third retaining wall and the fourth retaining wall are arranged opposite to each other between the first retaining wall and the second retaining wall. The first retaining wall, the second retaining wall, the third retaining wall, and the fourth retaining wall restrict a shaping space, which is used to form an anchor pile. The pier mold is embedded in at least one of the first protective wall, the second protective wall, the third protective wall, and the fourth protective wall, with the opening of the pier mold facing the shaping space.

[0013] This utility model provides an anchor pile manufactured from the aforementioned retaining wall structure, the anchor pile including a body, the surface of which is formed with protruding pads.

[0014] The anchor pile provided by this utility model also includes a guide steel pipe, which is inserted through the body and the pad, and is used to insert the anchor cable.

[0015] The anchor pile provided by this utility model also includes a positioning steel bar, which includes a first straight segment and a second straight segment. The first straight segment passes through the body and the pad, and the second straight segment is located at the end of the first straight segment facing the pad and is parallel to the bottom surface of the pad.

[0016] According to the anchor pile provided by this utility model, the anchor pile further includes a head end component, which is disposed on the side of the pad away from the main body, and the head end component is used to seal the anchor hole at the bottom of the pad.

[0017] The pier mold provided by this utility model has a mold body with a molding cavity and a flange at the opening of the mold body. In this way, the pier mold can be installed on the retaining wall body. Thus, when casting anchor piles, the pier and anchor piles can be cast into an integrated structure.

[0032] Figure 1 This is a side view of the pier mold provided in this embodiment of the utility model; Figure 2 This is a front view of the pier mold provided in this embodiment of the utility model.

[0033] See Figure 1 and Figure 2 The first aspect of this utility model provides a pier mold 24, which includes a mold body 240 and a limiting member 248. The mold body 240 has a molding cavity 247. In use, concrete or other materials are poured into the molding cavity 247, and the pier 12 is obtained after the concrete cools. The bottom of the molding cavity 247 is provided with a positioning hole 2421, which is used for anchor cable pulling. During construction, the position of the guide steel pipe 13 can be determined through the positioning hole 2421. That is, the guide steel pipe 13 needs to be aligned with the positioning hole 2421. For example, the guide steel pipe 13 can be riveted to the bottom wall 242 of the pier mold 24. The anchor cable is extended into the mountain on the other side of the anchor pile 10 through the guide steel pipe 13 and the positioning hole 2421, and the anchor cable is pulled.

[0034] The mold body 240 has at least one flange 241 at its opening. Specifically, during construction, the position of the pier mold 24 on the concrete of the retaining wall can be determined first according to the measurement and layout of the construction drawing. Then, using the pre-set anchoring holes on the flange 241 of the pier mold 24, the pier mold 24 is firmly connected to the reinforcing steel of the retaining wall with fasteners such as screws or bolts. After that, the retaining wall body 21 is formed by pouring concrete. During the construction of the retaining wall body 21, the pier mold 24 is filled and compacted with the surrounding concrete to obtain the retaining wall body 21 with the pier mold 24. The limiting member 248 is provided at the positioning hole 2421. The limiting member 248 is used to guide and limit the pulling of the anchor cable.

[0035] See Figure 1 and Figure 2It is understood that the pier mold 24 provided in this embodiment of the present invention, by setting a mold body 240 with a molding cavity 247 and setting a flange 241 at the opening of the mold body 240, can install the pier mold 24 on the retaining wall body 21. In this way, when casting the anchor pile 10, the pier 12 and the anchor pile 10 can be cast into an integral structure. The anchor pile 10 and the pier 12 of the integral structure have better strength, stronger bearing capacity and better overall integrity.

[0036] Compared to existing technologies, the pier mold 24 provided in this embodiment of the present invention, by setting the pier mold 24 with a flange 241, can be placed on the retaining wall body 21 during construction, thereby casting an integral structure of the pier 12 and the anchor pile 10. This eliminates the need for secondary assembly of the prefabricated pier 12 after the anchor pile 10 is formed, thus preventing delamination between the two and solving the problem of assembly errors that easily occur during secondary assembly of the pier 12, avoiding the impact of this problem on subsequent construction. Secondly, the setting of the limiting member 248 can effectively guide and limit the anchor cable during the pulling process, reducing the difficulty of anchor cable pulling and improving construction efficiency.

[0037] Continue reading Figure 1 In an optional embodiment of the present invention, the limiting member 248 includes a connecting pipe section 2481 and a cantilever section 2482. The connecting pipe section 2481 is connected to the positioning hole 2421. The cantilever section 2482 is connected to the side of the connecting pipe section 2481 away from the positioning hole 2421. The cantilever section 2482 includes multiple cantilevers, which are evenly spaced along the circumferential direction of the cantilever section 2482.

[0038] Understandably, the multiple cantilever arms have a certain amount of room to maneuver. This allows for fine-tuning of the guide pipe 13 during its fixing process. For example, if the guide pipe 13 deviates in one direction, it can be pulled in the opposite direction. During this process, the multiple cantilever arms have a certain elastic contraction capacity, which can compensate for the positional changes of the guide pipe 13 through their own deformation. Compared to a direct fixing method, this greater flexibility facilitates actual construction, making it easier for construction workers to set up the guide pipe 13, thereby improving construction efficiency.

[0039] Continue reading Figure 2In an optional embodiment of this utility model, the mold body 240 includes a bottom wall 242, a first side wall 243, a second side wall 244, a third side wall 245, and a fourth side wall 246. The first side wall 243 and the second side wall 244 are disposed opposite to each other on both sides of the bottom wall 242, and the third side wall 245 and the fourth side wall 246 are disposed opposite to each other between the first side wall 243 and the second side wall 244. A positioning hole 2421 is provided in the bottom wall 242. The bottom wall 242, the first side wall 243, the second side wall 244, the third side wall 245, and the fourth side wall 246 surround the aforementioned molding cavity 247. The shape of the molding cavity 247 corresponds to the shape of the pad 12 and can be adaptively adjusted according to actual needs.

[0040] The bottom wall 242, the first side wall 243, the second side wall 244, the third side wall 245, and the fourth side wall 246 can be independent plates, which reduces the manufacturing difficulty and facilitates the processing and manufacturing of the mold body 240. Of course, the bottom wall 242, the first side wall 243, the second side wall 244, the third side wall 245, and the fourth side wall 246 can also be made as a single piece, such as by casting, which reduces the assembly steps.

[0041] Continue reading Figure 2 In an optional embodiment of this utility model, four flanges 241 are provided. The four flanges 241 are respectively provided on the side of the first sidewall 243, the second sidewall 244, the third sidewall 245, and the fourth sidewall 246 away from the bottom wall 242. Taking the first sidewall 243 as an example, the flange 241 can be a folded plane formed by folding the first sidewall 243 outward, or the flange 241 can be obtained by splicing it with the first sidewall 243 through a plate. Specifically, it can be arranged adaptively according to the actual situation. The flanges 241 corresponding to the second sidewall 244, the third sidewall 245, and the fourth sidewall 246 are similar, and will not be described in detail here.

[0042] See Figure 2 It is understood that the pad mold 24 provided in this embodiment of the present invention has corresponding flanges 241 on the side of the first side wall 243, the second side wall 244, the third side wall 245 and the fourth side wall 246 away from the bottom wall 242. In this way, when installing the pad mold 24, the pad mold 24 can be firmly fixed to the protective wall body 21 by the four flanges 241, which can greatly improve the stability of the pad mold 24 and its integration with the protective wall body 21.

[0043] See Figure 1In an optional embodiment of this utility model, the four flanges 241 are located on the same plane, and the bottom wall 242 is arranged at a preset angle with the plane. The preset angle is α, where the value of α ranges from 24° to 30°. For example, α can be set to 24°, 26°, 28° or 30°. It is understood that the required angle of the pier 12 is different at different positions. By adaptively limiting the angle between the bottom wall 242 and the plane within the above-mentioned value range, the actual construction needs can be guaranteed. Compared with the secondary assembly method on site, the pier mold 24 provided by this utility model has a higher accuracy in the angle between the bottom wall 242 and the plane, which can ensure that the angle of the pier 12 after molding is more accurate.

[0044] Figure 3 This is a schematic diagram of the protective wall structure provided in an embodiment of the present invention from one perspective; Figure 4 This is a schematic diagram of the protective wall structure provided in an embodiment of the present invention from another perspective.

[0045] See Figure 3 and Figure 4 The second aspect of this utility model provides a retaining wall structure 20, which includes a retaining wall body 21 and a pier mold 24 as described in any of the foregoing embodiments. The retaining wall body 21 includes a first retaining wall 22, a second retaining wall 23, a third retaining wall, and a fourth retaining wall. The first retaining wall 22 and the second retaining wall 23 are arranged opposite to each other, and the third and fourth retaining walls are arranged opposite to each other between the first retaining wall 22 and the second retaining wall 23. The first retaining wall 22, the second retaining wall 23, the third retaining wall, and the fourth retaining wall enclose a shaping space 25, which is used to form an anchor pile 10. The pier mold 24 is embedded in at least one of the first retaining wall 22, the second retaining wall 23, the third retaining wall, and the fourth retaining wall, with the opening of the pier mold 24 facing the shaping space 25.

[0046] Specifically, before constructing the retaining wall structure 20, the interlocking construction needs to be carried out first. During the interlocking construction, the pile positions must be surveyed and marked out before the interlocking excavation is carried out. The principle of intermittent pile excavation must be followed during excavation; construction of adjacent pile positions can only proceed after the adjacent anchor piles 10 have been poured. The interlocking is constructed using C20 reinforced concrete. After the pile hole excavation is completed, the interlocking and retaining wall reinforcement should be tied immediately according to the design drawings. After inspection and acceptance to ensure compliance with design requirements, formwork should be erected, checked, and reinforced before constructing the interlocking and retaining wall structure 20 with concrete. The interlocking reinforcement can be centrally processed at the steel reinforcement processing plant and transported to the site by handcart for tying.

[0047] To facilitate construction, the retaining wall structure 20 can be divided into different construction segments along the length of the pile hole, such as the first segment and the second segment. Taking the first segment of the retaining wall structure 20 as an example, when excavating the pile hole, the soil and rock in the middle part of the pile hole are excavated first, and then the excavation is expanded to the periphery. The cross-sectional dimensions of the pile hole are controlled, and the height of the excavation segment is determined according to the different soil conditions. When the soil conditions are good, each segment can be excavated to a depth of 1m. When the soil layer is loose, the height of the excavation segment can be reduced to 0.5-0.8m.

[0048] During the excavation process, original records must be kept. If any changes in geological conditions are found, measures should be taken immediately in terms of construction technology and safety facilities. When several pile holes are excavated simultaneously, attention should be paid to the excavation sequence. Adjacent pile holes should not be excavated at the same time. They should be excavated in a skip manner, either by skipping piles or by skipping two piles. Excavation of adjacent piles can only begin when the concrete of the already poured piles has reached more than 75% of its design strength.

[0049] After the first section of the bored pile is excavated, a plumb bob is suspended at the intersection of the cross-shaped retaining piles. The plumb bob can be used to check the hole diameter, verticality, and center deviation to ensure that the center of the formed hole and the center of the pile are on the same vertical line. It should be noted that the retaining concrete must not encroach on the pile foundation concrete; otherwise, the next construction process cannot be carried out.

[0050] After the above construction steps are completed, the construction of the first section of the retaining wall structure 20 can begin. Specifically, the concrete is first centrally mixed at the mixing plant and then transported to the site. Steel composite formwork is used on site. Each section of the retaining wall structure 20 is 1-2m long. When the soil stability of the pile well wall is poor, sections of 0.5-1m are used. If necessary, the retaining wall structure 20 needs to be reinforced with denser reinforcement and thickened to ensure safety. The reinforcement of the retaining wall structure 20 can be installed using a pre-fabricated hole installation method in the processing area. The vertical reinforcement of the retaining wall structure 20 can be connected by single-sided lap welding, and the connection between the circumferential reinforcement and the vertical reinforcement can be achieved by binding.

[0051] The retaining wall formwork is assembled using small steel formwork panels with a steel plate thickness of no less than 3mm. During actual construction, it is fabricated in sections according to the cross-sectional size of the pile hole and the excavation progress. The panels are then assembled inside the hole and connected and fixed using pre-assembled steel pipe frames, top supports, bottom supports, and fasteners, achieving rapid construction. The concrete of the retaining wall body 21 should be tightly adhered to the surrounding rock. The support for the retaining wall concrete formwork can only be removed 12 hours after pouring. The next section of excavation should be carried out after the final setting of the previous section of retaining wall concrete. Similarly, the central part of the pile hole should be excavated first, followed by the perimeter of the retaining wall body 21. The pouring of the retaining wall concrete should be done in a continuous, integrated manner, avoiding any separation between sections.

[0052] The reinforcing bars of the retaining wall structure 20 should be continuously installed, and the retaining wall reinforcing bars should be connected to the retaining wall reinforcing bars already installed in the previous section. After the retaining wall reinforcing bar mesh is tied, the retaining wall formwork should be installed. C20 concrete should be used for the retaining wall. The retaining wall thickness should be 25cm at the interlocking joint, and 20cm for other sections.

[0053] When pouring the concrete for the main retaining wall 21, the first retaining wall 22, the second retaining wall 23, the third retaining wall, and the fourth retaining wall need to be constructed simultaneously and cast as a whole, ensuring symmetrical pouring and uniform compaction around the perimeter to prevent displacement of the formwork due to eccentric pressure. It should be noted that when excavating to the corresponding position, the support pier mold 24 should be installed in the designed position according to the angle of the support pier 12 shown in the design drawings, and then the retaining wall concrete should be poured, connecting the support pier mold 24 and the retaining wall concrete into a whole and fixing it securely. The retaining wall concrete should be compacted using an immersion vibrator to ensure its quality. For each section of the retaining wall structure 20 being constructed, a plumb bob should be used to center the pile and locate the axis control points. The pile axis should be determined on the excavation face to ensure that the pile structure dimensions are not less than the design requirements and the pile axis deviation is not greater than the specification value.

[0054] After the retaining wall structure 20 is poured, the anchor piles 10 can be poured. After the anchor piles 10 have reached a certain strength, the pier mold 24 can be recycled and reused when breaking the concrete of the retaining wall structure 20 and constructing the prestressed anchor cables.

[0055] Figure 5 This is a structural schematic diagram of the anchor pile provided in an embodiment of the present invention from one perspective. Figure 6 This is a structural schematic diagram of the anchor pile provided in this embodiment of the utility model from another perspective; Figure 7 yes Figure 5 A magnified schematic diagram of the local structure at point A.

[0056] See Figures 5 to 7 A third aspect of this utility model provides an anchor pile 10 manufactured from the aforementioned retaining wall structure 20. The anchor pile 10 includes a body 11, and protruding pads 12 are formed on the surface of the body 11. The number and position of the pads 12 can be adaptively set according to actual conditions. It is understood that the anchor pile 10 provided by this utility model has a stronger load-bearing capacity and better overall integrity because it has integrally formed pads 12. Compared with the structure in the prior art that requires secondary assembly, this setting avoids the delamination problem between the body 11 and the pads 12 of the anchor pile 10, which can solve the problem of assembly errors that are easy to occur when the pads 12 are assembled, and avoid the impact of this problem on subsequent construction.

[0057] Continue reading Figures 5 to 7In an optional embodiment of this utility model, the anchor pile 10 further includes a guide steel pipe 13, which passes through the body 11 and the pad 12. As mentioned above, when the guide steel pipe 13 is laid out, it needs to be aligned with the positioning hole 2421 on the bottom wall 242 of the pad mold 24. If necessary, the guide steel pipe 13 can be fixed to the bottom wall 242 of the pad mold 24 by riveting. It should be noted that during the installation of the pile reinforcement of the anchor pile 10, the guide steel pipe 13 needs to be firmly fixed to the pile reinforcement to prevent displacement during the concrete pouring process. The aforementioned limiting member 248 is used to guide and limit the pulling of the guide steel pipe 13, as described above.

[0058] Continue reading Figures 5 to 7 In an optional embodiment of this utility model, the anchor pile 10 further includes a positioning steel bar 14, which includes a first straight segment 15 and a second straight segment 16. The first straight segment 15 passes through the body 11 and the pier 12, and the second straight segment 16 is located at the end of the first straight segment 15 facing the pier 12 and is parallel to the bottom surface of the pier 12. It can be understood that by setting the positioning steel bar 14 and making the second straight segment 16 parallel to the bottom surface of the pier 12, the stress transfer area between the positioning steel bar 14 and the pier 12 can be increased, which can further improve the integrity of the pier 12 and the anchor pile 10 and its structural strength.

[0059] Continue reading 5 to 5 Figure 7 In an optional embodiment of this utility model, the anchor pile 10 further includes a head end component 17. The head end component 17 is located on the side of the pier 12 away from the main body 11. The head end component 17 includes a steel pad 18 and a head 19. The steel pad 18 is provided with a through hole for the anchor cable to pass through. Specifically, the steel pad 18 can be placed on the side of the pier 12 away from the main body 11 first, and the two can be fixed together with fasteners such as screws or bolts. After the anchor cable is pulled, the head 19 is then sealed on the side of the steel pad 18 away from the pier 12 using a mold. It can be understood that by setting the head end component 17, the guide steel pipe and the internal anchor cable and other rigid structures can be protected to prevent rainwater and air from corroding them.

[0060] It should be noted that the technical solutions in the various embodiments of this utility model can be combined with each other, but the basis for such combination is that they can be implemented by those skilled in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist, that is, it is not within the protection scope of this utility model.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
