Description

Technical Field

[0001] The invention relates to an inclined pile group side span structure for complementary fishing and light and a construction method. Background Art

[0002] In order to increase the utilization efficiency of fish ponds and other areas, people have developed a land utilization model of fish-photovoltaic complementarity. With less impact on fishery farming, photovoltaic panels are installed, solar energy utilization is developed, and the comprehensive benefits of fish ponds are improved. In order to adapt to the special conditions of fish ponds, flexible brackets are usually used to install photovoltaic panels.

[0003] The photovoltaic flexible support transfers the load to the side span structure through the pre-stressed cable structure. Due to the large prestress in the cable, the side span structure needs to bear both vertical and horizontal loads at the same time, and the load is a dynamic load. In addition, the underground soil of the fish pond is relatively soft, which puts higher requirements on the long-term stability of the side span structure.

[0004] The side span structure generally adopts vertical pile foundation or vertical single pile + anchor (anchor cable) scheme. When the vertical pile foundation adopts a single pile, the vertical bearing capacity of the single pile can generally meet the requirements, but the horizontal displacement of the single pile is large, and it is difficult to meet the deformation requirements of the relevant specifications. A pile with a larger diameter is required to meet the deformation requirements of the relevant specifications in the horizontal direction, resulting in great construction difficulty and high cost. When the vertical pile foundation adopts a group of piles, a large number of foundation piles are required, the engineering volume is large, and the cost is high.

[0005] The vertical single pile + anchor (anchor cable) solution uses pile foundation to provide vertical bearing capacity and inclined anchors to provide horizontal bearing capacity. This can give full play to the respective advantages of piles and anchors, but the piles and anchors are subjected to force separately, the structure has weak deformation control ability, poor integrity, the anchor structure is long, the construction quality is difficult to control, and a large additional space is required, resulting in low land utilization rate.

[0006] In some schemes, inclined piles are used as pile foundations. Although this can improve the ability of pile foundations to resist horizontal loads to a certain extent, it is difficult to construct them technically. When inclined piles are cast-in-place piles such as bored piles, due to the abundant groundwater in the construction area, it is difficult to drill the pile holes for bored piles, which can easily cause pile hole collapse and buried drills. In addition, the drill rod is prone to deflection during construction, causing bending in the pile hole, affecting the sinking of the steel cage. The pouring quality of underwater concrete is difficult to control, and the construction requirements are high. When prefabricated piles are used as inclined piles, the pile driver needs to be inclined for construction, and the positioning accuracy of the pile body on the ground is poor, resulting in low construction accuracy and easy to cause incoordination between adjacent foundation piles.

[0007] In view of the above reasons, how to complete the side span structure of photovoltaic flexible bracket at low cost and high quality is still a problem that needs to be solved. Summary of the invention

[0008] In order to reduce the construction cost of the side span structure of the existing photovoltaic flexible support and improve its construction accuracy, the present application first proposes an inclined group pile side span structure for fish-photovoltaic complementation, which includes a plurality of combined pile groups arranged at intervals along the second axis direction, and each combined pile group includes two combined pile structures arranged at intervals along the first axis direction;

[0009] At least one composite pile structure includes a cap foundation and two inclined piles connected to the cap foundation, the upper ends of the inclined piles extend upward from the ground, and of the two inclined piles in the same composite pile structure, either inclined pile is inclined toward the other inclined pile, and the cap foundation is connected to the middle part of the inclined pile in the axial direction, so that the composite pile structure is A-shaped;

[0010] An anchor block is arranged on the top of two inclined piles in the same composite pile structure, and the anchor block connects the top ends of the two inclined piles in the same composite pile structure together. The cable extends along the first axis direction, and the two ends of the cable are anchored on the anchor block respectively; the connecting beam connects the composite pile structures located on the same side in the first axis direction, and the first axis direction and the second axis direction both extend in the horizontal direction and are perpendicular to each other.

[0011] Preferably, the center lines of the four inclined piles of the same combined pile structure are located in the same vertical plane extending along the first axis direction.

[0012] In the present application, the cap foundation, the inclined piles, the connecting beams and the cables together form a spatial truss structure, which has large overall rigidity, high stability and high anti-deformation ability. The relatively inclined inclined piles can provide a large pile side friction resistance and have a high horizontal bearing capacity, which can effectively reduce the horizontal displacement of the pile top and the vertical displacement of the pile bottom, and thus effectively reduce the uplift of the soil around the pile.

[0013] Inclined piles can provide horizontal bearing capacity by bearing pressure, giving full play to the axial bearing capacity of the piles to reduce the shear force and bending moment caused by lateral loads, saving a lot of building materials and reducing construction costs. The cap foundation can also serve as a construction platform for inclined piles, and special guide holes can be set on the cap foundation to reduce the difficulty of inclined pile construction.

[0014] As a post-cast part, the anchor block can correct the construction deviation of the inclined pile, and the construction quality is easy to control, which can effectively improve the construction quality.

[0015] Furthermore, in order to facilitate the sinking of the inclined pile, a guide hole is reserved on the cap foundation, and the inclined pile can be sunk into the ground through the guide hole. After the inclined pile is sunk, high early strength grouting material is poured into the guide hole to connect the inclined pile with the cap foundation. At present, when sinking the inclined pile, it is usually necessary to set up a special guide frame. The design in the present application can make the cap foundation serve as a guide frame and eliminate the guide frame specially set in the prior art.

[0016] Furthermore, in order to improve the connection strength between the inclined pile and the pedestal foundation, a lower reinforcement hole is provided on the inclined pile, and the lower connecting reinforcement passes through the lower reinforcement hole and is connected to the steel cage in the pedestal foundation; the lower connecting reinforcement is poured in the high early strength grouting material.

[0017] Further, the guide cylinder is fixedly installed in the guide hole, and the inclined pile can sink into the ground through the guide cylinder. After the inclined pile completes sinking, the guide cylinder is removed, and then high early strength grouting material is poured into the guide hole. The outer diameter of the guide cylinder is smaller than the inner diameter of the guide hole. Preferably, the inner diameter of the guide hole is 100-500mm larger than the outer diameter of the inclined pile. In order to improve the guiding effect of the guide cylinder, at least one end of the guide cylinder extends out of the guide hole to extend the length of the guide cylinder. The use of a larger guide hole is conducive to accurately adjusting the inclination and sinking position of the inclined pile. Due to the construction defects of the concrete construction itself, its construction accuracy is low, and the guide cylinder is used to correct the defect. In addition, after the guide hole is enlarged, it is more conducive to pouring high early strength grouting material into the guide hole, so that the high early strength grouting material can fill the gap between the guide hole and the inclined pile.

[0018] Furthermore, an upper reinforcement hole is provided at the top of the inclined pile, and the upper connecting reinforcement passes through the upper reinforcement hole and is connected to the steel cage in the anchor block. The tops of the two inclined piles in the same composite pile structure are completely connected together by the anchor block. The upper connecting reinforcement can make the two inclined piles more firmly connected as a whole, thereby ensuring the connection strength between the two inclined piles. In order to further improve the connection strength between the inclined pile and the anchor block, when the inclined pile adopts a hollow pile, a core-cast steel cage is inserted in the inner cavity of the inclined pile. The core-cast steel cage extends upward from the inner cavity of the inclined pile and is connected to the steel cage in the anchor block. When the anchor block is poured, concrete can enter the inner cavity of the inclined pile to wrap the core-cast steel cage and the upper connecting reinforcement located in the inner cavity of the inclined pile.

[0019] Specifically, the cable is anchored on the connecting beam, and at least one cable is arranged on both sides of the second axis direction of a combined pile structure. Alternatively, a cable hole extending along the first axis direction is reserved on the anchor block, and the cable is locked on the anchor block after passing through the cable hole. In specific construction, different cable arrangements can be adopted according to different requirements.

[0020] Furthermore, the two combined pile structures in each combined pile group are respectively called the first combined pile structure and the second combined pile structure. In the first axis direction, in each combined pile group, the second combined pile structure is located on the same side of the first combined pile structure; at least part of the first combined pile structure is arranged in a row along the second axis direction, or at least part of the second combined pile structure is arranged in a row along the second axis direction. This design can facilitate the installation of the connecting beam and improve space utilization.

[0021] Preferably, the capping foundations of at least two first combined pile structures are connected as a whole, or the capping foundations of two second combined pile structures are connected as a whole.

[0022] Secondly, in order to facilitate the realization of the above-mentioned inclined pile group side span structure, the present application also proposes a construction method of the inclined pile group side span structure described in any one of the above items, which comprises the following steps:

[0023] (1) constructing a cap foundation in a set area, reserving a guide hole on the cap foundation, inserting a guide cylinder into the guide hole, and detachably fixing the guide cylinder on the cap foundation;

[0024] (2) Sinking the inclined pile into the ground through the guide tube;

[0025] (3) Then, the guide tube is removed, the lower connecting reinforcement is passed through the lower reinforcement hole on the inclined pile and connected to the steel cage in the cap foundation, high early strength grouting material is poured into the guide hole, and the inclined pile is connected to the cap foundation;

[0026] (4) Install the steel cage of the anchor block on the top of the inclined pile, pass the upper connecting bar through the upper through-bar hole at the top of the inclined pile and connect it to the steel cage of the anchor block, and pour concrete to form the anchor block;

[0027] (5) Erect connecting beams and install cables.

[0028] In this construction method, the guide cylinder on the foundation is used to reduce the construction difficulty of the inclined pile. After the inclined pile is sunk, the anchor block is poured, and the post-cast anchor block is used to correct the construction deviation of the inclined pile to ensure the construction quality. Since the guide cylinder is set, the inclined pile can be accurately positioned. When the inclined pile is sunk without a guide, the inclined pile is easy to deviate from the original set position. When the inclined pile is sunk only by relying on the guide hole, due to the defects existing in the concrete pouring itself, the guide hole often has a certain deviation. The use of the guide cylinder can not only correct the deviation of the guide hole, but also set a longer guide cylinder to improve the guiding effect of the guide cylinder, which is more conducive to the accurate positioning of the inclined pile.

[0029] Furthermore, in step (2), when sinking the inclined pile, a support frame for the inclined pile is not provided, and the inclined pile is only supported on the guide cylinder and the pile clamping device of the pile driver. When sinking the inclined pile, first insert the lower end of the inclined pile into the guide cylinder, and clamp the pile clamping device of the pile driver itself at the upper end of the inclined pile, and the positioning of the inclined pile can be completed. This design can reduce construction costs while ensuring the accurate sinking of the inclined pile. At present, when sinking the inclined pile, it is usually necessary to set up a special guide frame. Before sinking the pile, it is necessary to arrange the pile body on the guide frame first, and use the guide frame to position the inclined pile. After completing the positioning of the inclined pile, the inclined pile is sunk. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following is an explanation of the inclined pile group side span structure of the fishing-solar hybrid system. Figure 1 The first arrow X in the accompanying drawings indicates the direction of the first axis, and the second arrow Y indicates the direction of the second axis. The first axis and the second axis both extend in the horizontal direction and are perpendicular to each other.

[0041] The inclined pile group side span structure specifically comprises a plurality of combined pile groups 200 spaced apart along the second axis direction. Figure 1 Eight combined pile groups are shown as an example. Figure 1 In FIG. 2 , a double-dotted line is used to show the range of a combined pile group 200. It can be understood that, according to different requirements, each inclined pile group side span structure can also include only two combined pile groups, or include 5, 10, 20 or even more combined pile groups.

[0042] Each combined pile group includes two combined pile structures spaced apart along the first axis. For ease of description, the two combined pile structures in each combined pile group are respectively referred to as a first combined pile structure 201 and a second combined pile structure 202. In the first axis direction, in each combined pile group, the second combined pile structure 202 is located on the same side of the first combined pile structure 201. Figure 1 In the embodiment, the second combined pile structures 202 are all located on the right side of the first combined pile structures 201. In the embodiment, the first combined pile structures 201 are arranged in a row along the second axis direction, and the second combined pile structures 202 are arranged in a row along the second axis direction.

[0043] The first connecting beam 311 connects the first composite pile structures 201 together, and the second connecting beam 312 connects the second composite pile structures 202 together. That is, the connecting beam connects the composite pile structures located on the same side in the first axis direction.

[0044] See also Figure 2 In this embodiment, each composite pile structure includes a cap foundation 21 and two inclined piles 22 connected to the cap foundation. The upper end of the inclined pile extends upward from the ground. In the two inclined piles in the same composite pile structure, any inclined pile is inclined toward the other inclined pile. The cap foundation 21 is connected to the middle part of the inclined pile in the axial direction, so that the composite pile structure is A-shaped. An anchor block 23 is provided on the top of the two inclined piles in the same composite pile structure. The anchor block connects the tops of the two inclined piles in the same composite pile structure together. The inclined piles specifically adopt PHC pipe piles. In other embodiments, the inclined piles can also adopt square piles or solid piles. There are no special requirements for the specific selection of the inclined piles. However, since this application is used in high humidity areas such as fish ponds, the inclined piles are required to have strong corrosion resistance. When steel piles are used as inclined piles, anti-corrosion treatment is required. However, it is generally not recommended to use steel piles. Concrete piles are preferably used. Figure 2 In the figure, reference numeral 100 indicates the ground.

[0045] In this embodiment, in order to improve the integrity of the inclined pile group side span structure, the cap foundations in the ten first combined pile structures are connected to each other and form a whole, and the cap foundations in the ten second combined pile structures are connected to each other and form a whole. Figure 1In the figure, dotted lines are used to represent the cap foundations connected as a whole. It is understood that in other embodiments, an independent cap foundation may be provided for each composite pile structure, or two, three or more adjacent cap foundations may be connected as a whole. That is, the cap foundations of at least two first composite pile structures are connected as a whole, or the cap foundations of two second composite pile structures are connected as a whole.

[0046] In this embodiment, two cables 32 are provided corresponding to each composite pile structure. The two cables 32 are respectively located on both sides of the second axis direction of the corresponding composite pile structure. The cables 32 extend in the first axis direction, and the two ends of the cables are respectively fixed on the first connecting beam 311 and the second connecting beam 312 through anchors, so that the two ends of the cables are respectively anchored on the anchor block through the first connecting beam 311 and the second connecting beam 312. That is, in this embodiment, a cable is provided on both sides of the second axis direction of each composite pile structure. It can be understood that, according to different needs, a cable can also be provided on both sides of the second axis direction of only some composite pile structures, and a cable can be provided on one side of some composite pile structures. It can be understood that the cable can also be directly anchored on the anchor block. In this embodiment, the cable adopts a steel strand, and the steel strand is anchored by a clip-type anchor 33. It can be understood that in other embodiments, fine-rolled threaded steel can also be used as the cable. When fine-rolled threaded steel is used as the cable, the fine-rolled threaded steel can be anchored by a fine-rolled nut.

[0047] In this embodiment, the first connecting beam 311 and the second connecting beam 312 are both fixed on the anchor block 23. To facilitate the installation of the first connecting beam and the second connecting beam, a connecting bolt 236 is pre-embedded on the anchor block, and the first connecting beam and the second connecting beam are fixed to the anchor block 23 via the connecting bolt 236. The first connecting beam and the second connecting beam are both composed of two side-by-side H-shaped steels, and the cable passes through the gap between the two side-by-side H-shaped steels and is anchored via the clip-type anchor 33.

[0048] When the cable is directly anchored on the anchor block, it is necessary to reserve a cable hole extending along the first axial direction on the anchor block. After the cable passes through the cable hole, it is locked on the anchor block. After the installation and tensioning of the cable are completed, epoxy resin glue or high early strength grouting material is injected into the cable hole to improve the connection strength between the cable and the anchor block. However, after the epoxy resin glue or high early strength grouting material is injected into the cable hole, during the subsequent use, when the cable undergoes plastic deformation and stretches, it can no longer be tensioned for the second time to tension the cable. Therefore, it is necessary to decide whether to inject epoxy resin glue or high early strength grouting material into the cable hole according to specific requirements.

[0049] In order to enable each inclined pile to be subjected to force in the same direction and to prevent some inclined piles from being subjected to larger force components in other directions and causing torsion, in this embodiment, the center lines of the four inclined piles of the same combined pile structure are located in the same vertical plane extending along the first axis direction. This design enables each inclined pile to mainly bear the force component in the direction of the first axis and the force component in the vertical direction.

[0050] See also Figure 4 In order to facilitate the sinking of the inclined pile 22, a guide hole 212 is provided in the cap foundation 21 corresponding to each inclined pile 22. The inner diameter of the guide hole is 100-500 mm larger than the outer diameter of the inclined pile. In this embodiment, the inner diameter of the guide hole is 200 mm larger than the outer diameter of the inclined pile, so as to facilitate the supplementation of the connecting reinforcement and the pouring of the high early strength grouting material 214. At the same time, in order to facilitate the fine adjustment of the position of the inclined pile, a guide cylinder 25 is inserted in the guide hole 212. Please refer to Figure 5 In order to facilitate the fixing of the guide cylinder 25, a positioning plate 27 is welded on the outer wall of the guide cylinder, and an internal threaded tube 271 is pre-buried on the foundation of the platform. The locking bolt 272 passes through the positioning plate 27 and is screwed into the internal threaded tube 271 to fix the positioning plate 27 on the upper surface of the foundation of the platform. It can be understood that in another embodiment, the positioning plate can also be fixed to the foundation of the platform by using expansion bolts. The guide cylinder is specifically made of a steel pipe.

[0051] The tilted pile is sunk into the ground through the guide cylinder. The position and tilt angle of the tilted pile can be fine-tuned by using the guide cylinder to correct the deviation of the foundation or the guide hole due to construction errors. After the tilted pile is sunk, the locking bolt 272 is removed and the guide cylinder is taken out from the top of the tilted pile. When the guide cylinder cannot be taken out due to the obstruction of another tilted pile, the guide cylinder can be cut. In this embodiment, the upper end of the guide cylinder extends upward beyond the upper surface of the foundation, so that the guide cylinder extends upward out of the guide hole. It can be understood that in other embodiments, the guide cylinder can also extend downward out of the guide hole, or the upper and lower ends of the guide cylinder can extend upward and downward out of the guide hole respectively.

[0052] In order to avoid large friction between the guide tube and the inclined pile, which affects the sinking efficiency of the inclined pile, and to reduce excessive vibration of the cap foundation during piling, the inner diameter of the guide tube is 1-10 mm larger than the outer diameter of the inclined pile. In this embodiment, the inner diameter of the guide tube is 4 mm larger than the outer diameter of the inclined pile.

[0053] Please also see Figure 4 and Figure 5After the guide tube is removed, the lower connecting bar 213 is passed through the lower through-bar hole 221 on the inclined pile and connected to the lower steel cage 211 in the cap foundation 21, and then the high early strength grouting material 214 is poured in the guide hole to fix the inclined pile to the cap foundation. The lower connecting bar is poured in the high early strength grouting material, and the high early strength grouting material can enter the inner cavity of the inclined pile through the lower through-bar hole to wrap the lower connecting bar 213 in the inner cavity of the inclined pile. The high early strength grouting material also has the names of super early strength grouting material, high strength grouting material, high strength cement-based grouting material, etc.

[0054] It can be understood that, according to different requirements, in another embodiment, the lower connecting ribs and the corresponding lower rib holes can be eliminated, and after the guide cylinder is removed, the grouting material can be directly poured into the guide hole. Of course, in another embodiment, the guide cylinder can also be eliminated. In this case, the guide hole needs to be accurately reserved, and a steel cylinder can be embedded in the guide hole. After the inclined pile is sunk, high early strength grouting material is poured into the gap between the guide hole and the inclined pile. According to different needs, a boss can also be poured on the upper side of the cap foundation, and the cap foundation and the inclined pile are connected together by the boss. However, in these connection methods, cracks will appear between the cap foundation and the inclined pile after a long period of operation, and their service life and connection strength are weaker than the method of using the lower connecting ribs.

[0055] Please also see Figure 3 and Figure 5 In order to improve the connection strength between the anchor block 23 and the inclined pile 22, an upper rib hole 222 is provided at the top of the inclined pile 22, and the upper connecting rib 233 passes through the upper rib hole 22 and is connected to the upper steel cage 231 in the anchor block. In order to further improve the connection strength between the anchor block 23 and the inclined pile 22, a core steel cage 232 is inserted into the inner cavity of the inclined pile, and the core steel cage extends upward from the inner cavity of the inclined pile and is connected to the upper steel cage 231. During the pouring process of the anchor block, concrete can enter the inner cavity of the inclined pile and wrap the core steel cage 232 and the upper connecting rib located in the inner cavity of the inclined pile.

[0056] The following is an explanation of the construction method of the inclined pile group side span structure, which includes the following steps:

[0057] (1) Please refer to Figure 6 , construct a cap foundation 21 in a set area, reserve a guide hole 212 on the cap foundation 21 , insert the guide cylinder 25 into the guide hole 212 , and detachably fix the guide cylinder 25 on the cap foundation 21 .

[0058] (2) Please refer to Figure 7 , the inclined pile 22 is sunk into the ground through the guide cylinder 25.

[0059] (3) Please refer to Figure 8 Then, the guide cylinder 25 is removed, the lower connecting reinforcement is passed through the lower reinforcement hole on the inclined pile and connected to the lower reinforcement cage in the cap foundation, high early strength grouting material is poured into the guide hole, and the inclined pile is connected to the cap foundation.

[0060] (4) Please refer to Fig. 9 , install the upper steel cage 231 of the anchor block 23 on the top of the inclined pile 22, pass the upper connecting bar through the upper reinforcement hole on the top of the inclined pile and connect it to the upper steel cage of the anchor block, pour concrete to form the anchor block 23.

[0061] (5) Please refer to Fig.10 , erect the first connecting beam 311 and the second connecting beam 312, and install the cable 32.

[0062] When sinking the inclined pile, no other guiding device of the inclined pile is required. The inclined pile is positioned only by relying on the pile driver and the guide tube, so that the inclined pile can be accurately positioned and sunk to the set position, which can effectively reduce the construction cost.
