[0002] A retaining wall refers to a structure that supports roadbed fill or hillside soil and prevents the fill or soil from deforming and becoming unstable. It is widely used in highway engineering, water transport engineering and water conservancy engineering. Retaining walls often adopt solid structure, hollow box structure or sheet pile anchor structure. The specific construction process of retaining walls with solid structure or hollow box structure generally includes digging foundation pit, setting up retaining wall and backfilling soil and stone. The construction process of plate anchor structure can avoid excavation and backfilling soil behind the wall. However, in actual use, it is necessary to consider the surrounding environment of the location where the retaining wall is set. When setting up retaining walls in mountainous and open areas, the foundation pit can be excavated directly for construction. When there is a building above the foundation pit and the building cannot be demolished, the retaining wall cannot be constructed. Similarly, the sheet pile structure needs to be equipped with an anchor cable structure. When there is a building at the foundation pit that the anchor cable cannot pass through, the construction cannot be completed.
[0003] It can be seen from the above that the retaining wall in the prior art has the problem of poor applicability. Utility Model Content

[0026] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0027] In order to solve the problem of poor applicability of retaining walls in the prior art, the utility model provides a fork pile type retaining wall structure.
[0028] like Figures 1 to 4 As shown, the fork pile retaining wall structure includes a retaining member 10, a supporting member 40 and a reinforcing member 50. The retaining member 10 is used to block the earth and stone material 20. The supporting member 40 is located on the side of the retaining member 10 away from the earth and stone material 20. The supporting member 40 is inclined relative to the retaining member 10 and arranged in the waterway 30. The top of the supporting member 40 abuts against the top of the retaining member 10 to prevent the retaining member 10 from moving. The distance between the supporting member 40 and the retaining member 10 gradually increases in the direction away from the top of the retaining member 10. The reinforcing member 50 is located between the retaining member 10 and the supporting member 40 and away from the top of the supporting member 40. One end of the reinforcing member 50 is connected to the retaining member 10, and the other end is connected to the supporting member 40, and is used to connect the retaining member 10 and the supporting member 40.
[0029] The retaining member 10 is used to block the earth and rock materials 20 on one side of the waterway 30 to prevent the earth and rock materials 20 from falling into the waterway 30. The support member 40 is tiltedly arranged in the waterway 30, with the top of the support member 40 close to the retaining member 10 and the bottom of the support member 40 away from the retaining member 10. The reinforcement member 50 connects the support member 40 and the retaining member 10 to form a stable triangular structure. The arrangement of the support member 40 in the waterway 30 is simple to construct, does not require excavation and backfilling of the soil behind the wall, and does not require the arrangement of an anchor cable structure. Even if an irremovable building 80 is arranged behind the retaining member 10, construction can still be carried out, thereby meeting the construction requirements in a variety of environments and improving the applicability of the retaining wall.
[0030] In this embodiment, the retaining element 10 is a pile foundation, and there are multiple pile foundations. The multiple pile foundations are arranged in sequence along a first direction to form a pile foundation row for isolating the waterway 30 and the earth and rock material 20. The first direction is the length direction of the waterway 30.
[0031] Specifically, the retaining members 10 are arranged in sequence along the length direction of the channel 30. The pile foundation rows formed can prevent earth and stone materials 20 from falling into the channel 30 and affecting the navigation safety of ships in the channel 30. At the same time, the pile foundation rows can also prevent the river water in the channel 30 from eroding the river bank and reducing soil and water loss.
[0032] Optionally, a filling material is filled between the pile foundation rows, which can ensure the sealing of the pile foundation row while ensuring the connection reliability between two adjacent pile foundations in the pile foundation row.
[0033] like Figure 1 to Figure 2 As shown, the fork pile retaining wall structure further includes a waist beam 60, which is arranged on a side of the retaining element 10 away from the soil and rock material 20, and the waist beam 60 is arranged along the first direction.
[0034] Specifically, the length of the waist beam 60 is adapted to the width of the pile foundation row formed by the plurality of retaining elements 10, so as to achieve the effect of strengthening the fork-pile retaining wall structure and prevent the middle of the retaining element 10 from protruding toward the channel 30, resulting in a "big belly", which in turn causes the fork-pile retaining wall structure to fail. Optionally, there are a plurality of waist beams 60, and the plurality of waist beams 60 are spaced apart on the retaining element 10 along the first direction.
[0035] like Figure 1 to Figure 2 As shown, the fork-pile retaining wall structure further includes a cap beam 70 , which is disposed on the top of the pile foundation. The cap beam 70 connects the pile foundation and the support member 40 , and the cap beam 70 and the waist beam 60 are disposed at intervals.
[0036] Specifically, the support member 40 provides a supporting reaction force for the retaining member 10, and the cap beam 70 connects the top of the retaining member 10 and the top of the support member 40, so as to realize the transfer of load, so that the support member 40 and the retaining member 10 are subjected to force in coordination. Optionally, the length of the portion of the retaining member 10 and the support member 40 extending below the bottom surface of the channel is greater than or equal to the length of the portion located above the bottom surface of the channel, so as to improve the retaining effect and structural strength of the fork pile retaining wall structure.
[0037] In this embodiment, there are multiple support members 40 and reinforcement members 50, and the multiple support members 40 are arranged at intervals along the first direction. The multiple support members 40 are all connected to the cap beam 70, and the multiple reinforcement members 50 are arranged at intervals along the first direction on the waist beam 60. The multiple reinforcement members 50 and the multiple support members 40 are arranged in a one-to-one correspondence.
[0038] Specifically, the support members 40 are arranged at intervals in the waterway 30, which can reduce the erosion of the support members 40 by the river water while ensuring the support of the retaining member 10, thereby improving the service life of the fork pile type retaining wall structure. The reinforcement members 50 are arranged on the waist beam 60 in a horizontal direction or in a horizontally upward manner. By arranging the reinforcement members 50 and the support members 40 in a one-to-one correspondence, the fork pile type retaining wall structure has a plurality of stable triangular structures.
[0039] In another embodiment of the present application not shown in the figure, there are two waist beams 60, the two waist beams 60 are arranged on the retaining element 10 at intervals, a plurality of reinforcing members 50 are arranged between the two waist beams 60, and the plurality of reinforcing members 50 are arranged on the retaining element 10 at intervals along the first direction. Optionally, there are multiple waist beams 60, and a plurality of reinforcing members 50 are arranged between any two adjacent waist beams 60 at intervals along the first direction.
[0040] like Figure 3 to Figure 4As shown, in another embodiment of the present application, a connection structure 11 is provided on the soil retaining member 10, and the reinforcement member 50 and the connection structure 11 are spaced apart along a second direction, and the second direction is perpendicular to the first direction.
[0041] Specifically, the connection structure 11 is arranged on the top of the retaining member 10, and the retaining member 10 is in an inverted L-shape as a whole. The support member 40 abuts against the connection structure 11, and the reinforcement member 50 is parallel to the connection structure 11. The connection structure 11 is a steel structure or a reinforced concrete structure, and has certain performances of anti-punching, anti-bending and anti-shearing, and can withstand the force and torque generated by the support member 40 and the retaining member 10. In this embodiment, the connection structure 11 and the retaining member 10 are integrally formed. Optionally, the connection structure 11 and the retaining member 10 are detachably connected by bolts.
[0042] In this embodiment, there are multiple reinforcement members 50 and support members 40, and the multiple reinforcement members 50 are arranged one by one with the multiple support members 40. The multiple support members 40 are all arranged in the channel 30 at intervals along the first direction, and the connecting structure 11 is detachably connected to the multiple support members 40.
[0043] Specifically, the length direction of the connecting structure 11 is consistent with the width direction of the retaining member 10, and the supporting effect is improved by the abutment of multiple support members 40. Since the support members 40 and the connecting structure 11 are detachably connected, when a single support member 40 needs to be replaced, only the single support member 40 can be operated, thereby avoiding the replacement of the entire fork pile retaining wall structure and reducing maintenance costs.
[0044] In another embodiment of the present application which is not shown in the figure, the support member 40 and the connection structure 11 are integrally formed, and the connection structure 11 is detachably connected to the soil retaining member 10 .
[0045] In this embodiment, a connecting groove is provided on the connecting structure 11 , and the connecting groove is adapted to the supporting member 40 . There are a plurality of connecting grooves, and the plurality of connecting grooves are provided in a one-to-one correspondence with the plurality of supporting members 40 .
[0046] Specifically, the connection groove is adapted to the shape of the support member 40, has a certain depth, and is obliquely opened on the connection structure 11 to adapt to the support member 40 being obliquely set and abutting against the connection structure 11. Optionally, the connection structure 11 is inclined upward relative to the horizontal plane, and the connection groove is vertically opened on the connection structure 11, which can be selected according to actual needs.
[0047] In this embodiment, the soil retaining member 10 is vertically arranged, and the angle formed between the supporting member 40 and the soil retaining member 10 is 7° to 15°.
[0048] Specifically, when the common support member 40 is tilted, the angle between the support member 40 and the vertical plane is in the range of 7° to 15°, wherein the force effect is better between 12° and 15°, which can provide a better support effect and have a longer service life. Due to the limitations of geological conditions and construction equipment conditions, the angles are generally 4:1, 5:1 and 8:1, that is, the angle values are 14°2′10″, 11°18′36″ and 7°7′30″. In this embodiment, the angle between the support member 40 and the horizontal plane is 5:1, that is, 11°18′36″.
[0049] In this embodiment, the retaining member 10 and the supporting member 40 are prefabricated steel pipe piles or reinforced concrete pipe piles.
[0050] Specifically, the retaining member 10 and the supporting member 40 are prefabricated structures. Before construction, the prefabricated structures are transported to the construction site and then assembled, which can speed up the construction and make the structure simpler. Optionally, during prefabrication, multiple prefabricated structures are prefabricated to prevent the prefabricated structures from being damaged during transportation.
