TECHNICAL FIELD

[0001] The utility model relates to the hydraulic construction of river construction, especially the project investment fund is relatively nervous and cannot implement the cofferdam dry construction or the protection surrounding building cannot wide range excavate the foundation pit wharf combination. BACKGROUND

[0002] In recent years, the surrounding built building of project development is more and more dense, and the environmental protection problem is more and more serious, and the general river wharf construction is set cofferdam and is wide range slope excavation foundation pit, but the river cofferdam water construction is serious to water pollution, and the unit cost is also high, and wide range foundation pit excavation occupies a large amount of land, and sometimes because the existence of surrounding building cannot wide range excavate foundation pit. SUMMARY

[0003] In view of the deficiency in the prior art, the utility model embodiment provides a U pile solid shore wharf with soil retaining efficiency and ship berthing function, which not only has excellent soil retaining efficiency, but also integrates the ship berthing function, does not need to set the river cofferdam during construction, avoids the need for large-scale foundation pit excavation, and effectively saves the cost of setting the temporary cofferdam without actual benefit during project implementation. To achieve the above technical purpose, the utility model embodiment adopts the technical scheme that:

To achieve the above technical purpose, the utility model embodiment adopts the technical scheme that:

[0005] The U-shaped sheet pile is arranged at the water side in front of the wharf, and the pile top elevation is set to be higher than the normal water level; the side surfaces of adjacent U-shaped sheet piles are formed into dense wall bodies through male and female tenon buckling; the pile top of the U-shaped sheet pile is embedded into the bottom plate of the upper cast-in-place concrete structure;

[0006] The three-axis cement mixing piles are arranged behind the U-shaped sheet pile, and the three-axis cement mixing piles are connected in a row;

[0007] The PHC pipe piles are arranged behind the three-axis cement mixing piles, and the PHC pipe piles are arranged at intervals;

[0008] The upper cast-in-place concrete structure is cast-in-place and arranged on the top of the U-shaped sheet pile, the three-axis cement mixing pile and the PHC pipe pile;

[0009] The fender piece is arranged on the front side of the upper cast-in-place concrete structure.

[0010] Further, the pile top elevation of the U-shaped sheet pile is set to be 30cm higher than the normal water level.

[0011] Further, the pile top of the U-shaped sheet pile is embedded into the bottom plate of the upper cast-in-place concrete structure by 30cm.

[0012] Furthermore, the front-to-rear directions of adjacent U-shaped sheet piles are opposite.

[0013] Furthermore, the PHC piles are arranged in two rows at intervals.

[0014] Furthermore, the pile bottom of the U-shaped sheet pile is lower than the pile bottoms of the tri-axial cement mixing pile and the PHC pipe pile.

[0015] Furthermore, the fender is a rubber fender.

[0016] Compared with the prior art, the advantages of the present invention are:

[0018] 2) The top elevation of the U-shaped sheet pile is 30 cm higher than the normal water level, which ensures that the upper cast-in-place concrete structure can be cast in-situ without water, thereby improving construction safety.

[0019] 3) Triaxial cement mixing piles are arranged behind the U-shaped sheet piles to further strengthen the foundation, improve the bearing capacity and deformation resistance of the wharf, and prevent the soil behind the wharf from being hollowed out due to the disturbance of the wharf water body caused by the constant berthing and unberthing of ships, thereby avoiding the risk of structural instability. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a schematic diagram of the side structure of the U-pile shore-fixing wharf in an embodiment of the present utility model.

[0021] Figure 2 This is a schematic diagram of a U-pile shore-fixing wharf in an embodiment of the present utility model from a top view. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figure 1 As shown, the embodiment of the present invention proposes a U-pile shore-fixing wharf with both earth-retaining efficiency and berthing function, comprising a U-shaped sheet pile 1, a three-axis cement mixing pile 2, a PHC pipe pile 3, an upper cast-in-place concrete structure 4, and a fender 5;

[0024] The U-shaped sheet piles 1 are driven on the waterside of the front of the wharf, with the pile top elevation set above the normal water level; the sides of adjacent U-shaped sheet piles 1 are formed into a dense wall through mortise and tenon joints; the tops of the U-shaped sheet piles 1 are embedded in the bottom plate 401 of the upper cast-in-place concrete structure 4;

[0025] Three-axis cement mixing piles 2 are arranged behind the U-shaped sheet piles 1, and the three-axis cement mixing piles 2 are connected in a row;

[0026] PHC piles 3 are arranged behind the three-axis cement mixing piles 2, and the PHC piles 3 are arranged at intervals;

[0027] The upper cast-in-situ concrete structure 4 is cast-in-situ on top of the U-shaped sheet pile 1, the triaxial cement mixing pile 2 and the PHC pipe pile 3;

[0028] The fender 5 is arranged on the front side of the upper cast-in-situ concrete structure 4 .

[0029] The U-pile shore-fixed wharf proposed in this application has U-shaped sheet piles 1 driven at the water side of the wharf front, and the pile top elevation is usually set 30 cm above the normal water level, which effectively avoids the setting of a cofferdam near the river, and the upper cast-in-place concrete structure 4 can be cast in situ without water; the U-shaped sheet piles are used as retaining walls at the front of the wharf, and there is no need to set up a cofferdam near the river during construction, avoiding large-scale foundation pit excavation; the pile tops of the U-shaped sheet piles 1 are usually embedded in the bottom plate 401 of the upper cast-in-place concrete structure 4 by about 30 cm, and the sides of adjacent U-shaped sheet piles 1 are formed into a dense wall by mortise and tenon joints to ensure that the soil behind the wharf does not slide into the waterway; three-axis cement mixing piles 2 are arranged behind the U-shaped sheet piles 1, which effectively avoids the problem of loose interlocking of the U-shaped sheet piles during construction, thereby preventing the disturbance of the wharf water body caused by the long-term berthing and unberthing of ships, which leads to the hollowing out of the rear soil and ultimately causes structural instability.

[0030] Furthermore, the front-to-rear directions of adjacent U-shaped sheet piles 1 are opposite, which can improve the retaining bearing capacity of the retaining wall at the front of the wharf.

[0031] Furthermore, the PHC piles 3 are arranged in two rows at intervals, which can strengthen the foundation.

[0032] Furthermore, the pile bottom of the U-shaped sheet pile 1 is lower than the pile bottoms of the tri-axial cement mixing pile 2 and the PHC pipe pile 3, which can improve the soil retaining performance.

[0033] Specifically, the fender 5 is a rubber fender, which has both elasticity and durability.

[0034] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
