Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a prefabricated concrete pipe pile retaining device. Background Art

[0002] Concrete pipe piles are widely used in our current construction, bridge erection and other fields. The protective sealing of the ends of concrete pipe piles is particularly important.

[0003] After searching, a Chinese patent with announcement number CN216108473U discloses a prestressed concrete pipe pile end sealing device, including a pile head end plate, a steel pad, and an annular sealing pad; the pile head end plate is placed on the end of the prestressed concrete pipe pile; the steel pad is placed on the pile head end plate; an annular inner edge seal and an annular outer edge seal are provided on the steel pad, and the distance between the annular inner edge seal and the annular outer edge seal is slightly greater than the wall thickness of the prestressed pipe pile body; the annular sealing pad is placed between the pile head end plate and the steel pad; an annular inner sealing ring and an annular outer sealing ring are provided on the annular sealing pad, the annular inner sealing ring is placed between the inner wall of the prestressed concrete pipe pile and the annular inner edge seal, and the annular outer sealing ring is placed between the outer wall of the prestressed concrete pipe pile and the annular outer edge seal.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] During the construction process of existing precast concrete pipe piles, due to the poor sealing of their ends, underground earth and mud will enter the interior of the precast concrete pipe piles during construction, resulting in the need to clean the interior when the precast concrete pipe piles are poured in the later stage, affecting the construction efficiency, so there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a precast concrete pipe pile retaining device, which can effectively seal and protect the end of the precast concrete pipe pile, prevent underground earth and mud from entering the pipe pile through the middle hole of the precast concrete pipe pile, avoid the need to clean the earth in the pipe pile before the later precast concrete pipe pile core pouring process, and improve construction efficiency.

[0007] The technical solution for achieving the purpose of the utility model is: a precast concrete pipe pile earth retaining device, comprising a precast concrete pipe pile, a steel ring piece is fixedly installed on the top of the precast concrete pipe pile, a threaded hole is reserved on the steel ring piece, a rubber gasket is fixedly installed on the top of the steel ring piece, and an earth retaining sleeve is arranged on the top of the rubber gasket.

[0008] In some embodiments, the retaining sleeve is threadedly connected to the steel ring piece and the precast concrete pipe pile by a plurality of high-strength bolts.

[0009] In some embodiments, a pair of vertically staggered connecting rods are disposed inside the soil retaining sleeve, and a plurality of annular grooves are formed on the pair of connecting rods.

[0010] In some embodiments, the end of each high-strength bolt is sleeved with a bolt protection sleeve, and the end of each bolt protection sleeve is commonly fixedly mounted with a connecting ring.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First, the utility model utilizes the earth retaining sleeve to seal the end of the precast concrete pipe pile, and utilizes multiple bolts to make the connection between the earth retaining sleeve and the precast concrete pipe pile more firmly. At the same time, a rubber gasket is provided between the two to further improve the sealing performance of the device. In addition, a pair of connecting rods are provided inside the earth retaining sleeve, and an annular groove is provided on the connecting rod, which is convenient for the lifting device to lift the precast concrete pipe pile, and also convenient for removing the earth retaining sleeve for recycling.

[0013] Secondly, the utility model adds a bolt protection cover on the top of the bolt, and the bolt protection cover can be easily taken and placed through the connecting ring. The construction site capability is strong, the construction can be completed with simple operation, and the construction is convenient.

[0014] The invention solves the problem that during the construction of the existing precast concrete pipe piles, due to the poor sealing of the ends thereof, underground earth and mud will enter the interior of the precast concrete pipe piles during construction, resulting in the need to clean the interior during the later core pouring of the precast concrete pipe piles, thus affecting the construction efficiency.
