Embodiment 1

[0047] A specific embodiment of the present invention discloses a prestressed concrete corrugated sheet pile, such as Figure 1 to Figure 2 As shown, it includes a corrugated pile body 101, one side along the length direction of the corrugated pile body 101 is provided with a tenon 102, and the other side is provided with a first groove 103, and the tenon 102 can be inserted into the first recess without gap. In the groove 103 , the cross sections of the tenon 102 and the first groove 103 are both semicircular, and the tenon 102 can rotate in the first groove 103 . The concave surface of the first groove 103 is provided with a second groove 104 along the length direction of the corrugated pile body 101, and the second groove 104 can be filled with water-expandable waterproof glue; the first groove 103 has a second groove 104 A radius is greater than the second radius that the second groove 104 has, such as image 3 As shown, preferably, the second radius is 1 / 20˜1 / 8 of the fi...

Embodiment 2

[0053] This embodiment discloses the preparation method of the prestressed concrete corrugated sheet pile in the first embodiment. The preparation method uses the mold for producing the prestressed concrete corrugated sheet pile to prepare, and includes the following steps: assembling the mold to form a filled steel cage skeleton, prestressing Reinforcement and concrete mold cavity; Install corrugated sheet pile steel cage skeleton and prestressed steel bar in the mold cavity; Utilize tensioning equipment to stretch the prestressed steel bar; Concrete is poured in the mold cavity with prestressed steel bar and Vibration forming; overall maintenance of the cast concrete mold; after the specified time of maintenance, prestressed steel bars are stretched and demoulded to complete the production of prestressed concrete corrugated sheet piles.

[0054] The specific preparation process of the prestressed concrete corrugated sheet pile in this embodiment is as follows:

Abstract

The invention relates to a prestressed concrete corrugated sheet pile and a preparation method thereof, and belongs to the technical field of construction engineering. The prestressed concrete corrugated sheet pile solves the problems that an existing corrugated sheet pile is poor in soil blocking and water retaining effect and prone to damage at a corrugated sheet pile joint in the transportationprocess. The prestressed concrete corrugated sheet pile comprises a corrugated pile body, wherein a tenon is arranged on one side in the length direction of the corrugated pile body in a penetratingmode, and a first groove is formed in the other side of the corrugated pile body in a penetrating mode; the cross section of the tenon and the cross section of the first groove are both semicircular;the tenon can be embedded into the first groove and can rotate in the first groove; a second groove is formed in the concave surface of the first groove in the length direction of the corrugated pilebody in a penetrating mode; a first radius of the first groove is larger than a second radius of the second groove; and the second groove is used for filling with a water-meeting water-stopping adhesive. The invention further provides the preparation method of the prestressed concrete corrugated sheet pile. According to the prestressed concrete corrugated sheet pile, damage to the joint of the corrugated sheet pile in the transportation process is avoided, and the soil blocking and water retaining effects of the corrugated sheet pile are improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prestressed concrete corrugated sheet pile and a preparation method thereof. Background technique [0002] Prestressed corrugated sheet pile is a new type of retaining structure, which can be widely used in foundation pit support, municipal pipe culvert, bridge tunnel, river revetment, cofferdam slope protection, embankment rescue, port wharf, roadbed slope protection retaining soil, farmland Water conservancy construction and other projects. The corrugated sheet pile is made by pre-tensioning prestressed steel bars, which has the advantages of large soil retaining section, good section mechanical properties, short construction period, good durability, wide construction range, good visual effect, flexible engineering design pile arrangement, energy saving and environmental protection, etc. [0003] At present, the connection of prestressed corrugated sheet pil...
