Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of pipe pile butt joint, concretely relates to a connector for pipe pile butt joint. BACKGROUND

[0002] In geotechnical engineering construction, the length of prefabricated concrete pipe pile is difficult to directly meet the needs of building construction, so multiple piles are often combined to meet the construction needs. However, the connecting part between the two piles is extremely vulnerable to damage due to tension, bending and shear forces, and in the construction process, the upper and lower piles need to be kept relatively vertical and accurately aligned.

[0003] 1. Anchor rod static pressure pile method is a building method for foundation treatment and reinforcement. Compared with other reinforcement methods, it has the characteristics of no noise, no vibration, simple equipment, easy operation, flexible movement and small construction space. In the anchor rod static pressure pile method, the anchor rod static pressure pile is the main part of the ground and then the concrete is poured. For example, the patent with the application publication number CN110805030A discloses an anchor rod static pressure pile, and the specification paragraph 0004 discloses that the grouting pipe group is inserted vertically from the upper end of the pile body into the pile body and used for grouting the inner cavity of the pile body.

[0004] However, in actual use, the adjacent two sections of the static pressure pile are generally connected by welding when being pressed into the ground, and the construction method is relatively cumbersome, therefore, it needs to be improved.

[0005] 2. In the process of building construction, the connection between prefabricated concrete components is indispensable. For example, the patent with the application publication number CN205712152U discloses a prefabricated pile reinforcing structure and a durable pile foundation, and the specification paragraph 0024 discloses that the pile sleeve is wrapped around the outer surface of the pile head with thin iron sheet, and the pile sleeve only plays the role of preventing the leakage of cement slurry at the pile end and heat dissipation during welding, and does not transmit tensile force between the end plate.

[0006] However, in actual use, when the prefabricated pile needs to withstand a large amount of tensile force, the existing sleeve structure cannot share the tensile force received by the main reinforcement of the pile body, so the pile welding position may be damaged under tensile, bending or shear working conditions, and the main reinforcement of the pile body is prone to breakage.

[0007] Therefore, a connector for pipe pile butt joint is proposed to solve the above-mentioned drawbacks. UTILITY MODEL CONTENTS
