Description

TECHNICAL FIELD

[0001] The present application relates to the field of reverse osmosis membrane purification technology, and particularly relates to a concrete construction equipment. BACKGROUND

[0002] In the post-tensioned prestressed concrete structure during the construction of a building, especially a bridge, the joint action between the prestressed tendon and the concrete and the rust and corrosion prevention of the prestressed tendon are realized by filling the embedded duct with cement slurry. In order to ensure the construction quality of the post-tensioned prestressed concrete structure, the embedded duct is embedded into the beam body in the box girder during the construction process to form a duct for the working environment of the prestressed steel strand, and then the concrete grouting is performed in the prestressed corrugated pipe after the beam body is poured. The existing technology often uses a feeding pump to pump the concrete slurry directly into the prestressed corrugated pipe until it is flushed out from the other end.

[0003] However, the existing technology has some disadvantages in the long-term use, such as: 1. For the prestressed corrugated pipe with a long construction environment length, the whole is distributed in a concave curved shape, and the large-diameter material in the concrete grouting middle section is blocked in the inner layer of the corrugation, so that the consistency at the rear end of the grouting path is relatively high, which causes the air in the pipe to be squeezed into the concrete, and then causes the entire pipeline to have a filling defect; 2. During the fixed embedding process of the prestressed corrugated pipe, the prestressed corrugated pipe is damaged. In order to avoid subsequent grout leakage, the damaged part needs to be repaired by using a reinforcing steel bar or a shearing reinforcement. However, the external repair method has high requirements for the repair environment of the damaged part, and once the debris is not treated, the sealing and continuity of the pipeline cannot be guaranteed.
