Concrete pile durability repairing module

Abstract

The invention relates to a concrete pile durability repairing module, and belongs to the technical field of concrete foundation piles. The concrete pile durability repairing module comprises a plurality of repairing units and connecting rods for connecting the repairing units in series sequentially. Each repairing unit comprises a shell and a positioning ring, wherein the shell is of a columnar structure and has a fan-shaped annular cross section. The connecting rods are positioned in the shells and connect the shells in series sequentially in the length direction of the shells. Material injection holes are formed in the arc side surfaces of the shells. The two inclined side surfaces and the bottom side surface of each shell are provided with a plurality of seepage holes which are uniformly distributed in the two inclined side surfaces and the bottom side surface of the shell. Springs are fixedly arranged at the two ends of each connecting rod. The repairing module provided by the invention can be used for quickly repairing a concrete pile underwater, can position and repair a part to be repaired more easily, improves the repairing efficiency of the concrete pile, and has a betterrepairing effect.

Description

technical field [0001] The invention belongs to the technical field of concrete pile foundations, and in particular relates to a durable repair module for concrete piles. Background technique [0002] Due to various reasons such as complex geological conditions, deviations in survey and design, improper construction operations, and other uncontrollable factors, concrete foundation piles, especially concrete driven piles, have more or less construction defects during or after construction. Cracks are the most common one. The existence of cracks will inevitably affect the concrete strength and durability of foundation piles, and some may even cause serious leakage, affecting the safety and normal use of components. Therefore, the defects must be repaired. According to different locations, the pile foundation of port engineering can be roughly divided into atmospheric area, water level fluctuation area, underwater area and submud area. The cracks in different regions have gre...

AI Technical Summary

Problems solved by technology

When the crack is underwater, a layer of water will be formed on the interface between the repairing adhesive material and concrete, which is equivalent to forming a weak interlayer. Without special measures, the bonding effect will be reduced, resulting in poor repairing effect

Moreover, the working environment of underwater repair is harsh, and generally divers directly carry out underwater operation and construction. If there is no special technology, the repair work is more difficult

[0003] For the repair of concrete piles in the prior art, grooves are first made in the cracks of foundation piles, and then repaired with repairing materials. How to improve the durability of concrete piles, most researchers are improving the repairing materials. Increase the bonding strength between repairing materials and concrete in water, but because the cracks of underwater concrete foundation piles are sometimes large in scale, the grooves on the surface of concrete piles are also relatively large, so a large amount of repairing materials need to be filled, for water In short, this kind of project is relatively large. Simply improving the bonding strength between repair materials and concrete can no longer meet the conditions for large-area repair. Under the influence of large water flow, the repair efficiency will be significantly reduced.
