The invention discloses a prefabricated pipe pile welding seam quality detection device and a detection method thereof. The detection device is equipped with a rubber holster on the outside of each welding seam, and according to the welding seams at different depth positions, thin water injection hoses of corresponding lengths are configured, and the upper ends of each thin water injection hose are connected to the The pressurizing device with the hydraulic gauge on the ground is connected, and the lower ends are respectively wrapped in the rubber sheaths socketed outside the welding seams at different depths. Therefore, pressurize and inject water into the rubber holster at the location of the welding seam through the corresponding water injection thin hose, and then read the reading of the hydraulic gauge after applying a certain pressure, and the quality of the welding seam at the location can be judged according to the change of the reading of the hydraulic gauge . It can be seen that the present invention can detect multiple welding seams of different depths separately, avoiding mutual interference between the welding seams; no hole cleaning operation is required, and the detection efficiency is high and the cost is low.
Description
technical field [0001] The invention relates to a prefabricated pipe pile welding seam quality detection device and a detection method thereof. Background technique [0002] Prefabricated tubular piles are widely used in civil engineering because of the advantages of reliable pile quality, convenient transportation, fast construction speed, and low cost per unit bearing capacity. Restricted by conditions such as hoisting, transportation and pile sinking machinery, the length of single-section pipe piles is generally not large, and multi-section pipe piles are often welded together for use in projects. Workers' welding skills and on-site operating conditions will affect the welding quality. Pile sinking by hammering has a great impact on the pile, especially when passing through uneven soil layers, which may cause cracks at the welding seam; The effect can also lead to impaired quality of the weld or even desoldering. The quality defects of the welded seam will reduce the b...
