Pile foundation repairing method based on constructional engineering

Abstract

The invention discloses a method for repairing a pile foundation based on a construction project, comprising the following steps: S1: preparing an ultrasonic detector, using the ultrasonic detector to scan the structure of the damaged part of the pile foundation, and detecting the material density of the pile foundation, and then Send the scan results and test results to the computer, S2: Make a repair plan document on the computer, and then confirm it by the engineer, and then mix the repaired materials, use sand, cement and mortar to add water to mix into concrete, and the concrete is The quality and density are similar to those of the original pile foundation. S3: Design the repair steps according to the repair plan, S4: Carry out the repair steps, and S5: Use materials to seal the repaired position. The invention can scan and detect the damaged part of the pile foundation, can also design the best repair scheme according to the detection result, and can repair the damaged part of the pile foundation, reduce labor, improve the efficiency of repair and the repair efficiency. quality.

Description

technical field [0001] The invention relates to the technical field of building pile foundation restoration, in particular to a construction engineering-based pile foundation restoration method. Background technique [0002] The pile foundation is composed of the foundation pile and the cap connected to the top of the pile. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and bears If the bottom of the platform is above the ground, it is called a high cap pile foundation, and the building pile foundation is usually a low cap pile foundation. [0003] The patent document with the application number 201610009978.3 proposes a building pile foundation repair process, which is used to solve the problem that the quality of cast-in-situ piles is not up to standard when the wall of the excavated hole collapses. The technical def...

Problems solved by technology

[0003] The patent document with the application number 201610009978.3 proposes a building pile foundation repair process, which is used to solve the problem that the quality of cast-in-situ piles is not up to standard when the wall of the excavated hole collapses. The technical defects of cost increase and extended construction period, but it does not solve the problem that the pile foundation will be corroded due to external factors after a long period of use, resulting in damage to the pile foundation and repairing, so we propose a pile foundation repair based on construction engineering method is used to solve the problems raised above
