Walking type detection platform for static load of engineering foundation piles

Abstract

The invention discloses a walking type detection platform for the static load of engineering foundation piles, which comprises a supporting platform movably supported on two long boats and two short boats, wherein the two short boats are respectively arranged at two ends of the supporting platform, and a short-boat walking vehicle is arranged on each short boat and is fixedly connected with a short-boat slewing platform; vertical lifting hydraulic cylinders mounted on the supporting platform is hinged to the short-boat supporting platforms; the short-boat slewing platforms are hinged to the short-boat supporting platforms through swing pin shafts; two long-boats are respectively arranged on two sides of the supporting platform; each long boat is provided with two movable long-boat walking vehicles which are hinged to the lower ends of the corresponding legs of the long boats; the legs of the long boats are mounted on the supporting platform through beams of legs of the long boats; long-boat walking hydraulic cylinders are arranged between the long-boat walking vehicles and the long boats; a crane is mounted on the supporting platform. The detection platform can perform self-propelled move as a whole, requires no repetitive construction and hoisting, and has the features of safety in use, reasonable structure, high operating efficiency and the like.

Description

technical field [0001] The invention relates to a building construction testing machine, in particular to a testing device for testing the static bearing capacity of foundation piles during construction of pile foundations in construction engineering. Background technique [0002] Pile foundation is a form of foundation widely used in construction projects. As an important part of the main body of the structure, the pile foundation is directly related to the overall safety of the building. Differences in geological conditions, construction technology, construction management level, and pile foundation raw materials will affect the quality and quality of the pile. Single pile bearing capacity; in order to ensure the quality of pile foundation engineering, it is necessary to carry out single pile bearing capacity testing or sampling testing for pile foundation engineering in actual projects. The testing items mainly include single pile vertical compressive static load testing ...

AI Technical Summary

Problems solved by technology

Therefore, the existing pressure platform reaction device requires the tracking and cooperation of special equipment such as transport vehicles and cranes during operation, and needs to continuously rebuild the platform and reload and unload the counterweight, which consumes a lot of manpower and material resources. Material transfer and construction The repeated workload is heavy, not only the test cost is high, the detection time is long, the operation efficiency is low, and the labor intensity is high. There are many safety weaknesses in the process of transshipment, loading, unloading and stacking, which are easy to cause safety accidents and have a low safety factor.

At the same time, the existing pressure platform reaction force device is spliced ​​on-site from parts, and the integrity is not strong, and it is easy to be lost during transfer, which increases the working time and difficulty of rebuilding. The detection of existing foundation piles has obviously affected Construction progress and efficiency
