Pile foundation static load test method adopting construction pile as anchor

Abstract

The invention discloses a pile foundation static load test method adopting a construction pile as an anchor, and the method comprises the following steps: S1, construction preparation: preparing instruments, meters, data recording books and other test articles for pile foundation static load test so as to be used for process measurement and data recording of the pile foundation static load test, guarantee the accuracy and uniformity of the test, and improve the test efficiency; and S2, a tester arrives at a test site after completing the step S1, installs and debugs the carried instruments and meters, and investigates the faults of the instruments and meters, so that the accuracy of test data is ensured, test errors are reduced, the method is economical and rapid, is much more convenient than a stacking method adopted in the past, is not limited by geographic positions, and is suitable for popularization and application. Before pile foundation concrete is poured, the embedded steel strands are embedded according to the required number and position, when the concrete reaches the age, a crane installs the girder, all the girders can be installed in place within one day, official loading can be conducted in the morning of the next day, and operation is convenient and fast.

Description

technical field [0001] The invention discloses a static load test method for pile foundations by using construction piles as anchors, and belongs to the technical field of static load tests for pile foundations. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountain streams, unfavorable geology or meet other traffic needs to erect buildings that make traffic more convenient. Bridges generally consist of superstructures, substructures, supports and auxiliary structures. , the upper structure, also known as the bridge span structure, is the main structure for crossing obstacles; the lower structure includes the abutment, pier and foundation; Refers to the bridge head slab, conical slope revetment, bank revetment, diversion works, etc. After the super...

Problems solved by technology

In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountain streams, poor geology or meet other traffic needs to erect buildings that make traffic more convenient. Bridges generally consist of superstructures, substructures, supports and auxiliary structures. , the upper structure, also known as the bridge span structure, is the main structure for crossing obstacles; the lower structure includes the abutment, pier and foundation; Refers to the bridge head slab, conical slope revetment, bank revetment, diversion works, etc. After the super large bridge and bridge construction unit completes the pile foundation pouring concrete, it must sample the pile foundation for bearing capacity test. In the past, the heap load method was used. However, The surcharge method is limited by the location of the site, and the time for burying sandbags is also very long, usually one week. There are also many materials and equipment, such as main beams, secondary beams, and supporting piers. The test method is complicated and inconvenient to use.
