Problems solved by technology

[0005] The hammer penetration pile tester uses a mechanical dial indicator to detect the penetration degree. Someone must observe the dial indicator at the test pile point, which is unsafe. The resistance strain gauge is pasted on the cylinder surface, and its heat resistance , water resistance, weather

Embodiment Construction

[0023] The present invention is a hydraulic power pile driving machine with hammer penetration test pile. On the basis of the original hydraulic power pile driving machine, a pile-soil system elastic deformation value detection device and a penetration detection device are added, and the stroke Regulators were improved. Furthermore, the product of the present invention can be used as a top-pull hydraulic power pile driver, and can also be used as a hydraulic power pile driver with hammer penetration test piles. When used as a hydraulic power pile driver, the stroke adjustment The device and the penetration detection device are necessary, but the elastic deformation value detection device of the pile-soil system is not needed; when used as a hydraulic power pile driver with hammer penetration test piles, the stroke regulator, penetration detection device , and pile-soil system elastic deformation value detection device is necessary.

Abstract

The invention is a hydraulic power pile driver with hammer penetration pile test function. An elastic deformation detection device and a penetration detection device of a soil-pile system are arranged on a basis of a jacking hydraulic power pile driver; and a stroke adjuster is improved so as to provide the impact energy, the penetration and the elastic deformation of the soil-pile system for a calculating device respectively; thus not only the impact force of each hammer can be calculated and displayed in time to realize visibility of the impact force in a hammering process, which is more convenient and more intuitive than the visibility of the pile driving force of a conventional hydraulic power pile driver, but also a high strain dynamic test capable of replacing a static loading test can be performed after several resting periods when the hammering is stopped; therefore, the construction progress of the pile foundation is quickened, and a great amount of investment is saved for a proprietor.

Description

Technical field: [0001] The invention relates to a foundation engineering machine (abbreviated as a pile machine) used in the construction industry, in particular to a hydraulic power pile driving machine capable of hammering through piles at the same time. Background technique: [0002] After the prefabricated concrete piles are put into the soil and formed into piles, a number of piles must be taken in proportion to do static load tests to test the vertical ultimate bearing capacity of a single pile. According to the requirements of No. 9-2 single pile bearing capacity test in JGJ94-94 mandatory industry standard, single pile static load test or reliable dynamic test can be carried out. Developed countries have already used dynamic test to test single pile bearing capacity. Among the many dynamic test methods, the hammer penetration method (abbreviated as the hammer penetration method) is widely used in our country. The current common practice is to drive the pile into the...
