Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, glass curtain wall testing, roads and bridges detection, detection of a number of civil air defense projects testing qualification and testing laboratories. Horizontal thrust reaction force may be provided adjacent to pile the main structure of the building is detected, when a reaction force specially set structure, its carrying capacity and stiffness 12 times greater than the test piles. Displacement measurement reference point setting should not be subject tests and other factors factory main structure detection, the reference point should be set in a direction perpendicular to the applied force and displacement in the opposite direction of the test pile side, the reference point and the test pile spacing should not be less than 1 times pile diameter. Between a longitudinal section and the direction of the force sensors buried; measuring pile stress or strain when the principal structural inspection phones, each test section measuring sensor should be symmetrically arranged in the neutral axis away from the tension and compression reinforcement along the direction of the force The angle of not greater than 10 °. In the ground 10 times pile diameter (pile width) of the main part of the force should be encrypted test section, section spacing should not exceed one times the pile diameter; beyond this depth, the test may be appropriate to increase the spacing section. Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, glass curtain wall testing, roads and bridges detection, detection of a number of civil air defense projects testing qualification and testing laboratories. Under normal circumstances, the basic process of pile foundation design are as follows: (1) determine the design level and the pile foundation design principles; (2) type of pile, pile section size, pile length of choice; (3) to determine pile capacity; ( 4) Determine the number of piles and piles of cloth; (5) checking pile group capacity and settlement; (6) Pile each pile and calculation; (7) pile design; (8) Caps Design.
