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. Pile bearing capacity should be carried out the following calculations and stability computations are based on the specific conditions: ① should be vertical and horizontal bearing capacity calculation of pile foundation pile according to functions and force characteristics were calculated. ② response pile structure and caps bearing capacity calculations; for the pile side undrained shear strength of less than 10kPa and an aspect ratio of greater than 50 piles pile buckling checking should be carried out; for precast concrete piles should be lifting, transportation and hammering action carried pile Bearing Capacity; for steel pipe pile should be checking the local buckling. ③ When the presence of the pile below the lower end of the soft underlying layer should be carried out under weak lying Bearing Capacity; located slope, shore overall stability of the pile should be checking. ④ for the anti-floating, uplift pile should be carried out and the group piles foundation piles pullout capacity calculation. For the pile ⑤ seismic zone seismic capacity should be checking.

The designer usually after the completion of the preliminary design, construction drawing issued before the official, will require the construction unit in accordance with the results of the preliminary design, trial piles. Whether used as construction (2) test pile position (generally provide CAD drawings clear) Kaifeng construction engineering inspection, and clearly after the test pile; (1) the number of test pile construction engineering test and trial pile method: test piles generally include the following notice pile; (3) Test Piles large drawing: generally contain pile length, pile diameter, pile reinforcement, pile bearing stratum and buried (rock) depth; (4) test piles requirements: test pile load value Zhongmou construction engineering inspection, general pile load bearing capacity is the value of two times the destructive test pile to be loaded to damage, confirmatory test pile is generally loaded to 2 times to stop. Building Pile generally only provide carrying capacity, QS curve; the transportation industry in general will be asked to provide the bearing capacity, Q S curve, layered side, tip resistance. Xinzheng construction engineering inspection _ China Risheng detection (certified) _ construction engineering inspection provided by the Construction Engineering Testing Co., Ltd. Henan malpractice.
