Hebei Xinhe Jizhong pile driver is located on the north side of National Highway 308 in Baishen Industrial Development Zone, Xinhe County, Xingtai City. It is adjacent to the Qingyin Expressway and has convenient transportation. It is a professional manufacturer specializing in the development, production, and sales of various pile drivers and steel reinforcement series products.
We specialize in producing various types of pile driving machines, including CFG pile driving machines, hydraulic walking type long spiral drilling machines, and submersible engineering drilling machines. Our main products include CFG series long spiral drilling machines with effective depths of 18, 20, 23, 26, 28, 30, and other models, which are operated by electric motors and hydraulic machines, and operate in a walking style. When working, a long spiral drilling rig is used to drill to the design elevation. When lifting the drill, concrete is poured into the pile through a concrete conveying pump (or steel cage can be inserted later), and the drilling and pile formation are completed synchronously by one machine. Our products have over 10 series and 30 varieties, selling well in 30 provinces, cities, and regions in China and exporting to 7 countries.
The quality of pile foundation depends on many factors such as survey, design, and construction. Due to the strong concealment of the project, quality accidents are prone to occur during construction. The correct analysis and handling of quality accidents often affect the safe use of the building, engineering cost, and construction period. In severe cases, even the entire building may be destroyed. The main causes of pile foundation quality accidents are as follows.
(1) Measurement and layout errors result in the entire building being misaligned or the pile position deviating too much.
(2) The bearing capacity of a single pile does not meet the design requirements.
(3) Pile interruption accident. If the bored pile collapses or gets stuck.
(4) The quality of bored pile construction includes excessive sediment thickness, concrete segregation, mud inclusion in the pile body, failure to meet design requirements for concrete strength, and severe displacement and deformation of steel bars.
(5) Broken pile. Out of control of construction quality during pouring concrete, resulting in pile breakage accidents
(6) The pile position deviation during pile foundation acceptance is too large.
(7) The elevation of the top of the bored pile is insufficient. There are three common types, one is lax construction control, and concrete pouring is stopped before reaching the design elevation; Another type, although the elevation reaches the design value, is insufficient due to the thick layer of concrete floating slurry on the pile top, resulting in insufficient elevation of the pile top after excavation.
