How many meters is the tower crane installed on the edge of the deep foundation pit?
If you set the tower crane foundation in the foundation pit, which is based on another piling, the general is to help the wall of the tower crane (unless your project in the free height under it), so far away from the foundation by the wall distance set.The two tower cranes are all supported by piles and steel lattice columns in the foundation pit. The distance is determined by the distance between the outer edge of the main structure and the supporting wall.
Tower crane foundation, if set up in the foundation pit, the foundation is to pile other, general tower crane is to support the wall.Therefore, how far away from the foundation pit is determined by the distance from the retaining wall.According to the industry standard "technical specification for concrete foundation of tower crane tower crane foundation installation" (JGJ/T187-2009), the installation of tower crane foundation concrete should reach more than 80% of design strength, the tower crane foundation concrete design strength should reach 100%.
Hello, it depends on your design requirements, generally have the pit bottom, straight out of a tower crane base do. Or elevator shaft is also more. Generally, the foundation pit is shallow foundation pit or relatively small foundation pit.
