Embodiment

[0026] Embodiment: A kind of construction method of tower crane foundation

[0027] (1) Formulate the foundation position of the tower crane

[0028] Determine the type of tower crane used and the location of the tower crane according to the drawings, manpower and material resources, and formulate the location of the tower crane foundation using the structural raft foundation.

[0029] (2) Earth excavation

[0030] Excavate the earthwork according to the design requirements of the drawings. The height and soil layer must meet the requirements of the design and the bearing capacity of the foundation. Excavators are used for mechanical excavation, and the construction is carried out in sections. 400m thick earthwork is left at the bottom of the foundation pit, of which 200m thick original soil layer, 200m thick The thick loose soil layer shall be manually cleared up to the bottom elevation of the concrete cushion, and transported by car while the original soil layer above 200m ...

Abstract

The invention discloses a method for constructing a tower crane foundation. According to the technical scheme, the tower crane foundation is constructed by using a structure raft foundation. The method comprises the following steps of: determining the position of the tower crane foundation, excavating soil, constructing a foundation bed, constructing and plastering brick moulds, performing foundation water prevention, constructing a foundation water prevention protective layer, performing foundation setting-out, bundling foundation base plate lower steel bars, preembedding and assembling tower crane accessories; bundling foundation upper steel bars, assembling steel plate water-stop belts and templates, performing concrete construction on the tower crane foundation, roughening and performing water prevention treatment on concrete surface of the tower crane foundation and a structure raft. By the method, the construction process is simplified, the construction cost is reduced, and the tower crane foundation is integrated with the structure raft and stressed in a relatively balanced and safe mode.

Description

technical field [0001] The invention relates to the technical field of tower crane foundations, in particular to a structural main body with a raft foundation, which needs to be installed with a tower crane for vertical transportation engineering tower crane foundation construction. Background technique [0002] Because the heavy objects are lifted by the suspended boom, the tower crane has a very large dumping moment, and the requirements for the bearing capacity of the foundation are also high. Therefore, the foundation of the tower crane is very important and is a necessary condition for maintaining the safe operation of the tower crane. Tower crane foundations are generally poured into concrete bases, and the length, height, width, and reinforcement of the base need to meet the requirements for tower crane overturning stability, foundation bearing capacity, and base crack resistance. The traditional tower crane foundation is constructed outside the structural raft founda...
