Abstract
The invention provides a laminate type high-rise platform pile tower crane foundation and a construction method. The method comprises the following steps of before excavating foundation pit earthwork, constructing four concrete cast-in-place piles, penetrating the concrete cast-in-place piles through a foundation bottom plate, wherein a pile top mark is higher than the ground or the close place; casting a reinforced concrete bearing platform on the tops of the four concrete cast-in-place piles, and pre-burying a tower crane foundation section in the bearing platform, wherein the mounting of a tower crane is finished; and before excavating the foundation pit earthwork, downwards excavating along the surrounding of the tower crane bearing platform, casting a concrete laminate structure layer by layer on the concrete cast-in-place piles above the foundation bottom plate, and widely excavating the earthwork in the other area. The problem that the tower crane is poor in stability when the tower crane is used for vertical conveying in a pit construction process is better solved, the tower crane can be mounted to work before engineering piles are not constructed or the foundation pit earthwork is excavated, the time for excavating a foundation pit is effectively shortened, the working efficiency of foundation pit construction is improved, the period for foundation pit construction can be greatly shortened, and beneficial conditions for the smooth perforation of the subsequent procedures are provided.
Description
Technical field
The present invention relates to a kind of tower crane, particularly relate to a kind of laminated board type highrise pile cap tower crane structure and job practices.
Background technology
At present, the comparatively common a kind of mode of large-scale construction method of deep foundation ditch is: before soil excavation, four concrete filled steel tube castinplace piles of elder generation's construction or cast-in-place concrete pile, stake top mark height is located at below the tower crane cushion cap, after treating that tower crane installs, carry out soil excavation again, the castinplace pile of support tower crane successively exposes with the intensification of the soil excavation degree of depth, form destabilizing factor, for addressing this problem, need between four steel tube concrete piles or concrete pile, to form bridging, increase the resistance to overturning of high stake part with the steel pipe welding.Though this method has increased the stability of tower crane, increase welding sequence, increased a large amount of other operations such as steel work welding engineering amount, make tower crane be subjected to certain limitation service time.
Summary of the invention
In view of the existing technical problem that exists, the invention provides a kind of Stability Analysis of Structures, firmly, the efficiency of construction in the safety, raising foundation ditch, and easy construction, laminated board type highrise pile cap tower crane structure with low cost.
Laminated board type highrise pile cap tower crane structure of the present invention, comprise four cast-in-place concrete piles that are arranged in the foundation ditch, described cast-in-place concrete pile runs through sole plate, the stake top of described cast-in-place concrete pile is installed with a steel concrete cushion cap, be installed with tower crane joint on the described steel concrete cushion cap, be on the cast-in-place concrete pile of described sole plate top and be formed with plural layer of concrete plated construction at interval, and described cast-in-place concrete pile is arranged in the described layer of concrete plated construction.
The length that described cast-in-place concrete pile is positioned at the following anchoring section of sole plate is not less than 2 with the length ratio that exposes to the revealed section of foundation ditch.
Described layer of concrete plated construction comprises the reinforced mesh of double-layer double-direction.
Laminated board type highrise pile cap tower crane job practices of the present invention may further comprise the steps:
Before pit earthwork excavation, four cast-in-place concrete piles of construction make it run through sole plate earlier, a stake top mark high position in ground surface or near;
Build the steel concrete cushion cap four cast-in-place concrete pile stake top casting, pre-buried tower crane joint is finished tower crane and is installed in cushion cap;
The excavation pit earthwork downwards around the tower crane cushion cap, and on the cast-in-place concrete pile of described sole plate top concreting veneer structure successively, large tracts of land is excavated other zones cubic metre of earth again.
The length that described cast-in-place concrete pile is positioned at the following anchoring section of sole plate is not less than 2 with the length ratio that exposes to the revealed section of foundation ditch.
Described layer of concrete plated construction comprises the reinforced mesh of double-layer double-direction.
The present invention makes its beneficial effect that has be owing to adopt above technical scheme:
Behind construction and mounted castinplace pile and concrete bearing platform, earth excavation is built then and is formed the plural layer veneer structure downwards, finishes the installation of tower crane.The present invention is by being arranged on each plated construction layer by layer on four castinplace piles, make tower crane Stability Analysis of Structures of the present invention, firmly, safe, compare other highrise pile cap easy constructions, with low cost, preferably resolving in the foundation pit construction process overall process uses tower crane to carry out vertical transport, the difficult problem of tower crane poor stability, engineering piles do not construct or pit earthwork excavation before just can install tower crane in advance and turn round, effectively shortened the excavation of foundation pit time, improved the operating efficiency of foundation pit construction, can shorten the foundation pit construction duration in a large number, carrying out smoothly for subsequent handling provides advantage.
