Embodiment Construction
[0033] The technical requirements for tower crane foundation construction will not be repeated in the present invention, and the structure involved in the present invention will be emphasized.
[0034] Such as Figure 1-5 As shown, the steel lattice column 6 composite tower crane foundation structure in the foundation pit described in this embodiment includes the prefabricated cast-in-situ piles 1 of the foundation pit and the foundation pit bottom 11, and the cast-in-place piles 1 are connected sequentially from bottom to top. Steel lattice column 6, steel column 15, cap 9 and tower crane pre-buried joint foundation 10, steel lattice column 6 is provided with concrete core column 5, and cast-in-place pile 1 is provided with a plurality of internal longitudinal reinforcements forming a reinforcement cage 18. The steel lattice column 6 is welded and fixed to the reinforcement cage inside the cast-in-place pile 1, and the welding section between the cast-in-situ pile 1 and the s...

The invention discloses a steel latticed column combined-type tower crane infrastructure in a foundation pit. The steel latticed column combined-type tower crane infrastructure comprises the foundation pit and cast-in-place piles prefabricated at the bottom of the foundation pit, wherein the cast-in-place piles are sequentially connected with steel latticed columns, steel columns, bearing platforms and tower crane pre-embedded joint foundations from bottom to top, concrete core columns are arranged in the steel latticed columns, multiple in-pile longitudinal ribs forming a steel bar cage are arranged in the cast-in-place piles, the steel latticed columns are welded and fixed to the steel bar cage in the cast-in-place piles, detachable holding hoops are fastened to the sections, welded with the steel latticed columns, of the cast-in-place piles and are fixed through holding hoop bolts, the problems of large tower crane foundation construction difficulty and the like are solved by utilizing the characteristics of light weight, small material consumption, convenient construction operation and the like of an assembled hollow zigzag bearing platform, and the steel latticed column combined-type tower crane infrastructure has better technical and economic benefits. The sections, connected with a steel latticework, of the piles are reinforced by adopting post-mounted detachable holding hoops, and the structural stability is increased. The prefabricated concrete core columns are post-mounted in the steel latticed columns to increase rigidity.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a steel lattice column composite tower crane foundation structure in a foundation pit and a construction method. Background technique [0002] With the rapid development of the national economy, communication technology and control technology, the rise of various high-rise, super high-rise buildings and large-scale construction projects, the monitoring technology of tower cranes is also constantly improving. The requirements for amplitude, wind speed and lifting moment are getting bigger and bigger, and they are more and more widely used in the construction process of modern buildings. [0003] At present, most of the tower cranes (hereinafter referred to as tower cranes) used in China are constructed according to the equipment foundation provided by the tower crane manual. Due to the different needs of the construction site and the different geological conditions of the s...
