End is equipped with the boss that can be caught in the card slot.
Further, the annular slab inner wall is equipped with arc groove, and the arc groove corresponds to the rod piece.
Further, the arc groove longitudinal arrangement is three, has first on three rod pieces of longitudinal arrangement
Through-hole, the second through-hole and third through-hole, the first through hole, second are led to when three rod pieces of longitudinal arrangement are in step arrangement
Hole and third through-hole successively correspond to up and down and can be inserted into vertical bar.
Compared with the prior art, it the utility model has the following beneficial effects: the utility model is before laying foundation, first excavates
Circular Pit simultaneously forms Circular Pit side wall, and then the round prefabricated component is placed in foundation pit, then true according to foundation pit size
The arc length of the fixed annular slab makes radius of the foundation pit radius equal to arc panel, will be described in four pieces after the annular slab is successful
Arc panel is placed in foundation pit and circle of encircling a city, and the telescopic cylinder is then put in the groove keeps the telescopic rod corresponding
The perforation, while wherein one end of the rod piece is protruded into the perforation, starting multiple telescopic cylinder work makes institute
It states telescopic rod and protrudes into the perforation and then the rod piece is pushed to be pushed to the arc panel and squeeze foundation pit side-wall until can not
Subject to squeezing again, four arc panels squeezed after the completion of finally on the same circle, can not pass through in the same circle
Excavating the mode banketed makes four arc panels uniquely on same circle, after all arc panels are pushed against, according to adjacent
The distance between two described arc panels customize the length of the fastener, are then caught in the card slot by the boss thus will
Four arc panel clampings, then take out thus the telescopic cylinder, in Xiang Suoshu groove and the round prefabricated component
The casting concrete between the arc panel squeezes foundation pit side-wall using the telescopic cylinder to increase foundation pit walls to basis
Pressure increases the stability of tower crane.
The further advantage, target and feature of the utility model will be partially reflected by the following instructions, and part will also pass through
Research and practice to the utility model and be understood by the person skilled in the art.

Specific embodiment
In order to make technological means of the utility model, creation characteristic, reach purpose and effect is more clear and is easy to
Understand, the utility model be further elaborated with reference to the accompanying drawings and detailed description:
The utility model proposes a kind of tower-crane foundation structures, including round prefabricated component 1, telescopic cylinder 2,3 and of annular slab
Rod piece 4, the annular slab 3 are 4 blocks of steel plates, and mutual split forms circle, the circle prefabricated component 1 to every piece of arc panel 3 two-by-two
For reinforced concrete precast member, tower crane build 1 top of round prefabricated component, each corresponding 6 flexible gas of the arc panel 3 in
Four, cylinder 2 and 6 rod pieces 4, every 32 longitudinal arrangements of telescopic cylinder, the telescopic cylinder 2 of 3 of longitudinal arrangement it
Between by timber wedge increase height, the rod piece 4 be solid iron staff, it is described circle prefabricated component 1 be equipped with one circle can place it is described stretch
The groove 5 of cylinder 2, the circle prefabricated component 1 are equipped with the perforation 7 of multiple connection grooves 5, the internal diameter etc. of the perforation 7
In the outer diameter of the rod piece 4, the telescopic rod 8 of the corresponding telescopic cylinder 2 of the perforation 7, wherein one end is located at institute to the rod piece 4
It states in perforation 7,4 other end of rod piece corresponds to 3 inner wall of annular slab, and four annular slabs 3 can piece together a circle
Shape, the annular slab 3 are adjacent to foundation pit side-wall 6, and 3 both ends of annular slab are equipped with card slot 10, and 9 both ends of fastener are equipped with and can be caught in
