Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, to specific embodiment, structure, feature and its effect is proposed according to the present invention, detailed description is as follows.
Referring to Figure 1, the new-type tower crane foundation construction method of first embodiment of the invention, comprising:
A, arrangement and method for construction determine, determine steel lattice column 1 in bored concrete pile 2 and cushion cap 5 in buried depth, 4 position of sustaining wall part, institute
It states the buried depth that steel lattice column 1 is embedded in bored concrete pile 2 and is greater than or equal to 4m.
B, when bored concrete pile 2 is constructed in the pre-buried steel lattice column 1 in 2 top of bored concrete pile;
C, in 1 top construction bearing platform 5 of steel lattice column;
D, increase Construction Support beam 3 with excavation of foundation pit depth, according to 4 position of sustaining wall part in the pre-buried built-in fitting of supporting beam 3;
E, sustaining wall part 4 and built-in fitting, each steel lattice column 1 are connected and fixed;
F, increase with excavation of foundation pit depth, reinforced each steel lattice column 1 under cushion cap 5 using steel.
Refer to Fig. 2, steel lattice column 1 is embedded in the buried depth in cushion cap 5 more than or equal to 0.7m, on steel lattice column 1 with base
Plinth bottom plate overlapping positions are welded with seal ring 2.1 quantity of steel lattice column under cushion cap 5 is four, above supporting beam 3
Cushion cap 5 is formed by C40 concreting.Steel are angle steel and steel plate.
It step C, further include installation tower crane between D.
Step F includes that each steel lattice column 1 under the cushion cap 5 is connected as entirety using steel.
Fig. 3 is referred to, steel lattice column 1 is embedded to bored concrete pile 2 not less than 4m and the top of bored concrete pile 2 is located at sole plate hereinafter, mixed
Solidifying earth foundation is cast on steel lattice column 1, and steel lattice column 1 is embedded in cushion cap 5 no less than 700mm, and cushion cap 5 is having a size of 5*5*1.5m
Using C40 concrete.Angle steel reinforcement of weld is used inside 5 construction method steel lattice column 1 of cushion cap, outside is reinforced and week using sustaining wall
Side support system reinforcement by connection, supporting beam 3 according to tower crane position have planned sustaining wall position before constructing, and supporting beam 3 will help when constructing
Wall connector is embedded in supporting beam 3, connects built-in fitting on sustaining wall part 4 and supporting beam 3 after the completion of the construction of horizontal shore 3
Connect, tower crane and inner support system be linked to be entirety, improve the stability of tower crane entirety, when subsequent horizontal inner support construction be also as
This.To keep tower crane overall stability, every 3m setting downwards is pushed up from cushion cap 5 and is reinforced together, reinforcing member uses 18 bugle steel and 20
Thick connecting plate connects 5 lower four steel lattice columns 1 of cushion cap integral, and specific strengthening construction is shown in attached drawing, it is ensured that in allocation and transportation material and
Tower crane stability is kept under typhoon.
For solve traditional tower crane foundation at the drawbacks of now invent a kind of novel tower crane foundation construction method, the present invention adopts
Steel lattice column 1 is used to be combined with concrete foundation as tower crane.Have following advantages compared with traditional tower crane:
1, when using novel tower crane foundation construction method, tower crane construction can be in support pile or Construction of Engineering Pile stage soil
Side installs tower crane before excavating, it is ensured that material vertical transport is solved the problems, such as when foundation pit support construction.
It 2, can be in sole plate range when compared with bored concrete pile 2 or prefabricated tubular pile using novel tower crane foundation construction method
Or in structural slab altitude range, seal ring is welded in lattice column corresponding position, is avoided at the bottom of indwelling construction joint leads to the later period
The hidden danger of plate leakage.
3, using novel tower crane foundation construction method, contrary sequence method can be used steel lattice column 1 during earth excavation
Reinforcement of weld is carried out, it is poor that traditional cast-in-place concrete pile 2 or prefabricated tubing string reinforce more difficult and presentation quality.
4, heavy mechanical equipment is not necessarily to when removing using the more traditional tower crane foundation construction of novel tower crane foundation construction method
It is abolished, after the completion of tower crane dismounting, steel lattice column 1 can be cut off, can be selected according to the case where means of transport using gas cutting
Select excision size.
In the present invention, using novel tower crane foundation construction method compared with traditional tower crane, no matter Saving in time costs,
Security risk control, fund cost benefit and later period abolish and have all obtained significant raising.
More than, it is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, although this
Invention has been disclosed in a preferred embodiment above, and however, it is not intended to limit the invention, any person skilled in the art,
It does not depart within the scope of technical solution of the present invention, when the technology contents using the disclosure above make a little change or are modified to equivalent
The equivalent embodiment of variation, but without departing from the technical solutions of the present invention, according to the technical essence of the invention to the above reality
Any simple modification, equivalent variations and modification made by example are applied, all of which are still within the scope of the technical scheme of the invention.
