Abstract
The invention discloses a lifting method of a large-scale caisson. The lifting method comprises the steps of firstly, laying a corresponding number of flat air bags on a prefabrication yard accordant with prefabrication of the large-scale caisson according to the size of the caisson to be prefabricated, and laying iron or wood formworks between adjacent flat air bags for leveling up; then, prefabricating the caisson on the surfaces of the flat air bags and cushion blocks; after prefabrication of the caisson, inflating the flat air bags simultaneously, lifting for 15-25cm to enable the caisson to break away from the cushioning blocks, and placing a support device at the bottom of the caisson; and removing the flat air bags after deflation to complete the lifting of the prefabricated caisson. According to the technical scheme, the lifting method has the advantages that the cost is low, the efficiency is high, lifting grooves are not required to be reserved, construction costs of the prefabrication yard are saved, the method is simple and easy, the construction cycle is greatly shortened, the utilization rate of the prefabrication yard is improved, the limitation of terrains to caisson prefabrication is avoided and the like.
Description
Technical field
The present invention relates to a kind of large scale prefabricated raising method, specifically, relate to a kind of raising method of prefabricated caisson.
Background technology
At present, the raising method of Large Caisson has two kinds: the one, on the place of precasting yard, reserve the jacking groove according to caisson area, weight, cover the load-bearing cover plate, in groove, place the column type hoisting gasbag, after treating that caisson is prefabricated and finishing, utilization is placed on the air bag of jacking groove with caisson jack-up, utilizes carrying air bag and hoist engine that caisson is removed then; The 2nd, the steelframe of placing with i iron weldering system on the level land of precasting yard replaces the jacking groove, at the prefabricated caisson of i iron steelframe loam cake template, transfer top set at i-beam frame and rise air bag, prop up pad after the jacking, withdraw the i iron steelframe, utilize scroll airbag and hoist engine that caisson is removed.There is following shortcoming in above-mentioned two kinds of methods:
1, waste time and energy, jacking groove and cover plate that need prefabricated load is very high on precasting yard, the precasting yard construction period is long, and the place effective rate of utilization is low, and caisson must be in the production site that is provided with the jacking groove, and production efficiency is low;
2, use the i iron steelframe, though reusable and reduce the precasting yard cost, relatively heavier, deficiency such as infusion of financial resources is big first, cost is high and occupied ground is big;
Though 3, above two kinds of methods are in extensive use at present, its efficient, benefit and defective manifest gradually.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defective, and a kind of raising method of time saving and energy saving, Large Caisson that cost is low is provided.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of raising method of Large Caisson is characterized in that, this method may further comprise the steps:
A, in the size that meets on the prefabricated precasting yard of Large Caisson according to prefabricated caisson, lay the flat air bag of respective numbers, lay iron between the adjacent flat air bag or wooden form is leveled up;
B, prefabricated caisson are at the surperficial prefabricated caisson of flat air bag and cushion block;
C, jacking, caisson is prefabricated finish after, give flat airbag aeration simultaneously, jacking 15-25cm, caisson breaks away from cushion block, places bracing or strutting arrangement in the bottom of caisson;
D, withdraw flat air bag, will remove behind the flat air bag deflation, finish the jacking of prefabricated caisson.
As a kind of improvement:
The upper surface of described every flat air bag is provided with guard shield.
The width of described flat air bag is 1-1.2 rice, and thickness is 0.025 meter, operating pressure 3Mpa, every meter air bag bearing capacity 644kn/m when working depth is 0.5 meter.
As further improvement:
Described bracing or strutting arrangement is some stocks that are positioned at the caisson bottom, between adjacent stock spacing is arranged.
Place a scroll airbag every two meters below the described caisson.
Owing to adopted technique scheme, raising method of the present invention has the following advantages:
(1) reduces cost, raise the efficiency, need not reserve the jacking groove, saved the construction cost of precasting yard, and improved utilization rate and the production capacity of precasting yard greatly;
(2) use the template cushion block than using the i iron steelframe, cost reduces several times, and flat air bag is lower than round balloon construction cost;
(3) method is simple, does pre-lifting method with flat air bag, has shortened the construction period greatly, and the utilization rate of raising precasting yard and landform are to the prefabricated restriction of caisson.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
