Abstract
At present, construction of cross-sea bridges is in the industrialized production stage, however, due to the fact that water stop at the junction between a preformed hole of a prefabricated pile cap and a pile foundation is not achieved effectively, the industrialized progress of the bridges is hindered. The invention provides a method for water stop construction at the junction between the preformed hole of the prefabricated pile cap and the pile foundation. The method for the water stop construction at the junction between the preformed hole of the prefabricated pile cap and the pile foundation aims to achieve the water stop at the junction between the preformed hole of the prefabricated pile cap and the pile foundation. According to the method for the water stop construction at the junction between the preformed hole of the prefabricated pile cap and the pile foundation, an upper movable flange ring and a lower movable flange ring are arranged in the preformed hole of the prefabricated pile cap, the distance between the upper movable flange ring and the lower movable flange ring is about 40cm, the upper movable flange ring and the lower movable flange ring are respectively provided with a water stop rubber belt, a grouting pipe and a grout outlet pipe are pre-buried in the middle, high-pressure water is pressed into the grouting pipe continuously before the pile cap enters sludge so that the sludge can be prevented from entering an grouting area, and the grouting pipe is filled with water stop materials immediately after the pile cap is in place.
Description
Technical field
The present invention relates to a kind of bridge prefabrication cushion cap preformed hole and pile foundation junction water stop construction method.
Technical background
The construction of bridge spanning the sea has at present entered the batch production production phase, and the sealing problem of prefabricated cushion cap preformed hole and pile foundation joining place not yet effectively solves, and has hindered the process of bridge girder plant.
Summary of the invention
The sealing problem being connected with pile foundation for solving prefabricated cushion cap preformed hole, the invention provides a kind of bridge prefabrication cushion cap preformed hole and pile foundation junction water stop construction method.
The technical solution adopted for the present invention to solve the technical problems is, in prefabricated cushion cap preformed hole, establish upper and lower two interval, road 40cm left and right with the loose flange circle of watertight rubber band, middle built-in slip casting pipe and outlet pipe, before cushion cap enters mud, in Grouting Pipe, do not stop to be pressed into water under high pressure, to prevent that mud from entering slip casting district, after cushion cap is in place, in Grouting Pipe, inject immediately sealing material (band fibrous cement paste).
The invention has the beneficial effects as follows, reliable construction quality, stagnant water effect is good.
Accompanying drawing explanation
Fig. 1 is prefabricated cushion cap preformed hole and pile foundation junction water stop construction method plan view
Fig. 2 is prefabricated cushion cap preformed hole and pile foundation junction water stop construction method sectional drawing
In figure: 1. prefabricated reinforced concrete cushion cap; 2. two after date pouring concretes; 3. pile foundation; 4. descend antipriming; 5. go up antipriming; 6. Grouting Pipe; 7. outlet pipe; 8. slip casting district.
Specific implementation method
In Fig. 2, lower antipriming (4), upper antipriming (5) are fixed on cage of reinforcement when prefabricated reinforced concrete cushion cap (1) is prefabricated, Grouting Pipe (6) outlet pipe (7) is installed simultaneously, build prefabricated reinforced concrete cushion cap (1), prefabricated reinforced concrete cushion cap (1) is arranged in pile foundation (3), then in Grouting Pipe (6), waterproofing materials (band fibrous cement paste) is injected to slip casting district (8) till outlet pipe (7) pulp.
Claims (1)
1. prefabricated cushion cap preformed hole and a pile foundation junction water stop construction method, is characterized in that: in prefabricated cushion cap preformed hole, establish upper and lower two road antiprimings, establish Grouting Pipe and inject sealing material between Er road antipriming.
