Break pile crown waterstop inner ring into two with one's hands, inject epobond epoxyn, the wing of pile crown waterstop is bonded on the pile crown outer wall, another wing of pile crown waterstop is bonded on the bed course of base plate;
The base plate waterproof roll of mating formation on the bed course of base plate is with another wing welding of this pile crown waterstop or bond on the base plate waterproof roll.
Waterproof method of the present invention, one wing of pile crown waterstop is bonded on the pile crown outer wall, another wing of pile crown waterstop is bonded on the bed course of base plate, and with another wing welding of this pile crown waterstop or bond on the base plate waterproof roll of mating formation on the bed course, thereby waterproofing course and the seamless link of base plate waterproof roll with pile crown, prevent that underground water from entering into the surface of basement bottom board by the constuction joint between bed course and pile crown outer wall, improved the waterproof reliability.
Description of drawings
Fig. 1 is the pile crown cross section structure schematic diagram behind the employing waterproof method of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiments of the invention are done a detailed elaboration.
Preformed pile generally comprises steel pipe pile and precast reinforced concrete pile, as shown in Figure 1 be steel pipe pile, pile crown outer wall 1 is a steel pipe; For precast reinforced concrete pile, its outer wall is a concrete.
Waterproof method of the present invention, as shown in Figure 1 be the pile crown cross section structure figure of steel pipe pile, comprise step:
Pile crown waterstop 4 is packed into pile crown; Pile crown waterstop 4 is columniform sleeve pipe, can pack into pile crown, and the pile crown periphery generally is cylindrical, inner concreting 9 and connecting reinforcement 6;
Break pile crown waterstop 4 inner rings into two with one's hands, inject epobond epoxyn 5, the wing of pile crown waterstop 4 is bonded on the pile crown outer wall 1, another wing of pile crown waterstop 4 is bonded on the bed course 2 of base plate; When injecting epobond epoxyn 5, epobond epoxyn 5 is continuous at necessary 360 degree of pile crown waterstop 4 inner rings, and can roll pile crown waterstop 4 inner rings with the hand roller, and epobond epoxyn 5 is evenly distributed, and can carry out next procedure in common 24 hours; Bed course 2 is positioned at around the pile crown outer wall 1, can be the concrete of building;
The base plate waterproof roll 3 of mating formation on the bed course 2 of base plate with another wing welding of this pile crown waterstop 4 or bond on the base plate waterproof roll 3, is about to bond to the wing welding of the pile crown waterstop 4 on the bed course 2 or bonds on the base plate waterproof roll 3.When mating formation base plate waterproof roll 3, bed course 2 and base plate waterproof roll 3 can clean down, with adhesive base plate waterproof roll 3 are bonded on the bed course 2; Can select the pile crown waterstop 4 of corresponding material in addition at the material of different base plate waterproof rolls 3, to improve the adhesive strength of pile crown waterstop 4 and base plate waterproof roll 3.
This shows that waterproof method of the present invention with the waterproofing course and the seamless link of base plate waterproof roll of pile crown, prevents that underground water from entering into the surface of basement bottom board by the constuction joint between bed course and pile crown outer wall, improved the waterproof reliability.
In a preferred embodiment,, before pile crown waterstop 4 is packed into pile crown, also comprise step in order to improve the adhesive strength of pile crown waterstop 4 and pile crown outer wall 1: clean pile crown waterstop 4 inner rings, and the bonding position on the cleaning pile crown outer wall 1.Specifically can be stained with cleaning agent and be coated with pile crown waterstop inner ring, and towel off dried immediately with hairbrush; Greasy dirt or iron rust are generally arranged on the pile crown outer wall 1, can improve adhesive strength under the cleaning.
If preformed pile is precast reinforced concrete pile, also can a little ground water seepage at the pile crown top, for this reason in a preferred embodiment, waterproof method of the present invention also comprises step: at pile crown top brushing cement-base infiltration crystallization water-repellent paint 8 or the dried penetrant crystalline powder 8 that spreads, be penetrated into base plate with the underground water that prevents pressure by the pile crown top.
Pile crown top brushing cement-base infiltration crystallization water-repellent paint or dried spread the penetrant crystalline powder after, can also comprise step: the connecting reinforcement 6 root injection water-swellable glue 7 between pile crown and cushion cap.Can prevent that underground water is penetrated into base plate by connecting reinforcement 6.
In a preferred embodiment; for base plate waterproof roll and pile crown waterstop are protected; after another wing with this pile crown waterstop welds or bonds on the base plate waterproof roll; also comprise step: the outer ring at base plate waterproof roll 3 tops and pile crown waterstop 4 is provided with topping 10, and this topping can be the pea gravel concreten of building.
Be the concrete application of waterproof method of the present invention in steel pipe pile below:
