Abstract
The invention discloses a water-stopping method for new and old concrete construction joints. The water-stopping method for the new and old concrete construction joints comprises the following steps: 1, according to design requirements of newly-poured concrete, determining a water-stopping position in the newly-poured concrete, wherein the water-stopping position in the newly-poured concrete is 20-50 cm below the surface of the newly-poured concrete, and accordingly determining a water-stopping position in old concrete; 2, clearing up the surface of the old concrete corresponding to the water-stopping position in the newly-poured concrete to ensure that the surface of the old concrete is clean and smooth, brushing a bonding agent to adhere a polyethylene pore-closed board to the surface of the old concrete; 3, adhering an L-shaped water-stopping vertical side to the surface of the polyethylene pore-closed board, pressing the top of the L-shaped water-stopping vertical side by using a galvanized steel sheet, and fixing the L-shaped water-stopping vertical side on the surface of the old concrete by using galvanized expansion bolts; and 4, pouring the new concrete according to a conventional construction method. The water-stopping method for the new and old concrete construction joints has the advantages of convenience in construction and reliable water-stopping effect, avoids notching the old concrete and reduces destruction of the old concrete.
Description
Technical field
The present invention relates to the water-stopping method of concrete construction joint, especially relate to water-stopping method new, the old concrete constuction joint.
Background technology
In hydraulic engineering, concrete-lined structure is subjected to variations in temperature and concrete shrinkage to do the time spent, usually needs to arrange the shrinkage joint, bears the structure of hydraulic pressure, and the seam planted agent arranges sealing, each side Transducers Embedded in Concrete 20-25cm of sealing.In the practice of construction process, because leakage is buried or other reasons causes first pouring concrete (old concrete) when not imbedding sealing, need a kind of new water-stopping structure of research to solve sealing problem between New-old concrete.
Summary of the invention
The object of the invention is to provide a kind of water-stopping method of new, old concrete constuction joint.
For achieving the above object, the present invention takes following technical proposals:
The water-stopping method of new, old concrete constuction joint of the present invention comprises the steps:
The first step, according to the designing requirement of newly placed concrete, determine the sealing position in the newly placed concrete, the sealing position in the described newly placed concrete is at newly placed concrete lower face 20-50cm place, determines accordingly the position of old concrete sealing;
Second step, newly placed concrete is ended water level put corresponding old concrete surface and clear up, guarantee the old concrete surface clean, smooth after, brushwork adhesive is bonded at the old concrete surface with polyethylene closed pore plate;
The 3rd step, that stile that will " L " shape sealing is affixed on polyethylene closed pore plate is surperficial, and pushes down the stile top of described " L " shape sealing with galvanized steel plain sheet, is fixed on the old concrete surface with zinc-plated expansion bolt;
The 4th the step, build as placed concrete according to the job practices of routine.
The invention has the advantages that easy construction, stagnant water effect are reliable, avoided old concrete is slotted, reduced the destruction to old concrete.
Description of drawings
Fig. 1 is that the present invention is new, the water-stopping structure schematic diagram of old concrete constuction joint.
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
The specific embodiment
As shown in Figure 1, 2, of the present invention
Newly, the water-stopping method of old concrete constuction joint, comprise the steps:
The first step, according to the designing requirement of newly placed concrete 1, determine the sealing position in the newly placed concrete 1; Sealing position in the described newly placed concrete 1 is the 20-50cm place below newly placed concrete 1 surface 2, determines accordingly the sealing position of old concrete 3;
Second step, newly placed concrete 1 is ended water level put corresponding old concrete 3 surfaces and clear up, guarantee old concrete 3 surface clean, smooth after, brushwork adhesive is bonded at old concrete 3 surfaces with polyethylene closed pore plate 4;
The 3rd step, the stile of " L " shape sealing 5 is affixed on polyethylene closed pore plate 4 surfaces, and pushes down the stile top of described " L " shape sealing 5 with the galvanized steel plain sheet 6 of wide 10cm, thick 1cm, be fixed on old concrete 3 surfaces with zinc-plated expansion bolt 7; The model of zinc-plated expansion bolt 7 is M100 * 10, the spacing 30-40cm between the adjacent zinc-plated expansion bolt 7;
The 4th the step, build as placed concrete according to the job practices of routine.
