Embodiment 1

[0035]Such asfigure 1 orimage 3 As shown, the construction method, construction method, construction scheme and working principle of the water conservancy engineering span rear rear rear, the construction scheme is determined before the construction, then determine the depth of the construction seam 5, then open two sides of the construction seam 5 The depth of the road is greater than the grouting hole of the depth of the construction seam 1; then set the rope saw above the grout hole 1, and the rear rope saw 4 cutting portion can be adjusted below the construction seam 5 below, the rope saw in the present invention 4 Use a concrete cutting rope saw of the beaded diameter of 8 mm to 11 mm; after the rope saw 4, the construction of the slot 2 is performed, and the width is larger than the slot 2 of the water tape 3 width and the depth of the groove 2 is larger than the construction seam 5. Depth; After the tank 2 is completed, it is necessary to clean the cutting groove 2 and the gr...

Embodiment 2

[0037]Such asFigure 1 - Figure 3As shown, a water conservancy engineering span rear mounting structure includes a grouting hole 1, a slit 2, a water tape 3, and two of the grouting holes 1 are opened on both sides of the construction seam 5, and About the construction seam 5 symmetry;

[0038]The slot 2 is opened perpendicular to the construction seam 5, and the two ends are connected to a grouting hole 1, and the depth of the grouting hole 1 is greater than the depth of the construction seam 5;

[0039]After the two, the grouting holes 1 and the slot 2 are connected to the concrete structural 6, which is located below the construction seam 5;

[0040]The tape 3 is mounted in a section. The grouting hole 1 has a pore diameter of 120 to 150 mm.

[0041]The cutting depth is greater than the depth of the construction seam 5.

[0042]The two ends of the water belt 3 are provided with a angle and the middle section is a wave shape; the size of the soil strip 3 is adapted to the size of the section, and...

Abstract

The invention discloses a construction method of a water conservancy project joint-crossing post-installation built-in water stop assembly structure. The construction method comprises the following steps that step 1, grouting holes are formed in the two sides of a construction joint; step 2, a rope saw is erected according to the positions of the grouting holes; step 3, a cutting groove is formed in the construction joint through the rope saw; step 4, the rope saw is dismantled, and the fracture surface is cleaned; step 5, a water-stop belt is installed in the fracture surface, and the water-stop belt is fixed; step 6, backfilling and pouring are carried out; and step 7, waterproof treatment is carried out on the construction joint. The water conservancy project joint-crossing post-installation built-in water stop assembly structure comprises the grouting holes, the cutting groove and the water stop belt, and the two grouting holes are symmetrically formed in the two sides of the construction joint; the grouting holes are correspondingly formed in the two ends, perpendicular to the construction joint, of the cutting groove; the grouting holes and the cutting groove form dumbbell-shaped sections; and the water stop belt is installed in the fracture surface. According to the water conservancy project joint-crossing post-installation built-in water stop assembly structure and the construction scheme, the problem that joint water stop work cannot be treated in the construction stage is effectively solved, the construction scheme is simple, and the construction means are easy to achieve.

Description

Technical field[0001]The present invention relates to the field of water conservancy engineering, and in particular to a hydraulic engineering and construction method and construction method.Background technique[0002]Water conservancy projects involve many civil construction requirements require a certain anti-seepage function, in the process of construction, due to construction, structural reasons, the role of the geology, often divide the anti-seepage structure into several small pieces The body, the small pieces and the small pieces will form construction seams, deformation seams, structural seams or cracks. These sections form a leakage channel, which makes the structural body with anti-seepage function. To block the leakage channel of the construction seam, deformed seam, structural seam or crack, these seams must be treated, that is, mounting the water strip or other water water material in the slit surface.[0003]Sewing surfaces in the construction stage can simultaneously ins...
