Embodiment 1

[0035] Such as figure 1 or image 3 As shown in the present invention, a water conservancy project cross-joint post-installation built-in water-stop assembly structure and construction method, the construction plan and working principle are as follows: the depth of the construction joint 5 is determined before construction, and then two symmetrical openings are opened on both sides of the construction joint 5. The grouting hole 1 whose depth is greater than the depth of the construction joint 5; then set up the wire saw above the grouting hole 1, and the cutting part of the wire saw 4 can reach the bottom of the construction joint 5 through the grouting hole 1 after erection. In the present invention, the wire saw 4 Select a concrete cutting wire saw with a beaded diameter of 8mm-11mm; set up the wire saw 4 and carry out the construction of the cutting groove 2, and open a cutting groove 2 with a width greater than the width of the waterstop 3 and the depth of the cutting groo...

Embodiment 2

[0037] Such as Figure 1-Figure 3 As shown, a water conservancy project cross-joint post-installation built-in water-stop assembly structure, the structure includes a grouting hole 1, a groove 2, and a water-stop strip 3, and the two grouting holes 1 are set on both sides of the construction joint 5, and Symmetrical about the construction joint 5;

[0038] The cut groove 2 is set perpendicular to the construction joint 5, and the two ends are respectively connected with a grouting hole 1, and the depth of the grouting hole 1 is greater than the depth of the construction joint 5;

[0039] After the two grouting holes 1 and the cutting grooves 2 are connected, a section is formed in the concrete structure 6, and the section is located below the construction joint 5;

[0040] The waterstop 3 is installed in the section. The diameter of the grouting hole 1 is 120-150 mm.

[0041] The cutting depth of the groove 2 is greater than the depth of the construction joint 5 .

Abstract

The invention discloses a construction method for installing a built-in water-stop assembly structure after crossing a joint in a water conservancy project. The steps are as follows: step 1: opening grouting holes on both sides of the construction joint; step 2: erecting a wire saw according to the position of the grouting hole; Step 3: Use a wire saw to cut grooves at the construction joints; Step 4: Remove the wire saw and clean the section; Step 5: Install the waterstop in the section and fix the waterstop; Step 6: Backfill and pour; Step 7: Waterproof treatment of construction joints. A built-in water-stop assembly structure for water conservancy projects spanning joints, including grouting holes, cut grooves, and waterstops. Two grouting holes are symmetrically opened on both sides of the construction joint; Grouting holes; grouting holes and grooves form a dumbbell-shaped section; waterstops are installed in the section. The invention provides a post-mounted waterstop structure and a construction scheme to effectively solve the joint waterstop work that cannot be handled in the construction stage, and the construction scheme is simple and the construction means are easy to realize.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a water conservancy project spanning joints and a built-in water-stop assembly structure and a construction method. Background technique [0002] Many civil structures involved in water conservancy projects require a certain anti-seepage function. During the construction process, due to construction reasons, structural reasons, geological reasons and other external forces, the anti-seepage structure is often divided into several small pieces. Construction joints, deformation joints, structural joints or cracks will be formed between small blocks, and these joints will form leakage channels, which will make the structure that has anti-seepage function lose its anti-seepage effect. In order to block the leakage channels of construction joints, deformation joints, structural joints or cracks, these joints must be treated, that is, water-stop strips or other wat...
