Embodiment

[0054] This embodiment provides a curtain grouting method. The working conditions of applying the method are basement concrete side walls, the concrete thickness is 50cm, and there is a small amount of water inflow. The method includes the following steps:

[0055] S1: Adjust and determine the gel time of the acrylate slurry to be 28-32 sec by adjusting the amount of initiator and cross-linking agent added in the acrylate slurry.

[0056] S2: Use an impact drill to drill holes on the backwater surface of the concrete wall to a depth of 48-49cm, use a steel bar with a diameter of 10mm to penetrate the inside of the drill hole, and hit the steel bar with a hammer to the depth of the undrilled hole. The concrete wall of 1-2 cm produces cracks; the drill holes are multiple, and the hole spacing between each drill hole is 1.5m, and the points are arranged in a plum blossom shape, and the drill bit of the impact drill is 16mm in diameter and 600mm in length.

[0057] S3: Place a PVC...

Abstract

The invention belongs to the technical field of grouting and plugging, and discloses a curtain grouting method. The method includes the following steps: determining the gel time of the acrylate grouting solution; drilling holes on the backwater surface of the concrete wall to a depth of the thickness of the concrete wall minus 1-2 cm, and destroying the undrilled 1-2 cm The concrete wall is cracked; the drill holes are multiple; the PVC line pipe is placed in the drill hole, one end of the PVC line pipe is in contact with the crack, and the other end of the PVC line pipe is connected with the injection hole. One end of the grouting needle is connected; the other end of the grouting needle is connected to the grouting equipment for grouting. The invention solves the problems of acrylate grouting solution gel time and grouting effect during curtain grouting. The problem of large material consumption caused when the acrylate grouting liquid enters the concrete is avoided, and the construction environment is improved.

Description

technical field [0001] The invention belongs to the technical field of grouting and plugging, and in particular relates to a curtain grouting method. Background technique [0002] Curtain grouting is a commonly used grouting method for concrete maintenance. It is characterized in that a new plastic waterproof layer is formed on the water-facing surface of the concrete. The process implementation is to drill through the concrete wall, and install the grouting needle directly in the hole. The material to be poured is commonly acrylated grout. The pouring equipment is a two-liquid grouting machine. [0003] Acrylate grout generally has three components when it leaves the factory: A component, B component and C component, of which A component is the resin part, and B component and C component are initiator and crosslinking agent respectively. In the process of grouting, it is also necessary to add water. Add the C component into the resin liquid, add the B component into th...
