A water level pressure grouting sealing method

Abstract

The invention discloses a water level pressure grouting sealing method, which belongs to the field of basement water leakage sealing. It adopts artificial creation of conditions suitable for closed pouring double-fast cement. The water level pressure reduces the water gushing pressure, creates conditions for concrete hardening, and artificially raises For the indoor water level, use the water pressure to reversely press the double-quick mortar into the leak to achieve the plugging effect; the invention has the characteristics of convenient material collection, simple installation, quick response, and flexibility, which can effectively save costs and ensure continuous construction of the basement.

Description

technical field

[0001] The invention belongs to the field of water leakage sealing in basements, and in particular relates to a water level pressure grouting sealing method. Background technique

[0002] Water seepage from springs in the basement is a sudden engineering quality problem during the construction process, which not only has an adverse effect on the construction of subsequent processes, but also poses a huge safety hazard to the overall construction quality of the project;

[0003] In the traditional construction process, for the case of large springs or high water pressure, methods such as opening drainage, outdoor precipitation, and pressure pumping are usually used, which require professional equipment and corresponding materials, and have high requirements for construction personnel. Equipment costs, High material cost and labor cost;

[0004] There are following problems in prior art:

[0005] (1) There are many construction procedures and the process is c...

Examples

Embodiment 1

[0058] Such as Figure 1 to Figure 6 Shown: a water level pressure grouting plugging method, including a water leakage port 6, a cylinder 1, a cylinder 2 2 and a plugging piece 4, the diameter of the cylinder 1 is smaller than the diameter of the cylinder 2,

[0059] Also includes the following steps:

[0060] Step 1: Cut out the regular water leak 6, including:

[0061]1) Determine the water leak 6 of the bottom plate 5 to be blocked, excavate the concrete until the steel bars on the surface of the bottom plate 5 are exposed, and expand to a circular shallow pit 3 that is larger than the diameter of the cylinder 2 around the water leak 6;

[0062] 2) Control the bottom of the circular shallow pit 3 to be stepped, the circular shallow pit 3 includes a first stepped hole and a second stepped hole, the first stepped hole is located on the second stepped hole, and the diameter of the first stepped hole is larger than that of the cylinder two 2, the diameter of the second steppe...
