In general, a brick-concrete structure is a structure that a small part of reinforced concrete and a large part of brick wall bear load, and is also called a reinforced concrete mixed structure. Because the brick is the minimum standardized component, has low requirements on construction sites and construction technology, can be built into wall bodies with various shapes, and can be produced in various places. It has good durability, chemical stability and atmospheric stability. Can save cement, steel and wood, does not need a template, and has lower manufacturing cost. The construction process and the construction equipment are simple. The brick has better sound insulation and heat preservation and heat insulation performance than concrete and other wall materials, so the brick-concrete structure is a structural form widely adopted in the construction of low-rise residences. However, as time goes on, the buildings with the brick-concrete structure have more quality problems, and the problems of rain leakage on the roof, water leakage on the wall surface and in the toilet generally exist, so that the attractiveness is influenced, and the safety of the buildings is possibly endangered.
Therefore, when the brick-concrete masonry structure leaks, the brick-concrete masonry structure needs to be processed in time, and the leakage is prevented from further expanding and developing. The upstream face is the position that the seepage took place, and the surface of a poor water is the outside that takes place the position at the seepage because the seepage generally takes place in the inside of brick-concrete masonry structure, and under the condition of not destroying original brick-concrete masonry structure, constructor can only handle at the surface of a poor water (the outside of brick-concrete masonry structure). However, the problem of leakage is not fundamentally solved only by carrying out rigid waterproof layer treatment from the back water surface, and the masonry structure is still soaked in water for a long time, so that the hidden danger of secondary leakage exists.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the term "comprises/comprising" and any variations thereof in the description and claims of the present invention and the above-described drawings is intended to cover non-exclusive inclusions, such that a process, method, apparatus, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1, the water stopping structure for water leakage repair of a brick-concrete masonry structure includes: a backfill layer 1, a waterproof layer 2 and an impervious blocking layer 3;
the backfill layer carries out grouting, filling and compaction on the outer backfill layer of the brick-concrete masonry structure through high-strength impervious grouting materials, the waterproof layer is solidified and reconstructed through grouting on the upstream face of the brick-concrete masonry structure, and the impervious blocking layer carries out integral blocking on the backside face of the brick-concrete masonry structure.
The backfill layer of the invention carries out grouting, filling and tamping on the outer backfill layer of the brick-concrete masonry structure through the high-strength impervious grouting material, and can reduce the probability of direct contact between the brick-concrete masonry structure and a peripheral water source; the waterproof layer is solidified and reconstructed on the upstream face of the brick-concrete masonry structure through grouting, so that a leakage channel in the brick-concrete masonry structure can be plugged; the impervious blocking layer blocks the back water surface of the brick-concrete masonry structure integrally, and can supplement a backfill layer and a waterproof layer to avoid leakage hidden danger; therefore, the leakage problem can be fundamentally solved, and the danger of secondary leakage caused by the fact that the brick-concrete masonry structure is soaked in water is avoided.
Preferably, as shown in fig. 2, the backfill layer is formed by forming a first grouting hole 11 in an outer backfill layer of the brick-concrete masonry structure, burying a grouting pipe in the grouting hole, injecting the prepared high-strength impervious grouting material, removing the grouting pipe, and blocking the grouting hole.
Preferably, as shown in fig. 2, the waterproof layer is formed by forming a second grouting hole 21 on the upstream side of the brick-concrete masonry structure, burying a grouting needle in the grouting hole, injecting the prepared acrylate grouting material, removing the grouting needle, and blocking the grouting hole.
Preferably, the impervious blocking layer blocks the back water surface of the brick-concrete masonry structure integrally through a back water paint.
In the case of visible water leakage from cracks or masonry mortar joints, the following may be the reasons: (1) no waterproof layer is arranged outside; (2) the peripheral waterproof layer is invalid; (3) the masonry mortar is not full; (4) the masonry has cracks; (5) the density of the backfill soil layer is insufficient. For these reasons, the following construction method is adopted.
And under the condition that open water leakage can be seen in cracks or mortar joints of the masonry, the waterproof layer is solidified and reconstructed by grouting on the upstream surface of the brick-concrete masonry structure, and the impervious blocking layer is used for integrally blocking the back water surface of the brick-concrete masonry structure.

Further, in the case that the open water leakage is observed in a large area of the wall surface, as shown in fig. 4, the structure and soil property of the brick-concrete masonry structure are first investigated.
In the case of visible open water leakage over a large area of the wall surface, the following reasons may be considered: (1) no waterproof layer is arranged outside; (2) the failure of the peripheral waterproof layer; (3) the masonry mortar is not full; (4) the masonry has cracks; (5) gaps exist in the backfill soil layer.

In the case of wall moisture regain and salt evolution, the following reasons may be considered: the positions of the bottom plate and the side wall structures are not provided with damp-proof and waterproof barriers in advance, and water vapor rises through capillary pores of the wall bearing foundation structure to cause the wall to be damp and sand ash and decorative surface to be alkali-resistant and bulge. For these reasons, the following construction method is adopted.
Under the condition that the wall body is damp and salt is separated, as shown in figure 5, the waterproof layer is solidified and reconstructed by grouting on the upstream face of the brick-concrete masonry structure, and the impervious blocking layer is used for integrally blocking the back water face of the brick-concrete masonry structure.
