Embodiment 1

[0062] This example is aimed at the roof leakage treatment project of Chongqing Construction Engineering Group Industrial Building. After on-site inspection, it is found that the roof of the Construction Engineering Group Industrial Building has serious water seepage. The main reasons are: 1) water seepage from cracks caused by the failure of the original waterproof layer; 2) original waterproofing 3) Improper construction of the roof drainage ditch waterproof house leads to damage to the waterproof layer, which affects the integrity of the waterproofing; 4) Leakage caused by material aging.

[0063] Since the building is a fixed office space, the construction period is tight and the construction requirements are strict. In order to speed up the construction progress, shorten the construction period, reduce environmental pollution, and be conducive to environmental protection, the original waterproof layer should be repaired as soon as possible. The construction method of rebui...

Embodiment 2

[0065] This embodiment is aimed at the water seepage control project of Huayan Tunnel. During the construction process of the third bid project of Huayan Tunnel in Chongqing, there were fault cracks in the tunnel, which caused many drips and water leakage in the tunnel, which seriously affected the use function, construction safety and construction of the tunnel. schedule. In order to ensure that the construction can be carried out normally and safely, it is necessary to remediate the fault cracks in the tunnel. In order to restore the integrity of the concrete block without destroying the performance of the waterproof layer of the original structure, and to meet the requirements of strength and impermeability, considering that there may be water in the cracks, the grouting material is required to be solidified in the presence of water. , and has a certain strength. According to the above principles, the construction method used for grouting reconstruction and repair of the ex...

Abstract

The invention discloses a construction method for grouting reconstruction repairing of an existing waterproof layer. By referring to related engineering data, the position of the waterproof layer andthe scope to be repaired of a building are determined, and then setting out, hole arrangement and grouting are performed. A traditional reconstruction method is changed, the construction waste disposal and roofing repairing processes are reduced, grouting holes are arranged in a plum-blossom shape to enable the effective coverage area to be larger, and the cost is saved. Accumulated water betweenthe holes is discharged through the pressure difference between the holes which is formed by row-by-row and hole-by-hole grouting, the discharged water is replaced and supplemented by grout, and a small amount of undischarged water participates in the solidification reaction of the grout, so that the accumulated water of an outer layer of the waterproof layer is completely eliminated, and a new waterproof layer is formed; and the grout replacing the accumulated water solidifies and condenses into a waterproof body in cracks or holes in the waterproof layer, a liquid state of the grout is changes into a solid state, the water storage state above the waterproof layer is completely changed, a permanent overall waterproof layer is formed, and the repair of original leakage points is completed,so that the long-term effect of leakage control is ensured.

Description

technical field [0001] The present application relates to the field of building waterproofing, in particular to a construction method for grouting reconstruction and repair of an existing waterproof layer. Background technique [0002] With the progress of society and the continuous improvement of material and spiritual civilization, my country's construction industry has achieved good development. At the same time, due to reasons such as design, construction and use, some existing buildings are prone to leakage of waterproof layers. It not only affects the use function of the building, but also affects the durability of the building, and may further affect the safe use of the building. [0003] Therefore, it is urgent to repair the leaking waterproof layer no matter from the function of use or the safety and durability of the building. The current repair process is mainly through renovation and redoing, partial repair or adding an additional waterproof layer. These traditio...
