Problems solved by technology

[0002] At present, the existing technology commonly used in the industry is as follows: foundation floor leakage is a common quality problem in engineering, due to the nature of concrete itself and unavoidable problems in construction, foundation floor leakage is difficult to prevent - the foundation floor construction process, Due to the influence of the vertical reinforcement of the structure, it is impossible to bury the water-stop steel plate. Usually, water-swelling water-stop strips are buried at the construction joints. However, during the construction, cracks are generated due to insufficient cleaning of the concrete surface or insufficient vibration during the pouring process, as well as shrinkage and creep of the concrete. , will cause the foundation floor to leak
If the project has not been delivered for use, passive measures can be used for waterproofing construction, and waterproofing agent can be applied on the outer surface of the joints for plugging, but the plugging effect is generally not obvious
Drilling and grouting can also be used to seal the leaking part, but since there is no horizontal channel, the grout cannot flow well along the horizontal direction, the plugging effect will not be obvious, and the grout will be wasted, and at the same time, it will generate a lot of cost expenditure
[0003] In summary, the problems existing in the prior art are: due to the nature of the concrete itself and unavoidable problems in construction, it is difficult to prevent the leakage of the foundation floor; there is no horizontal channel, the grout cannot flow well along the horizontal direction, and the plugging The effect will not be obvious, and it will cause waste of slurry, and will generate a lot of expenses at the same time
[0004] The difficulty and significance of solving the above technical problems: Adding expansion agent to concrete can reduce the cracks caused by concrete shrinkage and creep, but the influence of human factors in the construction process causes leakage of the foundation floor

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] Due to the nature of concrete itself and unavoidable problems in construction, foundation slab leakage is difficult to prevent. The materials of the invention are all plastic materials, which are relatively light and easy to fix, and the construction is carried out before the steel bars are bound, which does not affect the normal construction period at all.

[0025] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the anti-seepage construction method of the foundation floor provided by the embodime...

Abstract

The invention belongs to the technical field of building construction, and discloses an anti-leakage construction method for a foundation bottom plate, and a building construction platform; before thebottom plate is poured, a horizontal grouting pipe is pre-embedded in a joint part of the bottom plate and an exterior wall, and then a vertical grouting mouth is left and placed on the upper portionof the foundation bottom plate; and leakage occurs on the bottom plate, grouting is performed on the inside of a reserved grouting mouth of a leakage part, after grout reaches the inside of the horizontal grouting pipe, the grout is grouted into a gap between the bottom plate and the exterior wall for plugging. After the grouting is completed, before cement slurry in the grouting pipe is hardened, a plug is opened with clean water, so that when the leakage occurs again in a later stage, the grouting can be performed again to achieve a purpose of repeated usage. Materials of the method and theplatform are plastic materials, are light and easy to fix, construction is performed before a reinforcing steel bar is bound, and a normal construction period is not completely affected; and the grouting pipe is simple in structure and low in cost, and economic benefit is good compared with other grouting leaking stoppage manners. If the leakage occurs on the bottom plate, the method performs targeted grouting and leaking stoppage, and is good in plugging effect.
