Description
Technical Field
The application belongs to the technical field of constructional engineering, and particularly relates to an anti-seepage treatment method for a basement bottom plate construction joint.
Background
The construction joint refers to a joint formed between the concrete which is poured in advance and then due to the design requirement or the requirement of segmental pouring in the concrete pouring process. The construction joint is not a real existing joint, and only because the initial setting time of the first poured concrete is longer than the initial setting time or the type of the first poured concrete is different from that of the later poured concrete, a joint surface exists between the first poured concrete and the later poured concrete, and the joint surface is called as the construction joint.
According to relevant regulations of basement construction of buildings in China, construction joints are not allowed to be left in the construction of basement floors, and corresponding measures must be taken during construction to ensure that concrete of the basement floors of the buildings is continuously poured. However, in actual construction, due to construction power failure, failure of a concrete delivery pump and the like, a construction joint is formed because continuous pouring cannot be performed during concrete pouring. And the horizontal member and the vertical member in the basement can not be poured at one time due to the construction requirements of the basement of some buildings. Therefore, construction joints inevitably occur when the basement bottom plate is actually constructed.
The basement of the building is affected by self reasons and external environment, and the basement terrace is easy to damp due to the existence of the bottom plate construction joint, so that the water seepage condition is caused. The seepage problem is handled to construction joint present tradition adoption stagnant water steel sheet, increases behind the stagnant water steel sheet, meets during the gap infiltration of stagnant water steel sheet and can't ooze inwards again when water connects the gap at stubble position along new and old concrete, and the stagnant water steel sheet has played the effect of cutting off water infiltration route. Meanwhile, when water permeates along the gap between the water stop steel plate and the concrete, the water stop steel plate has a certain length, so that the permeation path of the water is also prolonged, and the waterproof effect can be achieved. However, for a construction joint or a construction cold joint in which a water-stop steel plate cannot be set due to the limitation of construction conditions or not, the conventional method is to simply clean the leakage surface and coat cement paste for treatment, and the method cannot fundamentally solve the problem of internal water seepage.
