Description
Technical Field
The invention relates to the technical field of constructional engineering, in particular to an anti-seepage soil post-cast strip and a construction method thereof.
Background
The post-cast strip is a concrete strip which is reserved in structures such as beams, plates (including foundation slabs) and walls and has a certain width and is poured after a certain time in order to adapt to the influences of factors such as environmental temperature change, concrete shrinkage and uneven settlement of the structure.
At present, domestic high-rise, super high-rise and large-volume projects are more and more, the volume of the projects and the height of structures are continuously increased, the construction period is prolonged, the height difference between building structures is obviously increased, and in order to prevent main cracks caused by uneven settlement of the buildings, post-pouring belts are arranged among large positions of the height difference of the building structures in most of the projects. For example, post-cast strips are reserved between the garage and the main building and between the skirt building and the main building. Generally, the concrete of the post-cast strip is poured after the main body structure is finished and the settlement is basically stable.
The basement outer wall post-cast strip is the last process of the basement structural engineering construction, and the completion time of the basement outer wall post-cast strip is directly related to the earth backfill and precipitation time of the whole basement. How to reduce the construction time of the basement outer wall post-cast strip and improve the construction quality of the basement outer wall post-cast strip becomes a key node in the whole basement structure construction process.
When the basement engineering is located below the ground water level, the traditional post-pouring belt is adopted, and the sealing can be carried out only after the deformation is stable, so that the sealing time of the post-pouring belt of the basement outer wall is prolonged, the basement earthwork is backfilled after the sealing time is prolonged, the precipitation time and the foundation pit exposure time are increased, and the engineering cost is increased and the safety risk is increased.
The existing solution is to adopt an expansion reinforcing band, which is a technical measure of reducing or eliminating a post-cast band and an expansion joint and prolonging the continuous casting length of a member by casting compensation shrinkage concrete at a post-cast band part preset in a structure and can be divided into a continuous type, an intermittent type and a post-cast type. The continuous expansion reinforcing band is formed by pouring concrete at the expansion reinforcing band part and concrete adjacent to two sides of the expansion reinforcing band part at the same time. The continuous expansion reinforcing band is commonly used in the process of floor slab casting, and the rough procedures are firstly casting concrete of the floor slabs on two sides of the expansion reinforcing band and then casting the expansion reinforcing band by using high-grade concrete. However when pouring floor slab concrete, the difficult region that restricts concrete lateral inflow reinforcing band leads to reinforcing band downside concrete to miss the designing requirement, influences its quality of pouring, as shown in fig. 2 and fig. 3, be reinforcing band region 10 between first floor slab 8 and the second floor slab 9, when floor slab pours, can be at reinforcing band region 10 regional inflow floor slab concreting 11. And when pouring the terrace plate that thickness is lower than normal, still have the condition of similar above-mentioned influence quality, when being applied to the wall with the inflation strengthening band now and pouring, this problem will be more serious, and in the strengthening band between two walls, need pre-buried a large amount of reinforcing bars, has restricted the possibility of directly addding the side template in strengthening band both sides.
