Description

Basement post-pouring belt system and preparation method thereof Technical Field The invention relates to the technical field of basement post-cast strips, in particular to a basement post-cast strip system and a preparation method thereof. Background The concrete can generate volume shrinkage (plastic shrinkage, dry shrinkage and carbonization shrinkage) in the hydration hardening process, the environmental temperature change can lead to thermal expansion and contraction of the concrete, the basement structure is huge (large-volume concrete), shrinkage and temperature deformation are easy to generate tensile stress inside, meanwhile, the basement is below the groundwater level (or groundwater influence area), waterproofing is a core function requirement, joints and construction joints of the concrete structure are natural waterproof weak points, if improper treatment is easy to become a water seepage channel, cracks after large-volume concrete pouring further aggravate the risk of waterproof failure, simple treatment (such as pre-buried water stopping sheets) of the traditional construction joints cannot meet the requirement of the basement with high waterproof grade, and along with the progress of concrete material technology (such as compensation shrinkage concrete research and development) and structural mechanics analysis technology, engineers propose a concept of 'post-pouring zone', namely pouring the structure is segmented, a post-pouring zone area with a certain width is reserved, and after the main structure is finished for a certain shrinkage (usually 2-4 weeks) or sedimentation stability (usually 6-12 months), the post-pouring zone is formed by adopting high-grade compensation shrinkage concrete pouring. The traditional temporary sealing cover plate is of a simple covering structure, a plywood, a steel plate or a plastic plate is generally adopted, warning lines are brushed on the surface of the traditional temporary sealing cover plate, the size of the traditional temporary sealing cover plate is approximately matched with a post-pouring slot, the traditional temporary sealing cover plate is used as a basic shielding component, meanwhile, in order to improve the sealing effect, bricks and iron wires are pressed on the edge of the cover plate manually to be simply bound on peripheral components of the slot, but in the actual use process, the traditional cover plate is simply placed above the slot, positioning is realized only by means of self weight or a weight pressed temporarily, the construction environment of a construction site is complex, the traditional temporary sealing cover plate is easily influenced by external forces such as construction collision, wind force and personnel trampling to shift and slide, the sealing state cannot be kept for a long time, sundries such as dust, sand and stone cannot be blocked, construction waste water fall into the post-pouring slot from the slot, the follow-up cleaning difficulty is increased, meanwhile, the cover plate shifting or falling down into the post-pouring slot when personnel trample is caused, and potential safety hazards exist. Disclosure of Invention The basement post-pouring belt system and the preparation method thereof provided by the invention solve the problems that the traditional temporary sealing cover plate is of a simple covering structure, is easily fixed by self weight or heavy objects and iron wires, is easily displaced and falls under the influence of external force such as construction collision, cannot be sealed for a long time, so that sundries are put into a groove to increase cleaning difficulty, and potential safety hazards of personnel falling down are also caused.
