Concrete pouring body and construction method thereof
The embodiment of the invention discloses a concrete pouring body and a construction method thereof. The concrete pouring body can comprise a prefabricated reinforcement cage, an anti-crack net and an anti-crack concrete layer; the anti-crack net is fixed on the outer side of the prefabricated reinforcement cage; concrete is poured into a peripheral formwork fixed to the position, at the preset distance, of the outer side of the prefabricated reinforcement cage, the concrete pouring body is obtained, and the obtained concrete pouring body comprises an anti-crack concrete layer with the thickness equal to the preset distance value; the tensile strength of the anti-crack steel bars is larger than the preset tensile strength, and the diameter of the anti-crack steel bars in the anti-crack net is smaller than the preset percentage of the thickness of the anti-crack concrete layer, so that the anti-crack net can be completely located in the anti-crack concrete layer, and the internal stress on the anti-crack concrete layer is reduced; therefore, the anti-cracking performance of the anti-cracking concrete is effectively improved, the anti-cracking effect is achieved, and the service life of a concrete pouring body structure is effectively prolonged.
本说明书实施例中公开了一种混凝土浇筑体及其施工方法，混凝土浇筑体可以包括，预制钢筋笼、抗裂网以及抗裂混凝土层；抗裂网固定于所述预制钢筋笼的外侧；向固定于所述预制钢筋笼外侧的预设距离处的外围模板中浇筑混凝土得到所述混凝土浇筑体，其中，得到的混凝土浇筑体包括厚度为所述预设距离值的抗裂混凝土层；由于抗裂钢筋的抗拉强度大于预设抗拉强度，且抗裂网中的抗裂钢筋的直径小于所述抗裂混凝土层的厚度的预设百分比，使得抗裂网能够完全位于抗裂混凝土层内，并减小对抗裂混凝土层的内应力，从而有效提高抗裂混凝土的抗裂性能达到抗裂的效果，进而有效延长混凝土浇筑体结构的使用寿命。
