Road inspection well and manufacturing process and construction method thereof

SHEN JINSHENG

The invention relates to the technical field of road inspection well construction, in particular to a road inspection well and a manufacturing process and a construction method thereof. The concrete is prepared from the following raw materials: Portland cement, medium sand, super absorbent resin, pebbles, a fiber mixture, fly ash, an expanding agent, a polycarboxylate superplasticizer, gravel-typegranules, montmorillonite powder, attapulgite, a retarder, an early strength agent and water. The fiber mixture is used as a raw material for preparing the road inspection well, wherein the fiber mixture is formed by mixing polypropylene fibers and steel fibers according to a certain proportion, as a result, the polypropylene fibers and the steel fibers are matched with each other to effectivelyreduce the volume shrinkage phenomenon of the road inspection well in the early stage, and the anti-cracking performance of the road inspection well is improved; and moreover, proper vibration compaction treatment is carried out on the concrete during pouring, so that the compactness and the uniformity of the concrete are improved and guaranteed, the crack resistance and the bearing capacity of the road inspection well are remarkably improved, and the service life of the road inspection well is effectively prolonged.

本发明涉及道路检查井施工技术领域，更具体地说它一种道路检查井及其制造工艺与施工方法；由下述原料组成：硅酸盐水泥、中砂、高吸水树脂、石子、纤维混合物、粉煤灰、膨胀剂、聚羧酸减水剂、碎石型陶粒、蒙脱石粉、凹凸棒土、缓凝剂、早强剂和水；本发明以纤维混合物作为制备道路检查井的原料，纤维混合物由聚丙烯纤维和钢纤维按照一定的比例混合而成，两者之间相互配合能有效地减小道路检查井在前期发生体积收缩的现象，提高了道路检查井的抗裂性能；再者，在进行浇筑时通过对其进行适当的振捣密实处理，使得混凝土的密实性和均匀性得到提升和保证，从而使得道路检查井的抗裂性能和承载能力得到显著的提升，有效地延长了其使用寿命。
