Cast-in-place riding well construction method
The invention relates to the technical field of municipal pipe network construction, in particular to a cast-in-place riding well construction method which comprises the following steps: after earth is excavated to a designed elevation, a well chamber cushion layer and a well chamber bottom plate are constructed; well chamber pool wall and top plate construction; the pool wall below the top of the original pipeline and the surface of the part, located in the well chamber, of the original pipeline are subjected to scabbling treatment and filled with micro-expansion concrete, the top face of the micro-expansion concrete is flush with the top face of the original pipeline, and holes are formed in the original pipeline after micro-expansion concrete construction is completed; a concrete module is adopted for shaft construction, waterproof cement mortar is adopted for shaft base mortar, pointing and plain concrete hole filling, and the waterproof cement mortar is adopted for smearing triangular mortar on the outer side of the contact position of the shaft and a well chamber top plate; according to the method, the cushion layer and the bottom plate are additionally arranged on the bottom layer of the horse-riding well, the foundation bottom plate is expanded, the expanded foundation can provide more stable bearing force for the horse-riding well, and the problem that an original pipeline is squeezed due to the fact that the horse-riding well body is directly erected on an original pipeline body is solved.
本发明涉及市政管网建设技术领域，特别是涉及一种现浇骑马井施工方法，包括如下步骤：土方开挖至设计标高后进行井室垫层及井室底板施工；井室池壁及顶板施工；将原管道顶部以下的池壁、原管道位于井室内的部分表面凿毛处理，采用微膨胀混凝土填实，微膨胀混凝土顶面与原管道顶面持平，微膨胀混凝土施工完成后在原管道上开孔；采用混凝土模块进行井筒施工，防水水泥砂浆对井筒座浆、勾缝，素混凝土灌孔，井筒与井室顶板接触位置外侧采用防水水泥砂浆抹三角灰；本方法通过在该骑马井底层加设垫层和底板，扩大了基础底板，扩大的基础能够为骑马井提供更稳定的承载力，避免了骑马井主体直接架设在原管道主体上，对原管道造成挤压问题。
