Pipe pile core filling concrete pouring construction method
The invention belongs to the technical field of tubular pile construction, and particularly relates to a tubular pile core filling concrete pouring construction method. Comprising the following steps that S1, accumulated water at the bottom of a pipe pile core is pumped and drained; s2, after accumulated water at the bottom of the pile core is completely discharged, the bottom of the pipe pile core is backfilled with plain soil, the particle size of the plain soil backfilled with the pile core is smaller than 1/2 of the diameter of the pile core, and the particle sizes of the plain soil in the pile core are sequentially reduced from bottom to top; s3, C15 bottom building concrete is poured above plain soil backfilled with the pile core; s4, after the bottom building concrete is solidified, the side wall of the pile core is cleaned; s5, a reinforcement cage is placed in the pile core; s6, core filling concrete is poured on the reinforcement cage of the pile core; the top elevation of pile core backfill plain soil is 60 cm higher than the bottom elevation of core filling concrete, and 10 cm is reserved for avoiding over-pouring of bottom building concrete; according to the construction method, the situation that concrete at the bottom of the core filling reinforcement cage is lost from the gaps and consequently the concrete on the lower portion is loosened when the pile core of the pipe pile is filled with concrete can be avoided.
本发明属于管桩施工技术领域，具体涉及一种管桩填芯混凝土浇筑施工方法；包括以下步骤：S1：对管桩桩芯底部积水进行抽排；S2：桩芯底部积水被完全排出后，对管桩桩芯底部回填素土，所述桩芯回填素土的粒径小于桩芯直径的1/2，且桩芯内由下至上的素土粒径依次减小；S3：在桩芯回填的素土上方浇筑C15筑底混凝土；S4：在筑底混凝土凝固后，对桩芯侧壁进行清洗；S5：在桩芯内安放钢筋笼；S6：在桩芯的钢筋笼上浇筑填芯混凝土；桩芯回填素土顶标高比填芯混凝土底标高低60cm，预留10cm用于避免筑底混凝土超灌；本发明的施工方法能避免在管桩的桩芯填充混凝土时出现填芯钢筋笼底部的混凝土从缝隙中流失导致下部混凝土松散。
