Widening and filling construction method for large-particle-size construction waste light embankment
The invention discloses a widening and filling construction method for a large-particle-size building waste light embankment. The widening and filling construction method comprises the following construction steps of (1) construction preparation; (2) waste crushing; (3) the mixing proportion of the waste concrete light backfill body is designed; (4) treating a roadbed in a roadbed widening area; (5) a side formwork is erected; and (6) construction of the waste concrete light backfill body. Waste concrete is firstly crushed through the pressurizing device, then auxiliary crushing is conducted through the second water sprayer, dust on the surface of waste concrete aggregate is reduced, vibration screening is conducted on the waste concrete aggregate through the first aggregate screen, and the accuracy of particle size control over the waste concrete aggregate is improved; waste concrete light backfill body materials are adopted in the widened area foundation, and inclined reinforcement bodies are inserted, so that the bearing capacity of a foundation soil body is improved; an assembly type formwork is adopted on the side face of the widened area, the problem of mold disassembly and assembly is avoided, the transverse position of the transverse tie bar is controlled through the tie bar adjusting bolt, and dynamic control over the transverse tie bar is achieved.
一种大粒径建筑废弃物轻质路堤加宽填筑施工方法，包括以下施工步骤：1）施工准备；2）废弃物破碎；3）废弃混凝土轻质回填体配合比设计；4）路基加宽区域地基处理；5）侧模支设；6）废弃混凝土轻质回填体施工。本发明首先通过加压装置对废弃混凝土进行破碎，然后通过第二喷水器进行辅助破碎，减小废弃混凝土集料表面灰尘，并通过第一集料筛网对废弃混凝土集料进行振动筛分，改善废弃混凝土集料粒径控制的准确度；在加宽区基础采用废弃混凝土轻质回填体材料，并插入斜向加筋体，提高了地基土体的承载能力；在加宽区域侧面采用装配式模板，避免了拆、装模具的问题，并通过拉结筋调节栓控制横向拉结筋的横向位置，实现对横向拉结筋的动态控制。
