Interlocking type precast concrete block canal construction method
The invention discloses an interlocking type precast concrete block canal construction method, which comprises the following steps of: on the basis of an elevation and plane control network, measuring an elevation and plane construction control network, and carrying out site lofting; unqualified soil on the surface layer is removed and replaced, and impurities are thoroughly removed; excavating a foundation trench, and finishing a slope; segmentally constructing along the length of the water channel, uniformly paving broken stone hardcore layers on the compacted soil base at the bottom of the channel and slope protection on the two sides, compacting, and making a leveling layer and an inverted filter layer; geotextile is laid on the channel bottom and the slope protection on the two sides; paving interlocking type prefabricated concrete blocks, complementing, and pouring a coping; a concrete protection bottom is poured; cleaning the site, and completing acceptance. Each building block is meshed with six adjacent building blocks, interlocking of irregular shapes is achieved, the adjacent building blocks jointly resist the action of soil and water flow, each building block is small in area, deformation is facilitated, maintenance is also facilitated, local replacement is also facilitated, the construction speed is high, the construction period is short, the construction cost is low, and the quality is stable.
本发明公开了一种联锁式预制混凝土砌块水渠施工方法，包括：以高程和平面控制网为基础，测设高程和平面施工控制网，进行现场放样；将表层的不合格土清除置换，将杂物彻底清除；基槽开挖、修坡；沿水渠长度分段施工，渠底及两侧护坡均在夯实的土基上均匀铺设碎石垫层并夯实，并做找平层和反滤层；渠底及两侧护坡铺设土工布；铺砌联锁式预制混凝土砌块，补全、浇筑压顶；浇筑混凝土护底；清理现场、竣工验收。本发明每一砌块与相邻六个砌块相互咬合，实现了不规则外形的联锁式，使相邻砌块共同抵御土体和水流的作用，每一砌块面积不大，利于变形，维修也方便局部替换，施工速度快，工期短，建设成本低，质量稳定。
