1 混凝土空箱装配式建筑物简介混凝土空箱装配式建筑物,简单地讲,就是将混凝土预制实体结构改为空箱结构,按照设计要求将预制的混凝土空箱构件分层进行装配砌筑,空箱内填充砂、砾料或砂性土料夯实密封,充分利用混凝土箱壁和箱内充填砂、砾料的作用,发挥其混凝土空箱的承压性能和防冻胀、防冲刷、防盐碱侵蚀破坏之功能作用的建筑物结构体。2 混凝土预制空箱构件的设计原则2.1 充分利用混凝土材料力学的抗压性能在灌区斗农渠系建筑物中,桥、闸的建筑体积一般都不很
1 empty concrete box assembly structure Brief introduction Concrete empty box assembly type building, simply put, that is, the concrete prefabricated entity structure to empty box structure, according to the design requirements will be prefabricated concrete empty box components for assembly masonry, Empty box filling sand, gravel or sand material tamp seal, make full use of concrete box wall and the box filled with sand, gravel effect, to play its concrete empty box pressure performance and frost heaving, anti-erosion, salt Alkali erosion damage function of the building structure. 2 prefabricated empty concrete box design principles 2.1 make full use of mechanical properties of concrete compressive properties in the irrigation bucket bucket canal buildings, the construction of the bridge, gate size is generally not very
