Concrete transportation construction method for deep foundation ditch up-down synchronous total reverse construction method
The invention discloses a concrete transportation construction method for a deep foundation ditch up-down synchronous total reverse construction method. The method includes the following steps of (1)a concrete pouring double-line confluence construction procedure of a reverse beam board, and (2) a concrete pouring construction procedure of a column, a shear wall, a lining wall and other rear parts. According to the method, concrete is discharged from the first layer to a construction top layer, the concrete is transferred above a pouring point through a little-quantity concrete mixing carrierwhich is modified from a self-dumping three-wheel vehicle, and the concrete is poured to the pouring point through a funnel and a flexible pipe, so that the problem of transportation and segregationof high-grade concrete for the rear parts and beam column joints under the condition of reverse construction method characteristics are solved. Under negative third floor, a concrete delivery pump isadopted to descend to a foundation ditch from a reserved object hoisting hole, concrete is directly discharged above a pouring layer from the first layer, a pressure relief device and an inclined chute are used for transferring the concrete to a delivery pump hopper, and then the concrete delivery pump and a pump pipe are used for pouring the concrete to a pouring point, so that the problem of transportation and segregation of concrete for floors in a basement, a base board and a beam board is solved, concrete construction quality is guaranteed, the labor is saved, and engineering constructionschedule is accelerated.
深基坑上下同步全逆作法混凝土输送施工方法，包括以下内容：（一）逆作梁板混凝土浇筑双线路汇合施工流程；（二）柱、剪力墙、内衬墙等后置件混凝土浇筑施工流程。本发明采用混凝土从一层直卸至施工顶层+自卸三轮汽车改装的少方量混凝土搅拌运输车转运至浇筑点上方+漏斗、软管至浇筑点方式解决逆作法特性条件下后置件、梁柱接头高标号混凝土的运输与离析问题；负三层以下采用混凝土输送泵从已预留的吊物孔下基坑，混凝土从一层直卸至浇筑层上方+卸压装置+斜溜槽转至输送泵料斗，再由混凝土输送泵+泵管至浇筑点方式解决地下室楼层、底板梁板混凝土的运输与离析问题，从而确保混凝土施工质量，并节约劳动力，加快工程施工进度。
