Construction method of open caisson formwork supporting system and supporting system
The invention discloses a construction method of an open caisson formwork supporting system and the supporting system. The construction method comprises the steps that S1, a site is selected, surveying, paying-off and earth cutting are conducted, a foundation pit is formed, and the central axis of an open caisson and the contour line of the foundation pit are determined; s2, a blade foot is erected in the foundation pit, and an open caisson is manufactured through a cushion method; s3, a first section of open caisson formwork, reinforcing steel bars and embedded parts are installed; s4, a layered tiling method is adopted, concrete is poured in the open caisson formwork, and watering maintenance is conducted; s5, the open caisson formwork is dismantled, and earth is excavated for sinking; s6, the steps S3 to S5 are repeated, a second section of open caisson formwork, reinforcing steel bars and embedded parts are installed, concrete is poured, the open caisson formwork is dismantled, earth cutting and sinking are carried out, and after the Nth section of open caisson formwork is completed, earth cutting and sinking are carried out to reach the preset well bottom elevation; and S7, a reinforced concrete bottom plate is poured, and construction is completed.
本发明公开了一种沉井模板支撑体系的施工方法及支撑体系，施工方法包括：S1、选择场地，进行测量放线挖土，形成基坑，以定出沉井的中心轴线和基坑轮廓线；S2、在所述基坑内支设刃脚，并采用垫层法制作沉井；S3、安装第一节沉井模板、钢筋和预埋件；S4、采用分层平铺法，在所述沉井模板内浇筑混凝土，并进行洒水养护；S5、拆除所述沉井模板，并挖土下沉；S6、重复步骤S3至S5，安装第二节沉井模板、钢筋和预埋件，浇筑混凝土，拆除所述沉井模板并挖土下沉，直至在完成第N节沉井模板后，挖土下沉，以达到预设的井底标高；S7、浇筑钢筋砼底板，完成施工。
