Simple and quick mounting and positioning method for first section of prefabricated pipe gallery
The invention discloses a simple and quick mounting and positioning method for a first section of a prefabricated pipe gallery. The simple and quick mounting and positioning method comprises the following steps of (1) precisely positioning and mounting the first section on a cushion layer; (2) coaxially mounting a fixed section in front of the first section, and forming a gap between the fixed section and the first section; (3) tensioning and connecting the fixed section and the first section through prefabricated pipe gallery tensioning holes by adopting four threaded ribs; (4) tensioning the threaded ribs through a jack; and (5) pouring a reinforcing layer between the first section and the cushion layer after tensioning is completed, and tensioning and connecting a second section, a third section and a fourth section to the end, away from the fixed section, of the first section in sequence through the threaded ribs after the strength of the reinforcing layer reaches 90% or above. According to the simple and quick mounting and positioning method, the problems that in the prestressed tendon tensioning process, the positioning of the first section can be influenced by subsequent prefabricated pipe gallery sections, and then the axis and plane position precision of the subsequent pipe gallery sections and the waterproof effect of the bell and spigot positions are influenced in the prior art are solved.
本申请公开了一种简易快速预制管廊首节段安装定位方法，包括如下步骤：(1)将第一节段精准定位安装至垫层上；(2)在第一节段的前方同轴线安装固定节段，并使固定节段和第一节段之间具有间距；(3)将固定节段与第一节段通过预制管廊张拉孔采用四根螺纹筋进行张拉连接；(4)通过千斤顶对螺纹筋进行张拉；(5)张拉完成后在第一节段和垫层之间灌注加固层，在加固层强度达到90％以上后在第一节段远离固定节段的一端依次通过螺纹筋张拉连接第二节段、第三节段和第四节段。本申请解决了相关技术中在预应力筋张拉过程中后续预制管廊节段将会对首节段定位造成影响，进而影响后续管廊节段轴线、平面位置精度及承插口处防水效果的问题。
