Construction method for rotary excavating and pouring secant pile
The invention relates to a construction method for a rotary excavating and pouring secant pile, which comprises the following steps of: drilling a plurality of pile holes in the ground, and enabling any two adjacent pile holes to be meshed and communicated with each other; a guide pipe is provided, one pile hole serves as a current pile hole, the lower end of the guide pipe extends into the current pile hole, and then the upper end of the guide pipe is filled with foam particles; concrete is poured from the upper end of the guide pipe, then the guide pipe is lifted, the foam particles are extruded by the concrete and overflow between the guide pipe and the current pile hole in the direction from bottom to top, and the steps are repeated till all the pile holes are filled. By the adoption of the technical scheme, in the construction procedure of pouring concrete, the white foam particles are used for prompting constructors, so that the constructors can master the accumulated elevation of the concrete in the pile hole in time, then the constructors are guided to control the concrete pouring amount and the concrete pouring speed, the pile hole is densely filled with the concrete, and the construction efficiency is improved. And the pile forming strength and the bearing capacity of the secant pile are ensured.
本发明涉及一种旋挖灌注咬合桩施工方法，包括以下步骤：在地面上钻取若干个桩孔，并且使任意相邻两个桩孔相互咬合连通；提供导管，将其中一个桩孔作为当前桩孔，先将导管下端伸入当前桩孔内，再从导管上端填充泡沫颗粒；先从导管上端浇注混凝土，然后提升导管，使泡沫颗粒受到混凝土的挤压，沿着自下而上的方向，在导管与当前桩孔之间溢升，重复上述步骤直至将所有桩孔填满。采用本发明的技术方案，在灌注混凝土的施工工序中，通过白色的泡沫颗粒对施工人员作出提示，使施工人员及时掌握混凝土在桩孔内累计高程，继而引导施工人员控制混凝土灌注量和混凝土灌注速度，使混凝土在桩孔内填充密实，保证咬合桩成桩强度和承载能力。
