While-spraying diameter measuring device and rotary spraying drilling machine
The invention relates to a jet grouting diameter measuring device and a jet grouting drilling machine, comprising a mounting body which is arranged below the jet grouting drilling machine and goes deep into a jet grouting pile hole along with a drill bit; the umbrella-shaped structure is arranged on the mounting body and is suitable for shrinking in the axial direction of the jet grouting pile hole or expanding in the side wall direction of the jet grouting pile hole; the driving piece is suitable for driving the umbrella-shaped structure to move until the end part of the umbrella-shaped structure is propped against the side wall of the jet grouting pile hole; the device has the beneficial effects that the real-time diameter of the jet grouting pile hole can be calculated, then construction parameters are adjusted, adjustment can be directly conducted in the construction process when deviation occurs, the construction efficiency is improved, the construction cost is reduced, and the construction efficiency is improved. Remedial construction does not need to be carried out after all construction is completed, the construction period is shortened, and the construction cost is saved.
本发明涉及一种随喷测径装置及旋喷钻机，包括安装本体，设置在旋喷钻机下方，随钻头深入到旋喷桩孔内；伞状结构，设置在安装本体上，适于往旋喷桩孔轴线方向收缩或者往旋喷桩孔侧壁方向张开；驱动件，适于驱动所述伞状结构移动，直至伞状结构的端部和旋喷桩孔的侧壁抵触；位移感应组件，适于对驱动件的驱动行程进行检测，计算出伞状结构的开合角度和旋喷桩孔直径，本发明具有能够计算出旋喷桩孔的实时直径，进而调整施工参数，出现偏差直接在施工过程中就能进行调整，无需等到全部施工完成之后在进行补救施工，缩短了施工工期，节约了施工成本的效果。
