Follow-up pile casing suitable for sandy gravel stratum and construction method thereof
The invention relates to the technical field of rotary drilling machines, in particular to a follow-up pile casing suitable for a sandy gravel stratum and a construction method thereof. The follow-up pile casing comprises at least one section of follow-up pile casing body, a first butt joint and a second butt joint are arranged at the two ends of the at least one section of follow-up pile casing body respectively, the two sections of follow-up pile casing bodies can be connected through the arrangement of the first butt joint and the second butt joint, a clamping block is arranged on the second butt joint, a clamping groove matched with the clamping block is formed in the inner surface of the first butt joint, and a spiral wall is arranged on the outer surfaces of the follow-up pile casing bodies. The spiral wall is arranged on the outer surface of the follow-up pile casing, so that the follow-up pile casing is easier to go deep into the sandy gravel stratum, and meanwhile, the repeated follow-up pile casing is pulled out in time in the construction process, so that the engineering construction cost is saved.
本发明涉及旋挖机技术领域，具体为一种适用于砂卵石地层的跟进护筒及其施工方法；包括至少一节跟进护筒本体，所述跟进护筒本体两端分别为第一对接头和第二对接头，所述第一对接头和第二对接头的设置可使两节跟进护筒本体相接，所述第二对接头上设置有卡块，所述第一对接头内表面上设置有与卡块相匹配的卡槽，所述跟进护筒本体外表面上设置有螺旋壁；本发明在跟进护筒外表面设置螺旋壁，让跟进护筒更容易深入砂卵石地层内，同时在施工过程中及时拔出重复跟进护筒，因此节约了工程施工成本。
