The invention discloses a double-wall steel sleeve riding well and a construction method of the double-wall steel sleeve riding well. A double-wall steel cylinder is pressed into a soil body in a static pressure manner and is connected with a steel cylinder welded to the upper portion of a pipe jacking pipe joint steel sleeve, then small guide pipe grouting is carried out to reinforce the soil body, a steel crawling ladder is welded to the inner cylinder wall in the double-wall steel cylinder, a reinforcement cage is inserted into the double-wall steel cylinder through mud replacement, micro-expansion concrete is poured, and the double-wall steel cylinder and a pipe jacking pipe joint are butt-jointed seamlessly into a whole. The riding well is prefabricated by a factory, the field splicing mode is achieved, and the double-wall steel sleeve riding well has the beneficial effects that the construction time is short, the construction efficiency is high, and the construction quality is high; meanwhile the defects that differential settlement of the riding well, water leakage between the pipe jacking pipe joint and the riding well and the like can be prevented, and the integrity and the tightness of the riding well are improved. The riding well is suitable for arrangement of a pipe diameter pipe jacking inspection well suitable for the pipe diameter being larger than 1,500 mm, andthe double-wall steel sleeve riding well is high in universality, high in construction speed, has high requirement on quality of construction progress and has good applicability in transportation flourishing regions.
本发明公开了一种双壁钢套筒骑马井及其施工方法，通过静压方式将双壁钢筒压入土体，与顶管管节钢套筒上部焊接的钢筒进行连接，然后通过小导管注浆对土体进行加固，在双壁钢筒内筒壁焊接钢爬梯，在双壁钢筒间通过泥浆置换插入钢筋笼并灌入微膨胀混凝土，实现双壁钢筒与顶管管节无缝对接，成为一个整体，该骑马井采用工厂预制，现场拼接的方式，具有施工时间短、施工效率高、施工质量高的特点，同时可防止骑马井不均匀沉降、顶管管节与骑马井之间渗水等质量缺陷的出现，提高骑马井的整体性和严密性。该骑马井适用于管径大于1500mm以上管径顶管检查井布置，其通用性强，施工速度快，对施工进度质量要求高、交通繁华地段具有很好的适用性。
