Inclined strut and inclined strut inner core dismantling device of synchronous concentric cement-soil composite inclined strut pile
The invention relates to the technical field of foundation pit support, in particular to a synchronous concentric cement soil composite diagonal bracing pile diagonal bracing and diagonal bracing inner core dismantling device which comprises a rigid pipe body and a tubular lining coaxially arranged on the inner wall of the rigid pipe body, and the tubular lining extends in the length direction of the rigid pipe body. In the working state, after the rigid pipe body is obliquely inserted into a foundation pit, the cement-based material is poured into the tubular lining to form an inner core, in the working state, the rigid pipe body is obliquely inserted into the foundation pit, then the cement-based material is poured into the tubular lining to form an inclined strut, and the top end of the inclined strut abuts against the inclined face of the crown beam. After a cement-based material is injected into the tubular lining to form a stable inclined strut structure, the rigid pipe body is taken out of the foundation pit, the tubular lining is melted by heating the rigid pipe body, the solidified cement-based material is lubricated, the cement-based material can be separated from the rigid pipe body, the steel pipe can be recycled repeatedly, and the service life of the steel pipe is prolonged. Therefore, the construction cost is saved.
本发明涉及基坑围护技术领域，具体是涉及一种同步同心水泥土复合斜撑桩的斜撑及斜撑内心拆除装置，包括刚性管体，以及同轴设置在刚性管体内壁的管状内衬，管状内衬沿刚性管体的长度方向延伸，管状内衬中灌注有水泥基材料以形成内心，工作状态下，将刚性管体斜插入基坑后向管状内衬中灌注水泥基材料以形成斜撑，斜撑的顶端抵接在冠梁的斜面处，本发明通过在刚性管体内设置遇热熔融的管状内衬，使得在向管状内衬中注入水泥基材料后以形成稳定的斜撑结构后，将刚性管体从基坑中取出，通过加热刚性管体，使管状内衬熔融并对凝固的水泥基材料起到润滑的作用，能够将水泥基材料与刚性管体分离，便于重复回收钢管，以此节约施工成本。
