Ocean engineering cast-in-place pile construction method
The invention relates to the technical field of foundations and ocean engineering, and aims to provide an ocean engineering cast-in-place pile construction method. The retaining wall cast-in-place pile built according to the ocean engineering cast-in-place pile construction method is high in bending strength and shearing strength and good in safety. The ocean engineering cast-in-place pile construction method comprises the following steps that a hole is formed through an all-casing construction method, and a casing pipe is reserved in the drilled hole; a hollow wall protection pipe is placed in the sleeve; slurry is injected between the outer wall of the wall protecting pipe and the inner wall of the drill hole, and meanwhile the sleeve is pulled out; and a reinforced concrete structure is arranged in the wall protecting pipe. According to the grouting consolidation method, the problems that in a grouting consolidation method for guiding the precast pile through full-casing drilling in the prior art, when the connecting part of the precast pile is located above a seabed, the bending strength and the shearing strength are low, and potential safety hazards exist are solved.
本发明涉及地基基础和海洋工程技术领域，其目的是提供一种海洋工程灌注桩施工方法。按这种海洋工程灌注桩施工方法建造的护壁灌注桩抗弯和抗剪强度较高、安全性好。上述海洋工程灌注桩施工方法包括以下步骤：通过全套管工法成孔并在钻孔内预留套管；将中空的护壁管放入套管内；向护壁管外壁与钻孔内壁之间注入浆料，同时拔出套管；向护壁管内置入钢筋混凝土结构。本发明解决了现有技术中的全套管钻孔导引预制桩的注浆固结方法中当预制桩连接部位处于海床之上时抗弯和抗剪强度较低、存在安全隐患的问题。
