Offshore steel pipe distributed post-grouting device, air-type grouting assembly and construction method
The invention discloses an offshore steep pipe distributed post-grouting device, an air-type grouting assembly and a construction method. The air-type grouting assembly comprises a grouting pipe for being placed into a vertical square grouting channel, square rubber air bags which are wrapped on the outer side of the grouting pipe at upper and lower intervals, an upper air pipe connected with thesquare rubber air bag at the upper end to inflate the square rubber air bag, and a lower air pipe connected with the square rubber air bag at the lower end to inflate the square rubber air bag, and aplurality of slurry outlets are uniformly formed in the outside surface, avoiding the square rubber air bags at the upper and lower ends, of the grouting pipe; and the square rubber air bags are filled under the action of external air pressure, and the square rubber air bags at the upper and lower ends under the sufficient air state form a local closed space with the vertical square grouting channel. According to the air-type grouting assembly, a closed space is formed by using the square rubber air bags arranged up and down and the inner wall of the vertical square grouting channel under sufficient air state, and the local grouting in the vertical square grouting channel is achieved.
本发明公开了一种海上钢管桩分布式后压浆装置与气式压浆组件及施工方法，气式压浆组件包括用于放入竖向方形压浆通道内的压浆管、上下间隔包覆在压浆管外侧的方形橡胶气囊、与上端的方形橡胶气囊相连接为方形橡胶气囊充气的上气管以及与下端的方形橡胶气囊相连接为方形橡胶气囊充气的下气管，所述压浆管避开上、下两端的方形橡胶气囊的外侧表面均布有若干个出浆口；所述方形橡胶气囊在外部气压作用下充盈，足气状态下的上、下两端的方形橡胶气囊与竖向方形压浆通道内壁形成局部密闭空间。本发明的气式压浆组件利用足气状态下的上下设置的方形橡胶气囊以及竖向方形压浆通道内壁形成密闭空间，实现竖向方形压浆通道内局部位置的压浆。
