Orifice pipe imbedding method under deepwater condition and inflatable bag
The invention discloses an orifice pipe imbedding method and an inflatable bag under a deepwater condition, and relates to the field of orifice pipe imbedding, and the method comprises the following steps: S1, construction preparation: placing a drilling machine and construction equipment in place, entering constructors and assembling the construction equipment; s2, a hole position is determined, specifically, a diver enters the water to observe a deposition layer of the underwater part of the drilling area and determine the hole position; s3, drilling is started, and a drill rod with a drill bit is lowered from the water surface platform to the hole site section by section for drilling; s4, air bag inflation and drilling grouting are conducted, all drill rods are pulled up, core samples are checked to determine the geological condition of the stratum of the section, a drill bit is replaced, the air bag is used, an arc-shaped groove is formed, the physical contact area and friction force between the air bag and the external hole wall are increased, the functionality of the air bag in underwater drilling grouting application is improved, and the service life of the air bag is prolonged. The reliability and the safety of the air bag in the using process are further enhanced, and meanwhile the auxiliary mechanism can enable the air bag to be expanded more smoothly, stably and evenly.
本发明公开了一种深水条件下的孔口管镶铸方法及充气囊，涉及孔口管镶铸领域，包括以下步骤：S1，施工准备，包括钻机和施工设备就位，施工人员进场以及装配施工设备；S2，确定孔位，潜水员下水对钻孔区域水下部分的淤积层进行观察并确定孔位；S3，开始钻孔，从水面平台上在孔位上将带钻头的钻杆逐节下放进行钻孔；S4，气囊充气，钻孔灌浆，将所有钻杆拔起，并查看芯样确定该段地层地质情况，更换钻头，通过使用气囊并且设置弧形凹槽，增加气囊与外部孔壁的物理接触面积和摩擦力，不仅提高了气囊在水下钻孔灌浆应用中的功能性，还进一步增强了气囊使用过程中的可靠性和安全性，同时辅助机构可以让气囊的膨胀更加平整，稳定和均匀。
