Low-consumable underwater pile foundation steel casing construction method
The invention discloses a low-consumable underwater pile foundation steel casing construction method, and belongs to the technical field of concrete pouring. The construction method comprises the following steps that S10, construction preparation is conducted, needed materials are determined, and perfect construction measures are established; s20, a crawler crane and a vibration hammer are used for lowering and installing an outer side steel casing; s30, after drilling is conducted through a percussion drill and other drilling machines, an inner side steel casing is installed; s40, a balance weight ring is arranged for high-pressure air cushion installation, and the high-pressure air cushion sinks to the bottom of the pile casing in the slurry environment; s50, after it is ensured that the site and equipment are in place, the reinforcement cage is hoisted, and a protection layer is arranged after lowering; s60, after the air compressor is matched with the guide pipe for secondary hole cleaning, the air compressor is used for inflating the high-pressure air cushion; s70, after ball passing and water pressing tests of the guide pipe are carried out, pile foundation concrete pouring is carried out; and S80, the high-pressure air cushion is deflated, the top end rope is hoisted and recycled, and the outer side steel casing is pulled out through a crawler crane and a vibration hammer.
本发明公开了一种低耗材水下桩基钢护筒施工方法，混凝土浇筑技术领域，该施工方法包括以下：S10：施工准备，确定所需材料，建立完善施工措施；S20：采用履带吊和震动锤下放安装外侧钢护筒；S30：利用冲击钻等钻机进行钻孔后进行内侧钢护筒安装；S40：设置配重环进行高压气垫安装，在泥浆环境下沉放到护筒底部；S50：确保现场与设备就位后起吊钢筋笼，下放后设置保护层；S60：使用空压机配合导管进行二次清孔后，利用空压机对高压气垫进行充气；S70：进行导管的通球和压水试验后，进行桩基混凝土灌筑；S80：高压气垫放气，顶端绳索吊装回收，利用采用履带吊和震动锤，拔出外侧钢护筒。
