Construction technology for water reinforced concrete pouring socketed pile
The invention discloses a construction technology for a water reinforced concrete pouring socketed pile. The construction technology comprises the following steps that S1, pile sinking and drilling steel platform erecting are conducted, and a steel pile casing needs to be manufactured in advance; s2, measuring and releasing the elevation; s3, drilling machine in-place, wherein the hole position needs to be corrected; s4, drilling is conducted; s5, hole cleaning: measuring hole depth sediment; s6, a reinforcement cage and a sounding pipe are put down; s7, lowering a guide pipe; s8, secondary hole cleaning is conducted; and S9, underwater concrete pouring is conducted. According to the invention, the V-shaped grooves are adopted at the joints of the steel casing, so that field welding is facilitated; shroud rings with the thickness of 16 mm, the thickness of 10 mm and the height of 500 mm are additionally arranged at the top opening and the bottom opening of the pile casing, so that the rigidity of the top opening and the bottom opening of the pile casing is improved; deformation of the bottom opening of the steel casing during insertion is avoided; a spiral welding seam is adopted as a cylinder body welding seam, the outer surface of the steel casing is subjected to coating anti-corrosion treatment, sand blasting derusting is carried out before coating, and the corrosion resistance of the steel casing is guaranteed.
本发明公开了一种水上钢筋混凝土灌注嵌岩桩施工工艺,包括以下步骤:S1:沉桩及钻孔钢平台搭设:需要预先制作钢护筒;S2:测放标高;S3:钻机就位:需要校正孔位;S4:钻孔;S5:清孔:测孔深沉渣;S6:下放筋笼、声测管;S7:下导管;S8:二次清孔;S9:水下砼灌注。本发明,钢护筒接口处均采用V型坡口,便于现场焊接;护筒顶口和底口增加厚度为16mm、10mm,高度为500mm的包箍,增加护筒顶、底口的刚度;避免钢护筒底口插打时变形;筒身焊缝采用螺旋焊缝,钢护筒外表面采用涂层防腐处理,涂装前进行喷砂除锈,保证了钢护筒的耐腐蚀性能。
