Grouting pipe construction method for post grouting of cast-in-place pile
The invention discloses a grouting pipe construction method for post grouting of a cast-in-place pile. The grouting pipe construction method comprises the steps of manufacturing pile side grouting hoses, and forming side grout outlet holes in the preset positions of the manufactured pile side grouting hoses; installing a plurality of pile side grouting hoses on the pile side along the peripheral side of a reinforcement cage in a surrounding mode, so that the sides, with the side grout outlet holes, of the pile side grouting hoses are arranged in a protruding mode away from the reinforcement cage, outer protruding parts are formed on the outer sides of the pile side grouting hoses, and inner concave parts are formed on the inner sides of the pile side grouting hoses; installing a plurality of pile side grouting pipes in the preset position of the reinforcement cage, and communicating grout outlet holes in the bottoms of the pile side grouting pipes with pipe bodies of the pile side grouting hoses; installing a pile bottom grouting pipe at the bottom of the reinforcement cage, so that the bottom of the pile bottom grouting pipe extends out of the bottom of the reinforcement cage by a preset length; and connecting the pile side grouting pipes and the pile bottom grouting pipe with a grouting device. According to the grouting pipe construction method, the situation that the grout outlet holes of the grouting pipes are completely wrapped by concrete can be avoided, follow-up grouting is in a smooth state, and the construction quality of a pile foundation is improved.
本申请公开了一种灌注桩后注浆的注浆管施工方法，其包括：制作桩侧注浆软管，并在做好的桩侧注浆软管预定位置处开设侧出浆孔；在桩侧沿钢筋笼外周侧环绕安装若干所述桩侧注浆软管，使得所述桩侧注浆软管上开设有侧出浆孔的一侧远离钢筋笼凸出设置，以在桩侧注浆软管的外侧形成外凸部、内侧形成内凹部；在钢筋笼的预定位置安装多个桩侧注浆管，将桩侧注浆管的底部出浆孔与桩侧注浆软管的管身相连通；在钢筋笼的底部安装桩底注浆管，使桩底注浆管底部延伸出钢筋笼底部预定的长度；将桩侧注浆管以及桩底注浆管分别与压浆器相连接。本申请能够避免注浆管的出浆孔被混凝土完全包裹的情况，使得后续注浆处于通畅状态，提高桩基的施工质量。
