High-pressure jet grouting pile construction method based on PVC floral tube
The invention provides a high-pressure jet grouting pile construction method based on a PVC floral tube. The method comprises the following steps that 1, geological exploration is conducted on geology needing to be constructed; 2, the PVC floral tube is manufactured; 3, a geological drilling rig is used for drilling a hole in the ground to be constructed, after the hole is drilled to the designed depth, a drill rod of the geological drilling rig is pulled out immediately, and the PVC floral tube with the diameter matched with the hole diameter is inserted into the hole; 4, cement grout is prepared; and 5, a high-pressure jet grouting pile drill bit of a high-pressure jet grouting pile machine is inserted into the inner bottom of the hole, the high-pressure jet grouting pile drill bit conducts high-pressure jet grouting in the hole from bottom to top, and in the high-pressure jet grouting process, the cement grout sprayed out of the high-pressure jet grouting pile machine can cut up the PVC floral tube in the hole. According to the high-pressure jet grouting pile construction method based on the PVC floral tube, the construction efficiency and quality of a high-pressure jet grouting pile can be improved.
本发明提供了一种基于PVC花管的高压旋喷桩施工方法，包括以下步骤：步骤一：对需要进行施工的地质进行地质勘探；步骤二：制作PVC花管；步骤三：通过地质钻机对待施工的地面进行钻孔，钻至设计深度后，立刻拔出地质钻机的钻杆，在孔内插入直径与孔径适配的PVC花管；步骤四：制备水泥浆液；步骤五：把高压旋喷桩机的高压旋喷桩钻头插入孔的内底部，高压旋喷桩钻头在孔内由下往上进行高压旋喷注浆，高压旋喷注浆过程中，高压旋喷桩机喷出的水泥浆液能够将孔内的PVC花管切碎。本发明能够提高高压旋喷桩施工效率和质量。
