High-pressure jet grouting pile construction technological process for expressway construction
The invention relates to the field of high-pressure jet grouting pile construction, and discloses a high-pressure jet grouting pile construction technological process for expressway construction. Secondly, holes are distributed, and the positions of the jet grouting piles are accurately distributed according to design requirements; thirdly, a drilling machine is arranged in place, and the drilling machine enters the site and is arranged on the arranged pile position; step 4, drilling; 5, tube insertion; sixthly, spraying operation is conducted; step 7, tube drawing; 8, cleaning the machine tool; and ninthly, the machine tool is moved. After the high-pressure jet grouting piles are constructed, formed soil piles have high bearing capacity and can effectively support the load of an expressway and improve the bearing capacity of a roadbed, and the high-pressure jet grouting piles can reinforce an unconsolidated stratum or a weak soil layer, improve the mechanical property of the foundation and improve the bearing capacity and stability of the foundation through grouting and pouring. And finally, high-pressure jet grouting pile construction is relatively rapid and efficient, large-area construction is achieved, construction time and labor cost can be saved, and construction efficiency is improved.
本发明涉及高压旋喷桩施工领域，公开了一种高速公路施工用高压旋喷桩施工工艺流程，包括步骤一，制备浆液；步骤二，布孔，按设计要求准确的进行旋喷桩桩位布设；步骤三，钻机就位，钻机进场安置在布设的桩位上；步骤四，钻孔；步骤五，插管；步骤六，喷射作业；步骤七，拔管；步骤八，清洗机具；步骤九，移动机具。通过高压旋喷桩施工后，形成的土体桩体具有较高的承载能力，能够有效支撑高速公路的荷载，并提高路基的承载能力，并且高压旋喷桩通过注浆灌注，可以加固松散地层或弱土层，改善地基的力学性质，提高地基的承载力和稳定性，最后高压旋喷桩施工相对快速高效，适用于大面积施工，可以节省施工时间和人力成本，提高施工效率。
