Long spiral cast-in-place pile vibration pipe following construction process
The invention relates to the technical field of foundation engineering, and discloses a long spiral cast-in-place pile vibration pipe following construction process. The process comprises the following construction steps of 1, preparation before construction; 2, drilling and hole forming; 3, concrete pouring; 4, steel sleeve hammering; 5, steel reinforcement cage placing; and 6, concrete secondarypouring and steel sleeve pulling out. According to the process, concrete mortar is poured into a drilled hole through a pipe pile of a pile machine, the hole diameter of the drilled hole can be guaranteed, and the situation of hole shrinkage and hole collapse is avoided; and then a vibration hammer is used for hammering a sleeve into an original pile position poured with the concrete mortar, concrete which is not condensed at the original pile position is extruded towards the periphery, the pile diameter is increased, the diameter of a pile foundation and the combination degree of the pile foundation and the stratum are increased, and therefore the bearing strength and stability of the pile foundation are improved.
本申请涉及地基工程的技术领域，公开了长螺旋灌注桩振动跟管施工工艺，包括如下施工步骤：步骤一、施工前准备；步骤二、钻进成孔；步骤三、混凝土灌注；步骤四、钢套管的锤入；步骤五、置入钢筋笼；步骤六、混凝土二次灌注和钢套管拔除。本申请利用桩机的管桩在钻孔内灌注混凝土砂浆，可以保证钻孔的孔径，避免发生缩径塌孔的情况，随后利用振动锤将套管锤入灌注有混凝土砂浆的原桩位，原桩位未凝结的混凝土向四周挤压，扩大桩径，提高桩基的直径和与地层的结合程度，从而提高桩基的承载力度和稳定性。
