Manufacturing method of multi-head concrete rammed and expanded pile
The invention discloses a manufacturing method of a top-down multi-ramming expanding head concrete pile. The manufacturing method comprises the following steps that 1, the ramming expanding position is determined; 2, a pile driver is in place; 3, the inner pipe and the outer pipe are sunk to the uppermost ramming and expanding position; 4, the inner pipe is pulled out; 5, concrete is poured; 6, aninner pipe is inserted; 7, the outer pipe is pulled upwards by h; 8, ramming is performed to form a ramming and expanding head; 9, the inner pipe and the outer pipe are sunk to the position of the next ramming and expanding head; 10, the inner pipe is pulled out; 11, concrete is poured; 12, an inner pipe is inserted; 13, the outer pipe is pulled up by h; 14, ramming is performed to form a rammingand expanding head; 15, the steps are executed repeatedly to form all ramming and expanding heads; 16, the multi-head concrete rammed and expanded pile is obtained. According to the method, the ramming heads are obtained through gradual ramming from top to bottom, it is guaranteed that each section of ramming head can reach the preset outer diameter, and it is guaranteed that the D value meets the preset construction requirement through the method that the D value and the h value are determined firstly and then the H value is determined.
本发明公开了一种自上而下多夯扩头混凝土桩的制作方法，包括如下步骤：步骤一、确定扩夯位置；步骤二、打桩机就位；步骤三、下沉内外管至最上方夯扩位置；步骤四、拔内管；步骤五、灌注混凝土；步骤六、插内管；步骤七、外管上拔h；步骤八、夯击形成夯扩头；步骤九、下沉内外管至下一处夯扩头位置；步骤十、拔出内管；步骤十一、灌注混凝土；步骤十二、插入内管；步骤十三、外管上拔h；步骤十四、夯击形成夯扩头；骤十五、重复上述步骤形成所有夯扩头；骤十六、得到多头混凝土夯扩桩。本发明通过自上向下逐渐扩夯得到夯扩头，保证了每段夯扩头均能达到预设的外径，且通过先确定D和h值后，再确定H的值的方法保证了D值符合预设的建造要求。
