Explosion-proof workshop foundation static pressure pile construction method
The invention provides an explosion-proof workshop foundation static pressure pile construction method. The explosion-proof workshop foundation static pressure pile construction method comprises the following steps that S1, a soft soil section is compacted; s2, prefabricating a pile head and a pile body of the static pressure pile, and performing controlled lofting by a measurement group after the field is leveled; s3, after equipment debugging is completed, a walking device on the piling machine is used for moving and walking in place; the pile head is hoisted through a pile machine crane, a pile machine oil pump is started to hold the pile, the pile head is fixed and pressed downwards, and the lower end of the pile head is inserted into the ground through slow pressing; and S4, the perpendicularity of the pile body is corrected in the pile pressing process, along with pile pressing, after the pile head is pressed into the soil layer, pile body splicing, continuous pile pressing and splicing are conducted at the end of the pile head, and the pile body is pressed to the preset pressure or the preset elevation. The grouting pipe and the grout outlet pipe are arranged on the pile head, so that the supporting capacity of the static pressure pile is improved through grouting while the static pressure pile has static pressure construction, the stability of supporting a building is improved, and the quality of the building is improved.
本发明提供一种防爆车间地基静压桩施工方法，包括以下步骤：步骤S1，对松软土地段采取压实处理；步骤S2，预制静压桩的桩头和桩身，场地平整后由测量组进行控制放样；步骤S3，设备调试完毕后，利用桩机上行走装置、移动行走就位；利用桩机起重机起吊桩头，开动桩机油泵抱桩、固定、下压桩头，缓缓下压使桩头下端插入地面；步骤S4，在压桩过程中对桩身垂直度进行纠正，随着压桩的进行，桩头压入土层后，在桩头的端部进行桩身拼接，持续压桩和拼接，使桩身压至预设压力或者预设标高。在桩头设置注浆管和出浆管，从而使静压桩具备静压施工的同时，通过注浆增加静压桩的支撑能力，从而提高对建筑物支撑的稳定性，提高建筑物质量。
