High-strength prestressed concrete square pile construction technology
The invention discloses a high-strength prestressed concrete square pile construction process, relates to the technical field of square pile construction processes, and aims to solve the problems that in the prior art, adjacent square piles cannot be positioned through fixed square piles, the positions of the square piles are easy to deviate during pile pressing, perpendicularity detection needs to be carried out for many times, and the construction efficiency is high. The construction efficiency is reduced, only one square pile can be pressed each time, and the construction period is long. The construction technology comprises the following steps that S1, construction preparation is conducted; s2, measuring and setting out; s3, pile hoisting; s4, pressing the piles; S5, splicing the piles; s6, pile sinking; s7, final pressing; s8, pile cutting; and S9, pressing the square piles on the outer side. According to the construction technology, by means of the design of the guide sleeves, the adjacent square piles can be positioned through the fixed square piles, the adjacent square piles are prevented from deviating in the downward pressing process, perpendicularity detection does not need to be conducted many times, the construction efficiency is improved, pile pressing operation can be conducted on the two square piles at the same time, and therefore the construction period is shortened.
本发明公开了一种高强度预应力混凝土方桩施工工艺，涉及方桩施工工艺技术领域，该施工工艺旨在解决现有技术下不能通过已固定的方桩对相邻的方桩进行定位，在压桩时方桩的位置易偏移，需要多次进行垂直度的检测，降低施工的效率，且每次只能对一根方桩进行压桩操作，施工周期长的技术问题。该施工工艺，其步骤如下：S1：施工准备；S2：测量放样；S3：吊桩；S4：压桩：S5：接桩；S6：沉桩；S7：终压；S8：截桩；S9：外侧方桩的压桩。该施工工艺利用导向套的设计，可以通过已固定的方桩对相邻的方桩进行定位，防止相邻方桩在下压时发生偏移，不需要多次进行垂直度的检测，提高施工的效率，可以同时对两根方桩进行压桩操作，从而缩短施工周期。
