Manufacturing method of pile cap for pile foundation static load test
The invention relates to a method for manufacturing a pile cap for a pile foundation static load test. The method comprises the steps that S1, earth excavation is conducted, specifically, earth excavation is conducted to expose an over-grouting part of a reinforced concrete cast-in-place pile head; s2, base layer cleaning and removing are conducted, specifically, base layer cleaning and surface removing are conducted on the surface of the exposed pile head over-grouting part; s3, selecting and processing carbon fiber cloth: selecting different types of carbon fiber cloth and pasting thicknesses according to the magnitude of the loading load, and pre-cutting the carbon fiber cloth; s4, surface treatment and pasting are conducted, specifically, the carbon fiber cloth cut in the step S3 is coated with an adhesive, and then the carbon fiber cloth is pasted to the surface of the over-filled part of the pile head removed in the step S2; and S5, protection layer arrangement: after the carbon fiber cloth pasted in the step S4 is solidified, a protection layer is pasted on the top of the pile head over-filling part pasted with the carbon fiber cloth, and then pile cap manufacturing is completed. The construction method has the beneficial effects that the construction speed is high, concrete of the over-grouting part is directly utilized, the time for curing the cast-in-place pile cap is not needed, and reservation and machining are not needed.
本发明涉及一种桩基静载试验用桩帽制作方法，包括S1、土方开挖：土方开挖以裸露钢筋混凝土灌注桩桩头超灌部分；S2、基层清理与剔除：对裸露的桩头超灌部分表面进行基层清理、表面剔除；S3、碳纤维布料选择与加工：按照加载荷载大小选择不同类型的碳纤维布料及粘贴厚度、并将碳纤维布料预先切割好；S4、表面处理及粘贴：在步骤S3切割好的碳纤维布料上涂刷粘贴剂，然后粘贴于经步骤S2剔除处理后的桩头超灌部分表面；S5、保护层设置：待步骤S4粘贴的碳纤维布料固化后，再粘贴有碳纤维布料的桩头超灌部分顶部粘贴保护层，即完成桩帽制作。有益效果：施工速度快，且直接利用超灌部分混凝土，无需等待现浇桩帽养护时间，无需预订和加工制作。
