The invention belongs to the field of rush-repair engineering, and particularly discloses a rush-repair engineering construction process. The rush-repair engineering construction process comprises thefollowing steps that S0, an inner steel structure at a position to be repaired is repaired in the manner of welding or super glue bonding or the like; S1, a plurality of pieces of spherical precast concrete with the diameter of 100 mm are manufactured; S2, concrete with the slump of 90 mm to 100 mm and the aggregate granularity of 10 mm or below is preblended as outer-layer concrete; S3, the outer-layer concrete in the step 2 wraps the outer layers of the precast concrete in the step 1 to serve as rush-repaired parts, wherein the wrapping thickness is 20 mm; S4, the position to be repaired forms a semi-sealed state with an opening in the upper portion through a wood plate; S5, a plurality of precast concrete bottoming parts are manufactured, three supporting legs are arranged on the lowerportion each bottoming part, the bottoming parts are placed at the bottom of the position to be repaired, and the supporting legs of the bottoming parts are downward; and S6, the rush-repaired partsare placed in the position to be repaired from the opening. According to the scheme, the problems that a lot of positions of preformed units in the prior art are in contact, and consequently naturallyhardened concrete added later is not continuous and is likely to crack are solved.
本发明属于抢修工程领域，具体公开了一种抢修工程施工工艺，包括以下步骤：S0.通过焊接或强力胶粘接等方式将待修补处的内部钢结构修补。S1.制作若干直径为100mm的球形混凝土预制件。S2.预拌坍落度为90mm‑100mm、骨料粒度10mm以下的混凝土作为外层混凝土。S3.将步骤S2中的外层混凝土包覆在步骤S1中的预制件外层作为抢修件，包覆厚度为20mm；S4.将待修补处利用木板形成上部开口的半封闭状态；S5.制作若干混凝土预的制垫底件，垫底件下部有三条支脚。将垫底件置于待修补处的底部，使垫底件的支脚朝下。S6.将若干抢修件从开口中放入待修补处。本方案解决了现有技术预制件相互接触的位置较多，使后加的自然硬化的混凝土不连续，也较容易开裂的问题。
