Small-section tunnel lining construction process
The invention relates to the field of hydraulic engineering tunnel construction, and particularly discloses a small-section tunnel lining construction process. The small-section tunnel lining construction technology comprises the steps that S1, after an inverted arch is excavated, a base is cleaned; s2, reinforced concrete is poured into the inverted arch; s3, arch wall steel bars are bound, and concrete is poured; s4, after the arch wall concrete reaches a certain strength, maintenance is conducted; the arch wall concrete is prepared from the following raw materials in parts by weight: 900 to 1200 parts of coarse aggregate, 600 to 800 parts of fine aggregate, 240 to 300 parts of cement, 60 to 100 parts of fly ash, 50 to 70 parts of mineral powder, 140 to 190 parts of water, 7 to 11 parts of a water reducing agent and 35 to 65 parts of a shielding absorbent, wherein the shielding absorbent comprises konjac mannan, zirconium hydroxide modified chitosan and a flocculation component. The small-section tunnel lining construction process can be used for saline soil environment construction in arid areas and has the advantage of prolonging the service life of the water delivery tunnel.
本申请涉及水利工程隧洞施工领域，具体公开了小断面隧洞衬砌施工工艺。小断面隧洞衬砌施工工艺包括S1、仰拱开挖后进行基底清理；S2、仰拱内浇筑钢筋混凝土；S3、拱墙钢筋绑扎并浇筑混凝土；S4、待拱墙混凝土到达一定强度以后进行养护；所述拱墙混凝土由包括以下重量份的原料组成：粗骨料900～1200份，细骨料600～800份，水泥240～300份，粉煤灰60～100份，矿粉50～70份，水140～190份，减水剂7～11份，屏蔽吸收剂35～65份，所述屏蔽吸收剂包括魔芋甘露聚糖、氢氧化锆改性壳聚糖和絮凝组分。本申请的小断面隧洞衬砌施工工艺可用于干旱地区盐渍土环境施工，其具有延长输水隧洞寿命的优点。
