老龙嘴水电站工程，溢流坝段长60.2米的小石子混凝土单曲拱坝，历经230天不分昼夜的施工，顺利完成616.25高程以下全部施工任务，左右两侧的非溢流坝段已浇筑至623高程。施工期间，施工人员合理组织导流及排水，攻克大体积混凝土悬挑结构支模难题，克服无塔吊协助和拌合站搅拌能力限制等重重困难，吊车驻扎、拌合站连轴转、混凝土罐车循环跑，一斗斗、一点点、一块块的将大坝硬生生的“抬”了起来。

引水隧洞为直径3.2米圆形有压隧洞，全断面40公分厚衬砌本施工难度大，从3月起，施工人员定制9米半圆形钢模台车进场，配合木模散拼，跳仓流水作业，于6月27日完成204.41米的全断面衬砌浇筑，所有关键点工作已逐个突破。剩余连接段、岔支管施工正在有序开展。

Laolongzui Hydropower Station project, overflow dam section of 60.2 meters of small stone concrete single arch dam, after 230 days of day and night construction, successfully completed all the construction tasks below 616.25 elevation, left and right sides of the non-overflow dam section has been poured to 623 elevation. During the construction period, the construction personnel rationally organized the diversion and drainage, overcome the problems of the large-volume concrete cantilever structure support, overcome the difficulties such as the absence of tower crane assistance and the mixing capacity of the mixing station, and so on, the crane stationed, the mixing station rotating, and the concrete tank truck running in circulation, and the dam was "lifted" one bucket, little by little, and the block by block.

The diversion tunnel is a 3.2-meter-diameter circular pressure tunnel with a 40cm thick lining. The construction is very difficult. Since March, the construction personnel have customized a 9-meter-semicircular steel model truck to enter the tunnel, and completed the pouring of 204.41 meters of the full-section lining on June 27, with the help of wood model disassembling and warehouse jumping, and all key points have been broken through one by one. The construction of the remaining connecting sections and branch pipes is being carried out in an orderly manner.
