1964年我们就某河网地区的木桥进行了调查研究,并对木桥小修保养进行了试点工作,取得了一定的成果。现谈谈工作中的一些做法与体会。这个地区的河流错综迂迴,桥梁特多,仅以其中一个县的省养公路为例,平均每公里就有桥梁11米,其中木桥及木桥面又占桥梁总长度的80%,一部分是解放初期抢修通车的,一部分是1957～1959年重建或加固的,根据记载和观察,由于失于维修保养,木桥负荷能力及技术状况显著下降,已有约30%的木桥成为危桥,个别的已严重到要下客卸贷过桥。桥梁损坏的原因,从主客观因素分析如下:(一)主观方面:1.由于重修轻养,在未出现危桥以前没有注意进行小修保养工作,中修工作不彻底,修后又未及时维修,加之一部分木桥未作防腐处理,同时以往对木桥
In 1964, we conducted a survey on the wooden bridges of a river network area, carried out pilot work on minor maintenance of wooden bridges, and achieved certain results. Now talk about some of the practices and experience at work. The rivers in this area are complicated and have many bridges. Take the provincial highways in one of the counties as an example. On average, there are 11 meters of bridges per kilometer, of which, wooden bridges and wooden bridges account for 80% of the total length of the bridge. In the early days of the liberation, about 30% of the wooden bridges became dangerous bridges due to the loss of maintenance and repair, significant reduction in the load capacity and technical conditions of the wooden bridges, and some of them were rebuilt or reinforced from 1957 to 1959. According to records and observations, Individuals have been severely under the passenger off the loan bridge. The reasons for the damage of the bridge, from the subjective and objective factors are as follows: (A) Subjective Aspects: 1. As a result of rehabilitation light, did not appear before the Bridge did not pay attention to minor maintenance work, repair work is not complete, repair and repair , In addition to a part of the wooden bridge without preservative treatment, at the same time on the wooden bridge
