Taixin small rotary excavation participated in Nanjing dam reinforcement project

in recent years, the situation of flood control and disaster resistance is severe, and the reinforcement project of the old dam is being implemented in an orderly manner. In January 2017, Taixin small rotary excavation was lucky to participate in the reinforcement project of the dam in Qiqiao River Basin in Gaochun District, Nanjing. With its reliable performance, flexible transition, exquisite body and other advantages, excellent drilling and cooperation for dam reinforcement has become the first choice

the total length of the project is about 4.2km. The clay cut-off wall is punched and grabbed with a hole spacing of 0.92M and a wall depth of 5.5m-9.5m. The specific construction is to use Taixin's rotary drilling rig to drill a hole with a diameter of 1.1m and a depth of 9.5m, then backfill with soil, tamp with a tamper, and drill a hole every other meter. After a section of the dam is tamped, drill the place between the two holes again, and drill two rows after the hole is set. This time, Taixin called two sets of kr50 and one set of kr80 to participate in the construction through the enterprise customer network. Due to the decline of performance

in the combination project of new and old embankments, the biggest difficulty encountered is that the embankment body is reinforced, the filling operation surface is narrow, the soil layer is soft and has a certain slope, and some sections work under the high-voltage line. However, Taixin small rotary excavation is handy for this project. Kr50 has 14 piles 8 hours a day and kr80 has 16 piles 8 hours a day. So far, the project has been carried out as planned

with the continuous popularization of rotary excavation method, rotary drilling rigs can be seen everywhere in various engineering projects. However, in recent years, as the state has vigorously urged the development and transformation of the plastic recycling granulator industry, while exploring industrial and civil construction projects, Taixin has also been involved in water conservancy projects. Taixin's determination to become the leader of "domestic first-class, internationally renowned" pile machinery has never stopped. (this article is from Taixin machinery)
