Trenchless Pipe Bursting Construction Process.
Pipe bursting is a trenchless construction technique used to replace old or damaged pipelines with new ones. The process involves bursting the old pipe with a bursting head and pulling a new pipe into the ground behind it.
The pipe bursting process typically follows the following steps:
1. Excavation: Two small pits are excavated, one at each end of the section of pipe to be replaced.
2. Bursting head installation: A bursting head is attached to the front of the new pipe. The bursting head is a cone-shaped device that is designed to break the old pipe as it is pulled through the ground.
3. Rod installation: A long, flexible rod is inserted into the old pipe. The rod is used to pull the bursting
head and the new pipe through the ground.
4. Pipe pulling: The bursting head and the new pipe are pulled through the ground behind the rod. As the bursting head breaks the old pipe, the new pipe is pulled into place.
5. Backfilling: Once the new pipe is in place, the pits are backfilled and the ground is restored to its original condition.
Pipe bursting is a relatively quick and efficient trenchless construction technique. It can be used to
replace pipelines in a variety of soil conditions,
including hard rock and frozen ground. Pipe bursting is
also a relatively safe technique, as it does not require
any excavation or trenching.

管廊爆破挖施工工艺流程。

管廊爆破挖是一种非开挖施工技术，用于用新管道更换旧管道或损坏管道。

该工艺包括用爆破头爆破旧管道，并在其后面将新管道拉入地下。

管廊爆破施工通常遵循以下步骤：
1. 开挖，在待更换管道段的每端开挖两个小坑。

2. 爆破头安装，将爆破头连接到新管道的前面。

爆破头是一种锥形装置，旨在在被拉过地面时破坏旧管道。

3. 拉杆安装，将一根长而灵活的拉杆插入旧管道中。

拉杆用于将爆破头和新管道拉过地面。

4. 管道拖拽，爆破头和新管道在拉杆后面被拖拽过地面。

当爆破头破坏旧管道时，新管道被拉入到位。

5. 回填，新管道就位后，回填基坑并恢复地面至其原始状态。

管廊爆破挖是一种相对快速且有效的非开挖施工技术。

它可用
于在各种土壤条件下更换管道，包括硬岩和冻土。

管廊爆破挖也是一种相对安全的技术，因为它不需要任何开挖或沟渠挖掘。
