With the development of our country's economy, the speed of urban construction far exceeds the construction of infrastructure. Many cities become rivers as soon as it rains, and the underground pipeline network in cities is a major challenge facing our country. Each city operates independently without unified planning, resulting in chaos in the underground pipeline network.
In addition to the construction of subways in first and second tier cities, many existing underground pipelines need to be diverted. Therefore, pipe jacking construction will definitely become a hot project in urban infrastructure construction in the next decade. Vigorously developing pipe jacking construction equipment and supporting auxiliary equipment will greatly help improve the efficiency of pipe jacking construction.
Below is an analysis of the cranes that must be used in current pipe jacking operations:
In the current pipe jacking construction, the main crane required is to lift the excavation head. This equipment weighs 10 tons, and larger ones weigh around 18 tons. Without a large crane, construction cannot be carried out. The top pipe needs to be lifted step by step from the ground and unloaded from the pipe transport truck. The crane needs to be on the construction site for a long time. Cannot leave.
According to on-site investigation, there are generally three types of cranes with a capacity of 16-20-25 tons, with rental prices ranging from 1000-1200 yuan per day, and the construction party's oil is also required. The construction party also has to be responsible for the food and accommodation of the crane driver, which is also a considerable expense. The comprehensive cost is that the construction party needs to pay the cost of the crane for one month, which is around 30000 to 40000 yuan.
3. The construction site has electricity, but due to the crane, it is not possible to use electricity for operations and can only burn oil. Generally, the first party does not charge the construction party for electricity.
In summary, if there is a crawler crane that can adapt to the construction site and has a good cost performance ratio, it will solve all the above problems at once. Crawler walking is superior to crane tire walking. Crawlers can travel in muddy and uneven construction sites without blind spots, which can solve the problem of long lifting distances and enable crawler cranes to exert greater lifting performance.
Wireless operation ensures safety. The lifting process is carried out by a motor with a pump, without the need for oil burning, and the saved diesel costs are also considerable. For one year's rent of the crane, one can purchase a crawler crane. The construction party of the crane's property rights can serve for more than ten years, and the saved costs can be imagined.
