Pier piling method based on crawler type engineering machine

Abstract

The invention relates to a pier piling method based on a crawler type engineering machine. An existing pier ground serves as a supporting face, a crawler type hanging machine and a crawler type piling machine are sequentially arranged on a steel plate laid on the ground of a construction pier, pile bodies are hung, transported and constructed, and therefore the construction of the existing pier is reinforced; the whole design method is clear in logic, the normal work of the pier is kept during construction, the inconvenience caused when a traditional piling ship is driven into pile groups for construction and damage caused to existing pile foundations are effectively avoided; in addition, the whole design method is simple, cost is easy to control, and the construction period and construction quality can be effectively ensured in actual application.

Description

technical field [0001] The invention relates to a wharf piling method based on crawler-type engineering machinery. Background technique [0002] Ports have always played an important role in a country's economic development and are an important link in the transportation system. As the connection point between the domestic market and the international market, it has always been a gathering point for goods, capital, technology, talents, and information. As a hydraulic structure for goods loading and unloading and passenger loading and unloading by the seaside and riverside, the wharf plays an irreplaceable role in the port engineering structure. Once the operation of the terminal stops or the throughput capacity cannot meet the demand, a large amount of goods will be stranded in the port, causing huge economic losses. [0003] During the use of the wharf, the following two problems often occur: (1) Under the action of the impact force of the ship and the load of the upper lo...

Problems solved by technology

Once the terminal stops operating or the throughput capacity cannot meet the demand, a large amount of goods will be stranded in the port, causing huge economic losses

[0003] During the use of the wharf, the following two problems often occur: (1) Under the action of the impact force of the ship and the load of the upper loading and unloading machinery, the pile foundation of the wharf is damaged; (2) The handling capacity of the wharf cannot adapt to the economic development Demand has become one of the bottlenecks in the logistics link

The feature is that it works on water, and it does not affect each other with land operations during the initial construction of the wharf. However, it is greatly affected by hydrological factors such as wind and waves, weather, water level, etc., and the construction period may be extended

In the wharf reinforcement, renovation and repair project, the piling ship cannot flexibly drive into the pile group for operation, which will hinder the normal operation of the wharf and have a negative impact on the stability of the pile foundation

[0006] If it is necessary to realize the reinforcement and transformation of the wharf without affecting the operation of the wharf, the construction difficulty will be increased.

The existing inclined pile construction technology either requires the wharf to stop operations to cooperate with the construction, or needs to use flexible piling equipment so that it can work in the pile group under the wharf to achieve the purpose of piling, which not only affects the normal use of the wharf, but also makes it impossible for goods to be transported in time. Loading, unloading and transshipment will cause economic losses, and the construction period will be extended and economic benefits will be low due to the inconvenience of piling ships in the pile group. At the same time, it will reduce the stability of the pile foundation and cause safety hazards
