Dam pile driving method

Abstract

The invention discloses a dam pile driving method. The dam pile driving method is used for driving fixing piles for damming into a dam and comprises the following steps that (1) a pile driving area isselected near a dam opening; (2) a pile driver is moved to be near the pile driving area of the dam; (3) a water flow sensor and an ultrasonic detector arranged on a pile support of the pile driver are placed into the dam opening, water flow and terrains in the dam opening are detected, and the optical water inlet position and / or angle generated by impact of water flow to the fixing piles is calculated through a control device; and (4) the fixing piles for damming are driven into the pile support on the pile driver, and the fixing piles are locked through a locking device on the pile support.By means of the pile driving method, the piles can be driven not only vertically but also obliquely in various directions, so that the driven fixing piles accord with the water flow direction, impactof the water flow to the fixing piles is relieved, the pile driving efficiency and quality are improved, operation is simple, using is convenient, and implementation and popularization are facilitated.

Description

technical field [0001] The invention relates to a using method, in particular to a method for driving dam piles. Background technique [0002] my country is one of the countries with frequent and serious flood disasters in the world. According to statistics, the economic losses and casualties caused by flood disasters in our country rank first among all kinds of natural disasters. Floods occur frequently, spread widely, come fiercely, and are extremely destructive. Floods not only inundated houses and people, causing a large number of casualties, but also swept away people's property and flooded farmland, destroying crops, resulting in a significant reduction in food production, resulting in famine. Floods can also damage factories, communication and transportation facilities, thereby causing damage to the national economy. [0003] When a flood occurs, in order to prevent the disasters brought by the flood to people, people will take measures to build a dam to stop the f...

Problems solved by technology

Floods not only inundated houses and people, causing massive casualties, but also swept away people's property and flooded farmland, destroying crops and causing a drastic reduction in food production, leading to famine

Floods can also damage factories, communication and transportation facilities, thereby causing damage to the national economy

[0003] When a flood occurs, in order to prevent the disasters brought by the flood to people, people will take measures to build a dam to stop the flood, and the dam usually needs to drive piles at the mouth of the dam. However, when people drive piles, they usually set the fixed piles vertically When driving into the water, because the speed of the water flow and the situation at the bottom of the water are not known, the fixed piles driven into the dam mouth are often not at the predetermined position, and the desired effect cannot be achieved. Not only the fixed piles are wasted, but also a waste of time. When the pile is put into the water, the impact of the water flow on the fixed pile can shift the fixed pile from its original position. In serious cases, even the pile driver will also shift with the fixed pile, which brings a lot of inconvenience to the flood control
