Drilling equipment for construction in bridge engineering field

Abstract

The invention discloses drilling equipment for construction in bridge engineering field. The drilling equipment comprises a machine frame body, a vertical balancing mechanism, a vertical correcting mechanism, a drill rod and a supporting foot stool. The inner side of the machine frame body is connected with the vertical balancing mechanism. The vertical balancing mechanism is connected with the drill rod through the vertical correcting mechanism, and the vertical balancing mechanism, the vertical correcting mechanism and the drill rod communicate with one another. The drilling equipment has the beneficial effects that firstly, the horizontal state of the mechanism is in a normal value range through a plane structure of the vertical balancing mechanism, inclination data of the mechanism arejudged according to the inclination degree of a caliper frame so that the vertical and horizontal line angle of the drill rod can be adjusted, according to accurate numeric values obtained through amodifying electrode holder and a correcting vesicle, the machine frame body is further adjusted, so that the drill rod can drill downwards continuously in the mode of being perpendicular to the horizontal line, and the situation that a reinforcing cage cannot be put into the hole after drilling is completed is avoided.

Description

technical field [0001] The invention relates to the field of drilling, in particular to a construction drilling device in the field of bridge engineering. Background technique [0002] With the acceleration of the urbanization process, the connection between urban areas needs to be improved. However, based on the characteristics of the country, the terrain between the areas is high in the southeast, with criss-crossing rivers and rolling mountains. Only through roads can the complex and changeable The terrain is closely connected, and the bridge is an important part of these roads, railways, rural roads and water conservancy construction, and it is also the connection hub for vehicles and pedestrians to cross rivers, valleys and other lines. Therefore, the construction of bridges cannot be ignored, especially in bridge construction. It is necessary to pay attention to prevent the deflection of the bored pile, because once the hole is not vertical and the deviation value is g...

[0002] With the acceleration of the urbanization process, the connection between urban areas needs to be improved. However, based on the characteristics of the country, the terrain between the areas is high in the southeast, with criss-crossing rivers and rolling mountains. Only through roads can the complex and changeable The terrain is closely connected, and the bridge is an important part of these roads, railways, rural roads and water conservancy construction, and it is also the connection hub for vehicles and pedestrians to cross rivers, valleys and other lines. Therefore, the construction of bridges cannot be ignored, especially in bridge construction. It is necessary to pay attention to prevent the deflection of the bored pile, because once the hole is not vertical and the deviation value is greater than the specified requirement, the reinforcement cage cannot enter the hole smoothly. Due to uneven settlement during the process, based on the above premise, this case developed a construction drilling equipment in the field of bridge engineering to solve this problem
