Problems solved by technology

[0004] The existing rotary excavator needs to move to the next drilling position as a whole after completing a hole, and needs to be re-aligned every time it moves, which will undoubtedly reduce the construction efficiency
[0005] Moreover, the existing rotary excavator can only drill one hole at a time, and the efficiency needs to be improved
[0006] In addition, at present, during bridge construction, it is usually necessary to build a construction access road to carry out the construction of the pile foundation and cap, and the construction of the construction access road will cause greater damage to the environment, and at the same time have a greater impact on wild animals and plants under the bridge

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] Such as figure 1 , 2 , 3, the rotary drilling rig for fishing construction disclosed by the present invention includes a rotary drilling body 2, a support frame and a traversing drive mechanism for driving the rotary drilling body 2 to move horizontally. The support frame is provided with horizontal slide rails, and the rotary drilling drill body 2 is slidingly connected with the horizontal slide rails. The lateral displacement of the rotary drilling drill body 2 can be realized by driving the rotary drilling drill body 2 to move horizontally and linearly through the traversing drive mechanism, thereby realizing Quickly form holes in different positions.

[0040] In this embodiment, the support frame includes a base 1 and a door frame 9, the bottom of the...

Abstract

The invention relates to a rotary drilling rig for angling method construction and a using method thereof, and belongs to the technical field of foundation construction equipment. The rotary drillingrig comprises two rotary drilling rig bodies, a support frame and a transverse movement driving mechanism for driving the rotary drilling rig bodies to move horizontally, wherein the rotary drilling rig bodies are in sliding connection with horizontal sliding rails on the support frame, the support frame comprises a base and a portal frame, water-permeable pile casings are movably arranged on thelower portion of power heads of the rotary drilling rig bodies, and when drilling rods descend, the water-permeable pile casings are driven to descend. According to the rotary drilling rig, the rotaryexcavating drill bodies can be transversely moved and displaced, the hole forming position can be changed without moving the support frame, and the construction efficiency can be improved; during construction, the two rotary drilling rig bodies work simultaneously, so that the construction efficiency can be improved by more than two times; permeable pile casings are adopted for protecting walls,and clear water construction method is adopted, and the underground water quality of the surrounding environment is not influenced; and the rotary drilling rig is particularly suitable for a bridge crane angling method and a trestle lateral angling method without constructing a ground construction sidewalk, the construction environment can be protected, and damage to the environment can be reducedto the maximum extent.

Description

technical field [0001] The invention relates to the technical field of foundation construction equipment, in particular to a rotary drilling rig for fishing construction and a use method thereof. Background technique [0002] Rotary excavator is a kind of comprehensive drilling rig, which can use a variety of bottom layers, and has the characteristics of fast hole forming speed, less pollution, and strong mobility. The short auger bit is used for dry excavation, and the rotary bit can also be used for wet excavation in the case of mud protection. The rotary excavator can cooperate with the hammer to drill the hard stratum and carry out the hole digging operation. If it is matched with the expansion head drill, the hole reaming operation can be carried out at the bottom of the hole. [0003] Fishing method construction is a commonly used construction method, including bridge machine fishing method, trestle side fishing method and so on. [0004] The existing rotary excavat...
