Embodiment Construction

[0070] The present invention will be further described below in conjunction with drawings and embodiments.

[0071] For vertical drilling, it is also possible to adopt the method and some devices of the present invention, which is also the technical scope claimed by the present invention.

[0072] exist figure 1 In the shown embodiment, according to the size of the drilled hole, the requirements of drilled hole torsion and power are met, and at the same time, the manufacturing accuracy of the equipment and the assembly accuracy with the feed guide rail should be high, so as to reduce the assembly of the equipment itself. The impact of errors on drilling accuracy, the DD-750HY hydraulic diamond drilling machine produced by HILTI in Liechtenstein is selected to be equipped with D-LP32 hydraulic power system; combined with self-designed and improved long guide rails 17 and the adjustable frame 18, together with relevant special auxiliary tools and accurate measurement and monito...

Abstract

The invention relates to a method for processing high accuracy horizontal drilling on the concrete and relative device. The method comprises: selecting power and auxiliary device; according to the size and depth of drill hole, selecting the grade of drill device and drill head; selecting the diamond drill head; mounting and regulating the drill frame; presetting the ideal drill hole axes track; selecting and regulating the measuring device; designing and using the dig and guide corrector; matching the drill parameters as drill pressure, rotational speed and the pump amount; and when the drill hole axes inclined degree is over the standard, process correction and bidirectional drill method. Wherein, the adjustable frame, the hole guide corrector fixed on one end of frame and the diamond drill device are fixed on the steel beam of said frame; the base of said frame via four thread rods whose heights are adjustable are fixed on the ground; a horizontal adjustable thread rod is arranged between the base and the steel beam; the hole guide corrector is fixed on one end of steel beam, while the drill rod is through its limit hole; and the limit hole and the drill rod have clearance fit. The invention has high accuracy.

Description

technical field [0001] The invention relates to a horizontal drilling method and device used in civil construction, in particular to a high-precision horizontal drilling construction method and device on reinforced concrete. Background technique [0002] Although the drilling equipment in the existing civil engineering industry can complete the drilling operation, the drilling accuracy is not high. In operation, if the drill bit encounters steel bars or extremely hard materials, the deflection rate will be large. It is still possible for ordinary civil construction requirements, but it cannot meet the requirements for some special projects. [0003] At present, in iron and steel enterprises, in order to achieve rapid overhaul of blast furnaces, the concrete foundation of the entire boiler (generally about Φ20m in diameter and 4-5m in height) needs to be cut and separated as a whole. In order to realize the installation of cutting ropes, high-precision horizontal holes must ...
