Description

Technical Field

[0001] This utility model relates to the field of highway bridge deck construction, and in particular to a device for drilling drainage holes in highway bridge decks. Background Technology

[0002] The drainage system of highway bridges is one of the key links in ensuring the structural safety and traffic safety of bridges. The drainage holes on highway bridges can remove water from the bridge surface in a timely manner, prevent water accumulation from corroding the bridge structure, and extend the service life of the bridge. During the construction of highways, vertical drainage holes are sometimes added as needed. Some existing drilling methods, such as manual hand-held water drills, involve workers placing the water drill base directly on the bridge surface to drill holes. The water drill base is not effectively fixed, and its stability depends entirely on the experience and physical strength of the operator. Alternatively, workers can use expansion bolts to fix the water drill base to the bridge surface, but the expansion bolts need to be treated later, which greatly affects the drilling efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a drilling device for drainage holes on highway bridge decks that is simple in structure and easy to use. It can stably install water drilling machines and can be easily moved and fixed, effectively improving the construction efficiency of drainage holes.

A pair of mounting vertical rods are provided on the top of the mounting blocks. Inverted L-shaped lifting struts are provided around the mounting vertical rods on both sides of the mounting blocks. A guide sleeve is provided at one end of each inverted L-shaped lifting strut. The guide sleeve is located around the mounting vertical rod. A pressure plate is provided at the other end of several inverted L-shaped lifting struts through a connecting vertical rod. The pressure plate abuts against the outside of the concrete guardrail.

[0007] The mounting block has threaded holes at both ends, and a lower limit bolt is installed in the threaded hole. The end of the lower limit bolt passes through the threaded hole and abuts against the inside of the concrete guardrail.

[0008] The base of the water drill is mounted on the concave base plate;

[0009] Preferably, the drill barrel of the water drill never overlaps with the orthographic projection of the concave base plate, thus enabling normal drilling on the bridge deck.

The inverted L-shaped lifting struts rest against the top of the concrete guardrail. The concave base plate is moved horizontally according to the position of the drilled holes. After moving to the designated position, the lower limit bolt is rotated so that its end rests against the concrete guardrail. Then, the upper limit bolt is rotated so that its end rests against the concrete guardrail, thus completing the limiting and fixing of the support frame. Afterward, the position of the water drill base is adjusted back and forth according to the position of the drainage hole. The water drill base is then fastened to the concave base plate with the fastening nut, completing the installation. After installation, the worker steps on the concave base plate with both feet and uses the water drill to drill holes.

[0016] The beneficial effects of this utility model are: simple structure and easy to use. On the one hand, it can form a stable installation for the water drilling machine, and on the other hand, it can be easily moved and fixed, effectively improving the construction efficiency of the drainage hole.
