There is a drilling rig platform above the beam, and the drilling rig platform is composed of horizontally erected square wood. And the distance between the adjacent square wood is 0.8 meters, there is no square wood above the drilling makeup, and it is reinforced on both sides of the makeup position. The drilling rig walking bar is fixed on the top of the drilling rig platform by the nails, and there is a sleeve above the drilling makeup. It is in the shape of two coaxial circular tubes, the upper and the lower. There is a 5 cm gap between the sleeve and the drilling makeup, and the gap is filled with burlap and clay.

Preferably, the log makeup of the described manufacturing wooden makeup rack is 5-7 meters long, and the small head diameter is not less than 10 centimeters.

Preferably, the section of the square wood of the described manufacturing drilling rig platform is the square of 20 * 20 centimeters.

[0007] Preferably, the sleeve is made of a steel plate with a thickness of 0.4 centimeters, and the upper height of the sleeve is more than twice the height of the lower part.

The beneficial effect of adopting above technical scheme is: the wooden makeup rack of this bridge construction drilling platform is made up of some log makeups that are driven into both sides of the drilling hole, and the top of the wooden makeup rack is provided with a beam, and the beam is 6 For rice wooden makeup, the beam and the wooden makeup rack are connected by 4-6 nails. There is a drilling rig platform above the beam. The drilling rig platform is composed of square wood erected horizontally, and the distance between adjacent square wood is 0.8 meters. The drilling rig is fixed with the walking bar of the drilling rig, and there is a sleeve above the drilling makeup. The sleeve is in the shape of two coaxial circular tubes, the upper and the lower. The drilling platform creatively uses the wooden makeup rack as a bracket to build the drilling rig platform , and cooperate with the sleeve, install the drilling rig on the drilling rig platform, and carry out construction work on the drilling makeup. When drilling, first make slurry at a slow speed, then use a small mud pump to extract the mud, and then use a large mud pump to remove the sedimented mud. It is driven into the drilling hole for circulation, with high work efficiency and good safety.
