Description

A foundation drilling method and its electric drilling equipment

Technical field

The invention relates to the field of foundation drilling, specifically a foundation drilling method and its electric drilling equipment.

Background technique

Foundation drilling is a soil detection construction technology. Based on the number of hammers required for the steel drill to enter the foundation soil layer, it can detect the hidden structure in the soil layer or roughly estimate the allowable bearing capacity of the soil layer.

In the current prior art, when drilling the foundation, it is necessary to draw the layout of the drilling holes according to the design drawings, and then sprinkle white gray dots on the pay-out holes according to the layout of the drilling holes to use as marks, and then put The electric drilling machine moves to the drilling position, and the piercing hammer of the electric drilling machine is driven by the motor and chain, causing the piercing hammer to reciprocate up and down. During the movement of the piercing hammer, it hammers the drill rod at the bottom, causing the drill rod to The rod is driven into the soil layer. Every time the drill rod is driven into the soil layer 30cm, the worker needs to record the number of hammer blows of the drill hammer on the drill rod. After the drilling of the drill point is completed, the electric drill machine will The drill rod is pulled out from the soil layer, and then the hole from which the drill rod is pulled out is covered and protected to ensure that the hole will not be disturbed by the outside world. After the acceptance of all drill holes is completed, medium sand needs to be poured into the drill holes. Finally Cover the drill holes with lime sand bricks and number them. The drill rod is made of smooth round steel bars with a diameter of 22 to 25 mm. The drill tip is 60°. The length of the drill rod is 2.0m. The drill rod is spaced from bottom to top at intervals. There are notches left at 30cm to facilitate staff recording;

During the foundation drilling process, workers need to ensure the verticality of the steel drill to avoid inaccuracy in data caused by tilt. Before each hammer blow, the weight and shape of the hammer must be checked to ensure that it meets the requirements. Each hammer blow must be maintained Stable to avoid inaccurate data caused by shaking. During the drill process, attention should be paid to protecting the completed base groove to avoid damage. When pulling out, care should be taken not to damage the steel drill and hammer head.

However, during use, after the drill rod is pulled out from the soil layer, soil from the soil layer will adhere to the surface of the drill rod. When drilling is performed next time, the soil adhered to the surface of the drill rod will increase the depth of the drill rod when the drill rod is inserted. The resistance within the soil layer will in turn affect the drilling accuracy; therefore, a foundation drilling method and its electric drilling equipment are proposed to address the above problems.
