The invention relates to a drilling machine foundation. According to the drilling machine foundation, an elongated groove facing to the ground is arranged on the periphery of freeze holes, the left and the right side walls of the elongated groove are provided with brick walls, and footrest steel plates are arranged on the ground around the elongated groove. The drilling machine foundation is stable in the foundation body, high in drilling quality and low in using cost.
Description
technical field [0001] The invention relates to a drilling rig foundation, in particular to the foundation of an inclined well freezing drilling rig. Background technique [0002] Freezing drilling construction is an important construction process in the early stage of freezing and refrigeration engineering construction. The quality of freezing drilling construction directly affects the quality and economic benefits of the entire freezing project. The drilling rig used in the freezing drilling construction must lay the drilling rig foundation. In the construction of the special drilling freezing method introduced by the former Soviet Union in the 1950s, the drilling rig foundation was rammed and leveled with the notoginseng ash soil, and then laying The sleeper track is not only the foundation of the drilling rig, but also the drilling rig can slide on it. After the 1980s, it was improved to the notoginseng ash soil plus concrete foundation. The disadvantages of both are t...
