Embodiment Construction

[0021] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention will become clearer and easier to understand.

[0022] In this construction method, the top fixed rhinestone support is divided into external support and internal support. When the hole depth is less than 2 meters, use the external support method to fix the water drilling rig. When the hole depth is greater than 2 meters, the rigidity of the support system is required to increase, so it is more efficient to use the internal support method to fix the drilling rig.

[0023] Referring to the accompanying drawings as can be seen: the top of the present invention fixed water drilling method manual hole-digging pile method is characterized in that it comprises the following steps:

[0024] ① When the hole d...

Abstract

A manual hole pile digging method employing a top-fixing water drilling method comprises the following steps: (1) adopting an outer manual hole pile digging support method when the depth of a hole is less than 2m, and (2) adopting an inner manual hole pile digging support method when the depth of the hole is more than 2m. Explosive blasting construction can be completely replaced by the manual hole pile digging method; bottom fixing is changed into top fixing by proper improvement of a rock core drilling machine; the device fixing time is shortened; the digging efficiency of a foundation is improved, and the manual hole pile digging method can be widely applied to foundation excavation in a rock geological condition. The used device is small in size, light in weight, and low in demands on water, electricity and roads, and can be widely applied to construction of mountainous areas such as mountain areas and gulches with poor traffic conditions. The manual hole pile digging method has great positive effects on safety production, resource conservation and environmental protection. The manual hole pile digging method is an efficient manual drilling method for manual pile digging and hole forming of a rock stratum.

Description

technical field [0001] The present invention relates to the construction method of the artificial hole-digging foundation whose geological condition is rock, more specifically, it is a method of artificially digging hole piles with the top-fixed water drilling method. It belongs to the field of rocky geological foundation construction for power line iron towers, and can also be used for similar foundation construction in other industries. Background technique [0002] For the artificial excavation foundation with rocky geological conditions, explosive blasting is generally used for construction. This construction method requires the use of explosives, so there are certain safety hazards. At the same time, the consumption of explosives is large and the economic cost is large. In addition Externally, it has a negative impact on the engineering characteristics of the foundation and the surrounding environment. In the construction of tower foundations of power lines in mountain...
