Abstract
The invention discloses a water-mill drilling construction process for Karst terrains, relates to the technical field of construction engineering, and aims to solve the technical problems in the conventional basal hole drilling process for hard rock foundations, such as difficulty in breaking hard rock, slow construction progress, large noise and poor basal hole forming effect. The water-mill drilling construction process for Karst terrains comprises the following steps of: (a) according to the position and size of a target hole, marking a peripheral line and two mutually-perpendicular diameter lines of the target hole on a ground surface required for construction; (b) performing core-drilling operation along the peripheral line of the target hole; (c) repeating the step (b) until all the core-drilling operations along the peripheral line of the target hole is completing completed; (d) performing core-drilling operation along the two diameter lines formed in the step (a) in the same way as the steps (b) to (c), and ensuring that the central axis of a drill tube is perpendicularly crossed with the diameter lines; and (e) crushing and removing stones in the target hole.
Description
Technical field
The present invention relates to construction engineering technical field, particularly a kind of hard karst landform water mill of basic rock that is applied to bores construction technology.
Background technology
In the karst landform district, basic rock is hard, carries out datum hole excavation in this type of area and adopts dual mode usually, and one is slow for adopting pneumatic pick to carry out datum hole excavation progress, and big degree of depth perforate is then more difficult; It is bigger to the destruction of hole wall two for adopting bursting work, is not suitable for the effect of many places pore-forming in the small size, and influence is bigger between the adjacent datum hole.
Carrying out the datum hole excavation with pneumatic pick is example, and the principle of its construction is that diesel compressor is the pneumatic pick power source, rotates broken stone by air compression impelling pneumatic pick drill bit; Processing step is: preparation of construction, and------the broken stone of pneumatic pick smashes the cubic meter of stone in the hole, and---it is broken again that the dark cubic meter of stone of every broken 300mm is cleared a hole slag---cleans datum hole to measure unwrapping wire (location and sideline); The shortcoming that this technology exists is that foundation stone is hard just very difficult broken, and progress is slow, and noise is big, and is bigger to the destruction of hole wall, is not suitable for the harder cubic meter of stone.
Summary of the invention
The present invention be intended to solve in the hard datum hole drilling construction technology of traditional basic rock exist be difficult to broken solid rock, technical problems such as construction speed is slow, noise is big, datum hole forming effect difference, with provide have can the efficiency crushing solid rock, the karst landform water mill brill construction technology of good, the construction control precision height of datum hole forming effect, advantages such as construction speed is fast, noise is little.
The objective of the invention is to be achieved through the following technical solutions.
Karst landform water mill of the present invention bores construction technology, comprises the steps:
A) position and the size according to target hole calibrates the target hole outer peripheral lines on the face of land that need are constructed, and is that intersection point calibrates two orthogonal diameter lines with the center of circle of target hole;
B) bore the core operation along above-mentioned target hole outer peripheral lines: bore tube and be placed on the guide rail that is vertically to the face of land, the central axis and the target hole outer peripheral lines of boring tube intersect vertically, and brill tube upper end connects motor, and the delivery port of water pipe is communicated with the brill tube inner chamber; Motor drives is bored tube and is bored movingly during operation, and water is annotated in boring tube inner chamber via water pipe simultaneously, when bore tube down drilling depth reach when boring tube length and spending, mention and bore tube, will bore tube, motor and water pipe and move to next target outer peripheral lines brill core job position;
C) repeating step b bores the core operation until all that finish along the target hole outer peripheral lines;
D) the brill core operating type of employing step b～c bores the core operation along two diameter lines described in the step a, and the central axis and the diameter line that bore tube during operation intersect vertically;
E) broken and clear stone in the target hole.
Karst landform water mill of the present invention bores construction technology, uses chisel and pneumatic pick to impact stone in the target hole from side among the wherein said step e, makes the broken apart one-tenth fritter of stone in its hole.
Karst landform water mill of the present invention bores construction technology, after wherein said step e finishes target hole is picked dozen finishing.
Karst landform water mill of the present invention bores construction technology, and wherein said brill tube diameter is 50mm, or 100mm, or 150mm, and boring barrel thick is 6mm, and boring the tube length degree is 500～700mm.
Karst landform water mill of the present invention bores the beneficial effect of construction technology:
1. at karst landform solid rock efficiency of construction height, average advance can reach 100cm/ days, and progress is fast;
2. it is little to use water mill to bore noise, is beneficial to environmental protection;
3. the construction of water mill brill also has the precision height, periphery and hole wall is influenced characteristics such as little,, in 10mm hole wall and adjacent datum hole is not almost influenced for center line, limit, hole size Control precision.
The specific embodiment
Detailed structure of the present invention, application principle, effect and effect are illustrated by following embodiment.
Karst landform water mill of the present invention bores construction technology, comprises the steps:
A) position and the size according to target hole calibrates the target hole outer peripheral lines on the face of land that need are constructed, and is that intersection point calibrates two orthogonal diameter lines with the center of circle of target hole;
B) bore the core operation along above-mentioned target hole outer peripheral lines: bore tube and be placed on the guide rail that is vertically to the face of land, the central axis and the target hole outer peripheral lines of boring tube intersect vertically, and brill tube upper end connects motor, and the delivery port of water pipe is communicated with the brill tube inner chamber; Motor drives is bored tube and is bored movingly during operation, and water is annotated in boring tube inner chamber via water pipe simultaneously, when bore tube down drilling depth reach when boring tube length and spending, mention and bore tube, will bore tube, motor and water pipe and move to next target outer peripheral lines brill core job position;
C) repeating step b bores the core operation until all that finish along the target hole outer peripheral lines;
D) the brill core operating type of employing step b～c bores the core operation along two diameter lines described in the step a, and the central axis and the diameter line that bore tube during operation intersect vertically;
E) use chisel and pneumatic pick to impact stone in the target hole, make the broken apart one-tenth fritter of stone in its hole, and clear stone in the target hole from side;
F) target hole is picked dozen finishing.
Above-mentioned technological process can be reduced to: preparation of construction, and------around the datum hole and middle part original position is bored core---gets core and smashes the cubic meter of stone hole in that------picking at the bottom of perforated wall and the hole the unnecessary cubic meter of stone---repeats to bore core and get core---and clean datum hole to clear the datum hole cubic meter of stone and hole slag to measure unwrapping wire (location and sideline).
