Description
Technical field
The present invention relates to a kind of construction of explosion method, specially a kind of quick-fried construction party of complex environment underground engineering Novel drill
Method belongs to Rock Blasting Technology field.
Background technique
During tunnel excavation, the underground engineering constructions such as construction of subway, if encountering ragstone, the country is generally adopted
It is abolished with the mode of bursting work.
In the prior art, one, limited by complicated geological environment and urban ground building, bursting work blasthole is shallow, quick-fried
Broken efficiency is relatively low, needs to spend more manpower and material resources, secondly, excavation facial contour cannot be pre-formed, therefore will lead to
The out break phenomenon of conventional sinking and blasting increases secondary construction rate, is unfavorable for accelerating construction progress, thirdly, excavating rock mass
When, shock wave vibrates big influence neighboring buildings, influences on surrounding enviroment big in explosion rock mass internal communication.
Summary of the invention
The object of the invention is that it is quick-fried to provide a kind of complex environment underground engineering Novel drill to solve the above-mentioned problems
Construction method.
The present invention is through the following technical solutions to achieve the above objectives: a kind of novel construction of explosion of complex environment underground engineering
Method, including following construction procedure:
Step 1 is excavated in the horizontal direction in working face, expands working space；
Step 2, wait excavate around rock mass, it is multiple horizontal long along being bored perpendicular to excavation face direction using L-type drilling technique
Short-bore is bored between adjacent long hole in hole, runs through it in bottom hole realization；
Step 3, successively by the saw rope for saw of restricting pass through it is adjacent run through long hole, cut, in rock mass to be excavated and week
Free face is formed between the rock of side, by repeatedly cutting, perforation free face obtains the contour line of pre- excavated section；
Step 4 is treated and excavates the sinking and blasting that rock mass carries out unglazed blast hole and keyhole.
Preferably, it in order to which the saw rope for saw of restricting successively is run through long hole across adjacent, and then is convenient for cutting,
In the step 2, multiple long holes realize that the bottom between adjacent long hole is passed through by short-bore along rock mass circumferential distribution to be excavated
It wears.
Preferably, in order to reduce the clipping to rock mass, be conducive to bore quick-fried progress, in the step 3, free face is perpendicular to opening
Digging face, and it is consistent with excavated section profile after perforation.
When preferably, in order to preferably resolve underground engineering hard rock mass drill bursting construction under complex environment, vibration is big
The problem for influencing neighboring buildings, in the step 4, the sinking and blasting of unglazed blast hole and keyhole only includes breaking hole.
The beneficial effects of the present invention are: the quick-fried construction method design of the complex environment underground engineering Novel drill is rationally, step 2
In, multiple long holes realize that the bottom between adjacent long hole is run through by short-bore along rock mass circumferential distribution to be excavated, and make it in hole
Bottom is mutually communicated, and the saw rope for saw of restricting successively is run through long hole across adjacent, and then be convenient for cutting, in step 3, is faced sky
Face is consistent with excavated section profile perpendicular to excavation face, and after penetrating through, and is formed between rock mass to be excavated and periphery rock
Free face reduces the clipping to rock mass, is conducive to bore quick-fried progress, and by repeatedly cutting, perforation free face obtains pre- excavated section
Contour line, avoid the out break phenomenon of conventional sinking and blasting, reduce secondary construction rate, in step 4, unglazed blast hole and keyhole
Sinking and blasting, only include breaking hole, excavate rock mass, make shock wave in explosion rock mass internal communication, preferably resolve multiple
Under heterocycle border when underground engineering hard rock mass drill bursting construction, the big problem for influencing neighboring buildings is vibrated.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1~2, a kind of quick-fried construction method of complex environment underground engineering Novel drill, including following construction procedure:
Step 1 expands work along working face horizontal direction excavation according to mechanical scale, human resources and construction design drawing
Make space；
Step 2, around rock mass 102 to be excavated, according to wishing to get excavation face shape, to cut for arc, along perpendicular to excavation
Horixmtal long hole 103,104,105,106,107,108,109 is beaten in face direction respectively, and bore short-bore 201,202,203,204,
205,206,207, it is mutually communicated adjacent long hole；
Step 3 is each passed through long hole 103, short-bore 201 and long hole 104 using the saw rope of rope saw, and is carried out using rope saw
Cutting makes to form a free face between rock mass 102 and rock to be excavated whole 101；
Step 4 is each passed through long hole 104, short-bore 202 and long hole 105 using the saw rope of rope saw, and is carried out using rope saw
Cutting makes to form a free face between rock mass 102 and rock to be excavated whole 101；
Step 5 is each passed through long hole 105, short-bore 203 and long hole 106 using the saw rope of rope saw, and is carried out using rope saw
Cutting makes to form a free face between rock mass 102 and rock to be excavated whole 101；
Step 6 is each passed through long hole 106, short-bore 204 and long hole 107 using the saw rope of rope saw, and is carried out using rope saw
Cutting makes to form a free face between rock mass 102 and rock to be excavated whole 101；
Step 7 is each passed through long hole 107, short-bore 205 and long hole 108 using the saw rope of rope saw, and is carried out using rope saw
