Description
Technical Field
The utility model relates to a geology construction technical field specifically is a well stroke ization mudstone geology bores and explodes and bury medicine structure.
Background
Along with city construction is constantly being developed, and underground space constantly deepens, and engineering construction constantly develops to city peripheral area, and the geological environment that meets no longer limits in soft soil texture, meets hard soil layer conditions such as weathering rock stratum and will more and more, and conventional excavation mode has two points to be not suitable for under apoplexy argillite geological conditions: firstly, the mudstone hardness sticks between soil and rock, the excavator is difficult to directly excavate, but a fracture zone cannot be formed during crushing due to insufficient hardness when the pickaxe is crushed; secondly, as the mud rock soil can not form an effective fracture zone when the pickaxe is crushed, the distance between crushing points can only be reduced, so as to facilitate the excavation of a subsequent excavator, the mechanical workload of the pickaxe is greatly increased, the mechanical investment is large, the construction period progress is also severely restricted, the construction requirements are difficult to meet, and particularly, the construction site with a large amount of excavation individuals and large earth volume is constructed; thus, the existing use requirements are not satisfied.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a well stroke ization shale geology is bored and is exploded medicine structure of burying to solve the problem among the prior art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a well stroke ization mudstone geology bores and explodes and buries medicine structure, includes blasting region, medium-length hole big gun hole, first section and the foundation ditch isolation hole of packing in the foundation ditch, the foundation ditch isolation hole has all been seted up to the edge all around of blasting region in the foundation ditch, the medium-length hole big gun hole has been seted up in the blasting region in the foundation ditch, the medium-length hole big gun hole includes that first charge section, second pack section and second charge section, first charge section, second pack section and second charge section from the top down and set gradually.
Preferably, the first and second plug sections are plugged with sand clay.
Preferably, the hole distribution mode of the medium-length hole blast holes adopts quincunx hole distribution.
Preferably, every two adjacent foundation pit isolating holes are mutually connected.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model is suitable for the construction site which has hard soil, slightly weathered and moderately weathered argillaceous strata, can not normally operate without processing an excavating machine, has more bearing platforms, deep depth and large excavated earth volume; the utility model discloses an excavation mode that blasting breakage, excavator excavation combined together is compared, is compared with the smooth blasting with direct blasting: the key point of the utility model is that the soil body to be blasted is isolated from the surrounding soil body through the isolation hole, so as to prevent the blasting vibration wave from influencing the integrity and stability of the surrounding soil body, avoid the situation that the surrounding soil body needs to be replaced by the soil body, reinforce the soil body and the like due to the blasting vibration damage, and effectively control the excavation size of the foundation pit through the isolation hole, avoid the over-excavation treatment or the secondary excavation removal with less time, greatly accelerate the working progress and reduce the mechanical investment; the utility model abandons single blasting mode (such as common blasting and smooth blasting), adopts the mode of isolating firstly and then blasting, and simply and directly performs blasting, thus the blasting influence range can not be effectively controlled, and the cost of secondary treatment can be increased more or less; and use smooth blasting, because of the restriction of the mud rock stratum all around to the blasting scope, blasting vibration energy does not have an effective release face, through many times of experiments, the blasting effect is superior to ordinary blasting effect, but still not as good as the effect that bores and explodes the combination, and smooth blasting expense is higher than ordinary blasting far away simultaneously.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-2, in the embodiment of the utility model, a well gasification shale geology bores and explodes and buries medicine structure, blasting regional 1 in the foundation ditch, medium-length hole big gun hole 2, first section 201 and foundation ditch isolation hole 3 are packed, blasting regional 1 in the foundation ditch edge all has seted up foundation ditch isolation hole 3 all around, blasting regional 1 in the foundation ditch has seted up medium-length hole big gun hole 2, medium-length hole big gun hole 2 includes first charge segment 202, section 203 and second charge segment 204 are packed to the second, first charge segment 202, the second is packed section 203 and second charge segment 204 and sets gradually from the top down, first section 201 and the second of packing are packed to adopt the sand clay to pack, the hole distribution mode of medium-length hole big gun hole 2 adopts plum blossom shape cloth hole, foundation ditch isolation hole 3 links to each other between two liang adjacently.
The utility model discloses a theory of operation is: when the weathering mudstone geological drilling explosion is carried out, the rotary drilling rig drills a circle of foundation pit isolation holes 3 around the foundation pit along the side line of the foundation pit placed by a measuring tool, the adjacent drilling of the foundation pit isolation holes 3 is ensured to be connected, so that the blasting area 1 in the foundation pit is isolated, and the blasting area 1 in the foundation pit is ensured to be not influenced on the peripheral soil body of the foundation pit during blasting to the maximum extent; the utility model discloses an excavation mode that blasting breakage, excavator excavation combined together is compared, is compared with the smooth blasting with direct blasting: the key point of the utility model is that the soil body to be blasted is isolated from the surrounding soil body through the isolation hole, so as to prevent the blasting vibration wave from influencing the integrity and stability of the surrounding soil body, avoid the situation that the surrounding soil body needs to be replaced by the soil body, reinforce the soil body and the like due to the blasting vibration damage, and effectively control the excavation size of the foundation pit through the isolation hole, avoid the over-excavation treatment or the secondary excavation removal with less time, greatly accelerate the working progress and reduce the mechanical investment; the utility model abandons single blasting mode (such as common blasting and smooth blasting), adopts the mode of isolating firstly and then blasting, and simply and directly performs blasting, thus the blasting influence range can not be effectively controlled, and the cost of secondary treatment can be increased more or less; and use smooth blasting, because of the restriction of the mud rock stratum all around to the blasting scope, blasting vibration energy does not have an effective release face, through many times of experiments, the blasting effect is superior to ordinary blasting effect, but still not as good as the effect that bores and explodes the combination, and smooth blasting expense is higher than ordinary blasting far away simultaneously.
