Abstract

The invention relates to an inclined well shaft construction technology. The construction technology comprises a freezing step and is characterized in that the freezing is block freezing, namely a shaft and an arch part are vertically inserted into a freezing pipe to be frozen. The construction technology also comprises a drilling and digging freezing of a shaft bottom-plate, the shaft bottom-plate is put down from a wellhead section to drill, and the direction of drill holes are parallel with the central line direction of a shaft, namely obliquely drilling; and a freezing station is established at a wellhead and is specially used for freezing of the shaft bottom-plate. The inclined well shaft construction technology adopting the technical scheme has the following beneficial effects that through the improved freezing process, the frozen soil quantity at the excavated section of the inclined well shaft can be greatly reduced, and even the excavated section of the shaft cannot generate frozen soil; the construction difficulty, the manpower and the material resources can be greatly reduced; and the construction progress of an inclined well can be greatly speeded up.

Description

A kind of inclines construction technology
Technical field:
The present invention relates to colliery inclines construction technology, relate in particular to a kind of inclines construction technology.
Background technology:
China is the extremely abundant country of coal reserves, and mine construction is the basic premise of coal resources in China exploitation, and good shaft building technology is the input of the minimizing construction fund of degree greatly, can accelerate the paces of mine construction again.
The inclined shaft freezing engineering is meant in the inclines process of construction; For making things convenient for shaft excavation borehole wall surrounding soil or rock are carried out freezing of certain limit; To reduce or to stop that roof and floor in the shaft excavation process caves in or the generation of accident such as permeable, ensure that pit shaft safety passes through caving ground.
China's large-scale capital construction mine main slant pit shaft is adopting existing inclines to freeze technology when showing soil and weathered rocks section; Though this method can ensure shaft construction safety to greatest extent; But a very big drawback is arranged also; It is excessive that is exactly the frozen soil area, caused very big obstacle to shaft excavation.Waste lot of manpower and material resources, caused the pit shaft cost too high, the situation that driving speed is slow excessively.
Summary of the invention:
Goal of the invention: for a kind of technology that reduces the frozen soil amount of inclines excavated section dramatically is provided.
In order to reach as above purpose, the present invention takes following technical scheme: comprise and freeze step, it is characterized in that: said freezing for piecemeal freezes, promptly pit shaft wall, arch are vertically inserted freezing pipe and are freezed.
Further technical scheme of the present invention is: the brill that also comprises the pit shaft base plate digs freezing; It is transferred from the well head section for the employing of pit shaft base plate and drills, and bore direction is parallel with wellbore centre line direction, promptly makes oblique brill; Set up a Freezing Station again at the well head place, specialize in the pit shaft base plate and freeze to use.
Adopt as above the present invention of technical scheme; Have following beneficial effect: so improved freezes technology; Just can reduce the frozen soil amount of inclines excavated section dramatically; Even make the excavated section of pit shaft frozen soil not occur, greatly degree reduces the construction speed of difficulty of construction and manpower and materials, quickening inclined shaft.
Description of drawings:
In order to further specify the present invention, further describe below in conjunction with accompanying drawing:
Fig. 1 is the constructing structure sketch map of background technology:
Fig. 2 is the constructing structure sketch map of invention:
The specific embodiment:
Below in conjunction with accompanying drawing embodiments of the invention are described, embodiment is not construed as limiting the invention:
In conjunction with Fig. 1;
It is that whole pit shaft freeze all is as a whole that original inclines freeze technology; Comprising the pit shaft part of needs driving, is frozen soil all thereby cause the shaft excavation section, blows out and explodes not open; Excavator digs motionless situation; Greatly influence the driving progress of mine, greatly wasted manpower and materials, extremely be unfavorable for the construction of inclines.
In conjunction with Fig. 2;
This measure improves on original freezing method basis, be to reduce the frozen soil area in the tunneling process, and we adopt piecemeal to freeze, and promptly pit shaft wall, arch are vertically inserted freezing pipe and freezed; The pit shaft base plate then adopts transfers (being that the pit shaft base plate is transferred) from the well head section and drills, and bore direction is parallel with wellbore centre line direction, promptly makes oblique brill.So, just need again the well head place to set up a Freezing Station again, specialize in the pit shaft base plate and freeze to use.
This corrective measure is freezed at original inclines to improve on the basis of technology; The technology of freezing after the improvement divides two parts that inclines are freezed; Freezing efficiency can not change; But can farthest reduce the frozen soil amount of shaft excavation section, improve drivage efficiency, reduce drain on manpower and material resources.
Can effectively improve the inclines efficiency of construction, reduce the inclines cost.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the manual just explains principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.

Claims (2)

1. an inclines construction technology comprises and freezes step, it is characterized in that: said freezing for piecemeal freezes, promptly pit shaft wall, arch are vertically inserted freezing pipe and are freezed.
2. a kind of inclines construction technology as claimed in claim 1; It is characterized in that: the brill that also comprises the pit shaft base plate digs freezing; It is transferred from the well head section for the employing of pit shaft base plate and drills, and bore direction is parallel with wellbore centre line direction, promptly makes oblique brill; Set up a Freezing Station again at the well head place, specialize in the pit shaft base plate and freeze to use.
