Description
Technical field
The utility model belongs to engineering technology, and in particular to the supporting construction of bad geological section in a kind of hole.
Background technology
In in-cavity construction, usually because of the geological conditions that can not be met, such as tomography, weak structural face bad geological section,
Cause the landslide of crown and side wall.During sump remedy, often there is the phenomenon of one side supporting one side chip off-falling, especially mixed
Coagulate in native course of injection, loose due to sillar comes off, it is difficult to accomplish to spray mixed closing, both brought difficulty to supporting follow-up, and gave again
The safety belt of workmen carrys out hidden danger.
Utility model content
In view of the above-mentioned problems, the utility model aims to provide a kind of supporting construction of bad geological section in hole, can accelerate
Supporting progress, ensure supporting quality, and can prevents landwaste from coming off, ensures workmen's safety.
The utility model solve problem technical scheme be：The supporting construction of bad geological section in a kind of hole, including set
Steel arch-shelf below cavern's landslide section, unfavorable geology position is covered with supporting plate in hole, between supporting plate and steel arch-shelf
Provided with support bar, the support bar one end is fixedly connected with supporting plate, the other end is fixedly connected with steel arch-shelf；
The concrete layer by unfavorable geology position and supporting plate closing is coated with supporting plate region；
Concrete is filled with space between steel arch-shelf and cavern's inwall.
Specifically, the supporting plate is steel plate, support bar is steel pipe, and support bar welds with steel plate and steel arch-shelf.
Preferably, encrypt and set between the Pin and Pin of the steel arch-shelf, spacing is 30cm~50cm.
Construction procedure is：
1st, unfavorable geology position is pasted using steel plate；
2nd, steel plate is lived with steel pipe support, and steel pipe bottom is stuck at the top of steel arch-shelf, and firm welding；
3rd, the steel plate gunite concrete at unfavorable geology position is closed；
4th, fill concrete in the space between steel arch-shelf and cavern's inwall；
5th, other supportings are carried out.
The utility model uses the timely block of supporting plate, ensure that the progress and quality of supporting, ensure that workmen's
Safety.Construction is simple, device therefor is all cavern con struction common equipment, without extra equipment investment.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is elevational schematic view；
Fig. 2 is schematic three dimensional views.
In figure：1- steel arch-shelfs；2- unfavorable geologies position；3- supporting plates；4- support bars；5- caverns.
Embodiment
As shown in Fig. 1~2, the supporting construction of bad geological section in a kind of hole, including be arranged on below the landslide of cavern 5 section
Steel arch-shelf 1.Encrypt and set between the Pin and Pin of the steel arch-shelf 1, spacing is 30cm~50cm.
Unfavorable geology position 2 is covered with supporting plate 3 in hole, and support bar 4 is provided between supporting plate 3 and steel arch-shelf 1.Should
The one end of support bar 4 is fixedly connected with supporting plate 3, the other end is fixedly connected with steel arch-shelf 1.
The concrete layer for closing unfavorable geology position 2 and supporting plate 3 is coated with the region of supporting plate 3.
Concrete is filled with space between steel arch-shelf 1 and the inwall of cavern 5.
The supporting plate 3 is steel plate, and support bar 4 is steel pipe, and support bar 4 welds with steel plate and steel arch-shelf 1.
Construction procedure is
1st, unfavorable geology position 2 is pasted using steel plate；
2nd, steel plate is lived with steel pipe support, and steel pipe bottom is stuck in the top of steel arch-shelf 1, and firm welding；
3rd, the steel plate gunite concrete at unfavorable geology position 2 is closed；
4th, fill concrete in the space between steel arch-shelf 1 and the inwall of cavern 5；
5th, other supportings are carried out.
