Abstract
The present invention relates to a kind of rig basis.At the oriented underground elongated slot of freezing hole periphery, the left and right sidewall of elongated slot there is masonry walls, the ground of described elongated slot periphery is covered with foot-operated steel plate.Its basis is steady, drilling quality is high, and use cost is low.
Description
Technical field
The present invention relates to a kind of rig basis, the particularly basis of inclined shaft freezing boring drill.
Background technology
Freezing borehole construction is the important working procedure freezing Refrigeration Engineering construction early stage, and the quality of freezing borehole construction quality directly affects quality and the economic benefit of whole freezing engineering.The rig used in freezing borehole construction must lay rig basis, in the special sinking shaft construction freezing method that eighties of last century the fifties is introduced by the former Soviet Union, freezing borehole is constructed, rig basis for 37 lime earth rammed levelling after, lay pillow rail, be rig basis, rig can slide above again.After the eighties, be improved to 37 lime earth add concrete foundation.Both defects are that cost is high, the engineering time long, remove difficulty greatly, time-consuming.Particularly in inclined shaft freezing drilling construction, the boring of construction is more shallow, and the 37 lime earth of rig adds concrete foundation horizontal range speciality.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of rig basis, its basis is steady, drilling quality is high, and use cost is low.
The present invention solves the technical scheme that its technical problem takes: at the oriented underground elongated slot of freezing hole periphery, the left and right sidewall of elongated slot has masonry walls, the ground of described elongated slot periphery is covered with foot-operated steel plate.
The present invention has following advantages: 1), rig constructs steadily on steel plate basis; 2), occur that drilling slurry retaining wall is bad and step on sky phenomenon after, because the globality of steel plate is fine, there will not be rig crooked, improve drilling construction quality; 3), drilling-machine shifter time, resistance is little, and speed is fast; 4), civilized construction environment is good; 5) environment pollution and waste discharge, is decreased; 6), foot-operated steel plate can recycle, and greatly reduces use cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this present invention is further illustrated.
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention.
Detailed description of the invention
As shown in Figure 1, 2, at the oriented underground elongated slot 4 of freezing hole 5 periphery, the left and right sidewall of elongated slot 4 there is masonry walls 3, the ground of described elongated slot 4 periphery is covered with foot-operated steel plate 2.
The ground on the limit, top of described elongated slot 4 is covered with auxiliary steel plate 6.
Described foot-operated steel plate 2 is of a size of long 12m, wide 2m, thick 25mm.
The size of described auxiliary steel plate 6 is identical with foot-operated steel plate 2.
Claims (3)
