Abstract

The utility model discloses a prevent roof beam anchor integrated configuration of soft rock tunnel pucking, include the bottom plate and set up a plurality of crossbeams on the floor, it is adjacent link to each other through the longeron between the crossbeam, be provided with the equidistant drilling of arranging of a plurality of on bottom plate and the crossbeam, insert in the drilling and be equipped with the sleeve pipe, the stock is equipped with in the sleeve pipe interpolation, the loading board is equipped with to the stock bottom, inserts the stock and later is in pack slip casting in the drilling, tray and nut are installed in proper order to the upper end that the stock exposes on the crossbeam, crossbeam, longeron and stock form holistic roof beam anchor structure. The utility model discloses middle cross beam, longeron and stock form holistic roof beam anchor structure, and common atress has played the effect of strutting the bottom plate to prevent that the pucking phenomenon from taking place, construction convenience, to strut the effect better, safe practical.

Description

A kind of beam anchor combining structure preventing soft-rock tunnel pucking
Technical field
Tunnel applied technical field in the utility model design coal mining, especially relates to a kind of for preventing the beam anchor combining structure of soft-rock tunnel pucking.
Background technology
Coal mining enters deep, and it is comparatively common that pucking phenomenon occurs in tunnel.There is pucking phenomenon in tunnel, the comparatively serious transport that have impact on tunnel and normal use, impact is kept the safety in production normally.Administer Floor Heave in Roadway and need larger maintenance load, waste of manpower, material resources, maintenance cost is generally higher.The general FLOOR ANCHOR of control for soft-rock tunnel pucking, FLOOR ANCHOR construction process requirement is higher, and operation is comparatively complicated, and service life is not long.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of beam anchor combining structure for preventing soft-rock tunnel pucking that can prevent Floor Heave in Roadway phenomenon from occurring.
For reaching above-mentioned purpose, a kind of beam anchor combining structure preventing soft-rock tunnel pucking of the utility model, comprise base plate and be arranged at the multiple crossbeams on floor, be connected by longeron between adjacent described crossbeam, described base plate and crossbeam are provided with several boring of equidistantly arranging, insert in described boring and sleeve pipe is housed, anchor pole is fitted with in described sleeve pipe, loaded plate is equipped with in described anchor pole bottom, in described boring, injecting cement paste is filled after inserting anchor pole, described anchor pole exposes to upper end tray and the nut successively on crossbeam, described crossbeam, longeron and anchor pole form overall beam anchor structure.
Further, the length of described crossbeam equals span length.
Further, the length of described longeron equals the spacing of wells.
Further, described anchor pole is tension type anchor pole.
The utility model achieves following beneficial effect:
Crossbeam, longeron, anchor pole are formed overall beam anchor structure by this structure, jointly stressed, serve the effect of common supporting base plate, thus prevent pucking phenomenon from occurring, and easy construction, supporting effect are better, safe and practical.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is that the utility model is a kind of for preventing the structural representation of the beam anchor combining structure of soft-rock tunnel pucking;
Fig. 2 is sectional view of the present utility model.
Description of reference numerals: 1-drift section; 2-nut; 3-pallet; 4-crossbeam; 5-base plate; 6-anchor pole; 7-sleeve pipe; 8-injecting cement paste; 9-holes; 10-loaded plate; 11-longeron.
Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
As shown in Figure 1 and 2, a kind of beam anchor combining structure preventing soft-rock tunnel pucking of the utility model, multiple horizontal 4 beams comprising base plate 5 and be arranged on base plate 5, the length of crossbeam 4 equals span length, be connected by longeron 11 between adjacent crossbeam 4, base plate 5 and crossbeam 4 are provided with several boring 9 of equidistantly arranging, the length of longeron equals the spacing of wells, insert in boring 9 and sleeve pipe 7 is housed, anchor pole 6 is fitted with in sleeve pipe 7, loaded plate 10 is equipped with in anchor pole 6 bottom, in boring, injecting cement paste 8 is filled after inserting anchor pole 6, anchor pole 6 exposes to upper end tray 3 and the nut 2 successively on crossbeam 4, crossbeam 4, longeron 11 and anchor pole 6 form overall beam anchor structure.Wherein anchor pole 6 can for being tension type anchor pole.
Implementation step of the present utility model is illustrated below in conjunction with Fig. 1, Fig. 2:
1, play several boring separated by a distance 9 equably downwards at base plate 5 and crossbeam 4, ensure that the spacing of adjacent boring is equal;
2, after accomplishing fluently, in boring, the anchor rod body 6 that loaded plate 10 is equipped with in sleeve pipe 7 and bottom is equipped with in insertion;
3, in boring, injecting cement paste 8 is filled after the body of rod;
4, upper end tray 3, the nut 2 successively exposed on crossbeam of anchor pole, fixes anchor pole;
5, be connected by adjacent crossbeam 4 with longeron 11, crossbeam, longeron, anchor pole form overall beam anchor structure.
6, the length of crossbeam 4 equals span length; The length of longeron 11 equals the spacing of wells; Anchor pole also can be tension type anchor pole.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
