In order to solve the technical problems, the technical proposal of the utility model is a single-column double-guide roadway support stable structure, which comprises a column shoe, a hydraulic prop, a guide column and a top beam, the hydraulic prop is arranged on the vertical central line of the upper surface of the column shoe and is fixedly connected with the column shoe, the top end of the hydraulic prop is provided with the top beam which is fixedly connected with the hydraulic prop, the guide columns are arranged on the left side and the right side of the upper surface of the column shoe and comprise a first square tube and a second square tube, the first square tube is positioned on the upper surface of the column shoe, and is fixedly connected with the column shoe, the outer side wall of the first square pipe is provided with the second square pipe, the second square tube is connected with the first square tube in a sliding mode, and the top of the second square tube is fixed to the lower surface of the top beam.
Preferably, the top beam is arranged above the column shoe and is in sliding connection with the column shoe.
Preferably, the hydraulic prop is telescopic.
Preferably, the number of the guide posts is two, and the two guide posts are symmetrical about a vertical center line of the hydraulic prop.
Compared with the prior art, the utility model discloses, possess following beneficial effect:
through having designed two guide posts in a hydraulic prop both sides, the guide post is by interior, two outer square pipes are constituteed, play and increase rigidity and guide effect, column shoes and back timber structure have still been increased, the lifting surface area has been increased, make hydraulic prop atress even from top to bottom, support overall structure's stability has been increased, effectively avoided the support bending, phenomenon such as falling the frame, the potential safety hazard has been got rid of, the bulk strength of this design can effectively strengthen tunnel support stand, make hydraulic prop atress even, difficult emergence damage, make tunnel support can bear bigger pressure, the in-process that moves the frame simultaneously, tunnel support's overall stability and harmony can be guaranteed.
