Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the roadway reservation structure of the utility model comprises a cushion layer 1 laid on the ground of a roadway 4, wherein the cushion layer 1 is composed of a plurality of logs arranged side by side; placed passageway 2 on the bed course 1, passageway 2 is connected gradually by a plurality of cylindric prefabs and forms, is equipped with many stulls 5 between the both sides of passageway 2 and the both sides wall of tunnel 4 respectively, is equipped with many erects to prop 6 between the top of passageway 2 and the 4 tops in tunnel.
The cross braces 5 and the vertical braces 6 are both made of wood.
As shown in fig. 2 and 3, the prefabricated member in the tunnel reservation structure of the present invention includes four arc-shaped templates 11, and the four templates 11 form a cylindrical structure; the two end faces of the template 11 are respectively welded with arc-shaped first connecting pieces 7 shown in fig. 4, and the two side walls of the template 11 are respectively welded with second connecting pieces 9 shown in fig. 5.
The first connecting piece 7 and the second connecting piece 9 are both made of angle steel. The form 11 is a steel product.
The first connecting piece 7 comprises an arc-shaped first connecting piece body 14, a plurality of first through holes 12 are processed on one wing plate of the first connecting piece body 14, and the first connecting piece body 14 is fixedly connected to the end face of the template 11 through a plurality of bolts 10 and then welded. The second connecting piece 9 comprises a second connecting piece body 15, a plurality of second through holes 13 are processed on one wing plate of the second connecting piece body 15, and the second connecting piece body 15 is welded with the side wall of the template 11.
Two first connecting pieces 7 and two second connecting pieces 9 on the same template 11 are welded in sequence to form a frame, namely two ends of one first connecting piece 7 are respectively welded with the two second connecting pieces 9.
The first through holes 12 of two adjacent second connecting pieces 9 fixedly connected to two adjacent templates 11 are correspondingly arranged, and the corresponding first through holes 12 of the two second connecting pieces 9 are connected through bolts 10.
At least two supporting ribs 8 are fixedly connected to the inner arc surface of each template 11.
Before filling, the ground of an unsafe roadway 4 is cleaned, a log is placed every 1m along the passing direction of the roadway 4, the length of the log can be the same as the width of the roadway 4 for the purpose of stabilizing the log, and all logs laid on the ground of the roadway 4 form a cushion layer 1. According to the length of the filling roadway 4, a corresponding number of prefabricated members with the length of 1m and the diameter of 2.5m are sequentially placed on the cushion layer 1, and the interiors of all the prefabricated members are communicated to form the channel 2. Arranging vertical braces between the top of the prefabricated part and the top of the roadway to enable the vertical braces 6 to tightly support the top of the roadway 4 and the top of the prefabricated part, and respectively arranging cross braces 5 on two sides of the prefabricated part to enable the cross braces 5 to tightly support the side wall of the roadway 4 and the side wall of the prefabricated part so as to fix the prefabricated part; then, wrapping the outer wall of the channel 2 by plastic cloth, and plastering and compacting the joint of the connecting template 11 and the joint of the adjacent prefabricated parts in the channel 2 by cement; and then, cement mortar is injected into the roadway 4 through the connected filling pipeline, all the space between the channel 2 and the roadway 4 is filled, and the filler is solidified to form a filling body 3.
The support ribs 8 welded inside the formwork 11 can prevent the formwork 11 from sinking due to the impact of the filled cement mortar during the filling process.
