Abstract
The invention relates to a prefabricated block of a collapse preventing structure in a construction process of a subway, a mine tunnel and a highway tunnel and a construction method thereof. The construction method comprises steps of prefabricating a bottom surface block, a right angle block, a vertical block and an arc top block according to set dimensions. During construction, prefabricated blocks are used for splicing and calking cyclically, thereby ensuring safety and reliability, reducing cost and greatly quickening construction period. The prefabricated block can be used in the construction process of the subway, the mine tunnel, underground pipeline network, the highway tunnel or underground factory, and the like.
Description
Technical field
The present invention relates to a kind of architectural engineering technology, the anti-collapse method structure prefabricated component and the building method thereof of work progresss such as tunnel, particularly a kind of mine, city underground, highway tunnel, underground shelter.
Background technology
At present, facilities such as tunnel, various mine, city underground, highway tunnel, underground shelter in work progress, the landslide accident very easily occurs, gently then cause any property loss, and engineering is scrapped and changed its course, the heavy serious accident that then causes tens people even hundreds of people.This also is that anyone any unit all is reluctant to see, also is that national governments do one's utmost to avoid.
Summary of the invention
At the deficiencies in the prior art, the invention provides and a kind ofly both can reduce the building operations cost in subway, tunnel, mine, highway tunnel construction process, can guarantee construction safety again, the anti-collapse structure prefabricated section and the job practices of speeding up the work.
Prefabricated component comprises reinforcing bar and concrete structure, and some occasion also can only be used concrete structure.Reinforcing bar is horizontal and vertical layout in prefabricated component.
Baseplane and vertical plane right angle turning prefabricated component.A prefabricated groove in the middle of standing above the body of wall, the ash wall body plate that has tongue below last layer combines, and is shaped on convex tendon on the bottom panel facade in advance, has another piece to have the groove prefabricated panel and combines.With the two ends of concavo-convex corresponding vertical direction, an end is a groove, and an end is a convex tendon.
The cambered surface prefabricated component.According to the designed channel width is inner diameter size, the thickness that configures of bearing capacity on request, and upper and lower surface is prefabricated groove and convex tendon respectively, and perpendicular direction two ends respectively are prefabricated into groove and convex tendon.
Prefabricated component in the middle of the arc end face, two sides are prefabricated into groove, and two ends are prefabricated into groove and convex tendon respectively.
Vertical plane combines the transition prefabricated component with cambered surface.Be prefabricated into below and face convex tendon directly, in the middle of setting the cambered surface size, be prefabricated into the cambered surface groove above.
Prefabricated component in the middle of the baseplane.Two sides are prefabricated into groove, and two ends respectively are prefabricated into groove and convex tendon.
Above-mentioned prefabricated component all can be designed to different sizes as required.
Above-mentioned prefabricated component, in the construction assembling process, groove and convex tendon are tenon structures, each prefabricated component is the bonding crack position by 0.5 or 0.8 of preform length.During construction, place prefabricated component in the following order.1. put prefabricated component in the middle of the baseplane, 2. put button bottom surface, both sides prefabricated component, 3. put button baseplane and vertical plane right angle turning prefabricated component, 4. put button two vertical plane face prefabricated components, 5. put the button vertical plane and combine the transition prefabricated component with cambered surface, 6. put button cambered surface prefabricated component, 7. put the middle prefabricated component of button arc end face, one square arch cross section assembling is finished, and overtime inserts for bonding crack successively by 0.5 or 0.8 of preform length, and the grey pump in peripheral all around space pumps into concrete strengthening.Whenever push away certain distance and just can assemble one section, advance successively, complete until engineering.
Like this, safe and reliable without any the danger of landslide in work progress, to install while advancing, the duration process is accelerated.But because the work of a large amount of cast-in-sites. transfer to on-the-spot outer making that batch production is made, the production efficiency height, quality controllable secure.And can save the huge amounts of material and the work time cost of interim support usefulness.Hangzhou Subway landslide incident was a lesson written in blood in 2008, with method on this, similar accident will not occur.

The specific embodiment
Embodiment one
As shown in Figure 1, be used for city underground excavation construction process, dig a vertical openings earlier, laterally excavate then on whole good plane, digs into 3 or 5 meters, level up the plane, lay ground middleware A1 repaves and puts prefabricated component A2, A3, put button prefabricated component A4 again, put button prefabricated component B4 again, because fluted tenon structure, prefabricated component has certain stable support effect, and then put button prefabricated component B3, and put button prefabricated component B1 at last again, be built into required cross sectional shape with prefabricated component like this.Such circle body structure is formed, and each layer prefabricated component is bonding crack by 0.5 or 0.8 of its preform length, and the beginning part can be by the short part of 0.5 or 0.8 a prefabricated part of its preform length.For making circle body structure and peripheral bond good, remove the gap, pump into mortar with pump, form a firm barrel, installing space of later every propelling builds one section, repeatedly circulation, when advance certain apart from the time, but floor file iron rail, for transporting native stone usefulness, circulation construction like this, finish up to next exit to get through just after 80%～90% the workload and finish, safe and efficient.
Claims (3)
1, prefabricated component comprises reinforcing bar and concrete structure.It is characterized in that being prefabricated into die and convex tendon respectively at upper and lower surface.On vertical concave and convex direction, also be prefabricated into die and convex tendon, implement the seal tenon structure.In the prefabricated section in order to strengthen intensity, in length and breadth to arranging reinforcing bar.
2, the anti-collapse structure of prefabricated section is characterized in that comprising prefabricated section, bottom surface block, right angle block, vertical blocks, arc top board piece.Each column connects employing seal tenon structure, pegs graft mutually between the plate, and the plate seam is diverged to mutually, and peripheral difference is stitched and tamped with concrete.Can peg graft while excavating.
3, prefabricated section as claimed in claim 1, because the circle body of forming mainly is to bear pressure, some occasion also can be without reinforcing bar.
