Fig. 1 is a schematic structural view of the present invention.
In the figure: 1-reinforcing thick walls; 2-post-casting the strip; 3-shearing resistance; 4-deformation joint.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
according to the soft soil foundation utility tunnel that reduces movement joint setting that figure 1 shows, include:
the pipe rack body is provided with a pipe rack body,
the deformation joint 4 is arranged between every two sections of the pipe gallery body;
the reinforcing thick wall 1 is connected to the outer side of the deformation joint 4, and covers the deformation joint 4;
the post-cast strip 2 is connected to two ends of the reinforced thick wall 1;
the shear resistant ribs 3 are connected in the reinforcing thick wall 1 and are perpendicular to the deformation joints 4.
During in-service use, in order to reduce the problem that soft soil foundation utility tunnel structure produced subside, warp easily, during the construction, reduce the movement joint setting, cancel former movement joint department stagnant water, waterproof structure, the reinforcing bar leads to long the setting, nevertheless strengthens setting up movement joint department structure. Through connect in 4 outsides of movement joint and cover movement joint 4 strengthen thick wall 1, connect at the post-cast strip 2 of strengthening thick wall 1 both ends and set up strengthen in thick wall 1 and with movement joint 4 vertically shear bar 3, shear bar 3's setting, the effectual shear force of having resisted the movement joint both sides production that arouses because of the soft soil deformation, effective less piping lane main part subsides and warp, has improved soft soil foundation utility tunnel's structure wholeness ability. Strengthen the setting of thick wall 1, can effectual reduction piping lane tip stress concentration's influence. The steel bar is simple in structure, convenient and quick to construct, and effectively reduces water leakage risks.
Example two:
according to the soft soil foundation utility tunnel that reduces movement joint setting that figure 1 shows, with the embodiment one difference lies in: the reinforcing thick wall 1 is symmetrically arranged by taking the deformation joint 4 as a center.
When the in-service use, this technical scheme's adoption for soft soil foundation utility tunnel's stability is better, and the effectual wholeness ability that has strengthened soft soil foundation utility tunnel structure.
Example three:
according to the soft soil foundation utility tunnel that reduces movement joint setting that figure 1 shows, with the embodiment one difference lies in: the section of the reinforcing thick wall 1 is trapezoidal.
When in actual use, strengthen thick wall 1 and adopt the cross-section to be trapezoidal technical scheme, not only effectively improved the wholeness ability of soft soil foundation utility tunnel structure, make the connection of strengthening thick wall 1 and post-cast strip 2 more harmonious moreover.
Example four:
according to the soft soil foundation utility tunnel that reduces movement joint setting that figure 1 shows, with the embodiment one difference lies in: the post-cast strips 2 are symmetrically connected to two ends of the reinforced thick wall 1.
