Specific embodiment
By the technology contents of invention are described in detail, construction feature, are reached purpose and efficacy, simultaneously below in conjunction with embodiment
Cooperation attached drawing is described in detail.
The assembled underground pipe gallery of this case includes the piping lane ontology 1, piping lane gallery 2 and shock reducing structure 3 of pre-buried underground.Below
Each part and its working principle will be illustrated in conjunction with 1~attached drawing of attached drawing 3.Wherein, left up and down described in the present embodiment
Right positional relationship is corresponding with the positional relationship of assembled underground pipe gallery shown in attached drawing 1, laterally refers to shown in attached drawing 1
The direction that headers/footers or so extend longitudinally refers to the direction that diaphram wall shown in attached drawing 1 extends up and down.
With reference to the accompanying drawings shown in 1, piping lane ontology 1 includes top plate 11, positioned at the bottom plate 12 of 11 lower section of top plate and positioned at top plate
11 and the left and right sides of bottom plate 12 diaphram wall 13, top plate 11, bottom plate 12 and two diaphram walls 13 surround one jointly
A damping cavity 14.Wherein, top plate 11, bottom plate 12, diaphram wall 13 are reinforced concrete structure.
There are four the tools of piping lane gallery 2, and four piping lane gallerys 2 are arranged in damping cavity 14, four piping lane gallerys 2 it is outer
Multiple shock reducing structures 3 are provided between peripheral wall surfaces and the inner peripheral wall of damping cavity 14.And the periphery of two neighboring piping lane gallery 2
Multiple shock reducing structures 3 are also equipped between wall surface, so that each piping lane gallery 2 is wrapped by multiple shock reducing structures 3 in damping cavity 14
It surrounds.Each piping lane gallery 2 is also reinforced concrete structure, and the cross section of each piping lane gallery 2 is rectangle, each shock reducing structure 3
Cross section be circle.The assembled underground pipe gallery of this case includes being connected to the feeder connection of each piping lane gallery 2 (not show in figure
Out), maintenance personal can be entered wherein by the feeder connection, carry out upkeep operation.In other embodiments, of piping lane gallery
Number is not limited to described above four, be also possible to one to three or more, and the vertical sectional shape of piping lane gallery is not yet
It is limited to rectangle described above, is also possible to circle or other shapes.
When meeting with the impact of earthquake, the shock reducing structure 3 of 2 periphery of piping lane gallery is that piping lane gallery 2 provides damping and buffering
It acts on and deformation can be restored after impact force, this just needs shock reducing structure 3 not only to have damping property, also to have certain
Intensity.
With reference to the accompanying drawings shown in 2, shock reducing structure 3 is the internal steel pipe 31 for being filled with damping material 32, and damping material can reduce ground
Influence of the destructive power to shock reducing structure is shaken, damping material herein selects foamed resin.Certainly, in other embodiments, shock reducing structure
Elastic deformation can be generated and have the structure composition of certain rigidity, such as the rubber-coated material of reinforcing bar by being also possible to other, such as
Shock reducing structure is made using only rubber material in fruit, since rubber material is easy to produce crackle when bearing biggish impact force,
Rigidity does not reach requirement.Therefore, for shock reducing structure when keeping out for piping lane gallery or damping is from the impact force of seismic wave, itself is not
Irreversible damage easily occurs, can reuse, damping effect is more preferable.
With reference to the accompanying drawings shown in 3, each piping lane gallery 2 includes that multistage divides gallery 21, is connected between adjacent two sections of points of gallerys 21
Flexible connector 22.Flexible joint 22 herein is made of rubber material, when meeting with the impact of seismic wave, flexible joint 22
Play the role of buffering between adjacent two sections of points of gallerys 21, compared to integrally-built piping lane gallery, this utilization of this case
The structure that flexible joint connects two points of gallerys can avoid the case where piping lane gallery is broken off.In order to ensure piping lane gallery 2 is in its length
Stress is more uniform on degree direction, and the length of shock reducing structure 3 and the length of piping lane gallery 2 are roughly equal.
The working principle of the assembled underground pipe gallery of this case is as follows: when earthquake occurs, the longitudinal wave and cross that are generated at focus
Wave causes impact force to the vertical and horizontal of the assembled underground pipe gallery of this case respectively during successively reaching earthquake centre.Specifically,
When longitudinal wave comes temporarily, the shock reducing structure 3 of 12 lower surface of 11 upper surface of top plate and bottom plate absorbs the impact force from longitudinal wave, plays damping
With the effect of buffering；When shear wave comes temporarily, between two neighboring piping lane gallery 2, between piping lane gallery 2 and two diaphram walls 13
Mutual shearing slip can occur by shock reducing structure 3, consume the impact force of shear wave, guarantee the safety and stabilization of each piping lane gallery 2.
The construction method of the assembled underground pipe gallery of this case, construction procedure are as follows:
1. digging out two parallel continuous foundation trenches on the ground in advance, diaphram wall is then buried in each continuous foundation trench
13；
2. the foundation pit of set depth value is dug out on the ground between two diaphram walls 13；
3. the interior bottom of foundation pit is arranged in bottom plate 12 and is pushed against between two diaphram walls 13；
4. the multiple shock reducing structures 3 of accommodated side-by-side on the upper surface of bottom plate 12；
5. piping lane gallery 2 is supported on shock reducing structure 3；
6. refilling multiple shock reducing structures 3 between the periphery wall surface of piping lane gallery 2 and the interior sidewall surface of diaphram wall 13, make
Obtain the periphery wall surface that shock reducing structure 3 is covered with piping lane gallery 2；
7. top plate 11 is covered on the oral area of foundation pit and is pushed against between two diaphram walls 13, and make top plate 11
Lower surface is adjacent to 3 phase of shock reducing structure on 2 upper surface of piping lane gallery；
8. banketing on top plate 11 and covering top plate 11, the assembled underground pipe gallery of this case is finally installed.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
