Description
Technical field
The present invention relates to a kind of town road bridge technology field, more particularly to a kind of municipal concrete steel structure road bridge
Beam.
Background technology
At present, national rapid economic development, big small city possesses that number of vehicles is more and more per capita, the road in city
It is increasingly congestion, although urban road is in a large amount of newly-increased and rectification, but present situation is still more to carry out also congestion.
Intersection in city, for pedestrian, the safety of vehicle and the consideration maintained order, generally sets at the parting of the ways
There are traffic lights automatically control traffic order, vehicle is required for stopping when traveling encounters red light to crossroad and waited,
And the simply pedestrian for the vehicle parking waiting simply kept straight on for that need not turn.When distance farther out when, it is necessary to pass through crossing
Inherently more, if each crossing is required for waiting once, even repeatedly red light could pass through, and also will result in whole piece road
On rest on road and wait the car for mouth of passing by one's way more, and then generate congestion in road problem.As can be seen here, it is ensured that straight in road
The unobstructed vehicle that is not detained of runway is the basic method for solving traffic congestion.And make road forever unobstructed, it is necessary to be built at crossing
Vertical viaduct.And in many mature cities such as Changsha, a large amount of populations are poured in, the increase of a large amount of vehicles is driven, but city is in itself
Design and the reserved of road lead to not build viaduct on existing road, even and if there is space to build, concreting it is vertical
Hand over bridge cost high, construction period is longer, and president's time effects road traffic in construction, build row on many roads at present
People's metal bridge, but the bridge pier of metal bridge is larger, the traffic also having had influence on ground.
The content of the invention
The applicant provides a kind of municipal concrete steel structure road and bridge, and it has, and bridge pier floor space is small, when building
Between it is short, can anti-down resistance to movement the characteristics of.
In order to solve the above problems, the present invention uses following scheme：
A kind of municipal concrete steel structure road and bridge, including bridge pier, bridge pier and abutment, bridge pier are fixed on bridge pier and propped up
Support below the abutment, the bridge pier includes pile and support stake, the pile include many in packing shape be distributed grab the thin end of the scroll and
It is fixedly installed in the pressure plot that the thin end of the scroll upper end is grabbed described in many, the pressure plot and cavity structure of the support stake in one；It is described
The thin end of the scroll is grabbed for curved hollow pipe, the head for grabbing the thin end of the scroll has angle, and the diameter for grabbing the thin end of the scroll is from afterbody to head
Taper into, head of blocking up is placed with the angle for grabbing the thin end of the scroll, the head of blocking up is snapped in the neck on the outside of angle；It is described
Grab the convex surface upper lateral part of the thin end of the scroll and be provided with upper end open in vertical fixing hole, the vertical fixing hole and be plugged with fix bar,
The upper end of the fix bar for grabbing the thin end of the scroll is connected by steel wire；Groove is provided with the pressure plot, the groove floor in pressure plot is set
Have with grabbing ground club head to the hole being adapted to, the upper end in the pressure plot is provided with screwed hole, and the bridge pier is connected with bridge pier by screw
Connect, the abutment and bridge pier mode connects for screw.
It is used as the further improvement of above-mentioned technical proposal：
The end of the steel wire is twisted one in pressure plot.
The ground bar side wall of grabbing is provided with multiple reinforced holes.
The reinforced hole tilts upward setting from the Inside To Outside for grabbing the thin end of the scroll.
Pressure plot inner bottom surface is concave surface.
The present invention provides a kind of installation method of the municipal concrete steel structure road and bridge, including：
Grab the installation process of the thin end of the scroll：The hole in pressure plot can be put down by digging on the ground, will be grabbed the thin end of the scroll and utilized hydraulic test pressure
Enter underground, many are grabbed the thin end of the scroll into tree root disc distribution, are grabbed the thin end of the scroll and are pressed into after correct position, by fix bar from the upper end for grabbing the thin end of the scroll
Opening insertion, and inserted from fixing hole；Pour into cement from the upper end for grabbing the thin end of the scroll, during cement is poured into, will grab the thin end of the scroll to
Upper lifting a small distance, using the squeezing action of cement, head of blocking up is separated with angle, and cement extrudes infiltration soil from angle
In；
Press the installation process in plot：After grabbing the cement in the thin end of the scroll and filling but when not spilling over, then pressure plot is placed in grabs ground
In the upper end of bar, the base apertures for grabbing the thin end of the scroll insertion pressure plot；After the completion of pressure plot is combined with grabbing the thin end of the scroll, steel wire is connected bar
Upper end, and all steel wires are twisted one；Cement is poured into from the upper end of support stake, inner chamber and the drowning in whole pressure plot is filled up
Grab the thin end of the scroll and steel wire；The hole dug is filled and led up using cement, and covers pressure plot；
The installation process of bridge pier：By the lower end of bridge pier by screw with pressing the upper end in plot to be connected, finally by abutment and bridge
The upper end of pier is connected by screw.
The technical effects of the invention are that：
The present invention grabs ground structure using lower embedding type, the reasonable in design, ingenious；Tree root disc distribution grabs the thin end of the scroll,
Strong connection is formed with ground, it is hollow to grab in the thin end of the scroll after cementing, improve selve support intensity and raising and the combination of soil
Power；Combined using pressure plot with grabbing the thin end of the scroll, the pressure exposed part floor space outside ground in plot is small, will not take excessive road
Road, does not interfere with traffic above-ground.
