Abstract
The utility model relates to an underground passage construction treatment structure for an urban road. The utility model aims to provide an underground passage construction treatment structure for an urban road, which is simple in structure, convenient to implement and low in cost so as to lower construction risk and reducing influence on traffic. The technical scheme of the utility model is as follows: by using the underground passage construction treatment structure for an urban road, a plan is made to excavate an underground passage under existing road surfaces of an urban road. The underground passage construction treatment structure for an urban road is characterized in that a temporary overpass steel structure bridge for vehicle traffic is erected above the underground passage, and the steel structure bridge communicates the existing road surfaces. The utility model is applicable to underground passage construction engineering of an urban road.
Description
Technical field
The utility model relates to a kind of urban road underground passage construction processing structure.Be applicable to urban road underground passage construction works.
Background technology
Urban transport problems has been industrially developed country and the area problem of puzzlement for it always since this century.Entered since the eighties, the economic trade in China city and social activities are day by day busy, and unprecedented increasing rapidly occured urban traffic, and traditional road equipment can not adapt to the needs of modern society.The current industrial development is very fast, and the traffic problems in city are extremely serious, must plan in advance and early improvement.
Want the transport solution problem of blocking up, keep the unimpeded of vehicle, just must carry out the relatively way of shunting of people's car, except having traffic lights and traffic-police guarantee, underground passage is built in effective measure exactly, and pedestrian and Vehicle Driving Cycle are spaced from each other.
The method of building underground passage at present both at home and abroad has cut and cover method and hidden construction process.The cut and cover tunneling risk is lower, but larger to existing traffic impact, and the hidden construction process construction risk is higher, but less to existing traffic impact.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of simple in structure, implement convenient and the low urban road underground passage construction processing structure of cost, to reduce construction risk, reduce the impact on traffic.
The technical scheme that the utility model adopts is: a kind of urban road underground passage construction processing structure, under the existing road surface of urban road, intend underground passage of excavation, it is characterized in that: set up above underground passage and can stride steel structure bridge for the interim of vehicle pass-through, existing road surface is led in this steel structure bridging.
Described underground passage adopts cut and cover tunneling.
The beneficial effects of the utility model are: 1, stride steel structure bridge temporarily by setting up on existing road surface, realize that motor vehicle separates with the solid of underground passage construction, the farthest traffic of the existing road of reduction solves the underground passage construction to the impact of existing traffic; 2, because steel structure bridge is striden on having set up temporarily in the underground passage top, can select the lower cut and cover method of construction risk to construct when underground passage excavates, reducing construction cost shortens construction period, improves efficiency of construction.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Present embodiment advantage in conjunction with hidden construction process on the basis of original cut and cover method makes improvements.As shown in Figure 1, intend in this example at underground passage 4 of the 1 time excavation in the existing road surface of urban road, for reducing construction risk, underground passage 4 adopts cut and cover method to excavate, yet cut and cover method is larger on the impact of road traffic, will cause the consequence that makes the matter worse to the road traffic that originally just blocks up very much.For solving cut and cover method to the impact of road traffic, set up above underground passage 4 and stride steel structure bridge 3, existing road surface 1 is led in this steel structure bridging, can be current for motor vehicles on it temporarily, realize that the solid of vehicle pass-through and underground passage construction separates, farthest reduce the traffic of existing road.Striding 3 constructions of steel structure bridge on wherein interim need satisfy the headroom of normal vehicle and control.
The concrete construction method of present embodiment is as follows:
1), in the subsurface geology condition preferably in the situation, underground passage 4 can adopt puts the slope excavation.Perform in the appointed place first and temporarily stride steel structure bridge 3, then existing road traffic is guided into and stride steel structure bridge 3 on interim, need limit simultaneously passing through of heavy vehicle, realize at last the excavation construction to underground passage 4 foundation ditches;
2), can not satisfy at geological conditions and put in the sloping excavation situation, can perform first the space enclosing structure 2 of underground passage 4, stride steel structure bridge 3 on performing again temporarily, then stride steel structure bridge 3 on existing road traffic being guided into temporarily, need limit simultaneously the current of heavy vehicle, realize at last the excavation construction to the underground passage foundation ditch.The design of space enclosing structure 2 needs base area lower channel 4 residing geological conditionss, uses relevant design software and calculates the form that foundation pit enclosure structure adopts.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
Claims (2)
1. urban road underground passage construction processing structure, the lower excavation underground passage (4) of intending on the existing road surface (1) of urban road, it is characterized in that: set up in the top of underground passage (4) and can stride steel structure bridge (3) for the interim of vehicle pass-through, existing road surface (1) is led in this steel structure bridging.
2. urban road underground passage construction processing structure according to claim 1 is characterized in that: described underground passage (4) employing cut and cover tunneling.
