Abstract
The utility model relates to a temporary bridge for erecting an existing railway overhead in sections with soft foundation or high water level. The existing railway is erected overhead by utilizing simple buttresses and temporary beams at the two sides of the existing railway to form a temporary bridge erected for the first time, and the existing railway is erected overhead again by utilizing columniform piers, rectangular bridge abutments and temporary beams below the existing railway to form a temporary bridge erected for the second time. After the temporary bridge is erected for the first time, a plurality of vertical sheet piles are connected below the temporary beams, protective walls are connected with the outer sides of the sheet piles, a space for the operation of drilling mechanical equipment is formed between every two adjacent sheet piles, the top of the space is provided with I-beam as a top support, and the bottom of the space is provided with a bottom support formed by concrete pouring to form a working channel for constructing a pile foundation. The pile foundation is formed by drilling downwards in the working channel and pouring, and the upper part of the pile foundation is manufactured into a rectangular bridge abutment bearing platform, a platform body and a pier capping beam. By adopting the temporary bridge for erecting the railway overhead in sections with soft foundation or high water level, land levy and remove are reduced, land can be little occupied, the engineering is ensured to be smoothly actualized, and the safe operation of the existing railway can be effectively ensured at the same time.
Description
Technical field
The utility model relates to the construction technology of setting up suspension bridge on the existing railway of high water level, geological conditions difference and circuit difficulty, specifically is a kind of suspension bridge that is used for soft base, the built on stilts existing railway in high water level location.
Background technology
Construction along with railway, highway, urban road, newly-built road, railway and existing railway disturb also more and more, basically adopt usual friendship, on stride and under the mode of wearing solve, wherein usual friendship is big to railway, road safety hidden danger, basically do not consider usual friendship now, on to stride mode less to existing railway operation influence, but the mode of wearing down is very big to existing railway operation influence.
Under in the city, wear existing railway, because constructing just, line takes up an area of many, the place is limited, be difficult to carry out mostly, the general employing maked somebody a mere figurehead the construction of existing railway method, problems such as but suspension bridge pier difficulty of construction is very big under high water level, geological conditions extreme difference situation, and job practices existed potential safety hazard big in the past, and the construction period is long.At under wear existing railway, construction railroad suspension bridge how under the condition of guaranteeing railway operation, high water level, geological conditions extreme difference, the construction of suspension bridge pier and safeguard procedures are engineering key of success.
Summary of the invention
The purpose of this utility model provides a kind of suspension bridge that is used for soft base, the built on stilts existing railway in high water level location, can effectively solve the problem that above-mentioned prior art exists.
This suspension bridge that is used for soft base, the built on stilts existing railway in high water level location of the present utility model, comprise just beam, columnar pier, rectangle abutment and pile foundation, it is characterized in that: utilize to be positioned at the simple and easy buttress of existing railway both sides and the just empty existing railway of roof beam structure, form the suspension bridge that sets up the first time; Utilization is positioned at columnar pier under the existing railway, rectangle abutment and the just empty existing railway of roof beam structure, forms the suspension bridge that sets up for the second time; After for the first time setting up suspension bridge, just the beam below is connected with several vertical sheet piles, the sheet pile outside is connected with retaining wall, between two adjacent sheet piles, form the space that to satisfy the operation of drilling machine equipment, the top in this space has i iron to do to shore, and the service aisle of the bottom bracing of concreting for the construction stake basis arranged at the bottom; Hole downwards in service aisle and build the formation pile foundation, rectangle abutment cushion cap, abutment body and bridge pier bent cap are made in this pile foundation top.
Aforesaid i iron is shored and is adopted angle steel laterally to connect.
Be equipped with i iron in the aforesaid concrete bottom bracing.
Wide * the height of aforesaid service aisle is 5m * 6m.
The utlity model has following advantage:
(a) adopt the suspension bridge overhead wire in locations such as high water level, soft bases, both reduced expropriation of land and removed, take ground less, can make the engineering smooth implementation again, can ensure the safe operation of existing railway simultaneously again effectively.
(b) utilize and set up just beam twice, the temporary bridge for construction pier can carry out accelerating construction progress synchronously one by one.
(c) save engineering cost, economical rationality, technological innovation.
More have superiority on the existing railway of many railway operations such as the utility model job practices is applicable under the newly-built road wears existing railway, interior at the train station.
Description of drawings
The suspension bridge structural representation of Fig. 1～5 for illustrating and form according to the suspension bridge construction process that the utility model proposes.
The specific embodiment
Construction graphical analysis procedure below in conjunction with the suspension bridge pier is described in further detail the utility model:
Among Fig. 1, do simple and easy buttress 3 earlier, utilize just beam 1 built on stilts existing railway 2 in the existing railway both sides.
Among Fig. 2, merogenesis construction retaining wall 8 utilizes retaining wall 8 supportings, the job-hopping hand excavation soil body 5, construction sheet pile 7.Add i iron 6 at 7 tops of two sheet piles and do to shore, adopt angle steel laterally to connect between i iron.The excavation soil body 5 is to sheet pile bottom design absolute altitude and build sheet pile.
Among Fig. 3, excavate the soil body 5 between two sheet piles, the supporting while excavating is excavated to and can satisfies till the space that drilling machine equipment operates, and builds steel concrete in this bottom, space and makes bottom bracing 9, to form the service aisle of suspension bridge pier pile foundation 10 constructions.Can in concrete, add i iron during construction bottom bracing 9.
Among Fig. 4, set up drilling machine equipment, temporary bridge for construction pier pile foundation 10 is holed to design elevation, and the segmentation descending reinforcing cage is built pile foundation.Construct then abutment cushion cap, abutment body and the bridge pier bent cap 11 on top.
Among Fig. 5, vertically move and set up just beam 1, the excavation railway is the beam cubic metre of earth 5 road grooves to newly-built road 4 down just, and remove influential part retaining wall 8.Newly-built road 4 road surfaces and ancillary facility thereof on the groove of construction road.
