Description

Overhead type comprehensive pipe gallery bridge

Technical Field

The utility model relates to a technical field of utility tunnel design specifically is an overhead type utility tunnel bridge, and it is for combining bridge design theory in the utility tunnel design to the realization can satisfy utility tunnel service function, can solve the local highway section of piping lane again and need make somebody a mere figurehead to stride across the condition such as river course or cross road.

Background

The comprehensive pipe gallery engineering is that a municipal shared tunnel is built under urban roads, various municipal pipelines such as electric power, communication, water supply, reclaimed water, cold and hot water pipes, fuel gas and the like are integrated, and unified planning, unified construction and unified management are carried out, so that comprehensive utilization of underground space and resource sharing are achieved, and the intensive management target of the pipelines is achieved.

The utility tunnel is generally built below urban roads and has a certain burial depth. For a long-distance comprehensive pipe gallery, a plurality of obstacles inevitably meet along the line, and the obstacles are avoided by adopting a mode of inverted rainbow under the ground. And for the areas with large relief, large change of longitudinal height difference, crossing deep valleys, river channels, crossing roads and the like, the inverted siphon construction depth of the pipe gallery is deep, the construction difficulty is large, and the manufacturing cost is high.

Introduce the built on stilts design of strideing across of utility tunnel with the bridge design theory, both can satisfy utility tunnel pipeline and concentrate the function of operation pipe gallery, can reach the built on stilts requirement of strideing across the obstacle in order to connect full-line pipe gallery simultaneously of utility tunnel again. An overhead comprehensive pipe gallery bridge is a reasonable solution for a pipe gallery to cross an obstacle in an overhead manner.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an overhead type utility tunnel bridge is a design of the overhead obstacle of pipe corridor, through the mode that utility tunnel design and bridge design theory combined together, handles special area or special highway section pipe gallery and imbeds in the below ground unreasonable, and the special circumstances that needs built on stilts to pass through.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides an overhead type utility tunnel bridge, includes the utility tunnel body, its characterized in that the cushion cap is established to utility tunnel body bottom, sets up pipe gallery bridge abutment on the cushion cap at overhead type utility tunnel bridge both ends, and the tip and the pipe gallery bridge abutment of utility tunnel body link to each other, and pipe gallery bridge abutment front wall is seted up with pipe gallery body matched with hole to the utility tunnel body passes through pipe gallery bridge abutment links up with the outer piping lane.

Further, set up the pier on the cushion cap at overhead type utility tunnel bridge middle part, on the pier was arranged in through the support in the middle part of utility tunnel body, utility tunnel body both ends were then arranged in on the pipe gallery bridge abutment through the support, increased pipe gallery section bottom plate and wallboard thickness in the support department of pipe gallery bridge abutment and pier to satisfy the requirement that the support department sheared.

Further, the joint department of piping lane bridge abutment and utility tunnel body sets up the expansion joint.

Further, the top elevation of utility tunnel body of overhead utility tunnel bridge flushes with ground, and outer piping lane includes underground piping lane and the connecting pipe gallery that links to each other with underground piping lane, connecting pipe gallery one end is connected with underground piping lane, and the other end then inclines to extend upwards to be connected with overhead utility tunnel bridge.

Further, the overhead type comprehensive pipe gallery bridge is arranged above an underpass road, a river or an underpass green land.

The utility tunnel that adopts this scheme design need not to adopt big buried depth, long distance to fall the rainbow and link up the full-line piping lane, but utilizes the box cross-section of box cross-section girder bridge and the characteristics that utility tunnel standard section form is unanimous basically, when dodging the barrier along with connecing both sides underground utility tunnel, realizes utility tunnel's bridge beam type and stridees across. The utility model discloses novel structure, safe and reliable has higher economic benefits.

Detailed Description

The invention is further described with reference to the following figures and examples.

An overhead comprehensive pipe gallery bridge is used for treating the special condition that a pipe gallery in a special area or a special road section is unreasonably buried under the ground (for example, in an area with an underpass road, a river or an underpass green land) and needs to be passed through in an overhead mode by combining the design of the comprehensive pipe gallery and the design concept of the bridge.

By adopting the calculation principle of the prestressed box-section beam bridge structure and combining the stress characteristics of the box-section beam bridge, the clear height and the clear width of the standard section are properly adjusted on the premise of meeting the premise that the pipeline of the comprehensive pipe gallery enters the gallery, so that the most reasonable design section is determined.

Pipe gallery bridge satisfies pipe gallery personnel and patrols and examines needs, and 3 front walls of pipe gallery bridge abutment do according to pipe gallery standard section and open the hole and handle, and the abutment structure combines the pipe gallery to link up the demand setting.

Because 7 positions at pipe gallery bridge pier support can not set up the cross slab and satisfy the requirement that support department shears, consequently the utility model discloses in, 7 departments of pipe gallery bridge pier increase pipe gallery section bottom plate and wallboard thickness to satisfy support department requirement of shearing.

The pipe gallery bridge ventilation system designs with full-line utility tunnel is unified, and each cabin independently ventilates, satisfies utility tunnel ventilation design's standard requirement, can not set up the ventilation hole on the box section roof beam wallboard.

Overhead type utility tunnel bridge generally adopts the pile foundation form, and pipe gallery bridge abutment should set up the expansion joint with pipe gallery standard section linking department to should consider the influence that the settlement difference of linking department two parts structure brought, according to the geology soil layer condition, take foundation soil to trade measures such as filling or pile foundation transition, reduce bridge abutment department and subside the difference excessively greatly.

According to the kind of the concrete corridor pipeline of going into in utility tunnel inside, make clear and definite the usage and the scope of piping lane bridge. If the comprehensive pipe gallery contains high-voltage power cables and gas pipelines, the comprehensive pipe gallery cannot be made into a pipe gallery bridge form.

The design of the overhead comprehensive pipe gallery bridge meets the relevant design requirements of the design specification of the comprehensive pipe gallery and the design specification of the bridge at the same time.

The utility model discloses an overhead type utility tunnel bridge realizes that the piping lane stridees across the barrier function, novel structure, and safe and reliable has higher economic benefits. The utility model discloses need not to adopt big buried depth, long distance to fall the rainbow and link up full line piping lane, but utilize the box cross-section of box cross-section beam bridge and the characteristics that utility tunnel standard section form is unanimous basically, in the same direction as connecing both sides underground utility tunnel when dodging the barrier, realize utility tunnel's bridge beam type and stride across.
