Description

Rain pipe buries structure

Technical field

Hydraulic engineering harbour safeguarding structure field is the utility model is related to, more particularly to a kind of rain pipe buries structure.

Background technology

Rain pipe is embedded in shore protection, is easy to a kind of water conservancy structure for importing rain water or other fluid in the waters such as river.

At present, common rain pipe constructing structure is typically provided with cofferdam in shore protection towards the side in the waters such as river, encloses Weir is arranged to separate with shore protection mostly, and cofferdam is built up using the single sandy gravel of structure or soil, and worker is in cofferdam Constructed in the space crossed, but in the waters outside cofferdam, there is rushing for ship wave when impulsive force, the vessel motion of current Brush, is easily impacted to cofferdam, makes it impaired.

Utility model content

The purpose of this utility model is to provide a kind of rain pipe and buries structure, and it has stabilized structure, in work progress, The facilities such as underwater foundation are protected, the advantages of reducing constructing structure impaired possibility.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of rain pipe buries structure, including shore protection, and rain pipe is set in the shore protection, it is characterised in that：The shore protection Precast square pile is provided with close to waters side, two corrals for isolating wall and precast square pile with waters are provided with around the wall Weir, connected between the wall and cofferdam by concrete foundation, the rain pipe is provided with the second box cut, institute away from the side on ground The second box cut is stated from wall to away from waters side to extend.

It is arranged such, after setting cofferdam, cofferdam isolates from the current in waters outside, and slot milling is constructed for worker. Precast square pile had both enough improved the self-strength of wall, was connected between cofferdam and wall by concrete foundation, and concrete foundation is by cofferdam and wall After body links into an integrated entity, cofferdam, concrete foundation, wall form an entirety, after the impact by water flow impact pressure and ship wave, Compared to the cofferdam set independently of each other, the constructing structure with concrete foundation is more firm, not easily damaged.Earth excavation groove is set Afterwards, the space that can have abundance is used for embedded rain pipe of constructing.And in work progress, it can reduce to rain pipe and its week The pressure of the submerged structure on side, reduce the possibility that rain pipe and underwater foundation are surprisingly damaged.

Further set：The concrete foundation from wall to tilting extension at cofferdam, the concrete foundation close to wall one Side vertical height is higher than its vertical height at cofferdam.

It is arranged such, inclined plane can bear bigger impact compared to vertical plane or horizontal plane when by impulsive force Power；And after construction terminates, the structure comes into operation, the current that inclined plane can be easy to discharge in rain pipe flow into river course.

Further set：Connected between the concrete foundation and ground by earthwork group, the earthwork group includes recessed in ground The first box cut, protrude the first backfill earthwork on ground, first box cut and the first the backfill earthwork and ground form rank Scalariform.

It is arranged such, the step structure that the first box cut and the first backfill earthwork are formed can increase cubic metre of earth group and concrete Connection area between basis, after increasing connection area, bonding strength between the two improves, and makes total more firm.

Further set：The rain pipe includes being embedded in the first pipeline at shore protection, deviates from waters side positioned at shore protection Second pipe, docked between first pipeline and second pipe.

It is arranged such, after rain pipe is divided into some segment pipes, is shortened per the length of segment pipe, is readily transported and work progress In operation.

Further set：Marked time away from ground side provided with concrete one end that the rain pipe stretches out wall.

It is arranged such, concrete, which is marked time, to be covered on rain pipe, and certain protective effect can be played to rain pipe.Work as rain pipe When the earthwork of top has pedestrian or vehicle contact, applies pressure to ground, the pressure suffered by rain pipe is marked time uniformly by concrete It is scattered, reduce the possibility of rain pipe local pressure cracking.

Further set：The concrete is provided with reinforced mesh in marking time.

It is arranged such, reinforced mesh plays a part of reinforcement, it is possible to increase the intensity that concrete is marked time, the stress even if concrete is marked time Crack is produced, can be also connected by reinforced mesh, not easy to break is two separate individuals.

In summary, the utility model has the advantages that：Concrete foundation, precast square pile can set isostructural Under the premise of, make whole constructing structure stable；The setting in two layers of cofferdam can reduce infringement caused by water impact, with these structures To ensure the reliable and stable of constructing structure underwater foundation.
