Description

Highway rapid trough prefabricated construction

Technical Field

The utility model relates to the technical field of highway drainage, and particularly provides a highway rapid trough prefabricated structure.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

With the development of urbanization and the increasing travel demand of people, roads are widely constructed. In a road fill section, a side ditch is usually arranged outside a slope toe of an embankment side slope and used for discharging accumulated water in the boundary range of the road, wherein the accumulated water in the road range usually flows into the side ditch through the embankment side slope. In the prior art, in order to prevent the slope from being damaged by scouring, rapid troughs are usually built on the slope at intervals, and the water in the road area is collected and discharged in a centralized manner. In the road engineering provided with the central dividing strip, in order to discharge the accumulated water of the central dividing strip, an infiltration ditch is usually arranged at the bottom of the central dividing strip, and a transverse drainage pipe is arranged at intervals for discharging the water collected by the infiltration ditch. The prefabricated assembled rapid trough has the characteristics of attractive appearance, convenience in construction and the like, and is more and more applied to highway engineering in recent years.

However, the inventor finds that in the highway engineering adopting the prefabricated assembled torrent tank, if the outlet of the transverse drain pipe is arranged at the torrent tank, accumulated water in the central separation zone cannot be drained due to the shielding of the precast block; if the transverse drain pipe is arranged on a common soil slope, the slope is scoured and damaged.

SUMMERY OF THE UTILITY MODEL

The problem of the ponding of zonation in can't discharging through prefabricated section rapid trough in the highway engineering that adopts the prefabricated section rapid trough is solved.

In one or more embodiments of the present disclosure, a highway rapid trough precast block is provided, which sets up a rapid trough on the side slopes of both sides of the road surface, and sets up an infiltration ditch at the bottom of the central separation strip, accumulated water in the infiltration ditch flows into the horizontal drainage pipe, the horizontal drainage pipe outlet is located on the rapid trough, the rapid trough is composed of an opening precast block and a common precast block, the common precast block is a groove structure with two convex sides and a concave middle part, the opening precast block is a middle open-ended precast block, and the opening of the opening precast block corresponds to the horizontal drainage pipe outlet.

One of the above technical solutions has the following advantages or beneficial effects:

1) in the prior art, the accumulated water in the central separation zone is generally discharged through the transverse drainage pipe, but in the highway using the precast block torrent tank, the accumulated water is usually directly discharged onto the side slope, so that the side slope is scoured and damaged. The reasonable discharge of accumulated water in the central road separation zone is realized by matching the seepage ditch with the transverse drainage pipe and the rapid trough precast block.

2) In the prior art, a cast-in-place groove body is reserved at the position, where the precast block covers the outlet of the drain pipe, to prevent the side slope from being washed away, but the side slope is not attractive and the construction process is complex. And this disclosure uses the prefabricated section, and the construction is simple when comparatively pleasing to the eye.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

The problem that accumulated water in a central separation zone cannot be discharged through the precast block torrent tank in highway engineering adopting the precast block torrent tank is solved.

Furthermore, the road surface is in a cross section form with a high middle part and low two sides. This cross section form is the common cross section form on highway road surface, and this structure itself is favorable to the drainage on road surface, and surface gathered water flows to the relatively low road surface both sides of elevation easily promptly, and then flows to the rapid trough, realizes the drainage.

Further, the prefabricated section rapid trough sets up on road surface both sides side slope.

Further, the rapid trough is composed of prefabricated blocks. The rapid trough prefabricated section is for cast in situ labour saving and time saving, only need pour required prefabricated section in advance in the mould, with prefabricated section transportation to job site, the installation can.

Still further, the rapid trough groove body comprises opening prefabricated section and ordinary prefabricated section, and ordinary prefabricated section is the recess form, and there is the opening for ordinary prefabricated section groove body bottom in the opening prefabricated section, opening prefabricated section opening corresponds with horizontal drain pipe export.

Furthermore, the common precast block and the opening precast block can be manufactured by a die casting method in the prior art.

Furthermore, the opening precast block is positioned in the middle of the rapid trough. Corresponding to the transverse drainage pipe, does not affect the water collection at the upper part of the rapid trough and the drainage at the lower part.

Furthermore, the opening of the precast block is slightly larger than the transverse drain pipe, so that the installation is convenient, the precast block opening and the transverse drain pipe are plugged by adopting plugging materials such as cement mortar and the like, and the precast block opening and the transverse drain pipe are relatively sealed, so that accumulated water in the transverse drain pipe is conveniently discharged outside, and the accumulated water is prevented from permeating into the side slope.

Further, the road surface edge sets up the curb, the curb sets up loudspeaker form opening with rapid trough junction and is convenient for concentrate the collection road surface catchment.

Further, the infiltration ditch is a longitudinal infiltration ditch. Used for collecting middle zone accumulated water.

Furthermore, the infiltration ditch is communicated with the transverse drainage pipe to form a whole set of drainage system.

Furthermore, the transverse drainage pipe connecting the longitudinal seepage ditch of the central separation belt and the torrent tank has a certain transverse gradient. The accumulated water can flow from high to low position.

In the highway engineering adopting the precast block torrent tank, the length of the precast block is determined according to the convenience of manual carrying and installation, and is generally about 50 cm. Because the size of the rapid trough precast block is a fixed value, but the length of the side slope is not a fixed value, the cutting of the precast block cannot be avoided in the installation process of the rapid trough precast block. If the rapid trough precast block with the opening is adopted, the opening position of the precast block with the opening needs to correspond to the outlet of the transverse drain pipe, and the upper side and the lower side of the precast block need to be provided with the common precast block without the opening, so that the upper side and the lower side of the rapid trough can be respectively cut in the installation process of the rapid trough. Because the vertical distance between the outlet of the transverse drain pipe and the top surface of the roadbed is a fixed value, the length of the side slope at the upper part of the outlet of the transverse drain pipe is also a fixed value, the size of the prefabricated block of the rapid trough is determined according to the fixed value, so that the cutting of the prefabricated block of the rapid trough at the upper part of the prefabricated block with the opening can be avoided, and the cutting work of each rapid trough can be reduced.
