Description

Anti-clogging ecological permeable box culvert

Technical Field

The utility model relates to a precast concrete drainage facility culvert pipe component's institutional advancement technique, especially prevent stifled ecological box culvert that permeates water of silting up.

Background

The box culvert refers to a culvert built by reinforced concrete box pipe joints, and is mainly used in large-scale flood drainage channels, urban sewage pipelines, underground pedestrian channels, motor vehicle underground tunnels and other projects.

The box culvert is composed of one or more square or rectangular sections, and is generally made of reinforced concrete or masonry, but the application of the reinforced concrete is wider, when the span is less than 4m, the box culvert is generally adopted, and for the pipe culvert, the reinforced concrete box culvert is a cheap substitute, and the pier, the upper plate and the lower plate are all poured uniformly.

In the prior art, box culvert construction generally adopts cast-in-place, sets up the bottom in the slot that excavates, pours a layer concrete bed course, will process the on-the-spot ligature of reinforcing bar again, props up centre form and external mold, and great box culvert generally pours the latter half of bottom plate and lateral wall earlier, and ligature lateral wall upper portion and roof reinforcing bar again prop up interior formwork, pours lateral wall first half and roof. And (5) removing the formwork when the concrete reaches the strength required by the design, and backfilling the soil on the two sides of the box culvert.

Most of the existing box culvert structures are closed frame structures, water is easy to accumulate on the surfaces of the box culverts, so that a substance and energy circulation system formed among water, soil and organisms is damaged, and the ecological environment-friendly requirement is not met. If the drainage holes are directly formed in the surface of the box culvert, sundries flow into the drainage pipes along with accumulated water, and the box culvert is easy to block.

However, the related improved technology has fewer publications, and the search finds that:

the novel building materials of shandong tianma limited discloses a prefabricated split type corner box culvert in chinese patent application CN201820423369.7, including ring flange, gas tube, rubber buffer, bleeder, recess, connecting pipe, air-supply line and hollow chamber, the rubber buffer assembly is on gas tube annular side, the gas tube upper end is equipped with the ring flange, and the gas tube lower extreme extends to the box downside, the bleeder is installed at gas tube annular side downside, and this design has realized the supplementary mesh of breaking away silt, the recess is seted up at last box up end, hollow chamber is seted up in last box, the air-supply line assembly is at the inside right-hand member face of recess, and the air-supply line right-hand member extends to hollow intracavity, the air-supply line left end is equipped with the connecting pipe, the connecting pipe sets up in the recess, and this design has realized the purpose that debris swept.

Changchun engineering institute discloses a prefabricated utility tunnel box culvert of assembled in China patent application CN201820565377.5, comprising a base plate, the roof, curb plate and baffle, the spread groove is reserved respectively to the higher authority of bottom plate and curb plate and baffle, pre-buried connecting steel plate below roof and curb plate and the baffle, curb plate and baffle insert in the spread groove on the bottom plate and use the structure to glue and bond with the bottom plate through connecting steel plate below, the roof inserts in the spread groove above curb plate and the baffle through connecting steel plate below and uses the structure to glue and bond with curb plate and baffle.

The existing box culvert is poor in ecological and water permeability consideration. Therefore, the invention of a novel ecological permeable box culvert is needed urgently.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prevent stifled ecological box culvert that permeates water of silt, solve above technical problem.

The purpose of the utility model is realized by the following technical measures: comprises a tenon, a Y-shaped drain pipe, a groove, a box body and a culvert pipe; the middle part of the lower side of the box body is provided with a through hole to form a culvert pipe, the top of the box body is provided with a raised tenon, a concave groove is arranged between two adjacent tenons, at least part of the tenons are provided with Y-shaped drain pipes, the lower ends of the Y-shaped drain pipes are communicated to the culvert pipe, and the upper branches of the Y-shaped drain pipes are respectively provided with openings on the outer walls of two opposite sides of the tenons.

In particular, the tenon is an elongated frustum of a prism.

In particular, the diameter of the lower section of the Y-shaped drain pipe is not larger than the width of the tenon.

Particularly, the middle part of the lower side of the box body is provided with one to four culvert pipes.

In particular, the tenon on at least one side of any groove is provided with a Y-shaped drain pipe.

In particular, the culvert is rectangular, circular, or octagonal.

The utility model discloses an advantage and effect: the water-permeable ecological water.

Drawings

Fig. 1 is a schematic sectional structure diagram of embodiment 1 of the present invention.

Fig. 2 is the outline axial structure diagram of embodiment 1 of the present invention.

The reference numerals include:

tenon 1, Y type drain pipe 2, recess 3, box 4, culvert pipe 5.

Detailed Description

The utility model discloses the principle lies in, and tenon 1 height can be adjusted according to the engineering actual need and set for. After the accumulated water in the groove 3 is filtered or precipitated, the structure design is optimized by matching with the Y-shaped drain pipe 2 through hydrodynamics, the drainage is smoother, the clogging is not easy, and the ecological water permeable device is mainly suitable for engineering with ecological water permeable requirements.

The utility model discloses a: tenon 1, Y type drain pipe 2, recess 3, box 4 and culvert pipe 5.

The present invention will be further explained with reference to the drawings and examples.

Example 1: as shown in the attached figures 1 and 2, the middle part of the lower side of the box body 4 is provided with a culvert pipe 5, the top of the box body 4 is provided with a raised tenon 1, a concave groove 3 is arranged between two adjacent tenons 1, at least part of the tenons 1 is provided with a Y-shaped drain pipe 2, the lower end of the Y-shaped drain pipe 2 is communicated with the culvert pipe 5, and the upper section of the Y-shaped drain pipe 2 is forked and is respectively opened on the outer walls of two opposite sides of the tenon 1.

In the foregoing, the tenon 1 is a long strip-shaped frustum of prism.

In the foregoing, the diameter of the lower section of the Y-shaped drain pipe 2 is not larger than the width of the tenon 1.

In the above, the middle of the lower side of the box 4 is provided with one to four culvert pipes 5.

In the above, at least one side of the tenon 1 of any groove 3 is provided with a Y-shaped drain pipe 2.

In the foregoing, the culvert 5 is rectangular, circular, or octagonal.

The embodiment of the utility model provides an in, components such as tenon 1, Y type drain pipe 2 and box 4 are according to prefabricated technological requirement preparation, and the on-the-spot hoist and mount installation of box culvert, 4 axial concatenation waterproof construction of box accomplish the back, carry out surface construction at last, can lay infiltration bituminous paving or fill out the afforestation according to engineering actual need in the recess 3.

In the embodiment of the utility model, if the permeable asphalt is laid on the surface after the box culvert is installed, the permeable asphalt can play a role in filtering; if the surface of the box culvert needs greening, filling soil into the groove 3, wherein the filling soil is half of the height of the tenon 1, greening is carried out after compaction, part of accumulated water seeps into the soil, and the redundant accumulated water passes through the Y-shaped drain pipe 2 on the side surface of the tenon 1 after precipitation. Accumulated water on the surface of the box culvert flows into the groove 3, is further discharged from the Y-shaped drain pipe 2 after being filtered or deposited and is collected into the culvert pipe 5, and the blockage can be effectively prevented.
