Abstract

The invention discloses a method for arranging a drainage system in the middle of a bidirectional separated road and belongs to road and bridge engineering. According to the method for arranging the drainage system in the middle of the bidirectional separated road, a road surface, an isolation belt, road traffic stone, leakage holes, a water passageway, drainage wells, a drainage pipe and a silt accumulating pit are related. The method for arranging the drainage system in the middle of the bidirectional separated road is characterized in that the road surface of the bidirectional separated road inclines towards the isolation belt located in the middle from the two sides, the drainage system is arranged in the isolation belt, the leakage holes are formed in the road traffic stone opposite to the drainage well and are communicated with the drainage well through the closed water passageway, every two adjacent drainage wells are communicated through the drainage pipe, and the silt accumulating pit is formed in the bottom of the drainage well. Compared with the prior art, the method for arranging the drainage system in the middle of the bidirectional separated road has the advantages that traditional two drainage systems arranged on the two sides of a road respectively are replaced with one drainage system located in the middle of the road, accumulated water flows towards the middle from the two sides of the road to be drained, and no hollow structure exists in a roadbed below the road surface; no well pit and no well lid exist on the road surface; no accumulated water exists on the two sides of the road, so that pedestrian and facilities on the two sides of the road are not affected; the density of the roadbed is balanced, and the road surface is smooth and unblocked; the road construction cost is reduced, both the road capacity and the traffic capacity are improved, the road is more user-friendly, safer and more environmentally friendly, and thus the method for arranging the drainage system in the middle of the bidirectional separated road has extremely high application and popularization value.

Description

The mid-method of two-way separation road drainage system

One, technical field:

The invention belongs to road and bridge engineering, specifically a kind of mid-method of two-way separation road drainage system.

Two, background technology:

Road under prior art, middle high, both sides are low, and drainage system is arranged under the road surface of both sides or outside, road surface is its basic model.There is many defects and deficiency in this pattern: 1, drainage system is arranged at road both sides, and a road need be built the same drainage system of two covers, the repeated construction increase cost of building the road.2, high in the middle of road, both sides are low, and precipitation is collected row with other waters and rushes down to both sides by centre, and at city and the dense section of personnel, the standing slow lane in main road both sides and sidewalk, do not establish slow lane and sidewalk, and pedestrian and slow train are also advanced in roadside, both sides.Though Drainage Design is pursued smooth and easy quick, collect to dredge and flow through the recessed uneven Chu Rengxianman of Cheng Hekeng road ponding, unfavorable pedestrian and slow train are current, and vehicular traffic is easy low-priced muddy water also, causes the discontented even dispute of passerby's accumulated rancour.3, in the city of establishing bus routes, the multidirectional extension in bus station expands, and it is hollow that easier ponding becomes, and when bus could not or can not be near platform, often makes troubles to the passenger that gets on or off the bus.4,, in city, when drainage system is arranged under road surface, road both sides, need to be interrupted catch pit being set and configuring well lid.Because vehicle rolls, this often occurs subsiding with regard to the wellblock of weak foundation, and well lid is cracky also.More there is immoral person to steal.Form road trap.The car event of hurting sb.'s feelings of ruining for this reason causing is of common occurrence.5, road drainage well needs regularly and before flood to dig clearly dredging.It digs clearly process and clears out thing all affects the instant current and road health of road.6,, in city, it is to keep one of clean important way in road surface that high-pressure watercart washes away road surface.High-Pressure Water splashes from inside to outside, and roadside pedestrian and facility are all become to no small negative effect.7, in the high-grade highway section away from cities and towns, road is above ground level, both sides Cheng Po often, need carry out precipitation water conservancy diversion and bank protection and dispose, and has increased the cost of building the road, and has increased greening difficulty.8, isolation strip is in greening mode situation, when precipitation too much exceeds greening pool ability to arrange jobs, and the whole road surface of the normal pollution of excessive muddy water.

Three, summary of the invention:

The object of the invention is for above problem and defect, provide a kind of roadbed more firm, road surface is cleaner and tidier, and function is more humane, and building costs is lower, and maintenance is a kind of mid-method of two-way separation road drainage system more easily.

The object of the invention is to be achieved through the following technical solutions:

A kind of mid-method of two-way separation road drainage system, comprise road surface, isolation strip, curb, leakage empty hole, sluice, catch pit, gutter and the long-pending hole of becoming silted up, it is characterized in that two-way separation pavement of road is tilted by two side direction intermediate isolating bands, drainage system is constructed in isolation strip, the curb relative with catch pit arranges leakage empty hole, leakage empty hole communicates with catch pit by the sluice of sealing, catch pit is the vertical of building in the middle of isolation strip, between adjacent drainage channel well, communicate by gutter, catch pit bottom arranges the long-pending hole of becoming silted up.

The mid-method of two-way separation road drainage system of the present invention has simple in structure, and build need not be updated the equipment, and technical standard changes few, uses more humanely, and the feature such as maintenance is more convenient, has following remarkable advantage in addition.

1, two-way separation road drainage system is mid-, and the drainage system that makes to be divided into road both sides is merged into a set of, has reduced workload, has reduced build cost, and disposes convenience is provided for the later stage of catchmenting.

2, in drainage system, be placed in isolation strip, reduced the cavity structure under functional surface.Well lid on road surface or well grate, make roadbed more balanced, and road surface is more smooth, current more smooth and easy.

3, in drainage system, be placed in outside functional surface, well lid or well grate are not rolled by powerful impact and gravity, can all adopt concrete or other cheap materials to manufacture, can stolen or damage formation road trap.Do not exist the sagging formation of wellblock pressurized hole recessed, more smooth-going yet, mean longitude Ji, safer, more environmental protection.

4, surface gathered water is flowed and is collected by both sides centrality, the pedestrian who walks about in rainy day little effect both sides.Upper and lower bus does not have the puddles of water and intercepts.It is few that greenbelt overflows muddy water contamination road area.Sprinkling truck washes away road surface little effect pedestrian and road side facility.Road bank protection washes away without crossing water, is convenient to be absorbed in greening.

5, drainage system safeguard, dredging, dig clearly wait activity in isolation strip, carry out, safe ready, do not affect road surface pass through function, clear out thing little effect view and road health.

In sum, the mid-method of two-way separation road drainage system of the present invention, can make up and avoid numerous deficiencies and the defect of prior art, reduce the cost of building the road, improve the traffic capacity and current quality, safety and environmental protection, people-oriented, thereby have good value for applications.
