Description

A kind of multi-functional lobby drainage facility
Technical field
The utility model relates to be related to a kind of road equipment, belong to field of road, especially a kind of multi-functional lobby Drainage facility.
Background technique
Currently, often got the brush-off in road engineering due to " small " that gutter is opposite, since gutter displacement is little, one As do not do the hydrology and water force, often according to front and back section situation, be accustomed to selection standard form of fracture, high speed, Class I highway The bottom width and depth of gutter are not less than 60cm, other standard highways are not less than 40cm.The gutter of same project different sections of highway is often adopted With a kind of form of fracture, the actual conditions such as landform, weather, hydrogeology, multiselect cover board gutter, rectangle gutter are not fully considered Etc. patterns.Gutter design " medelling, mechanization, traditional " is applied, and adaptation to local conditions is lacked, and various reasons cause deep big gutter general Store-through exists, and inevitably results in the wasting of resources, silt deposits in bottom of trench, and deeper gutter brings peace to vehicle, pedestrian Full hidden danger.
The higher underground water of perched water and water level in roadbed and slope soil will affect side slope and subgrade stability, Chang Cai Underground water is reduced with the underdrain of the forms such as french drain, sewer.French drain is used in ditch with the water penetration granular materials of different-grain diameter Paving is filled out in layering, and is wrapped up with geotextiles;Sewer is increased in size on the basis of french drain and sets pipe in bottom of trench or set hole, drainage effect ratio French drain is slightly good.Traditional rubble french drain, sewer collect perched water and underground water in a manner of seepage flow, and moisture is in seepy material sky It is flowed between gap, water flow is in turbulent condition, and charge for remittance effect is poor, and water flow is obstructed, flow velocity is relatively slow, flow is smaller.Backwater and underground The water hydrology is complicated, and underdrain is easy siltation blocking, it is difficult to converge and exclude to designated place.
The charge for remittance of road surface is dropped to, can also be penetrated into inside pavement structure by the seam gaps between road surface and ditch side, Free water into structure sheaf can accelerate ground surface material damage.
To sum up, cutting gutter pumping equipment performance is improved, it is particularly important to improve subgrade and pavement water resistant evil ability.
Utility model content
The utility model is intended to provide a kind of pumping equipment for having both gutter and french drain function, and road surface charge for remittance will not be helped from ditch Seam gaps between road surface are penetrated into inside road surface structare layer, and the multi-functional lobby drainage facility of appearance of a street width is increased.
To achieve the above object, the utility model provides the following technical solutions: a kind of multi-functional lobby drainage facility, including prefabricated Shallow ridges, the prefabricated shallow ridges include several A precast concrete blocks being arranged successively, and the top of A precast concrete block is equipped with transversal Face is trapezoidal shallow trench;The bottom of prefabricated shallow ridges is equipped with precast hollow brick, and precast hollow brick is equipped with multiple groups, is arranged successively, often Group precast hollow brick includes two precast hollow bricks being symmetrical set, and is set in each precast hollow brick there are two symmetrical above and below The circular hole of setting;The left side of prefabricated shallow ridges is equipped with prefabricated zanjon, and prefabricated zanjon includes several B precast concretes being arranged successively Block, it is trapezoidal deep trench that the top of B precast concrete block, which is equipped with cross section,.
Further scheme as the utility model: the bottom surface of the prefabricated shallow ridges covers one layer of cement mortar bedding cushion.
Further scheme as the utility model: the difference in height etc. between the right side ditch side of the prefabricated shallow ridges and road surface In the thickness of road surface.
Further scheme as the utility model: the A precast concrete block and the road multiple groups precast hollow Zhuan Junshiyan Moat is arranged on direction.
Further scheme as the utility model: precast hollow brick top surface and the bottom surface of prefabricated shallow ridges are affixed.
Further scheme as the utility model: the material of the A precast concrete block is C25 concrete, top The depth of shallow trench is 22cm, width 40cm.
Compared with prior art, the utility model has the beneficial effects that the multi-functional lobby drainage facility can be linked as with road surface One, road surface charge for remittance, which quickly collects, to be flowed in gutter, without penetrating into road surface structare layer from the seam gaps between ditch side and road surface Portion, while increasing appearance of a street width.
The utility model overcomes defect and deficiency existing for above-mentioned existing gutter and underdrain, particular for shallow cut short of rain, Be lauched enrichment location, by the research to gutter and french drain, Optimal improvements, make its have both the top drainage of road circle and subdrainage with And expand the effects of clear zone provides fault tolerant workspace for driver, it is worth promoting.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model in embodiment one;
Fig. 2 is the structural schematic diagram of the precast concrete block of the utility model in embodiment one;
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to FIG. 1-2, in the utility model embodiment, a kind of multi-functional lobby drainage facility, including prefabricated shallow ridges 1, it is described Prefabricated shallow ridges 1 includes several precast concrete blocks 11 being arranged successively, and it is ladder that the top of precast concrete block 11, which is equipped with cross section, The shallow trench 2 of shape;The bottom of prefabricated shallow ridges 1 is equipped with precast hollow brick 3, and precast hollow brick 3 is equipped with multiple groups, is arranged successively, every group Precast hollow brick 3 includes two precast hollow bricks 3 being symmetrical set, and sets that there are two right up and down in each precast hollow brick 3 Claim the circular hole 4 of setting;This makes it possible to form a plurality of continuous channel as underdrain using the circular hole of precast hollow brick 3.
Further, the bottom surface of prefabricated shallow ridges 1 covers one layer of cement mortar bedding cushion 8.
Further, the difference in height between the right side ditch side and road surface 21 of prefabricated shallow ridges 1 is equal to the thickness of 21 upper layer of road surface. It by medial sulcus side top reserve with 21 upper layer uniform thickness thickness space of road surface, and 21 material of surfacing makes itself and road surface 21 are linked together, and 21 charge for remittance of road surface, which quickly collects, to be flowed in gutter, without penetrating into road from the seam gaps between ditch side and road surface 21 Inside 21 structure sheaf of face, appearance of a street width is furthermore also increased.
