Abstract
An integrally cast speed hump comprises an upper bearing plate and a lower anchored column; the uniform slopes are formed horizontally from the thickest part to both sides; longitudinal arc anti-slip recesses are formed on an upper surface of the speed hump; length of the recesses is the same as that of the speed hump; and the speed hump is integrally cast. After field installation and trial, the integrally cast speed hump has excellent stability and durability, far exceeds ordinary speed humps, is very suitable for roads where a lot of heavy trucks pass, and can effectively ensure the safety of railway crossings; at the same time, the integrally cast speed hump has very simple installation and small influence on passing vehicles; the speed hump is integrated with the road surface completely after being installed and will not becomes loose due to vehicle collisions, so that shearing stress bore by the fixed column is reduced and the service life of the speed bump is greatly prolonged; due to very firm installation, the problem present in ordinary speed humps that expansion bolts are sheared due to long-term collision of vehicles is solved; traveling speed of the vehicles passing the crossings can be effectively reduced; and the service life of the speed hump is greatly prolonged.
Description
Technical field
The utility model relates to a kind of deceleration strip of guaranteeing the road junction traffic safety, also is applicable to the highway crossing that needs to install deceleration strip.
Background technology
At present the mine railway road car amount of making a slip of the tongue is many, and the high capacity waggon proportion of gross weight above 100 tons is big, speed is fast when passing through in the level crossing, braking distance is long, often breaks the accident of railway railing, even swarms into crossing gate or hurdle door and be in collision with the train and lead to serious accident, as use common deceleration strip to force vehicle deceleration, rate of decay is fast, and is fixing insecure, with high costs with the road surface.
Summary of the invention
The technical problems to be solved in the utility model is: design a kind of monoblock cast deceleration strip, to overcome the deficiency that prior art exists.
The technical scheme that solution the utility model problem is taked is: deceleration strip is made up of the anchor stud of top bearing plate and bottom, and thick is along laterally forming the uniform gradient to both sides; The deceleration strip upper surface is provided with vertical circular arc antiskid groove, and the length of groove is identical with deceleration strip length; Deceleration strip adopts monoblock cast to form.
In the both ends of the surface of deceleration strip, be provided with vertical slope, other corner angle are all done chamfered, prevent to scratch the vehicular traffic tire.
Be to strengthen the shear strength of anchor stud root, the anchor stud below the deceleration strip, root is thick, and one section tapering is arranged downwards, and nethermost one section is even cylinder.
Good effect of the present utility model is: according to the monoblock cast deceleration strip of designing requirement making, the on-the-spot installation of process tried out, and one side is stable, durability is fabulous, considerably beyond common deceleration strip, be highly suitable for the highway that a large amount of heavy-duty cars pass through, can effectively guarantee the safety of level crossing; Installation process is very simple on the other hand, and it is little that highway is crossed car influence, back deceleration strip and road surface is installed becomes one fully, can not collide making deceleration strip loosening because of vehicle, reduces the suffered shear stress of fixed leg, can prolong deceleration strip application life greatly; Owing to install very firmly, got rid of the problem that vehicle long term that common deceleration strip occurs is cut off expansion bolt, can effectively reduce by the road junction Vehicle Speed, prolong deceleration strip application life simultaneously greatly.
Description of drawings
Accompanying drawing is a schematic diagram of the present utility model.
The specific embodiment
As shown in drawings, deceleration strip is made up of with anchor stud 3 top bearing plate face 5 and bottom 6, deceleration strip bearing plate face 5 long 90cm, wide 35cm, and thick thickness is 45mm, thick is along laterally forming the uniform gradient to both sides; Deceleration strip bearing plate face 5 upper surfaces are provided with vertical circular arc antiskid groove 4, groove bosom 3mm, and groove width 20mm, the length of groove is identical with deceleration strip; At the two ends of deceleration strip, vertical 1: 1.1 slope 6 is set, other corner angle are all done chamfered, prevent to scratch the vehicular traffic tire.
It below the deceleration strip bearing plate face 5 anchor stud 3 of 6 long 15cm, anchor stud 3 is cast as integral body with the bearing plate face 5 on deceleration strip top, anchor stud top 5cm is one section cone 2, diameter increases 40mm from 30mm from the bottom to top, one section 1 long 10cm of bottom, diameter is 30mm, to strengthen the shear strength on anchor stud top; 2 anchor stud in the middle of the deceleration strip arrange that between two parties two lateral extent 30cm respectively have 2 anchor stud.
Mounting method of the present utility model is: the deceleration strip that processes is transported to the scene, on the rigid pavement that deceleration strip will be installed, finish the line that the deceleration strip position is installed, mark the position of deceleration strip edge and anchor stud, drill diameter 50mm on the highway cement road surface at first, the hole of dark 150mm, according to sulphur: cement: sand: paraffin=1: (0.3-0.6): (1～1.5): the match ratio of (0.01～0.03) and the preparing process of standard preparation anchoring solution, be poured in anchoring deceleration strip in the hole, and fast deceleration strip is mounted to the tram, can about one minute, reach 100% intensity.Within a short period of time, can open highway, deceleration strip just can come into operation, and effectively guarantees road safety.
