Abstract
The utility model relates to the technical field of underground coal mine transport road construction, in particular to an underground coal mine rubber-wheel vehicle main haulage roadway road pavement structure. The pavement structure comprises strip-shaped steel rib stone plates with the thicknesses of 300mm, the strip-shaped steel rib stone plates adhere to the ground through cement bonding layers, the width direction of the strip-shaped steel rib stone plates is the same as the motion direction of rubber-wheel vehicle wheels, the horizontal distance between the strip-shaped steel rib stone plates is 100mm, the row distance between the strip-shaped steel rib stone plates is 50mm, and the distance between each strip-shaped steel rib stone plate close to a roadway side wall and the corresponding roadway side wall is 100mm. Due to the adoption of the underground coal mine rubber-wheel vehicle main haulage roadway road pavement structure, the ground and the roadway side walls are less pressed, an underground coal mine rubber-wheel vehicle main haulage roadway is prevented from being integrally damaged, potential safety hazards are effectively avoided, transport efficiency is improved, and transport time and cost are reduced. The underground coal mine rubber-wheel vehicle main haulage roadway road pavement structure is suitable for reconstruction engineering of all kinds of coal mines for rubber-wheel vehicle transport and country roads.
Description
Technical field
The utility model relates to transport routes technical field of construction under coal mine, specifically rubber-tired cart main haulage roadway road pavement structure under a kind of coal mine.
Background technology
At present, the rubber-tired cart main haulage roadway under coal mine is all to adopt with steel concrete to lay the thick road structure of 300mm.This structure is adopting, in the pick process, and its road is subjected to the impact of geostatic stress and transportation gravity, is very easy to distortion impaired, to underground work, causes potential safety hazard.
Summary of the invention
The utility model, in order to solve the defect that under existing coal mine, rubber-tired cart main haulage roadway road structure exists, provides rubber-tired cart main haulage roadway road pavement structure under a kind of mine.
The utility model is achieved through the following technical solutions: rubber-tired cart main haulage roadway road pavement structure under coal mine, described paving structure comprises the bar shaped reinforcing bar slabstone that 300mm is thick, bar shaped reinforcing bar slabstone is by cement-bonded layer and ground bonding, the width of bar shaped reinforcing bar slabstone is identical with the direction of motion of glue wheel, spacing between bar shaped reinforcing bar slabstone is 100mm, array pitch is 50mm, near the bar shaped reinforcing bar slabstone of lane side and the distance between the side of lane, is 100mm.
The utility model considers quiet bearing capacity and the dynamic bearing capacity of bar shaped reinforcing bar slabstone, thinks that its thickness is that 300mm is suitable, and described quiet bearing capacity is relevant to static rubber-tired cart, plant equipment, and dynamic bearing capacity is relevant to speed, the acceleration of rubber-tired cart.
Spacing between bar shaped reinforcing bar slabstone is 100mm, and array pitch is 50mm, near the bar shaped reinforcing bar slabstone of lane side and the distance between the side of lane, is 100mm.The utility model utilizes the gap of paving structure to have the characteristics of retractility, by bar shaped reinforcing bar slabstone, carries out pressure transfer, has reduced the pressurized of ground and lane side.
Adopt rubber-tired cart main haulage roadway road pavement structure under coal mine, reduced the pressurized of ground and lane side, avoided glue wheel main haulage roadway road to be damaged on the whole, effectively stopped potential safety hazard, improved conevying efficiency, reduced haulage time, reduced cost, be applicable on the various metalliferous mine and backroad improvement project of glue wheel transportation.
Description of drawings
Fig. 1 is the structural representation of rubber-tired cart main haulage roadway road pavement structure under coal mine.
In figure: 1-bar shaped reinforcing bar slabstone, the cement-bonded Ceng，3-of 2-lane side, a-spacing, b-array pitch.
The specific embodiment
Rubber-tired cart main haulage roadway road pavement structure under coal mine, described paving structure comprises the bar shaped reinforcing bar slabstone 1 that 300mm is thick, bar shaped reinforcing bar slabstone 1 is by cement-bonded layer 2 and ground bonding, the width of bar shaped reinforcing bar slabstone 1 is identical with the direction of motion of glue wheel, spacing a between bar shaped reinforcing bar slabstone 1 is 100mm, array pitch b is 50mm, near the bar shaped reinforcing bar slabstone 1 of lane side 3 and the distance between lane side 3, is 100mm.
During concrete the use, the gradient of described main haulage roadway road ground can not be greater than 7 °, the pressure on ground in the time of can effectively reducing to transport.
