How to determine the number of pavers

This is determined according to the matching of paving width and construction efficiency.

In general, the paving width of the paver is controlled at about 4~7m, so the number of pavers in a working face is determined according to the paving width of a working face, and then the number of each working face is added up, which is the total.

Paver is a kind of construction equipment mainly used to spread various materials on the base and surface of expressway. The paving work is completed by the cooperation of various systems, mainly including walking system, hydraulic system and distribution system.

Operating procedures:

A, paver operators must undergo professional training, understand the mechanical performance, structure, maintenance knowledge, master the machine performance, operating essentials and safety matters, and after confirmed by the relevant departments, can operate alone.

2. Before starting the engine, you must check whether the engine oil (engine oil, fuel oil, working oil and lubricating oil) is sufficient, whether the belt on the fan is tensioned, whether there is oil leakage and whether its parts are loose. Check whether all kinds of accessories, accessories and tools needed for the day's work are complete.

Three, after starting the engine, idle running for at least two minutes, check whether the monitoring system instructions are normal.

Four, must command the material truck to accurately unload the material into the machine hopper.

Five, paver before work must get in touch with the leveling personnel around, to ensure that other people are not in the homework, before operation.

Six, when changing from the working gear to the active gear, it must be carried out under the condition of small throttle, complete stop of the machine and stop of all working parts.

Seven, the operator is strictly prohibited to drink and operate, when operating equipment must be dressed neatly, shall not wear slippers, can not have smoking, eating and other acts that hinder safe operation.

Eight, paver after work, all protective devices must be installed in the specified location.

Nine, operating room (Taiwan) must be kept clean, clean up oil and other dirt in time, don't place tools and other items anywhere.

X. When the driver leaves the operating platform, all operating mechanisms must be placed in the "0" position.

Eleven, for hydraulic automatic widening paver widening, we must pay attention to observe the situation nearby, so as not to hurt people and damage equipment.

Twelve, when using liquefied gas tank heating paving, in the case of flameout or fire. , the fuel tank valve must be closed. When the ambient temperature is higher than 200C or the air tank is directly dried by the sun, the air tank must be covered.

Thirteen, after paving, cleaning material conveying, tamping device, stop screed must be placed on the mat, machine parking shall not hinder traffic, and warning signs should be placed. Before turning off the engine, let the engine idle for 5 minutes, then cut off the power supply and lock the instrument panel.

Fourteen, equipment maintenance must be carried out in accordance with the requirements of the manual.

Fifteen, equipment maintenance, must:

(1) The hopper and screed are firmly fixed.

(2) Engine flameout.

(3) When maintaining the hydraulic system, the residual pressure of the hydraulic system must be released.
