Description

High-efficiency hot-melting construction waterproof coiled material paving vehicle

Technical Field

The utility model relates to the technical field of waterproof coiled material construction, in particular to a high-efficiency hot-melting construction waterproof coiled material paving vehicle.

Background

At present, the well-known construction waterproof engineering hot-melting method is generally a construction method for melting a modified asphalt material of a bottom layer of a hot-melting waterproof coiled material by flame heating so as to bond the modified asphalt material with a base surface. The traditional construction process of the hot melting method is a construction method which connects a flame gun with a liquefied gas tank, ignites liquefied gas sprayed by the flame gun after a valve switch of the liquefied gas tank is opened, melts modified asphalt materials at the bottom layer of a hot melting waterproof coiled material by utilizing the temperature of sprayed flame, and then adheres to a base layer, but the traditional construction process of the hot melting method has some defects and hidden dangers, and is specifically as follows:

(1) The quality of manual construction is difficult to ensure.

At present, the waterproof construction quality completely depends on the construction level of workers. However, the construction technology level of workers is uneven, so that a certain gap exists in waterproof construction quality. The concrete steps are as follows: according to the standardized construction requirement, when the waterproof coiled material is constructed by hot melting, an operator is required to hold a flame gun to stand on a construction base surface, so that the gun head is about 30-50 cm away from the base surface and the coiled material surface, the base surface and the coiled material surface are baked in a left-right reciprocating manner, the base surface and the coiled material surface are baked until the bottom surface of the coiled material is black and glossy, the coiled material is rolled in time when asphalt oil waves appear along with the gun head movement, and the coiled material is compacted while hot and exhausted, so that paving is completed. However, in actual construction, the fire and baking time are often difficult to control, and uneven baking of coiled materials is easily caused. The long baking time can lead to perforation of the waterproof coiled material, so that the coiled material loses the waterproof function; the baking time is insufficient, the bottom temperature of the waterproof coiled material cannot reach the hot melting temperature, so that the waterproof coiled material and a base surface cannot be adhered firmly, and particularly, the joint edge of the same-layer coiled material cannot be adhered firmly, and the hidden danger of water seepage is formed after the intersection.

(2) The construction efficiency is low, and the progress is slow, influences the time limit for a project.

The coil construction generally adopts a manual rolling method, namely an operator uses a flame gun to heat the bottom surface of the hot-melt coil, melt asphalt at the bottom, roll and spread the asphalt while the asphalt is hot, and drive out the coil and the air of a base surface to form full adhesion. But the width of the coiled material is 1 meter, the hot melting range of the mouth of the flame spraying gun is limited, an operator needs to move the spray gun back and forth left and right, and the coiled material can be rolled and paved after being completely heated, so that the construction efficiency is low. Meanwhile, in the standardized waterproof construction flow, at least three operators are required to finish the hot-melt paving waterproof coiled material in a cooperative mode, the personnel utilization rate is low, and labor cost saving is not facilitated.

(3) The construction danger coefficient is high.

When the fire gun is constructed, fire power is strong, flame is big, construction safety is poor, improper operation easily causes personal injuries such as scalds, burns to because waterproofing membrane is spread when pasting, the fire gun needs round trip movement operation, and after waterproofing membrane construction is accomplished, rifle head temperature is high, if put at will on the flammable object surface, extremely easily causes job site fire accident, exists very big potential safety hazard.

(4) Low flame heat efficiency utilization rate

The special flame gun for the hot-melt waterproof coiled material often adopts a liquefied natural gas inlet and a gas outlet, when the special flame gun is used, liquefied natural gas at one end of the gas outlet is ignited, when the hot-melt waterproof coiled material is constructed, the flame at the gas outlet end of the flame gun is large in flame and high in temperature, but the flame gun is limited in the hot melting range of the mouth of the flame gun, an operator is required to move the flame gun left and right to bake the coiled material to a molten state, and then the coiled material is paved. In the process, energy is wasted, according to the related data, the heat efficiency utilization rate of the flame gun is only about 30%, if the air outlets are divided into a plurality of rows of small air outlets under the same energy condition, the flame temperature is ensured, the flame size can be effectively reduced, the flame gun can be prevented from moving left and right back and forth, and the combustion efficiency of the liquefied natural gas is fully utilized.

In view of the above problems, a mechanical construction tool is needed that can perform high-efficiency construction, high-quality finishing, low hidden trouble, high energy saving and cost saving for enterprises.
