The transport of lime, fly ash and gravel mixes is carried by dump trucks. Due to the limited conditions of facilities in the stadium, the total weight of the transport vehicles should be less than 20t, and the vehicles must have sealed-coverage equipment to prevent dust, prevent spillage, and prevent leakage.
When using manual paving operations, the paved area should be calculated every day. Do not stack large piles, affecting the paving, and the bulldozers can be used to disperse the materials after the materials are supplied. The measuring staff presses the 5mx5m grid to measure points on the spot. Filling and uneven places. If an asphalt concrete paver is used, baseline measurements must be made on both sides of the paving operation, and the paver should be paved under the control of the baseline.
In the sequence of paving for sports track and field venues, the main runway shall be paved first to increase the site operation height, and the protection of the inner ring ditch shall be favorable, and then the two semicircular areas of the field match shall be paved. When various vehicles pass through the gutters, protective measures should be taken to prevent them from shifting and damaging.
In the paving operation, the conditions of the site shall be used to control the imaginary thickness of the lime, fly ash and gravel mixture in order to satisfy the design requirements in real time. It is generally the compacted thickness (designed structure thickness) multiplied by the compaction factor, which is calculated as follows:
H=hK
Where the H-mixing paving thickness (cm);
h—Design structure thickness (compacted thickness) (cm);
K—compaction coefficient r/r1 (manual paving 1.4~1.45, asphalt concrete paving paving 1.15~1.4);
r - dry mass density after compaction (t/m3), r = 2.13 to 2.2 t/m;
r1—Under certain paving, the dry bulk density (t/m3) of the mixture, the artificial paving r1=1.52 to 1.57 t/m, and the mechanical paving r1=1.57 to 1.8 t/m3.
After the paving operation is completed, the artificially paved section shall be inspected. Where the sand and gravel material is concentrated, digging and lifting shall be adopted so that the gravel will be evenly distributed. For places where fines are concentrated, grit-filling methods can be used. At the same time, all inspections are performed. Grids are used to measure the height of the grids and verify that there are no problems. The next roller compaction operation can be started.
When a structural design exceeds a thickness of 20 cm, a layered operation shall be adopted. When the first layer is operated, it shall be carried out according to the standard. After passing the qualification, the mixture shall be blended from the upper layer to be leveled and trimmed. If a thick paving operation is not only difficult to grasp, it also brings difficulties to the next roller compaction work, and it is difficult to achieve compaction density and achieve qualified products.
The sprinkler truck is also known as the spraying car, multifunctional sprinkler, landscaping sprinkler, water tankers, water bowser ,water tank truck ,water truck .The sprinkler is suitable for various pavement washing, trees, green belt, green lawn, roads, construction of factories and mines, high-altitude construction flushing. With water, dust, high, low spray, pesticide spraying, rail and other functions, but also has the function of water transport, water drainage, emergency fire and so on.
CLW GROUP TRUCK Spraying car, also known as multifunctional green sprinkler. For urban road, large plant, army, garden and other units of clean pavement, hygiene, dust, water, spraying pesticides, etc., in order to achieve the role of landscaping.
At the same time can be used for temporary emergency fire sprinkler, each sprinkler is equipped with fire special interface.
Driven by the engine gearbox, gearbox mounted power take-off drive sprinkler pumps, sprinkler pump produces the main driving force, inside the tank of liquid spray out through the network. Self suction height: less than or equal to 7m, sprinkler width: is equal to or more than 20m, maximum range: greater than or equal to 28m; adjusting the pillars, the range is more than or equal to 28m; also can adjust into fog, with a range of more than or equal to 5M.
Before the spray, sprinkle is arranged in front of the duck shaped nozzle or round blunt mouth, mounted behind the open sprinkler nozzle or shower nozzle of cylinder, at the back of the work platform, equipped with water cannons. The rear can also be arranged 8 nozzles (optional) sprinkler is generally used to wash the streets.
CLW GROUP TRUCK Tank production
The production process of automatic production line is divided into: feeding, automatic welding, head spinning forming, the body of a rolling molding and other advanced production processes. The tank material uses high quality carbon steel plate production. Special use cases can also be based on the needs of customers using 304 stainless steel. Tank volume is 4 cubic meters, 5 cubic meters, 6 cubic meters, 8 cubic meters, 10 cubic meters, 13 cubic meters, 15 cubic meters, etc..
Piping system
The pipeline, four three-way ball valve, through the ball valve, filter net, a water outlet (pediment sprinkle, side spray; high side of the shower; work platform with green sprinkler gun).
operating system
Mainly by the engine drive gearbox, gear box on the installation of power driven pump, sprinkler pump, the power of the tank, the liquid inside the tank through the pipe network. Scope of work: from the ceiling height: is equal to or more than 7m, sprinkler width: greater than or equal to 14m, maximum range: greater than or equal to 28m; adjusting the pillars, the range is more than or equal to 28m; also can be adjusted into a mist, with a range of more than or equal to 5M.
Sprinkling pump
CLW GROUP TRUCK Equipped with sprinkler, green spray vehicles high power special sprinkling pump (Weilong pump) and fire joint, with gravity flow valve, with self suction function.
Can be optional configuration: can be installed onto the medicine wheel, drug pumps, tank corrosion and rust, multi-faceted import and joint water, electromagnetic valve, gas dynamic valve and other advanced facilities, to meet the needs of different users.
Cab
The truck cab have one row or double row type , also known as the long head of the cab, the cab short head.
Force taking device
The general sprinkler by Dongfeng, Liberation Series PTO, gas operated, switch operation pulls back force taking gear in meshing position, through the drive shaft drives the pump work, the switch forwards a return, the pump is stopped. Force taking device is installed in the watering car gearbox body side of the equipment, automobile gearbox in general have the installation port and installed on the power device can be through the transmission constant mesh gear rotation to transmit the power out, and then through the driving component and controller to transmit power to the drum pay mix car, and pressure pump
CLW GROUP TRUCK Sprinkler function description:
Sprinkler with duck shaped nozzle or round blunt mouth, mounted behind the open sprinkler nozzle or shower nozzle of cylinder, at the back of the work platform, equipped with water cannons. The rear can also be arranged 8 nozzles (optional).
Sprinkler is generally used to wash the streets, dust and cooling, the sprinkler can be by adjusting the thread of the nozzle change direction and angle of sprinkler spray, water antiaircraft gun can be used for urban and rural landscape and emergency fire.
