[0002] Highway subgrade construction is a fundamental part of road construction and plays a very important role in the entire highway project. Before the subgrade is compacted, it needs to be aired or watered to rationalize the moisture content of the subgrade. The purpose of watering before subgrade compaction is to ensure that the lower structural layer is moist and prevent it from absorbing moisture from the upper layer during the rolling process, causing the moisture content of the upper layer to drop and fail to reach the optimal moisture content, thereby affecting the compaction degree. In the construction of bridge and tunnel subgrades in current highway projects, the sprinklers used mostly use nozzles to spray water in a mist form, so that the sprayed water falls on the ground. Most highway subgrade construction is located outdoors. When the outdoors is windy, the force of the wind will change the trajectory of the water flow, causing the water droplets that should have fallen in the designated area to deviate from the direction, resulting in uneven and offset spraying range. This will result in some areas not receiving sufficient water, while other areas receiving excessive water, thus affecting the moisture content of the subgrade. Utility Model Content

[0020] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
[0021] Example 1
[0022] A sprinkler for roadbed construction described in this embodiment, such as Figure 1 、 Figure 2 and Figure 4 As shown, it includes a water storage tank 5, a water inlet for adding water is provided on the top of the water storage tank 5, a sealing cover for sealing the water inlet is installed at the water inlet, and the water to be sprayed is stored in the water storage tank 5;
[0023] A plurality of wheels 8 are installed at the bottom of the water tank 5. In this embodiment, four sets of wheels 8 are used. The four sets of wheels 8 are distributed at the four corners of the bottom of the water tank 5, so that the water tank 5 can be moved by the wheels 8. Of course, the number of wheels 8 can also be two, three, etc. according to actual conditions.
[0024] The water tank 5 is fixed with a traction buckle 7, which is connected to a traction vehicle through the traction buckle 7, so that the traction vehicle can drive the water tank 5 to move;
[0025] The visor 1 is fixed on the upper and lower ends of the visor 1 so that the visor 1 is lifted up and down, and the visor 1 is lifted up and down, and the visor 1 is lifted and down, and the visor 1 is lifted and down.
[0026] To further explain, Figure 3 and Figure 6 As shown, the present embodiment preferably includes a hydraulic cylinder 13, a first mounting plate is horizontally fixed on the side wall of the water tank 5, a second mounting plate parallel to the first mounting plate is horizontally fixed on the side wall of the shielding cover 1, the hydraulic cylinder 13 is vertically located between the first mounting plate and the second mounting plate, and the two ends of the hydraulic cylinder 13 are respectively fixed on the first mounting plate and the second mounting plate; the hydraulic cylinder 13 is an existing product, and its structure includes a cylinder barrel and a cylinder head, a piston and a piston rod, and the extension and reciprocating motion of the piston rod is completed. The fixed end of the hydraulic cylinder 13 is mounted on the first mounting plate, and the extension end of the hydraulic cylinder 13 is fixed on the second mounting plate. The extension and retraction of the hydraulic cylinder 13 pushes and pulls the second mounting plate up and down, so that the second mounting plate drives the shielding cover 1 to move up and down, and the shielding cover 1 is adjusted to different lengths by extending and retracting the hydraulic cylinder 13. The height of the shielding cover 1 can be adjusted to adjust the distance between the shielding cover 1 and the ground. The shorter the distance between the notch of the shielding cover 1 and the ground, the smaller the gap for wind to pass through, and thus the smaller the influence of wind on the water mist. When the water spraying is completed, the shielding cover 1 can be raised to keep the shielding cover 1 away from the ground, so that the shielding cover 1 will not be damaged by the raised mud or stones on the ground during the transfer process. This solution as a whole constitutes an adjustment component for adjusting the height of the shielding cover 1 up and down; of course, the adjustment component can also use an electric push rod, a first fixing plate is horizontally fixed on the side wall of the water tank 5, and a second fixing plate parallel to the first fixing plate is horizontally fixed on the side wall of the shielding cover 1. The electric push rod is vertically located between the first fixing plate and the second fixing plate, and the two ends of the electric push rod are respectively fixed on the first fixing plate and the second fixing plate.
[0027] The hood opening of the shielding hood 1 faces downward, and a wind-blocking curtain 10 is provided at the hood opening of the shielding hood 1 for blocking the wind at the gap below the shielding hood 1. The wind-blocking curtain 10 includes a mounting frame, which is fixed along the edge of the hood opening of the shielding hood 1. A plurality of wind-blocking rods are vertically fixed to the bottom of the mounting frame. The wind-blocking rods are made of materials such as rubber, silicone, and latex. These materials have a certain degree of elasticity. When the bottoms of some wind-blocking rods touch the uneven ground, they can bend and deform to adapt to the convex or concave ground, and can quickly recover when encountering a flat ground; Figure 1 、 Figure 3 and Figure 6 As shown, all the choke rods are distributed along the bottom of the mounting frame, and the positions of all the choke rods are staggered, so that the gap between the shielding cover 1 and the ground is covered by dense choke rods. When the wind blows through the dense choke rods, the choke rods will act like a barrier, slowing down the wind speed and dispersing the wind direction, reducing the impact of the wind on the falling water droplets; of course, the wind choke curtain 10 can also use bristles, and the bottom of the shielding cover 1 is fixed with a mounting frame, and the bottom of the mounting frame is vertically fixed with dense bristles;
[0028] A water distribution pipe 15 is fixed horizontally in the shielding cover 1. A plurality of nozzles with nozzles facing the cover opening are fixed on the water distribution pipe 15. In this embodiment, five nozzles are used and are evenly distributed along the length of the water distribution pipe 15. The water in the water distribution pipe 15 is sprayed downward in a mist form through each nozzle, so that the sprayed water droplets fall to the ground from the cover opening below. The shielding cover 1 shields all the nozzles and the water sprayed by the nozzles, which can prevent wind from blowing on the sprayed water droplets and prevent the force of wind from changing the trajectory of the water droplets, so that the water can be evenly sprayed in the designated area.
[0029] To further explain, Figure 1 、 Figure 2 and Figure 3As shown, the present embodiment preferably includes a first water pump 6, the first water pump 6 is installed on the water tank 5, and a first connecting pipe communicating with the water inlet of the first water pump 6 and the interior of the water tank 5 is connected between the two, and a first water delivery pipe 3 communicating with the water outlet of the first water pump 6 and the water distribution pipe 15 is connected between the two; when in use, the first water pump 6 is started, and the first water pump 6 pumps out the water in the water tank 5 through the first connecting pipe, so that the water enters the first water pump 6 and is pressurized, and then is delivered to the water distribution pipe 15 through the first water delivery pipe 3. The water in the water distribution pipe 15 is sprayed out in a mist form from each nozzle under the action of the water pressure; this solution as a whole constitutes a method for pumping water from the water tank 5 is transported to the water delivery component at the nozzle; of course, the water delivery component can also use an air pump, which is installed on the top of the water tank 5, and the air outlet end of the air pump is connected to the water tank 5. A water delivery pipe is provided between the water tank 5 and the water distribution pipe 15, and one end of the water delivery pipe is connected to the water distribution pipe 15. The other end of the water delivery pipe is fixed to the bottom of the water tank 5 and communicates with the interior thereof. Except for the water delivery pipe, the remaining gaps or holes in the water tank 5 are provided with sealant or sealing gaskets. When in use, air is injected into the water tank 5 by the air pump to increase the air pressure in the water tank 5, thereby pushing the water in the water tank 5 from the water delivery pipe into the water distribution pipe 15 through the air pressure.
[0030] To further explain, Figure 3 、 Figure 4 and Figure 6As shown, the present embodiment preferably includes a second water pump 11, and a collecting tank 14 is fixed on the inner cover wall of the shielding cover 1. The notch of the collecting tank 14 faces upward, and the collecting tank 14 is in the shape of a square ring, surrounding all the inner cover walls of the shielding cover 1; part of the water sprayed by the nozzle will adhere to the inner cover wall due to the deviation of the direction of the water droplets splashing during spraying. After the water attached to the inner cover wall is gathered into a larger water flow, it will flow down along the inner cover wall. When a large amount of water falls on the ground at a single position, it is bound to cause the moisture content of the ground in this area to be too high. In the present embodiment, the water can fall into the collecting tank 14 when it slides down. The water on the inner cover wall is collected by the collecting tank 14; the second water pump 11 is installed on the water storage tank 5, and a second connecting pipe communicating with the water outlet of the second water pump 11 and the inside of the water storage tank 5 is connected to the second water supply pipe 2 communicating with the water inlet of the second water pump 11 and the collecting tank 14. A filter cartridge 12 for filtering the water discharged from the second connecting pipe is fixed on the top of the water storage tank 5. The filter cartridge is an existing product, which is a cylindrical element used for filtering. Common filter materials of the filter cartridge include wood pulp fiber filter paper and spunbond polyester fiber non-woven fabric, among which polyester non-woven fabric can be used for filtering. The second water pump 11 is turned on to pump out the water collected in the collecting tank 14 through the second water pipe 2, and after pressurization, it is discharged into the water storage tank 5 through the second connecting pipe. The recovered water will fall into the filter cartridge 12 when discharged from the second connecting pipe, and the water recovered in the water storage tank 5 is filtered by the filter cartridge 12 to prevent the recovered water from containing impurities, thereby realizing recycling and avoiding waste of resources. This solution as a whole constitutes a recovery component for recovering the water attached to the inner cover wall into the water storage tank 5; of course, the recovery component can also Four water diversion plates are used, and the four water diversion plates are fixed on the four inner walls of the shielding cover 1 in an inclined shape. Drinking grooves are opened on all water diversion plates along the length direction. A collection box is fixed on the side wall of the shielding cover 1. A water pipe is connected between the lower end of all water diversion plates and the collection box. When in use, the water on the inner wall of the shielding cover 1 will slide onto the water diversion plate and move along the water diversion groove toward the water pipe and enter the water pipe. The height of the collection box is lower than that of the water diversion plate, so that the water will be transported to the collection box after entering the water pipe. The water in the collection box is subsequently filtered and poured into the water storage tank 5, thereby realizing recycling.
[0031] In actual use, first, the traction buckle 7 is used to connect the sprinkler to the traction vehicle so that the traction vehicle can drive the sprinkler to move. When the hydraulic cylinder 13 is started, the contraction of the telescopic end of the hydraulic cylinder 13 pulls the second mounting plate to move, so that the second mounting plate drives the shielding cover 1 to move downward. The distance between the shielding cover 1 and the ground is adjusted according to the actual flatness of the ground so that the bottoms of all the wind-blocking rods are in contact with the ground. Then, a water pump (6) is started. The first water pump 6 pumps out the water in the water tank 5 through the first connecting pipe. After the water enters the first water pump 6 and is pressurized, it is transported to the water distribution pipe 15 through the first water supply pipe 3. Under the action of the water pressure, the water in the water distribution pipe 15 is sprayed out from each nozzle in a mist form. The sprayed water droplets fall to the ground from the hood opening below. When the traction vehicle drives the sprinkler to move, it can spray water along the moving route. In the process of moving water spraying, the shielding cover 1 The cover 1 can block all nozzles and the water sprayed from the nozzles to prevent wind from blowing on the sprayed water droplets, and the wind-blocking curtain 10 can block the gap between the shielding cover 1 and the ground. All the wind-blocking bars on the wind-blocking curtain 10 can slow down the wind speed and disperse the wind direction, reduce the impact of the wind on the falling water droplets, and prevent the force of the wind from changing the trajectory of the water droplets, so that the water can be evenly sprayed in the designated area. Some of the water attached to the inner cover wall will fall into the collection tank 14 when it slides down. The second water pump 11 is turned on and the second water pump 11 pumps out the water collected in the collection tank 14 through the second water pipe 2. After pressurization, it is discharged into the water storage tank 5 through the second connecting pipe. The recovered water will fall into the filter cartridge 12 when it is discharged from the second connecting pipe. The water recovered in the water storage tank 5 is filtered by the filter cartridge 12 to prevent the recovered water from containing impurities, thereby realizing recycling and avoiding waste of resources.
