Abstract

The present invention provides a vertical cement slurry spraying device and a paver with the device and applications thereof. The vertical cement slurry spraying device mainly includes a cement box. The pipeline in the cement box extends out of the box, circles around the paver and returns to the cement box. The pipeline consists of a pipe and a hose. The hose can be bent according to the spraying position, and the position of the hose on the paver can be adjusted to fit the paver. The vertical cement slurry spraying device can be installed on the paver to spray cement slurry on the roadbed while paving, avoiding cement slurry agglomeration and solidification caused by spraying first and then paving, eliminating the time difference between paving and spraying, and ensuring the adhesion of the base structure. The cement box is provided with a self-circulating pipeline, and a plurality of nozzles in different directions are installed on the self-circulating pipeline. The cement slurry is ejected from the nozzle to form a vortex, which continuously stirs the cement slurry to keep the cement slurry mixed evenly and not sticky and solidified.

Description

Technical Field

[0001] The invention belongs to the field of highway construction equipment, and in particular relates to a vertical cement slurry spraying device, a paver with the device and applications thereof. Background Art

[0002] With the rapid development of highway construction in the current society, road reconstruction and expansion work occurs from time to time. Under the influence of this national condition, the splicing of new and old roads is particularly important. However, in the process of combining the new and old roadbeds, due to the limitations and differences of practice and various factors, some large and small problems will arise in the process of combining. Therefore, the docking of the new and old roadbeds is a very important task.

[0003] In order to prevent and reduce the gaps and various road surface failures at the junction of the new and old roadbeds, the "reverse excavation construction process" is usually adopted. This construction process requires "cement slurry" with a water-cement mixture ratio to bond and reinforce the joints to increase the overall structural strength between layers. At present, the work of brushing and spraying cement slurry on the roadbed steps is done manually, which is very inefficient and has problems such as uneven brushing, which brings certain troubles to the construction progress.

[0004] At present, cement slurry spraying machines have been used to replace manual spraying, such as the application document with application number 201820073938.X, which mainly realizes the function of spraying cement slurry through various structural combinations on the automobile body.

[0005] However, the above device has the following problems:

[0006] (1) It must be independently towed by a tire dump truck, which is a special vehicle for special use. The road trench depth of the "reverse excavation construction process" is about 670mm, and it is inconvenient for a tire dump sprayer to go up and down the road trench;

[0007] (2) There is a time lag after the dump truck sprays the cement slurry. When the paver spreads the cement slurry, it agglomerates and solidifies early, and the characteristics of the cement slurry cannot be well guaranteed. This affects the adhesion between the base structures and the structural strength of the roadbed. Summary of the invention

[0008] The embodiments of the present invention provide a vertical cement slurry spraying device and a paver having the same and their applications, the first purpose of which is to solve the problem that the existing vertical cement slurry spraying device must be independently towed by a truck, which makes it inconvenient to move up and down the road trough; the second purpose is to solve the problem that the existing spraying device and the paver cannot perform paving work synchronously, and there is a time difference that causes poor adhesion and low structural strength between the base structures.

[0063] Reference Figure 4 , discharge the remaining mixture: close valve No. III 1003 and valve No. IV 1004, open other valves, start the paver, drive the motor to run and drive the vertical mud pump 2 to run, the inlet of the vertical mud pump 2 sucks the cement slurry in the cement tank 1, the cement slurry is discharged from the outlet of the vertical mud pump 2 and flows through the No. 1 pipeline 901, the No. 2 pipeline 902 and the No. 3 pipeline 903 in sequence, and is divided into two paths at the outlet of the No. 3 pipeline 903, one path enters the No. 13 pipeline 913 through the No. 1 hose 1201 and the No. 12 pipeline 912 in sequence and sprays out the cement slurry through the second nozzle 1102, and the other path enters the No. 13 pipeline 913 through the No. 4 pipeline 904, the No. 2 hose 1202 and the No. 14 pipeline 914 in sequence, and the two paths spray out the cement slurry in the No. 13 pipeline 913 through the second nozzle 1102, and the cycle continues until the cement slurry in the cement tank 1 is emptied;

[0065] like Figure 1 or Figure 2 or Figure 3 As shown, a plurality of first nozzles 1101 are provided in the cement box 1, and the spraying directions of the plurality of first nozzles 1101 are different. The suction port and the discharge port of the vertical mud pump 2 are both located at the bottom. The first nozzles 1101 with different directions are combined with the discharge port at the bottom of the vertical mud pump 2, and the discharged cement slurry forms a vortex and sprays the inner wall of the cement box 1, thereby playing the role of mixing and stirring the cement slurry.

[0066] It should be noted that the vertical mud pump 2 does not need to be equipped with a separate power device, but instead uses the power device of the paver to provide power for the vertical mud pump 2 as a power source for pumping cement slurry.

[0067] All valves can be used together to adjust the cement slurry injection flow rate, adjust the flow direction of the cement slurry and the pipes it passes through, etc.

[0068] In particular, a certain proportion (the proportion is adjusted according to the needs of the site) of mud mixture needs to be manually poured into the cement box 1 in advance, and the cement slurry of the vertical cement slurry spraying device is cyclically sprayed, a part of the cement slurry is sprayed on the roadbed, and the remaining part of the cement slurry is returned to the cement box 1, and then sucked and sprayed out by the vertical mud pump 2 after being stirred and mixed, and the cycle is continuous. The remaining amount of cement slurry in the cement box 1 is observed, and cement slurry is added in time as needed to avoid uneven spraying caused by insufficient remaining amount.

[0069] In this embodiment, the vertical cement slurry spraying device is suspended on the paver, which is convenient for disassembly and installation, and the cement spraying function is carried out simultaneously with the pavement paving work, ensuring the interlayer adhesion between the paving material and the cement slurry, avoiding the cement slurry from clumping and solidifying caused by spraying first and then paving, and eliminating the time difference between paving and spraying.
