Description
Technical Field
[0001] The utility model relates to a construction device for grooving a rock slope of a concrete lattice beam. Background Art
[0002] With the excavation and construction of canal waterways in China, square lattice slope protection and reinforcement are widely used in permanent slope structures and are one of the important professional projects for slope support and reinforcement. Most of the lattice beams of square lattice slope protection are cast-in-place concrete structures. In the construction of rock (strong weathering to medium weathering) slopes, generally two construction techniques are adopted in current projects.
[0003] One is slope surface grooving construction. Workers use equipment such as shovels, pickaxes, and pneumatic picks to groove the foundation trench of the lattice beam. The width of the groove is roughly the same as the designed beam size. During the grooving process, the soil is discarded from top to bottom. After completion, the foundation trench is manually trimmed step by step, steel bars are tied, and concrete is poured. A large amount of manpower is required during construction, and the operation efficiency is relatively low. Especially when encountering medium weathering rocks, the progress is slow; the soil needs to be discarded layer by layer. Especially when the slope is relatively high, it needs to be transferred several times. In this method, the concrete and the foundation trench do not need to be backfilled twice, and the integrity is good. Generally, it is the recommended method.
[0004] Another technique is similar to the first one. In order to avoid the over-pouring of concrete caused by over-excavation during the foundation trench excavation, large-scale excavation of the foundation trench is carried out, leaving the width for supporting the formwork on both sides. After the excavation and soil discarding are completed, formwork installation, steel bar tying and other processes are carried out, concrete is poured, the formwork is removed, and the soil on both sides of the lattice beam is backfilled. This method reduces the link of groove trimming and at the same time ensures that the concrete does not exceed the quantity, but increases the processes of formwork installation and removal and the subsequent soil backfilling. It is very difficult to meet the requirements of the original soil for the backfill soil between the lattice and the slope, and it is also very difficult to compact the slope soil.
[0005] Therefore, in view of the above problems, a construction device for grooving a rock slope of a concrete lattice beam is proposed. Content of the Utility Model
[0006] The purpose of the utility model is to provide a construction device for grooving a rock slope of a concrete lattice beam, which has high grooving accuracy and fast construction speed, so as to overcome the existing defects.

[0008] Preferably, the cutting assembly includes a forward extension support arm. The inner wall of the front end of the forward extension support arm is rotatably connected to a saw blade mounting main shaft. Two saw blades are connected to the saw blade mounting main shaft through a saw blade spacing adjustment ring. The saw blade mounting main shaft is connected to the output end of the driving diesel engine through a transmission assembly.
[0009] Preferably, the transmission assembly includes a driving wheel, a driven wheel and a transmission belt. The output shaft of the driving diesel engine is connected to the driving wheel. One end of the saw blade mounting main shaft is connected to the driven wheel. The transmission belt is connected between the driving wheel and the driven wheel.

[0011] Preferably, a shield is arranged above the saw blade at the front end of the forward extension support arm.
[0012] Preferably, a push handle is connected to the rear end of the driving diesel engine.

[0018] The present utility model will be further described below in conjunction with the accompanying drawings.
[0019] As Figure 1-2 shown, a construction device for grooving a rock slope of a concrete lattice beam includes a driving diesel engine 1, a cutting assembly, and a cooling assembly; the cutting assembly is arranged at the front end of the driving diesel engine 1, and the output end of the driving diesel engine 1 is connected to the cutting assembly; the cooling assembly is arranged at the rear side of the driving diesel engine 1 for cutting and cooling the cutting assembly; a moving wheel set 2 is arranged at the lower end of the driving diesel engine 1. A push handle 13 is connected to the rear end of the driving diesel engine 1, which is convenient for pushing and moving.
[0020] Specifically, the equipment drives the saw blade 5 to rotate forward, and a simple slideway is arranged on the slope surface. While the equipment moves forward by itself, the saw blade 5 rotates to cut the soil according to the lattice beam side line. After cutting, the size basically meets the requirements of the designed beam size. At the same time, according to the soil quality, saw blades can be added in the middle to basically cut and break the soil at one time, and the personnel clear the soil in the foundation trench from the top of the slope to the bottom at one time. It achieves the purpose of high grooving accuracy, fast construction speed, and less personnel input.
[0021] Specifically, the cutting assembly includes a forward extension support arm 3. The inner wall of the front end of the forward extension support arm 3 is rotatably connected to a saw blade mounting main shaft 4. Two saw blades 5 are connected to the saw blade mounting main shaft 4 through a saw blade spacing adjustment ring 12. One or two saw blades can also be installed in the middle position according to needs to increase the efficiency of breaking the soil; the saw blade mounting main shaft 4 is connected to the output end of the driving diesel engine 1 through a transmission assembly. The transmission assembly includes a driving wheel 6, a driven wheel 7, and a transmission belt 8. The output shaft of the driving diesel engine 1 is connected to the driving wheel 6, one end of the saw blade mounting main shaft 4 is connected to the driven wheel 7, and the driving wheel 6 and the driven wheel 7 are connected by the transmission belt 8. The rotation of the output shaft of the driving diesel engine 1 drives the driving wheel 6 to rotate. The rotation of the driving wheel 6 drives the driven wheel 7 to rotate through the transmission belt 8. The rotation of the driven wheel 7 drives the saw blade mounting main shaft 4 and the saw blade 5 to rotate for grooving operation. A baffle 11 is arranged above the saw blade 5 at the front end of the forward extension support arm 3 to prevent the sputtering of cut rock and soil particles from hurting people.
[0022] Specifically, the cooling component includes a water tank 9, which is connected to the rear end of the driving diesel engine 1. The water tank 9 is connected with a water pipe 10, and the other end of the water pipe 10 extends above the saw blade 5. The water pipe 10 leads the water tank 9 to the saw blade 5 for cooling the saw blade 5 during cutting.
[0023] Specifically, when grooving along the beam direction, small tracks are laid according to the spacing of the moving wheel sets 2 at the bottom of the driving diesel engine 1 or the equipment walks along the slope upwards. After the laying is completed, the equipment starts cutting upwards from the foot of the slope until the top of the slope or the required position. After the soil structure is completed, the operators use shovels and picks to excavate along the cut side lines, and the dimensions of the grooved wall meet the design requirements.
[0024] The construction device for grooving the concrete lattice beam rock slope drives the saw blade 5 to cut and groove by setting the driving diesel engine 1, with a relatively simple structure and high reliability; the number of saw blades can be adjusted according to actual needs, and the middle saw blades can be added at the same time to improve the rock fragmentation rate; it well solves the problem of overbreak of concrete during the construction of small lattice beam grooving; the overall price is relatively low, with good economy; it is applicable to the structures of grooving construction of small and medium-sized beams with different sizes, especially in the strongly weathered to moderately weathered soil layers, with strong applicability.
