Abstract
Description
Technical Field
[0001] The invention relates to the technical field of highway slope construction, and in particular to a highway slope arch skeleton slipform construction method and a construction device. Background Art
[0002] The greening project of highway slopes is the most severely damaged area. Since some slopes are steep, the erosion of rainwater will cause a large amount of water and soil loss on the slopes. Therefore, the primary function of slope greening is ecological protection, protecting the roadbed, stabilizing the slopes, and restoring the natural ecology of the slopes. Highway slope protection can be roughly divided into two categories, namely engineering protection and plant protection. Engineering protection is mostly rigid protection composed of steel bars and cement, while plant protection is flexible protection. Engineering protection is the basis of vegetation protection. The two types of protection support and penetrate each other. Only by organically combining the two can the purpose of permanent protection, beauty and durability be achieved, and the project cost can be greatly reduced.
[0003] The engineering protection includes two types: triangular frames and arch frames, which form a grid structure through the overlap of the frames. The arch frame has better protection effect. It not only has good water diversion effect but also can leave more areas for greening. At present, most of the arch frames for slope protection are prefabricated and then spliced on the construction site, which requires a large number of transport vehicles for transportation and a large amount of manpower for laying, which seriously interferes with the progress of the construction period. Affected by the terrain of the construction slope, the prefabricated frame has a poor match with the terrain. Long-term erosion by rainwater can easily lead to fracture, damage or landslides. Summary of the Invention
[0004] In order to solve the problem of slow on-site assembly progress of slope protection arch frames and reduce the impact of terrain on the installation and use of arch frames, the present invention provides a highway slope arch frame slipform construction method and slipform device.
[0005] The present invention provides a highway slope arch skeleton slipform construction method and slipform device using the following technical solutions:
[0006] A highway slope arch skeleton slipform construction method includes the following construction methods:
[0007] Step 1: After the highway is paved, the slope formed is positioned and laid out, the construction position and shape of the arch frame are drawn, and a linear slotting device is used to vertically slot along the highway slope, with the slotting direction being from top to bottom;
[0008] Step 2: After the straight line grooving is completed, the arch line grooving device is used to perform arch line grooving along the horizontal direction of the slope. After the arch line grooving, the excess soil and rocks on the surface are cleaned;
[0009] Step 3: Use a linear sliding form device to perform linear skeleton sliding form construction along the opened linear grooves, wherein the linear skeleton sliding form construction is carried out from bottom to top. After the linear skeleton sliding form construction is completed, wait for the linear skeleton to be in a semi-solidified state;
[0010] Step 4: Using an arch line sliding form device to cut grooves along the opened arch line to perform arch line frame sliding form construction, after the arch line frame sliding form construction is completed, excess concrete is cleaned and the linear frame and the arch frame are flattened as a whole;
[0011] Step 5: Use the water retaining strip slipform device to perform water retaining strip slipform construction on the linear frame and arch frame that have completed slipform construction. After the water retaining strip slipform construction is completed, wait for the linear frame, arch frame and water retaining strip to solidify as a whole;
[0012] Step 6: After the straight frame, arch frame and water retaining strip are solidified as a whole, grid bricks are laid in the grid formed between the straight frame and the arch frame.
[0013] By adopting the above technical solution, the arch frame is manufactured and installed by slip-forming at the construction site according to the design shape of the arch frame through the slip-forming process. The slip-forming shape can be adjusted according to the shape of the construction site, avoiding long-distance transportation of the arch frame, and saving the time of handling and installation. The skeleton constructed by slip-forming can form a relatively stable whole, resisting the erosion of the arch frame by rain and the like. The arch frame constructed by on-site slip-forming can better fit the construction surface and form a solid whole with the construction surface. Grooving first and then slip-forming can resist the fluidity of concrete and prevent the slip-forming skeleton from deforming before hardening. The straight skeleton, arch skeleton and water retaining strip are constructed separately to meet the continuity of construction machinery operation and improve construction quality.
[0014] Preferably, the slope surface is leveled before the positioning and laying out in step 1, and larger stones and other debris are removed. The slope surface is sprayed with water before the linear grooving and the water spraying is continued during the grooving process to promptly clean up the soil and rocks that slide down during the linear grooving process.
[0015] By adopting the above technical solution, larger stones and other debris are removed to prevent protrusions from blocking the slipform construction. Water spraying treatment is beneficial to improving the integrity of the soil layer on the construction surface, reducing the loose and broken slope surface caused by subsequent grooving, which affects the slipform construction.
[0016] Preferably, the depth of the arch groove in step 2 is 0.5-0.8 times the depth of the straight groove. After the excess soil and rocks on the surface are cleaned, the miscellaneous soil and rocks in the arch groove and the straight groove are cleaned and the bottom of the arch groove and the straight groove are compacted.
[0017] By adopting the above technical solution, the arch line groove is shallower than the straight line groove, which is convenient for the debris in the groove to be discharged into the straight line groove. During the slipform construction, the top surface of the arch line groove can be slightly higher than the straight line groove, which is convenient for the subsequent construction of the water retaining strip. Compacting the bottom of the arch line groove and the straight line groove is conducive to improving the stability of the soil layer and improving the stability of the base layer of the arch skeleton.
[0018] Preferably, before the linear skeleton slipform construction in step three, a slope collapse test is carried out on the concrete to obtain the concrete collapse time and solidification time, and the maximum speed of the linear slipform is calculated through the collapse time and the slipform length. The linear slipform device performs slipform construction at a speed less than the maximum speed of the linear skeleton slipform during slipform construction.
[0019] By adopting the above technical solution, the collapse test can determine whether the concrete can be shaped on the slope surface, prevent the concrete from collapsing before hardening during slope construction, control the sliding form speed, and prevent the sliding form height from being too high to squeeze the unhardened concrete at the bottom and cause collapse, thereby effectively improving construction quality.
[0020] Preferably, the thickness of the arch frame constructed by the arch line frame slipform in step 4 is the same as the thickness of the straight line frame, the cross-sectional shape of the arch frame is mainly rectangular with a groove near the bottom side, and the cross-sectional shape of the water retaining strip constructed by the water retaining strip slipform in step 5 is trapezoidal, and the bottom is overlapped in the groove on the bottom side of the arch frame.

The chain plate slotting knife can be used for straight slotting, and the slotting depth can be conveniently controlled. The chain plate slotting knife is driven by the linear slotting screw to move from top to bottom along the slope surface on the first support, so that long straight slot excavation can be realized and the soil blocks dug out by the slotting can slide down the slope surface to the bottom for easy cleaning. The linear water spraying device is conducive to reducing the dust raised by the chain plate slotting knife during slotting, and at the same time can improve the adhesion of the soil surface and reduce the loosening and shedding of soil blocks in the soil layer.

The chain-type slotting cutter can be used for straight slotting, easily controlling the slotting depth. Driven by a linear slotting screw, the chain-type slotting cutter moves downward along the slope on the first support, enabling long straight slot excavation. Excavated soil can slide down the slope for easy cleaning. A linear water spray device helps reduce dust raised by the chain-type slotting cutter during slotting, while also improving the surface adhesion of the soil layer and reducing the loosening of soil clods. The second mobile carriage drives the second support, achieving continuous horizontal construction of the arched slot. The spiral slotting cutter can be used for curved slotting, with convenient control of the curve shape in two directions. Complex curves can also be programmed.
