Description

Technical Field

[0001] The invention belongs to the field of rapid flow trough construction equipment in drainage engineering, and in particular relates to a rapid flow trough cast-in-place construction device. Background Art

[0002] In highway engineering, rapids are often built on slopes to drain water and slow down the flow of water, which plays a great role in protecting the roadbed. The role of rapids also reflects the construction environment and requirements of rapids. Construction needs to be carried out on slopes. In order to adapt to the slope well, the existing technology directly casts concrete on the slope. The specific construction process is measurement and layout, foundation excavation, template installation, and concrete pouring. Since the template of the rapids is tilted as a whole, if the top is not blocked in time during pouring, the concrete will flow downward under the action of gravity. When the closed template is built and the concrete is poured directly from the top for pouring, the whole cannot be vibrated evenly. Summary of the invention

[0035] The steps of pouring the rapids trough using the above device are:

[0036] Step 1: dig a foundation pit 1 on the slope. The shape of the foundation pit 1 is an inverted trapezoid with a wide upper part and a narrow lower part. Compact and reinforce the side walls and bottom of the foundation pit 1.

[0037] Step 2: Determine the positions of the two outer molds 4 according to the size of the rapid flow trough 2, splice the outer molds 4 of the size required for the installation of the outer mold units, and fix the two outer molds 4 in the foundation pit 1 through the inclined support plate, and set embedded steel bars between the two outer molds 4, so that the integrity between the concrete rapid flow trough 2 and the slope to be poured later is strengthened, and the inner mold units 6 are connected according to the size of the rapid flow trough 2 to form an integral "U"-shaped inner mold 3, and placed between the two outer molds 4;

[0038] Step 3: The end mold 8 is fixedly connected to the ends of the two outer molds 4 and the "U"-shaped inner mold 3. At this time, the position of the end of the "U"-shaped inner mold 3 relative to the position between the two outer molds 4 is fixed;

[0039] Step 4: Install the capping mold 5 from bottom to top, install one capping mold 5, and cast a section of the rapid flow trough 2 until the casting of the entire rapid flow trough 2 is completed;

[0040] Step 5: After curing and standing still as required, first disassemble the capping mold 5, then disassemble the "U"-shaped inner mold 3 and the outer mold 4, and finally backfill and tamp the foundation pit 1 on both sides of the rapids trough 2 to complete the pouring of the rapids trough 2.

[0041] Working principle: When installing the capping mold 5, the connecting hook 12 of the bottom capping mold 5 is snapped together with the connecting bayonet 9 on the end mold 8. After the connecting hook 12 is aligned with the connecting bayonet 9, it can be rotated around the end mold 8. When the outer hook 15 on the capping mold 5 contacts the flange 17 of the outer mold 4, and the inner hook 16 contacts the snap-on corner block 11, when the lower surface of the capping mold 5 is completely in contact with the upper surface of the outer mold 4 and the upper surface of the "U"-shaped inner mold 3, under the action of the torsion spring, the outer hook 15 contacts the flange of the outer mold 4. 17 is clamped, and the inner clamping hook 16 is clamped together with the clamping corner block 11; after the installation of the lowest cover mold 5, a cavity to be poured is formed between the lowest cover mold 5 and the end mold 8, the outer mold 4 and the "U"-shaped inner mold 3, and then pouring is carried out directly. When the concrete plane is flush with the upper edge of the cover mold 5, the pouring is stopped and the concrete is vibrated, and then the next cover mold 5 is installed. When the next cover mold 5 is installed, its connecting hook 12 is passed around the supporting cross bar 10 and passed through the connecting port 61, as shown in FIG. Fig. 9As shown, at this time, the trigger rod 14 is in contact with the trigger plate 20, and the two ends of the trigger rod 14 are in contact with the blocking rod 26, and then the capping mold 5 is rotated around the supporting cross bar 10, and the trigger rod 14 drives the trigger plate 20 and makes the trigger plate 20 and the rotating rod 18 rotate together. At this time, the rotating rod 18 drives the shift fork 19 to rotate but does not trigger the sliding. The spring 23 is in a natural state at this time. When the next capping mold 5 rotates to the same plane as the previous capping mold 5, the outer hook 15 on the next capping mold 5 is clamped together with the flange 17 of the outer mold 4, and the inner hook 16 is clamped together with its corresponding clamping angle block 11. At the same time, the trigger rod 14 enters the limit groove 25 through the entry notch 27. Subsequently, the segment is poured with concrete, and after the pouring is completed, the next capping mold 5 is installed in the above-mentioned manner and poured until the pouring of the entire rapids trough 2 is completed.

[0042] In the above process, the adjustment blocks at both ends of the connecting hook 12 can also correct the position of the "U"-shaped inner mold 3 relative to the two outer molds 4 as they rotate to ensure that it is centered.

[0043] After pouring and curing, wait until the concrete rapids trough 2 is completely solidified before removing the cover mold 5, the outer mold 4 and the "U"-shaped inner mold 3. First remove the cover mold 5, remove the top cover mold 5, and then remove the remaining cover molds 5 in succession. The specific working principle is that the top trigger plate 20 is pressed to rotate the rotating rod 18, and the rotating rod 18 drives the fork 19 to rotate and press down the sliding block 21. The sliding block 21 slides along the column 22 so that the wire rope 24 pulls the inner hook 16 and the outer hook 15 to rotate, so that the outer hook 15 is disengaged from the outer mold 4, and the inner hook 16 is disengaged from the clamping angle block 11. At the same time, the cover mold 5 is rotated, and the cover mold 5 rotates along the supporting cross bar 10 below. At this time, the trigger rod 14 moves along the limit groove 25. Sliding, during this process, the trigger plate 20 and the rotating rod 18 on the next covering mold 5 rotate, the rotating rod 18 drives the fork 19 to rotate and press down the sliding block 21 on the next covering mold 5, and the sliding block 21 slides along the column 22 so that the wire rope 24 pulls the inner hook 16 and the outer hook 15 to rotate, so that the outer hook 15 is disengaged from the engagement with the outer mold 4, and the inner hook 16 is disengaged from the engagement with the engaging corner block 11, and then the top covering mold 5 can also drive the next covering mold 5 to disengage from the engagement with the outer mold 4 and the "U"-shaped inner mold 3, so all the covering molds 5 can also be quickly removed according to the above-mentioned actions.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Within the technical scope disclosed by the present invention, technicians familiar with the technical field can make equivalent replacements or changes based on the technical scheme and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
