Example 1
Referring to fig. 1, the present embodiment provides a dust-proof structure for a foundation pit support 51 in guniting construction, including:
the track structure comprises a movable track 10 which is arranged at the top of the edge of the foundation pit 50 and surrounds the edge of the foundation pit 50;
a moving structure including a plurality of moving seats 21 movable along the extending direction of the moving rail 10, the plurality of moving seats 21 being sequentially arranged along the moving rail 10;
dustproof construction, dustproof construction includes dustproof curtain 32 and the corresponding arm 31 of encorbelmenting of removal seat 21 quantity, the arm 31 of encorbelmenting is corresponding to be installed on corresponding removal seat 21 and extend to within foundation ditch 50, dustproof curtain 32 is located the below of arm 31 of encorbelmenting, the top of dustproof curtain 32 is connected on each arm 31 of encorbelmenting extends to the end within foundation ditch 50, dustproof curtain 32 hangs to 51 lateral part of excavation supporting to cover part excavation supporting 51 lateral part, leave a determining deviation between dustproof curtain 32 and the excavation supporting 51 lateral part, in order to form the whitewashing space that is used for placing the patching machine.
Referring to fig. 2, it can be known that: in this embodiment, the entire cantilever arm 31 extends horizontally into the pit 50, and the dust curtain 32 is connected to the end of the cantilever arm 31, so that the dust curtain 32 is located outside the side wall of the pit support 51 and spaced from the side wall of the pit support 51. Meanwhile, since the moving rail 10 is attached to the edge of the entire excavation 50, each of the moving base 21 and the dust curtain 32 can be moved to a proper position (i.e., the outside of the side portion of the excavation support 51 to be subjected to the shotcreting process) for covering.
This embodiment is mainly through setting up dustproof curtain 32 for excavation supporting 51 is when carrying out the whitewashing and handling, and the sprayed concrete that splashes out and raise dust can receive dustproof curtain 32's hindrance effect, thereby reduces excavation supporting 51 whitewashing construction and to the environmental impact that the construction phenomenon caused. More importantly, the dust-proof curtain 32 is installed on the moving rail 10 surrounding the whole foundation pit 50, so that the operator can realize the dust-proof operation on the whole foundation pit 50 only by arranging the dust-proof curtain 32 with a small area, and the structure has the remarkable advantages of low implementation cost and high implementation efficiency.
The specific use method of the dustproof structure comprises the following steps:
s1, placing the shotcrete machine outside the side part of the foundation pit support 51 to be subjected to shotcrete treatment;
s2, moving each moving seat 21 along the moving track 10 to make the dustproof curtain 32 be positioned at the outer side of the guniting machine and cover the side part of the foundation pit support 51 to be guniting treated;
s3, starting a guniting machine to carry out guniting;
and S4, after the guniting is finished, repeating the steps S1 to S3 until the guniting of the whole foundation pit support 51 is finished.
In addition, the height range of the guniting operation surface supported by the deep foundation pit 50 is large, and higher requirements are made on the height of the dustproof curtain 32 in the vertical direction. In the preferred embodiment, the cantilever arm 31 and the dust curtain 32 are connected by a longitudinal adjusting structure.
The vertical adjusting structure can correspondingly adjust the height of the dustproof curtain 32, so that the dustproof curtain 32 can be vertically adjusted to the most appropriate position, and the requirement on the height of the dustproof curtain 32 in the vertical direction is reduced.
More specifically, in this embodiment, the longitudinal adjustment structure includes a threaded rod 41 arranged in a vertical direction, the threaded rod 41 penetrates into the middle of the end of the cantilever arm 31 and is in threaded connection with the cantilever arm 31, and the bottom end of the threaded rod 41 is connected with the top of the dust curtain 32 through a chain 42. The practitioner can adjust the vertical interval between the bottom end of the threaded rod 41 and the cantilever arm 31 by screwing in or screwing out the whole threaded rod 41, and then the effect of adjusting the height of the dustproof curtain 32 is achieved.
Meanwhile, for the dust curtain 32, it is desirable to be disposed between the dust curtain and the cantilever 31 so as to be able to be detached quickly for replacement. Therefore, in this embodiment, the top of the dust curtain 32 is provided with a hooking hole, and the bottom of the chain 42 is provided with a connecting hook 43 for hooking with the hooking hole of the dust curtain 32. After adjusting the threaded rod 41 to a proper position, the operator can connect the dust curtain 32 through the connecting hook 43.
In addition, in the process of guniting construction, most of the generated dust is easy to fly, so that the dustproof curtain 32 is only arranged outside the side part of the foundation pit support 51, and the dustproof effect is limited. In the preferred embodiment, the horizontally arranged dust-proof plates 33 are fixedly mounted on the portions of the cantilever arms 31 extending to the inside of the foundation pit 50, and each dust-proof plate 33 partially covers the top of the guniting space. The dust guard 33 can seal the top in whitewashing space, and then promotes whole dustproof construction's dustproof effect.
Referring to fig. 2, since the edge of the foundation pit 50 is mostly in an irregular polygon shape, a right-angle area exists often, and if the dust-proof plates 33 are set to have a uniform height, two adjacent dust-proof plates 33 may collide with each other in the right-angle area, so that the moving seat 21 cannot move to a proper position, as a preferred embodiment, in this embodiment, the dust-proof plates 33 installed on two adjacent cantilever arms 31 are vertically staggered from each other.
Referring to fig. 3, as a preferred embodiment, in the present embodiment, the moving rail 10 includes a rail groove 11 slidably engaged with the moving base 21, a plurality of first connection holes extending in the vertical direction are formed at the bottom of the rail groove 11, a second connection hole extending in the vertical direction and penetrating through the moving base 21 is formed on the moving base 21, and the moving base 21 can selectively align the second connection hole with any one of the first connection holes by sliding in the rail groove 11, so that the limiting bolt 22 can simultaneously penetrate through the first connection hole and the second connection hole, thereby limiting the sliding of the moving base 21 along the rail groove 11, realizing the locking of the moving base 21 and the dust-proof curtain 32, and ensuring the stability of the dust-proof curtain 32 during the slurry spraying construction process.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
