技术领域Technical Field
本发明属于盾构隧道回填领域，具体涉及一种小盾构隧道回填装置。The invention belongs to the field of shield tunnel backfilling, and in particular relates to a small shield tunnel backfilling device.
背景技术Background technique
大盾构扩挖小盾构施工的施工方法是我国首创的地铁施工方式，意思是用直径8.8米大盾构推直径6.7米小盾构管片扩挖地铁车站的盾构施工工法。小盾构隧道回填采取分层分段的方式进行，回填材料选用流动性较好的混凝土，回填分3层进行，第一层回填至隧底以上1.5m处，第二层回填至隧底以上4m处，第三层回填至隧底顶部。一层回填不分段一次浇筑到位，第二、三层回填采取分段形式进行。The construction method of expanding the small shield by the large shield is the first subway construction method in my country. It means using a large shield with a diameter of 8.8 meters to push a small shield with a diameter of 6.7 meters to expand the subway station. The backfill of the small shield tunnel is carried out in layers and sections. The backfill material is concrete with good fluidity. The backfill is carried out in three layers. The first layer is backfilled to 1.5m above the tunnel bottom, the second layer is backfilled to 4m above the tunnel bottom, and the third layer is backfilled to the top of the tunnel bottom. The first layer of backfill is poured in one go without being divided into sections, and the second and third layers of backfill are carried out in sections.
当对隧道进行分层填充时，对底层填充并凝固后，当开始对底层的上一层进行回填时，由于底层已经凝固，使两层混凝土出现分层现象，使两层混凝土之间的吸附力较小，导致两层混凝土出现分层现象，会影响两层回填混凝土之间的嵌合。When the tunnel is filled in layers, after the bottom layer is filled and solidified, when the backfilling of the upper layer of the bottom layer begins, the two layers of concrete will be layered because the bottom layer has already solidified, making the adsorption force between the two layers of concrete smaller, resulting in the two layers of concrete being layered, which will affect the fit between the two layers of backfill concrete.

本发明的技术效果和优点：本发明提出的一种小盾构隧道回填装置，与现有技术相比，具有以下优点：Technical effects and advantages of the present invention: Compared with the prior art, the small shield tunnel backfilling device proposed by the present invention has the following advantages:
1、本发明通过弧形刮板，滚轮在弧形块表面滑过，在第一弹簧的作用下，使第二竖杆带动第一竖杆在吊杆的下端上下运动，带动弧形刮板上下运动，当弧形刮板随吊杆前进时，弧形刮板上下刮动底层混凝土的表面，使填充的混凝土上表面形成波浪，同时由于弧形刮板的下端为弧形，使填充混凝土的截面为弧形，当对隧道上层进行填充时，底层波浪形表面有助于相邻两层混凝土之间的贴合，使两层混凝土之间嵌合的更加稳固。1. The present invention uses an arc-shaped scraper, and the roller slides on the surface of the arc-shaped block. Under the action of the first spring, the second vertical rod drives the first vertical rod to move up and down at the lower end of the suspension rod, driving the arc-shaped scraper to move up and down. When the arc-shaped scraper moves forward with the suspension rod, the arc-shaped scraper scrapes the surface of the bottom concrete up and down, so that the upper surface of the filled concrete forms waves. At the same time, since the lower end of the arc-shaped scraper is arc-shaped, the cross-section of the filled concrete is arc-shaped. When the upper layer of the tunnel is filled, the wavy surface of the bottom layer helps to fit between the two adjacent layers of concrete, making the embedding between the two layers of concrete more stable.
2、本发明通过设置平直刮板，当第二竖杆上下运动时，带动齿条上下运动，带动两侧的齿轮转动，齿轮带动拨动杆向两侧转动，拨动杆带动弧形滑块在弧形通槽内向上滑动，平直刮板随弧形滑块向上运动，运动过程中平直刮板刮起部分混凝土，将部分混凝土抹到隧道墙壁上，使底层混凝土在隧道侧壁上每隔一段距离出现一块高于底层混凝土的混凝土块，如此当对上层进行填充时，混凝土块伸入上层混凝土层，当上层混凝土层凝固时，使两层混凝土层之间嵌合的更加紧密。2. The present invention arranges a straight scraper. When the second vertical rod moves up and down, it drives the rack to move up and down, drives the gears on both sides to rotate, the gears drive the toggle rod to rotate to both sides, the toggle rod drives the arc-shaped slider to slide upward in the arc-shaped through groove, and the straight scraper moves upward with the arc-shaped slider. During the movement, the straight scraper scrapes up part of the concrete and smears part of the concrete on the tunnel wall, so that a concrete block higher than the bottom concrete appears on the tunnel side wall at a certain distance. In this way, when the upper layer is filled, the concrete block extends into the upper concrete layer. When the upper concrete layer solidifies, the two concrete layers are more tightly fitted.
3、本发明通过设置竖直刮板，弧形板的第一斜面将限位板向上托起，第三弹簧处于压缩蓄力状态，当弧形滑块在弧形通槽内向上滑动时，弧形板与限位板脱离接触，第三弹簧将竖直刮板向下推动，使竖直刮板向下滑动并从安装槽内突出，当弧形刮板在底层混凝土表面进行刮动时，竖直刮板刮动底层混凝土，使底层表面出现更深的沟槽，当弧形滑块在弧形通槽内向下滑动时，弧形板上的第一斜面将限位板托起，使竖直刮板向上滑动并进入安装槽内，当对上层混凝土进行浇筑时，上层混凝土灌入沟槽，当上层混凝土凝固时，使两层混凝土之间更加紧密，增大两层混凝土之间的嵌合力。3. The present invention sets a vertical scraper, and the first inclined surface of the arc plate lifts the limit plate upward. The third spring is in a compressed and force-storing state. When the arc-shaped slider slides upward in the arc-shaped through groove, the arc plate is out of contact with the limit plate, and the third spring pushes the vertical scraper downward, causing the vertical scraper to slide downward and protrude from the mounting groove. When the arc-shaped scraper scrapes the surface of the bottom concrete, the vertical scraper scrapes the bottom concrete, causing deeper grooves to appear on the bottom surface. When the arc-shaped slider slides downward in the arc-shaped through groove, the first inclined surface on the arc plate lifts the limit plate, causing the vertical scraper to slide upward and enter the mounting groove. When the upper concrete is poured, the upper concrete is poured into the groove. When the upper concrete solidifies, the two layers of concrete are made closer, thereby increasing the fitting force between the two layers of concrete.

When the upper layer of concrete is poured, the upper layer of concrete is poured into the groove 400. When the upper layer of concrete solidifies, the two layers of concrete are made closer, thereby increasing the fitting force between the two layers of concrete.
使用时，滑动车11在滑轨1上滑动，推动吊杆14在滑轨1上滑动，滑动过程中，灌浆车100将填充混凝土通过运输管13输送进隧道，滑动过程中，第二竖杆17上端的滚轮23在弧形块18表面滑过，使第二竖杆17带动第一竖杆15在吊杆14的下端上下运动，带动弧形刮板19上下刮动底层混凝土的表面，使填充的混凝土上表面形成波浪，当第二竖杆17上下运动时，带动齿条29上下运动，当齿条29向下运动时带动两侧的齿轮27转动，齿轮27带动拨动杆3向两侧转动，拨动杆3带动弧形滑块31在弧形通槽内向上滑动，平直刮板32随弧形滑块31向上运动，运动过程中平直刮板32刮起部分混凝土，将部分混凝土抹到隧道墙壁上，使底层混凝土在隧道侧壁上每隔一段距离出现一块高于底层混凝土的混凝土块300，当弧形滑块31在弧形通槽内向上滑动时，弧形板27与限位板24脱离接触，第三弹簧35将竖直刮板36向下推动，使竖直刮板36向下滑动并从安装槽内突出，当弧形刮板19在底层混凝土表面进行刮动时，竖直刮板36刮动底层混凝土，使底层表面出现更深的沟槽400。When in use, the sliding vehicle 11 slides on the slide rail 1, pushing the suspension rod 14 to slide on the slide rail 1. During the sliding process, the grouting vehicle 100 transports the filled concrete into the tunnel through the transport pipe 13. During the sliding process, the roller 23 at the upper end of the second vertical rod 17 slides over the surface of the arc block 18, so that the second vertical rod 17 drives the first vertical rod 15 to move up and down at the lower end of the suspension rod 14, driving the arc scraper 19 to scrape the surface of the bottom concrete up and down, so that waves are formed on the upper surface of the filled concrete. When the second vertical rod 17 moves up and down, it drives the rack 29 to move up and down. When the rack 29 moves downward, it drives the gears 27 on both sides to rotate. The gear 27 drives the toggle rod 3 to rotate to both sides, and the toggle rod 3 drives the arc slide The block 31 slides upward in the arc groove, and the straight scraper 32 moves upward with the arc slider 31. During the movement, the straight scraper 32 scrapes up part of the concrete and smears part of the concrete on the tunnel wall, so that a concrete block 300 higher than the bottom concrete appears on the tunnel side wall at a certain distance. When the arc slider 31 slides upward in the arc groove, the arc plate 27 is out of contact with the limit plate 24, and the third spring 35 pushes the vertical scraper 36 downward, so that the vertical scraper 36 slides downward and protrudes from the installation groove. When the arc scraper 19 scrapes the surface of the bottom concrete, the vertical scraper 36 scrapes the bottom concrete, so that deeper grooves 400 appear on the bottom surface.
