在具体使用时，根据本实用新型所述的自密实混凝土灌注门式扣压装置，首先在混凝土底座板的中间位置或精调爪安装位置9附近钻孔并用气筒吹出杂物，钻孔直径为φ20mm、深度为10cm，随后植入膨胀螺栓6，螺栓外漏不宜过长，一般在5～10cm左右，并且需要达到17KN的抗拔力；接着将所述扣压装置放置在轨道板上，用紧线器5连接所述膨胀螺栓6，精调完成后拉紧紧线器5将轨道板紧固，防止轨道板产生上浮；接着，将封边模具4安装在轨道板的两侧，并通过扣压螺栓7连接钢架支腿2并紧固封边模具4，防止轨道板发生侧向位移，还可以在扣压时在附近安装百分表进行观测;固定完毕将原浆通过灌浆孔8灌入，静置一段时间，当自密实砼膨胀已经完成后，一般应控制在模板拆除2小时候（此时间根据温度变化适当延长）方可拆除扣压装置，抽出侧向钢筋，而侧向封边模具4应该在自密实砼混凝土的强度达到30%（12Mpa）后方可拆除，模板拆除后，用原浆将固定扣压装置的螺栓孔进行补孔，先采用毛刷清理、润湿处理，灌注原浆，灌注完成后进行压光、抹平；一般在直线地段单侧设置4个扣压装置，曲线地段设置5个扣压装置。 In specific use, according to the self-compacting concrete pouring gantry crimping device described in the utility model, firstly drill a hole near the middle position of the concrete base plate or the installation position 9 of the fine adjustment claw and blow out debris with an air cylinder, and the diameter of the drill hole is φ20mm , the depth is 10cm, and then the expansion bolt 6 is implanted. The leakage of the bolt should not be too long, generally about 5-10cm, and the pull-out force of 17KN is required; The expansion bolt 6 is connected to the expansion bolt 6 by the device 5. After the fine adjustment is completed, the tensioner 5 is tightened to fasten the track plate to prevent the track plate from floating; then, install the edge banding mold 4 on both sides of the track plate, and press the bolt 7. Connect the steel frame legs 2 and fasten the edge-sealing mold 4 to prevent the lateral displacement of the track plate. You can also install a dial indicator nearby for observation during crimping; after fixing, pour the original slurry through the grouting hole 8, After the expansion of the self-compacting concrete has been completed, it should be controlled for 2 hours after the formwork is removed (this time should be appropriately extended according to the temperature change) before the withholding device can be removed and the lateral steel bars can be pulled out, and the lateral edge sealing mold 4 should be in the The self-compacting concrete can be dismantled after the strength of the concrete reaches 30% (12Mpa). After the formwork is dismantled, use the original slurry to fill the bolt holes of the fixed withholding device. First, use a brush to clean and wet it, and pour the original slurry, and the injection is completed. Afterwards, calendering and smoothing are carried out; generally, 4 withholding devices are installed on one side of the straight section, and 5 withholding devices are installed on the curved section.
当在超高地段施工时应增设防侧滑装置，通过超高内侧底座板顶部锚固防侧滑钢筋13配合防侧滑槽钢11和横向可调节的防侧滑螺栓12来加强限制侧向位移，防侧滑钢筋采用φ25螺纹钢筋，锚固长度不小于15cm。 When constructing in ultra-high areas, an anti-sideslip device should be added, and the anti-sideslip steel bar 13 is anchored on the top of the super-high inner base plate, combined with the anti-sideslip channel steel 11 and the horizontally adjustable anti-slip bolt 12 to strengthen and limit the lateral displacement. , The anti-skid reinforcement adopts φ25 threaded reinforcement, and the anchorage length is not less than 15cm.
