摘要：【中文】本发明公开一种具有降噪功能的一体式活动吊耳，包括吊耳支座和活动吊耳；所述活动吊耳呈Y型，包括竖部和叉部；所述竖部插入吊耳支座的缺口中，并通过第一吊耳销栓接；上述缺口中设有第一橡胶衬套，所述第一橡胶衬套套设在第一吊耳销上，所述竖部套设在第一橡胶衬套外壁；所述叉部端部之间设有第二橡胶衬套，所述第二橡胶衬套通过第二吊耳销固定在活动吊耳上；所述橡胶衬套外壁设有板簧卷耳。通过橡胶衬套的作用，消除了噪声。活动吊耳和吊耳支座均为铸钢工艺，制造简单易行。该结构不用加黄油，实现免维护，且多个零部件结构相同，互换性较强，降低了成本，提升了产品的品质，值得推广。 【EN】The invention discloses an integrated movable lifting lug with a noise reduction function, which comprises a lifting lug support and a movable lifting lug; the movable lifting lug is Y-shaped and comprises a vertical part and a fork part; the vertical part is inserted into the notch of the lifting lug support and is bolted through a first lifting lug pin; a first rubber bushing is arranged in the notch, the first rubber bushing is sleeved on the first lifting lug pin, and the vertical part is sleeved on the outer wall of the first rubber bushing; a second rubber bushing is arranged between the end parts of the fork parts and is fixed on the movable lifting lug through a second lifting lug pin; and the outer wall of the rubber bushing is provided with a plate spring eye. Noise is eliminated by the action of the rubber bushing. The movable lifting lug and the lifting lug support are both cast steel processes, and the manufacturing is simple and easy. The structure does not need to add butter, realizes maintenance-free, has the same structure of a plurality of parts, has stronger interchangeability, reduces the cost, promotes the quality of products, and is worth popularizing.

摘要：【中文】本发明公开了一种置于暗挖车站上方底部侧墙四通的施工竖井及施工方法，包括以下步骤，步骤一、施工锁口圈梁及井口围墙；步骤二、开挖施工竖井基坑，架设竖井格栅钢架并喷射混凝土浇筑制成井护壁；步骤三、将锁口圈梁与框架柱钢筋笼连接；步骤四、将锁口圈梁钢筋笼与框架柱钢筋笼混凝土浇筑为一体；步骤五、施工框架柱；步骤六、利用钢板连接节点将框架梁钢筋笼与竖井格栅钢架焊接为一体；步骤七、施作竖井内底板；步骤八、开挖施工水平横通道；步骤九、在施工横通道内采用小导洞开挖及洞内梁柱结构体系施工；步骤十、基于步骤八，破除施工竖井内剩余相对的双方向侧墙，进行初支扣拱施工。本发明结构稳定，并可有效控制地面沉降。 【EN】The invention discloses a construction vertical shaft of a bottom side wall four-way joint arranged above a subsurface excavated station and a construction method, wherein the construction vertical shaft comprises the following steps of constructing a locking collar beam and a well mouth enclosing wall; secondly, excavating a construction shaft foundation pit, erecting a shaft grid steel frame and spraying concrete to cast the shaft grid steel frame to form a shaft retaining wall; step three, connecting the locking collar beam with the frame column reinforcement cage; step four, pouring the locking collar beam reinforcement cage and the frame column reinforcement cage into a whole; constructing a frame column; step six, welding the frame beam reinforcement cage and the vertical shaft grating steel frame into a whole by utilizing the steel plate connecting nodes; constructing a bottom plate in the vertical shaft; step eight, excavating a horizontal construction channel; step nine, adopting small pilot tunnel excavation and in-tunnel beam column structure system construction in the construction transverse channel; and step ten, based on the step eight, breaking the residual opposite bidirectional side walls in the construction shaft, and performing primary support buckling arch construction. The invention has stable structure and can effectively control the ground settlement.
