Description
本申请涉及桥梁施工设备领域,特别涉及一种用于水下硬质土层的吸泥机。This application relates to the field of bridge construction equipment, in particular to a suction dredge used for underwater hard soil layers.
一般,在桥梁的深水沉井基础施工中,需要先将沉井基础底部的土层抽吸掉,才能进行沉井取土下沉,或者在进行钢围堰的施工时,常规双壁钢围堰在覆盖层中下沉方式多选择为吸泥下沉,因此,吸泥机在桥梁施工时应用十分普遍。Generally, in the construction of the deep-water caisson foundation of a bridge, the soil at the bottom of the caisson needs to be sucked out before the sinking of the caisson can be carried out, or when the construction of a steel cofferdam is carried out, the conventional double-wall steel enclosure The sinking method of the weir in the overburden is mostly suction sinking. Therefore, the mud suction machine is widely used in bridge construction.
相关技术中,空气吸泥设施由于其具有施工工艺简单、投入较少成本低、取泥速度快等优点被广泛使用,常规的空气吸泥机主要构造由吸泥头、吸泥管、高压风管等组成,其主要原理为利用较大的内外压差将泥沙通过吸泥头吸入。然而,此种吸泥机因对覆盖层扰动较小,吸泥效果相对不佳,影响了吸泥质量和吸泥效率。目前,为了改善吸泥机的吸泥质量和吸泥效率,往往在机头上增加一些辅助结构,例如搅拌棒,其用于在吸泥头吸泥的同时以一定的速度旋转,以搅动吸泥机头四周的淤泥,从而保证更好的吸泥效果,另外也能对机头上吸附的污泥更好的清理。In related technologies, air suction mud facilities are widely used due to their simple construction process, low investment, low cost, and fast mud removal speed. The conventional air suction mud machine is mainly composed of suction head, suction pipe, and high-pressure air. The main principle is to use a large internal and external pressure difference to suck the sediment through the mud suction head. However, this kind of mud suction machine has less disturbance to the overburden, and the mud suction effect is relatively poor, which affects the mud suction quality and mud suction efficiency. At present, in order to improve the mud suction quality and efficiency of the mud suction machine, some auxiliary structures are often added to the machine head, such as a stirring rod, which is used to rotate at a certain speed while the suction head sucks mud to agitate the suction. The sludge around the sludge head can ensure a better suction effect, and it can also better clean up the sludge adsorbed on the head.
但是,目前桥梁施工时,有时会遇到硬质土层,现有的吸泥机通常都是在软质土层的上表面进行工作,在硬质土层的上表面进行作业时,不能够达到较好的吸泥效果;另外,水底经常会有杂物如体积较大的块石等,较易造成吸泥头堵塞,很大程度上影响了吸泥的效果。However, the current bridge construction sometimes encounters hard soil layers. Existing suction dredges usually work on the upper surface of the soft soil layer. When working on the upper surface of the hard soil layer, they cannot Achieve better mud suction effect; in addition, there are often debris at the bottom of the water, such as large stones, etc., which are more likely to cause blockage of the mud suction head, which greatly affects the mud suction effect.

具体的,增压组件包括集风箱12和高压气泵,集风箱12主要包括一集风腔,集风箱12被配置为:吸泥管10穿设于集风箱12上且通过集风腔,位于吸泥管10上的增压孔11均与集风腔连通,高压气泵设于集风箱12的上方,一般位于水平面上,且通过管道与集风箱12的顶部相连并与集风腔连通,高压气泵用于向集风腔内注入高流速的空气以在吸泥管10内形成具有高流速的往上流通的空气流。具体原理 为:当需要吸泥时,启动高压气泵往集风箱12内吹气,高压气体汇集在集风腔内并通过增压孔11,由于增压孔11的方向均朝上倾斜,参见图9所示,因此,高压气泵产生的高压气体最后通过增压孔11进入吸泥管10并朝上流动,以将位于吸泥管10内的泥水混合物排出,排出后后续的水持续进来,从而达到将管外的泥水混合物吸入管内的目的。Specifically, the pressurizing assembly includes a wind box 12 and a high-pressure air pump. The wind box 12 mainly includes a wind collecting cavity. The pressure-increasing holes 11 on the mud pipe 10 are all connected with the air-collecting cavity. The high-pressure air pump is arranged above the air-collecting box 12, generally on a horizontal surface, and is connected to the top of the air-collecting box 12 through a pipe and communicates with the air-collecting cavity. It is used to inject high-velocity air into the air-collecting cavity to form an upwardly circulating air flow in the mud suction pipe 10 with a high-velocity. The specific principle is: when mud suction is needed, start the high-pressure air pump to blow air into the wind box 12, and the high-pressure gas collects in the wind collecting cavity and passes through the booster hole 11, because the direction of the booster hole 11 is inclined upward, see figure Therefore, the high-pressure gas produced by the high-pressure air pump finally enters the mud suction pipe 10 through the pressure-increasing hole 11 and flows upward to discharge the mud-water mixture in the mud suction pipe 10, and subsequent water continues to enter after being discharged, thereby To achieve the purpose of sucking the mud-water mixture outside the pipe into the pipe.
具体的,参见图3-图5所示,碎泥机构主要包括分流管21和高压水泵,从结构设计的角度出发,分流管21设于集风腔内,分流管21呈圆形,其管段上间隔设有至少两个出水口,出水口伸出于集风箱12外,每一出水口均与其中一碎泥组件20相连,高压水泵则设于集风箱12的上方,且通过管道与分流管21的一端相连,碎泥组件20主要包括射水管22和设于射水管22端部的喷嘴23,射水管22与与其对应的出水口连通。具体原理为:在吸泥前,需要先将水底硬质土层击碎,此时启动高压水泵,高压水泵对水加压,高压水并顺着管道、分流管21和射水管22最后通过喷嘴23射出,具有高压的水柱具有较大的冲击力,因此一般情况下均可以将水下的硬质土层击碎。Specifically, as shown in Figures 3 to 5, the mud crushing mechanism mainly includes a shunt pipe 21 and a high-pressure water pump. From the perspective of structural design, the shunt pipe 21 is set in the air-collecting cavity. The shunt pipe 21 is circular, and its pipe section There are at least two water outlets on the upper space. The water outlets extend out of the wind box 12, and each water outlet is connected to one of the mud components 20. The high-pressure water pump is arranged above the wind box 12 and is connected to the flow divider through pipes. One end of the pipe 21 is connected, and the mud-crushing assembly 20 mainly includes a water jetting pipe 22 and a nozzle 23 provided at the end of the water jetting pipe 22, and the water jetting pipe 22 communicates with the corresponding water outlet. The specific principle is: before sucking mud, the hard bottom soil layer needs to be crushed. At this time, the high-pressure water pump is started, and the high-pressure water pump pressurizes the water. The high-pressure water flows along the pipes, the shunt pipe 21 and the water jet pipe 22 and finally passes through the nozzles. 23 shot, the high-pressure water column has a greater impact, so under normal circumstances, it can crush the hard soil under the water.
具体的,射水管22与出水口的连接处设有转动件,转动件连接有驱动电机,驱动电机用于驱动转动件在一定范围内转动以调节射水管22的角度,以保证在击碎土层时能较易击碎周边的土层,增加吸泥效率,保证吸泥的效果。碎泥组件20的个数为4~8个,这里,碎泥组件20的个数优选为4个。Specifically, a rotating part is provided at the connection between the water injection pipe 22 and the water outlet, and the rotating part is connected with a driving motor. The driving motor is used to drive the rotating part to rotate within a certain range to adjust the angle of the water injection pipe 22 to ensure that the soil is crushed. When layering, it is easier to break the surrounding soil layer, increase the efficiency of mud suction, and ensure the effect of mud suction. The number of crushed mud assemblies 20 is 4 to 8, and here, the number of crushed mud assemblies 20 is preferably four.
具体的,参见图7和图8所示,防堵组件3呈筒状,其一端与吸泥管10可拆卸卡接相连,远离吸泥管10的一端则为锯齿状,另外防堵组件3内设有呈井字形的格栅。此防堵组件3的原理为:由于端部为锯齿状,因此当吸附较大的土块时,由于具有一定速度,因此具有锯齿的端部足够将土块击碎,防止其堵塞管道;水底往往还沉有一些石头,有的石头体积较大,而呈井字形的格栅则可以有效的将此类石 头挡住,防止被吸入管道内后造成堵塞而不方便清理。Specifically, referring to Figures 7 and 8, the anti-blocking component 3 is in a cylindrical shape, one end of which is detachably connected to the suction pipe 10, and the end away from the suction pipe 10 is serrated. In addition, the anti-blocking component 3 There is a grid in the shape of a well. The principle of this anti-blocking component 3 is: because the end is sawtooth, when adsorbing larger soil blocks, due to a certain speed, the sawtooth end is enough to break the soil blocks and prevent them from clogging the pipeline; Some stones are often sunk, and some stones are relatively large, and the grid shaped like a tic can effectively block these stones to prevent them from being sucked into the pipe and causing blockage and inconvenient cleaning.
进一步的,防堵组件3包括连接头和至少3个曲形防堵件,连接头呈环形且转动连接于吸泥管10的底部,所有曲形防堵件的一端间隔设于连接头上,且吸泥管10的端部位于所有曲形防堵件的竖直投影面积内,每一个曲形防堵件的两侧上均间隔设有多个防堵头。具体的,此种结构的防堵组件3的防堵原理为:在吸泥时,喷嘴23喷出具有高压的水柱将硬质土层击碎,吸泥管10将泥水混合物吸入管内,此时,连接头在持续转动,从而带动与其连接的曲形防堵件也在转动,这里的曲形防堵件为立体曲形结构,且每一曲形防堵件的宽度朝着远离吸泥管10的方向逐渐变窄,其两侧沿长度方向间隔设有防堵头,多个旋转的曲形防堵件相当于在吸泥管10的底部形成了防堵保护区,当大的土块过来时,旋转的曲形防堵件可以轻易将土块击碎,而当大的石块过来时石块可能被转动的曲形防堵件击走或击碎,能有效的防止这些大的障碍物进入吸泥管10管道内造成堵塞。另外,旋转的曲形防堵件在一定程度上也可以起到击碎硬质土层的作用,辅助碎泥组件20共同作用。Further, the anti-blocking assembly 3 includes a connector and at least three curved anti-blocking parts. The connecting head is in the shape of a ring and is rotatably connected to the bottom of the mud suction pipe 10. Moreover, the end of the mud suction pipe 10 is located in the vertical projection area of all the curved anti-blocking parts, and a plurality of anti-blocking heads are spaced apart on both sides of each curved anti-blocking part. Specifically, the anti-clogging principle of the anti-clogging assembly 3 of this structure is: when mud is sucked, the nozzle 23 sprays a high-pressure water column to break the hard soil layer, and the mud suction pipe 10 sucks the mud-water mixture into the pipe. , The connecting head continues to rotate, thereby driving the curved anti-blocking piece connected to it to also rotate. The curved anti-blocking piece here is a three-dimensional curved structure, and the width of each curved anti-blocking piece faces away from the suction pipe The direction of 10 is gradually narrowed, and anti-blocking heads are arranged at intervals along the length direction on both sides. Multiple rotating curved anti-blocking pieces are equivalent to forming an anti-blocking protection area at the bottom of the suction pipe 10, when large soil blocks When coming over, the rotating curved anti-blocking piece can easily break the soil block, and when the big stone comes over, the stone may be knocked away or broken by the rotating curved anti-blocking piece, which can effectively prevent these large blocks. Obstacles enter into the suction pipe 10 and cause blockage. In addition, the rotating curved anti-blocking member can also play a role in breaking the hard soil layer to a certain extent, and the auxiliary mud assembly 20 works together.
具体的,增压孔11与水平面之间的夹角不小于45°,以保证从增压孔11出来的高压气体能往上走。参见图6所示,吸泥管10的顶部还连接有出泥管13,出泥管13呈L形,且拐角处呈圆弧形,方便泥水混合物的排出。吸泥管10与出泥管13之间采用连接法兰连接,集风箱12与位于其顶部的管道之间也采用连接法兰连接。Specifically, the angle between the pressurizing hole 11 and the horizontal plane is not less than 45° to ensure that the high-pressure gas from the pressurizing hole 11 can go upward. As shown in Fig. 6, the top of the mud suction pipe 10 is also connected with a mud outlet pipe 13, which is L-shaped, and the corners are arc-shaped, which facilitates the discharge of the mud-water mixture. The mud suction pipe 10 and the mud outlet pipe 13 are connected by a connecting flange, and the air collecting box 12 and the pipe on the top thereof are also connected by a connecting flange.
