Description

Technical Field

[0001] The utility model relates to the technical field of curtain grouting construction auxiliary tooling, in particular to a reservoir hazard removal and reinforcement auxiliary device. Background Art

[0002] In order to reduce the seepage volume and seepage pressure of the reservoir dam and ensure the seepage stability of the foundation, curtain grouting construction is usually required. Part of the curtain grouting construction process is carried out in deep water. During construction, a row or more curtain grouting holes are first drilled on the toe plate, and then an orifice pipe is buried at the orifice position of the borehole, and finally the grouting is completed through the orifice pipe. In the prior art, in order to reduce the influence of factors such as water flow on the underwater part of the orifice pipe and improve the stability during the grouting process, a sweeping rod and a transverse fixing rod are connected to the orifice pipe. The sweeping rod is located near the connection between the orifice pipe and the toe plate, and the transverse fixing rod is located above the sweeping rod. The sweeping rod and the transverse fixing rod are used to fix all the orifice pipes together, thereby reducing the risk of deformation and bending of the orifice pipe and effectively improving the grouting quality.

[0003] Although the orifice pipe can be assisted in fixing by the sweeping rod and the transverse fixing rod in the prior art, in the actual fixing process, since the transverse fixing rod is arranged horizontally and the sweeping rod is arranged in a direction parallel to the toe plate, different fixing tools need to be arranged to fix the sweeping rod and the transverse fixing rod respectively, so that the fixing tools used to fix the sweeping rod and the transverse fixing rod need to be installed and fixed separately, making the installation and fixing operation complicated and prone to errors, affecting the fixing efficiency of the sweeping rod and the transverse fixing rod; in addition, the slope of the toe plates in different reservoirs is different, and all the orifice pipes are arranged vertically. Therefore, for toe plates with different slopes, the angle between the sweeping rod and the orifice pipe after fixed connection is different, so a specific fixing tool for fixing the sweeping rod needs to be set each time according to the specific slope of the toe plate, resulting in poor versatility of the fixing tool and increased cost of auxiliary fixation of the orifice pipe. Utility Model Content

[0004] The utility model aims to provide a reservoir hazard removal and reinforcement auxiliary device to solve the problems in the prior art of poor versatility and high tooling cost of fixing sweeping rods during curtain grouting construction of toe boards with different slopes.

[0005] In order to solve the above problems, the utility model adopts the following technical solution: a reservoir hazard removal and reinforcement auxiliary device, including a toe plate and a plurality of orifice tubes arranged at intervals along the toe plate, the orifice tubes are connected with a sweeping rod, the sweeping rod is arranged parallel to the toe plate, and the intersection position of the sweeping rod and each orifice tube is connected with a fixing unit, the fixing unit includes a fixed part and a movable part, the fixed part is detachably connected to the orifice tube, and the movable part is detachably connected to the sweeping rod; a rotating part is fixedly connected to the fixed part, and the movable part is rotatably connected to the rotating part.

[0006] The principle and beneficial effects of this solution are: in this application, the sweeping rod is set at a position close to the toe plate on the orifice tube, and the sweeping rod is set parallel to the toe plate, and then the sweeping rod is fixed at the cross-connection with each orifice tube using a fixing unit, so that all the orifice tubes are connected together by the sweeping rod near the toe plate, thereby improving the structural stability of all the orifice tubes, so that subsequent grouting can be completed more stably and with high quality.

[0007] In the present application, the fixing unit includes a fixed part and a movable part. When fixing the sweeping rod, the fixed part is fixedly connected to the orifice tube, and the movable part is fixedly connected to the sweeping rod, so that the orifice tube and the sweeping rod are installed and fixed by using the fixing unit; at the same time, since a rotating part is fixedly connected to the fixed part in the present application, the movable part and the rotating part are rotatably connected, so in the actual fixing process, the angle of the movable part relative to the fixed part can be adjusted according to the slope of the toe board, so that the movable part in the present application can be used to fix the sweeping rod in toe boards with different slopes. It has strong versatility and can effectively reduce the equipment cost of the sweeping rod fixing tooling.

[0008] Preferably, as an improvement, the orifice tube is also connected to a transverse fixing rod arranged horizontally, the diameter of the transverse fixing rod is equal to the diameter of the sweeping rod, the intersection of the transverse fixing rod and each orifice tube is also connected to the fixing unit, and a positioning part is detachably connected between the fixed part and the movable part in the fixing unit.

[0009] In this solution, by setting the diameter of the transverse fixing rod to be equal to the diameter of the sweeping rod and using a fixing unit to fix the transverse fixing rod, that is, a fixing unit of one structure can be used to fix the sweeping rod or the transverse fixing rod, thereby reducing the types of tooling for auxiliary fixation of the orifice tube, facilitating unified management of fixed tooling, and there is no need to distinguish between tooling of different structures during the installation and fixing process, thereby effectively improving the fixing efficiency of the auxiliary device.

[0010] In addition, the transverse fixing rod is set horizontally, and the orifice tube is set vertically, and the two are always in a mutually perpendicular state. Therefore, when setting the fixing unit in this solution, the structure of the fixing unit is further optimized, that is, a detachable positioning member is set between the fixed part and the movable part in the fixing unit. Since the fixed part and the movable part are already connected by the rotating part, when the fixing unit is used to connect the transverse fixing rod and the orifice tube, the positioning member is used to connect the fixed part and the movable part, so that the fixed part and the movable part cannot rotate relative to each other. At this time, the entire fixing unit can be considered as a whole to fix the transverse fixing rod and the orifice tube, thereby achieving a stable fixation of the transverse fixing rod and the orifice tube. When the fixing unit is used to fix the sweeping rod and the orifice tube, the positioning member is eliminated, and the fixed part and the movable part can rotate relative to each other to meet the application scenarios of toe boards with different slopes. Therefore, the fixing unit in this solution can be set differently according to whether the fixed object is the transverse fixing rod or the sweeping rod, thereby better playing an auxiliary fixing role for the orifice tube.

[0011] Preferably, as an improvement, the fixing part includes a fixed C-shaped seat and two fixed locking plates arranged opposite to each other and connected to the C-shaped notch of the fixed C-shaped seat, and a fixed locking screw is detachably connected between the two fixed locking plates; the movable part includes a movable C-shaped seat and two movable locking plates arranged opposite to each other and connected to the C-shaped notch of the movable C-shaped seat, and a movable locking screw is detachably connected between the two movable locking plates.

[0012] In this solution, when using the C-shaped structure to fix the horizontal fixing rod, sweeping rod or orifice tube, it is only necessary to insert the fixing object into the corresponding C-shaped structure through the C-shaped notch, and then use the corresponding locking screw to fix the opposite fixed lock plate or movable lock plate, so as to stably and conveniently fix the horizontal fixing rod, sweeping rod or orifice tube. The structure is simple and the fixing process is easy to operate.

[0013] Preferably, as an improvement, the rotating portion includes a pin fixedly connected to the fixed member, and the movable member is provided with a rotating hole rotatably engaged with the pin.

[0014] In this solution, a pin shaft is used as the rotating part, which has a simple structure and can easily and stably form a rotational cooperation relationship with the movable part, thereby accurately fixing the sweeping rod on toe boards with different slopes.

[0015] Preferably, as an improvement, the positioning member includes a fixing screw, the movable member is provided with a through hole that cooperates with the fixing screw, and the fixing member is provided with a threaded hole that is threadedly fixed to the fixing screw.

[0016] In this solution, the threaded section of the fixing screw is passed through the through hole on the movable part and is threadedly fixed to the threaded hole on the fixed part. Combined with the rotating part structure, the fixed part and the movable part can be placed in a fixed and non-rotatable state. At this time, the orifice tube and the transverse fixed tube can be stably fixed using the fixing unit.

[0017] Preferably, as an improvement, a fixed seat is fixedly connected to the fixed C-shaped seat, a movable seat cooperating with the fixed seat is fixedly connected to the movable C-shaped seat, the through hole is opened on the movable seat, and the threaded hole is opened on the fixed seat.

[0018] In this solution, by setting a fixed seat and a movable seat that cooperate with each other, when the fixed C-type seat and the movable C-type seat cooperate with each other to fix the corresponding components, the set through holes and threaded holes will not affect the structure of the fixed C-type seat and the movable C-type seat, thereby ensuring the stability of the C-type structure, so that the corresponding components can be fixed more firmly, improving the auxiliary fixing effect of the orifice pipe.

[0019] Preferably, as an improvement, the diameter of the pin is greater than or equal to the nominal diameter of the fixing screw, and the diameter of the pin is 1 to 3 times the nominal diameter of the fixing screw.

[0020] Since the movable seat and the fixed seat are only connected by a rotational pin when the sweeping rod is fixed, the fixing screws will be connected between the movable seat and the fixed seat only when the transverse fixing rod and the orifice tube are fixed. Therefore, in order to ensure the connection strength between the fixed C-type seat and the movable C-type seat in this solution, the diameter of the pin is set to be greater than or equal to the nominal diameter of the fixing screw to ensure that under any circumstances, the fixed C-type seat and the movable C-type seat can at least be connected by a pin with a larger diameter, thereby ensuring the stability of the connection structure and thus ensuring the stability of the auxiliary fixation of the orifice tube.

[0021] Preferably, as an improvement, the number of fixed locking screws in each fixed part is one or more, and the number of movable locking screws in each movable part is one or more.

[0022] In this solution, the number of fixed locking screws and movable locking screws is determined according to the actual required fixing strength, with priority given to ensuring the stability of the fixing.

[0023] Preferably, as an improvement, the distance between the sweeping rod and the toe plate is less than or equal to 200 mm.

[0024] In this solution, the sweeping rod is set to a distance of less than or equal to 200 mm from the toe plate, so that the sweeping rod can play a good auxiliary fixing role in the connection position between the bottom of the orifice pipe and the toe plate, ensuring the stability of the overall structure.

[0025] Preferably, as an improvement, the distance between upper and lower adjacent transverse fixing rods is 5 to 8 meters.

[0026] In this solution, the vertical spacing of the transverse fixing rods is set according to the water depth, and the spacing between the upper and lower adjacent transverse fixing rods is set to 5 to 8 meters, taking into account the effect of auxiliary fixation of the orifice pipe and the cost of auxiliary fixation.

[0031] The following is further described in detail through specific implementation methods:

[0032] The figure marks in the drawings of the specification include: toe plate 1, orifice tube 2, sweeping rod 3, transverse fixing rod 4, fixed C-shaped seat 5, fixed seat 501, fixed locking plate 6, fixed locking screw 7, movable C-shaped seat 8, movable seat 801, movable locking plate 9, movable locking screw 10, pin shaft 11, and fixing screw 12.

[0033] Example 1

[0034] This embodiment is as shown in the attached Figure 1 As shown: A reservoir hazard removal and reinforcement auxiliary device includes a toe plate 1 and a plurality of orifice tubes 2 arranged in rows and at intervals along the toe plate 1. All orifice tubes 2 are arranged vertically. A sweeping rod 3 is connected to the orifice tube 2. The sweeping rod 3 is arranged parallel to the toe plate 1 and crosses all orifice tubes 2. The distance between the sweeping rod 3 and the toe plate 1 is less than or equal to 200 mm, and preferably 150 mm in this embodiment. In addition, a plurality of transverse fixing rods 4 are arranged above the sweeping rod 3 and at intervals in the vertical direction. The diameter of the transverse fixing rods 4 is equal to the diameter of the sweeping rods 3, and all transverse fixing rods 4 are arranged horizontally. The spacing between upper and lower adjacent transverse fixing rods 4 is 5 to 8 meters, and preferably 7 meters in this embodiment.

[0035] Combine Figure 1 and Figure 2The cross-connection position between the sweeping rod 3 and the orifice pipe 2 and the cross-connection position between the transverse fixing rod 4 and the orifice pipe 2 are connected with a fixing unit. The fixing unit is used to connect each transverse fixing rod 4 to the orifice pipe 2, and the sweeping rod 3 is connected to all orifice pipes 2. The sweeping rod 3 and all transverse fixing rods 4 are used to connect all orifice pipes 2 as a whole, thereby effectively improving the structural strength and stability of the orifice pipes 2 after connection, and providing a guarantee for subsequent stable grouting.

[0036] In this embodiment, the fixing unit includes a fixing member and a movable member, and a positioning member is detachably connected between the fixing member and the movable member in the fixing unit. The fixing member is detachably connected to the orifice tube 2, and the movable member is detachably connected to the sweeping rod 3 or the transverse fixing rod 4 (i.e., when the orifice tube 2 and the sweeping rod 3 are fixed by the fixing unit, the movable member is detachably connected to the sweeping rod 3, and when the orifice tube 2 and the transverse fixing rod 4 are fixed by the fixing unit, the movable member is detachably connected to the transverse fixing rod 4). Specifically, the fixing part includes a fixed C-shaped seat 5 and two fixed locking plates 6 connected to the C-shaped notch of the fixed C-shaped seat 5, and a fixed locking screw 7 is detachably connected between the two fixing locking plates 6; the movable part includes a movable C-shaped seat 8 and two movable locking plates 9 connected to the C-shaped notch of the movable C-shaped seat 8, and a movable locking screw 10 is detachably connected between the two movable locking plates 9. For example, when the orifice tube 2 is fixed, it is only necessary to push the orifice tube 2 into the fixed C-shaped seat 5 through the C-shaped notch of the fixed C-shaped seat 5, and then use the fixed locking screw 7 to lock with the screw in the prior art to reduce the distance between the two fixed locking plates 6, and finally make the fixed C-shaped seat 5 clamp the orifice tube 2. In addition, in order to improve the fixing effect of the fixing part and the movable part, in this embodiment, the number of fixed locking screws 7 on each fixed C-shaped seat 5 is one or more, and the number of movable locking screws 10 on each movable C-shaped seat 8 is one or more, for example Figure 3 There are two fixed locking screws 7 and two movable locking screws 10 in each fixing unit, and the other numbers are not listed one by one.

[0037] The fixed member is fixedly connected to a rotating portion, and the movable member is rotatably connected to the rotating portion. Specifically, the rotating portion includes a pin 11 welded or threadedly fixed to the fixed C-shaped seat 5, and the movable C-shaped seat 8 is provided with a rotation hole that rotatably cooperates with the pin 11. At the same time, in order to stably and conveniently connect the pin 11 and provide the rotation hole, in this embodiment, a fixed seat 501 is integrally formed on the fixed C-shaped seat 5, and a movable seat 801 is integrally formed on the movable C-shaped seat 8 for use with the fixed seat 501. The pin 11 is fixedly connected to the fixed seat 501, and the rotation hole is provided on the movable seat 801.

[0038] Combine Figure 1 and Figure 2The positioning member includes a fixing screw 12, a through hole for cooperating with the fixing screw 12 is formed on the movable seat 801, and a threaded hole for threadedly fixing with the fixing screw 12 is formed on the fixed seat 501. The nominal diameter of the fixing screw 12 is equal to the diameter of the pin 11. When in use, the fixing screw 12 can be threadedly fixed to the fixed seat 501. Since the pin 11 is already provided between the fixed C-shaped seat 5 and the movable C-shaped seat 8 for rotational connection, after the fixing screw 12 is connected, there are two connection positions between the fixed C-shaped seat 5 and the movable C-shaped seat 8 and they cannot rotate relative to each other. A fixed connection relationship is formed between the fixed C-shaped seat 5 and the movable C-shaped seat 8. At this time, the fixed C-shaped seat 5 and the movable C-shaped seat 8 are fixed to the orifice tube 2 and the transverse fixing rod 4 respectively, so that the connection between the orifice tube 2 and the transverse fixing rod 4 is more stable. In addition, since the transverse fixing rod 4 is always perpendicular to the orifice tube 2 during the fixing process, there is no need to rotate the movable C-shaped seat 8 to adjust its angle during the fixing process, thereby achieving a more stable fixation.

[0039] The specific implementation process is as follows:

[0040] In this embodiment, after the orifice tube 2 is installed and fixed, the sweeping rod 3 and the transverse fixing rod 4 can be fixed using the fixing unit. Since the fixing method of the transverse fixing rod 4 is similar to that of the sweeping rod 3, the fixing of the sweeping rod 3 is taken as an example for explanation below.

[0041] First, adjust the inclination angle of the sweeping rod 3 according to the slope of the toe board 1, so that the sweeping rod 3 is arranged parallel to the toe board 1, and the distance between the sweeping rod 3 and the toe board 1 is controlled to be 150mm, and then push the fixed C-shaped seat 5 to engage with the orifice tube 2, connect the fixed locking screw 7 to the two fixed locking plates 6, and fix them with the nuts in the prior art, so that the fixed C-shaped seat 5 and the orifice tube 2 are clamped and fixed; then use a similar method to clamp the movable C-shaped seat 8 and the sweeping rod 3. Since a pin shaft 11 is provided between the fixed C-shaped seat 5 and the movable C-shaped seat 8 for rotational connection, when fixing the sweeping rod 3, the movable C-shaped seat 8 can be rotated to a suitable angle according to the slope of the toe board 1, so that the sweeping rod 3 can be clamped and fixed accurately and stably ( Figure 3 (The fixed C-shaped seat 5 has been rotated clockwise by a certain angle relative to the pin 11.) When the rod 4 is laterally fixed in this embodiment, the difference from the sweeping rod 3 is that a fixing screw 12 is added between the fixed C-shaped seat 5 and the movable C-shaped seat 8 to fix them relative to each other.

[0042] In this embodiment, the sweeping rod 3 and the transverse fixing rod 4 are fixed to the orifice tube 2 using a fixing unit, so that all the orifice tubes 2 can be connected as one, thereby effectively improving the stability of the orifice tube 2, and ensuring that the grouting process is completed more smoothly and with high quality during the grouting process, thereby effectively improving the quality of the curtain grouting.

[0043] Example 2

[0044] The difference between the second embodiment and the first embodiment is that: Figure 4 As shown, in order to ensure the connection strength when only the pin 11 is used to connect the fixed C-shaped seat 5 and the movable C-shaped seat 8, the diameter of the pin 11 is set to be larger than the nominal diameter of the fixing screw 12 in this embodiment. Specifically, the diameter of the pin 11 is equal to twice the nominal diameter of the fixing screw 12, so that when the pin 11 is set between the fixed C-shaped seat 5 and the movable C-shaped seat 8, it has better structural strength, thereby stably connecting and fixing the sweeping rod 3 and the orifice pipe 2.

[0045] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
