Description

Technical Field

[0001] This utility model relates to the field of anchor cable construction technology, and in particular to an auxiliary device for cleaning sediment in slope anchor cable construction. Background Technology

[0002] Prestressed anchor cable support is widely used in high slope protection systems due to its fast construction speed, low cost, and ability to effectively resist displacement and damage of deep soil layers and maintain slope stability. It is also widely applied in road and building foundation pit slope protection projects. Anchor cables effectively manage slopes and improve their stability. They are a tensile-resistant structural system that works by drilling or pre-drilling holes through the reinforced layer, anchoring one end of the inner anchor head to the rock structure. The outer anchor head is the free end, and tension is applied to the layer outside the rock structure to anchor unstable rock masses or the object being reinforced.

[0003] Drilling is a key process for controlling the construction period and quality in anchor cable construction. Currently, during anchor cable construction, the borehole is prone to collapse due to impact or slight disturbance. At the same time, the crushed stone cannot be crushed into powdery fragments by the drill bit and discharged, which increases the frictional resistance of the drilling rig in the hole and hinders the rotation of the drill bit. If drilling is forced or withdrawn, it is very easy to cause the completed hole section to collapse, the drill rod to bend and break, the drill bit to get stuck and scrapped, and it will also delay the construction period. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for cleaning sediment during slope anchor cable construction, which prevents hole collapse and drill jamming, and facilitates connection and cleaning of sediment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An auxiliary device for cleaning sediment during slope anchor cable construction includes a first follow-up steel sleeve, a second follow-up steel sleeve, and an annular connector connecting the first and second follow-up steel sleeves, all installed inside the anchor cable hole on the slope.

[0007] Mounting plates are fixed to the rear end of the first follow-up steel sleeve and both ends of the second follow-up steel sleeve, respectively. The mounting plates have a first locking groove and a second locking groove. The annular connector has a receiving groove, and a bidirectional threaded rod with both ends rotatably connected to the annular connector is provided in the receiving groove. Two clamping plates are threadedly connected to the bidirectional threaded rod and arranged in parallel. A first locking block and a second locking block are fixed to the clamping plates and arranged opposite to each other. One end of the bidirectional threaded rod passes through the annular connector and is connected to the rotating block. The two ends of the annular connector have holes through which mounting plates pass to the receiving groove. The first locking block is connected to the first locking groove, and the second locking groove is connected to the second locking block.

[0008] Furthermore, an inner ring and an outer ring are fixed at both ends of the annular connector, respectively.

[0009] Furthermore, the second follow-up steel sleeve is connected to a splash guard with a cleaning port at the bottom.

[0010] Furthermore, the second follow-up steel sleeve is provided with screw holes, and the splash guard and the second follow-up steel sleeve are fixed by a mounting plate and bolts.

[0011] Furthermore, a groove is formed at one end of the splash guard to connect with the mounting plate.

[0012] Furthermore, the sizes of the first locking block and the second locking block are respectively matched with the sizes of the first locking slot and the second locking slot, and the first locking slot and the second locking slot are staggered on the mounting plate.

[0013] Furthermore, the width of the clamping plate matches the width of the receiving groove, and the bidirectional threaded rod is arranged on the central axis of the receiving groove and the clamping plate.

[0014] Furthermore, the splash guard is a hemispherical structure with an internal collection groove.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention connects the first follow-up steel casing and multiple sets of second follow-up steel casings via annular connectors and drills them simultaneously with the drilling rig, forming a steel casing protective wall in the gravel layer before anchor cable construction. After drilling, the casing is drilled, then the drill is withdrawn, the casing is connected, the rod is connected, and drilling continues until the hole depth is reached. This solves the problems of hole collapse, drill jamming, and failure to reach the designed depth in anchor cable hole construction. At the same time, the splash guard collects splashed sediment and discharges it through the cleaning port, avoiding pollution caused by sediment splashing, improving the anchor hole formation rate under complex geological conditions, and saving construction time.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example 1

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 An auxiliary device for cleaning sediment during slope anchor cable construction includes a first follow-up steel sleeve 3, a second follow-up steel sleeve 12, and an annular connector 9 connecting the first and second follow-up steel sleeves, all installed in the anchor cable hole 2 of the slope 1. Mounting plates 7 are fixed to the rear end of the first follow-up steel sleeve and both ends of the second follow-up steel sleeve, respectively. The mounting plates 7 have a first locking groove 13 and a second locking groove 14. The annular connector has a receiving groove 19, within which a bidirectional threaded rod 23, rotatably connected at both ends to the annular connector, is installed. Two parallel clamping plates 20 are threadedly connected to the bidirectional threaded rod. The width of the clamping plates is proportional to the width of the receiving groove. The width of the receiving groove is matched, and the bidirectional threaded rod is set on the central axis of the receiving groove and the clamping plate to make locking more convenient and stable. The first locking block 21 and the second locking block 22 are respectively fixed on the clamping plate and are arranged opposite to each other. One end of the bidirectional threaded rod passes through the annular connector and is connected to the rotating block 10. The two ends of the annular connector are respectively provided with mounting plates that pass through holes 24 leading to the receiving groove. The first locking block is connected to the first locking groove, and the second locking groove is connected to the second locking block. The size of the first locking block and the second locking block are matched with the size of the first locking groove and the second locking groove, respectively. The first locking groove and the second locking groove are staggered on the mounting plate.

[0025] To reinforce the connection between the first and second follower steel sleeves, an inner ring 11 and an outer ring 8 are fixed at both ends of the annular connector. The inner ring 11 and the outer ring 8 are fixedly connected to both sides of the annular connector, and the cross-sections of the inner ring 11 and the outer ring 8 on the same side are on the same plane, which facilitates the insertion of the first or second follower steel sleeve into the annular gap between the inner ring 11 and the outer ring 8. The inner ring 11 and the outer ring 8 can also be welded or integrally formed and connected to both ends of the annular connector.

[0026] In this embodiment, the first and second follower steel sleeves are connected by a ring connector. The mounting plate is inserted into the receiving groove through hole 24. Rotating the rotating block drives the bidirectional threaded rod to rotate, causing the two clamping plates to move towards each other. After the first locking block and the second locking block are staggered and engaged with the first locking groove and the second locking groove, the two steel sleeves are fixed into a follower sleeve. The follower sleeve and the drilling rig drill simultaneously to form a steel sleeve protective wall in the gravel layer, and then the anchor cable construction is carried out. After the hole is opened, the follower sleeve is drilled, then the drill is withdrawn, the pipe is connected, the rod is connected, and then drilling continues to reach the hole depth. This solves the problems of hole collapse and drill jamming and failure to reach the design depth in anchor cable hole construction, and also saves the construction cycle. Example 2

The splash guard and the second follow-up steel sleeve are fixed by a mounting plate 16 and bolts 15, or a groove 17 is opened at one end of the splash guard to connect it to the mounting plate. The other construction methods are the same as in Embodiment 1. By setting up the splash guard, splashed sediment is collected and discharged through the cleaning port, avoiding pollution caused by sediment splashing.
