As shown in fig. 1 to 3, the first embodiment of the present invention provides a hydraulic cutting drag reduction pre-support device, which comprises a protective shell 100, a cutting edge 104 and a propelling member 106. Wherein, the protective shell 100 is arc-shaped, and a high-pressure water spray hole 102 is arranged along the radian direction of the protective shell 100; the cutting edge 104 is detachably mounted at the first end of the protective shell 100 and is adapted to the shape of the protective shell 100; the pusher 106 is disposed within the casing 100 and a movable end of the pusher 106 extends beyond a second end of the casing 100.
According to the hydraulic cutting drag reduction pre-support device provided by the invention, the arc-shaped protective shell 100 is arranged, and the high-pressure water spray holes 102 are arranged on the protective shell 100, so that high-pressure water can be sprayed out from the high-pressure water spray holes 102, a soil body clinging to the protective shell 100 is lost, the frictional resistance in the protective shell 100 is removed, and the tunneling resistance of the protective shell 100 is further reduced. By providing the cutting blade 104 in the casing 100, the resistance at the time of excavation can be further reduced. When the protective shell 100 is tunneled to a certain depth, soil can be immediately excavated, and vault and arch foot collapse is avoided. In the stratum with poor land stability such as a sand layer, a saturated water stratum and the like, due to the protection effect of the protective shell 100, the exposure time of the soil outside the protective shell 100 is greatly shortened, the possibility of collapse is greatly reduced, and the safety of tunnel excavation is improved.
Particularly, the protective shell 100 is arc-shaped, the arc-shaped can be arc-shaped or elliptical arc-shaped, and the protective shell 100 is arc-shaped, so that a larger construction space can be ensured in the protective shell 100 after the protective shell 100 is tunneled, and the construction operation of tunnel excavation equipment is facilitated.
Along the radian direction of the protective shell 100, a plurality of high-pressure water spray holes 102 are arranged on the protective shell 100, wherein the number of the high-pressure water spray holes 102, the distance between two adjacent high-pressure water spray holes 102 and the diameter of each high-pressure water spray hole 102 are not specifically limited, and can be flexibly selected according to actual geological parameters. The plurality of high-pressure water spray holes 102 are formed in the protective shell 100, so that high-pressure water can be sprayed from the high-pressure water spray holes 102 to wash the soil in the tunneling direction of the protective shell 100 in the tunneling process of the protective shell 100, the soil body attached to the protective shell 100 is lost, and the resistance in the tunneling process of the protective shell 100 is reduced.
The first end of the protective shell 100 is detachably connected with a cutting edge 104, wherein the first end of the protective shell 100 is specifically the end of the protective shell 100 for tunneling, and the shape of the cutting edge 104 is adapted to the shape of the protective shell 100, that is, the cutting edge 104 is also arc-shaped or circular arc-shaped. By arranging the cutting edge 104, the resistance of the protective shell 100 during tunneling can be further reduced, and the soil body can be cut more conveniently during tunneling of the protective shell 100. In addition, the cutting edge 104 and the protective shell 100 are detachably connected, and flexible replacement of the cutting edge 104 is guaranteed when the cutting edge is damaged.
Also mounted within the casing 100 is a pusher 106, wherein the pusher 106 is configured to effect the pushing of the casing 100. That is, when the propelling member 106 is actuated, the casing 100 can be driven to complete the tunneling action.
Further, a water storage tank (not shown) and a pressurizing member (not shown) are included. As described above, since the high pressure water is sprayed from the high pressure water spray hole 102, a pressurizing member, such as a pressurizing pump, is connected to the first pipe connecting the water storage tank and the high pressure water spray hole 102. When the water in the first pipeline is pressurized, the water can be pumped into the high-pressure water jet holes 102 and then is jetted out of the soil body in the tunneling direction of the protective shell 100 through the high-pressure water jet holes 102 to complete the cutting of the soil body.
In order to further reduce the resistance outside the casing, a lubricant overflow hole 108 is further provided on the outer side wall of the casing 100 along the arc direction of the casing 100. The lubricant overflow hole 108 provided on the outer side wall of the casing 100 can overflow the lubricant. That is, when the protective casing 100 is driven, in addition to the cutting of the soil body by spraying high-pressure water from the high-pressure water spray holes, the lubricant is simultaneously overflowed from the outer wall of the protective casing 100 to lubricate the space between the outer wall of the protective casing 100 and the soil body.
In other words, in the embodiment of the present invention, a lubricant tank (not shown in the figure) is further included, and the lubricant tank communicates with the lubricant overflow hole 108 through the second pipeline. Here, a pressure piece can also be connected to the second line for pressing the lubricant from the lubricant tank into the lubricant overflow opening 108.
In the embodiment of the present invention, the propelling member 106 is a jack, the jack is disposed in the casing 100, and a movable end of the jack extends out of the second end of the casing 100 and is pressed against the reaction device or the primary support structure after the completion of the process.
In other words, when the jack is operated, the movable end of the jack extends out of the second end of the protective shell 100 and abuts against the reaction device or the primary support structure after the jack is completely applied.
Further, in order to ensure the stability of the jack when the jack is pressed tightly, a mounting hole is further provided in the protective casing 100, and the jack is mounted in the mounting hole. In addition, the number of the jacks is not particularly limited as long as the jack can tightly jack the shield 100 and complete the tunneling work. Moreover, the number of the mounting holes corresponds to the number of the jacks one by one.
In other embodiments, the propelling member 106 may be a hydraulic cylinder or the like.
Further, the casing 100 includes a first case 110 and a second case 112. The second housing 112 and the first housing 110 are spliced together to form the protective casing 100.
By providing the protective case 100 in such a manner that it is formed by splicing the first case 110 and the second case 112, the replaceability of the protective case 100 is ensured, for example, when the first case 110 or the second case 112 is damaged, the first case 110 or the second case 112 can be directly replaced.
Still further, the first housing 110 and the second housing 112 are symmetrical to each other, so that the interchangeability between the first housing 110 and the second housing 112 is also improved.
Of course, in other embodiments, the casing 100 may be integrally formed or formed from multiple pieces.
Further, the cutting edge 104 includes a first blade 114 and a second blade 116. Wherein the first blade 114 is detachably mounted to the first housing 110; the second blade 116 is detachably mounted to the second housing 112; the first blade 114 and the second blade 116 are spliced together to form the cutting edge 104.
The exchangeability of the protective case 100 is ensured by arranging the protective case 100 to be formed by splicing together the first blade 114 and the second blade 116, for example, when the first blade 114 or the second blade 116 is damaged, the first blade 114 or the second blade 116 can be directly replaced.
Still further, the first blade 114 and the second blade 116 are symmetrical to each other, which also improves interchangeability between the first blade 114 and the second blade 116.
Further, the arc of the casing 100 is 180 degrees. The radian of the protective shell 100 is set to be 180 degrees, so that the stability of the arch springing position of the protective shell 100 supported on the ground is guaranteed, and meanwhile, the maximization of a construction operation area formed by enclosing the interior of the protective shell 100 is also guaranteed.
Embodiments of the second aspect of the invention also provide a hydraulic cutting system, which comprises the hydraulic cutting drag reduction pre-support device.
By arranging the hydraulic cutting resistance-reducing pre-supporting device in the vertical cutting system, the high-pressure water jet holes 102 can jet high-pressure water, so that the soil body clinging to the protective shell 100 is lost, the frictional resistance in the protective shell 100 is removed, and the tunneling resistance of the protective shell 100 is reduced. By providing the cutting blade 104 in the casing 100, the resistance at the time of excavation can be further reduced. When the protective shell 100 is tunneled to a certain depth, soil can be immediately excavated, and vault and arch foot collapse is avoided. In the stratum with poor land stability such as a sand layer, a saturated water stratum and the like, due to the protection effect of the protective shell 100, the exposure time of the soil outside the protective shell 100 is greatly shortened, the possibility of collapse is greatly reduced, and the safety of tunnel excavation is improved.
In addition, the technical effects of the hydraulic cutting drag reduction pre-support device provided by the embodiment of the first aspect of the invention are also provided in the hydraulic cutting system provided by the embodiment of the second aspect of the invention, and are not described herein again.
