Since the technical scheme is used, the utility model has the advantages of simple structure, use reliably, low cost, adopt it can effectively reduce and produce non-directional flow between face muddy water and the bentonite, improved the jacking effect.
Description
Technical Field
The utility model relates to a rock pipe jacking machine, especially a sediment device is prevented to rock pipe jacking machine.
Background
At present, a pipe jacking technology is used as a non-excavation technology, and has the advantages of high construction speed, high automation degree, manpower resource saving, coordination with the environment and the like, and long-distance rock pipe jacking projects are increasing. However, under complex geological conditions, especially hard rock geological conditions, a certain overexcavation gap exists between the pipe jacking machine shell and the surrounding rock, the surrounding rock has strong self-stability, and the overexcavation gap tunneling process between the shield body and the surrounding rock always exists. The unable very first time of bentonite at shield body rear portion is full of the shield body all around in the excavation process, and because face muddy water fluctuation is great, make the non-directional flow that produces between bentonite and the face muddy water easily, and the stone ballast that excavates down is because self specific gravity is big, leads to partial stone ballast to flow into around the shield body easily, and then gets into push pipe tubular product all around, leads to tubular product to be lifted, and the frictional resistance increases, influences the normal clear of pipe construction to the top, can lead to unable continuation top even and advance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a rock push bench sediment prevention device that can effectively reduce and produce the non-directional flow between face muddy water and the bentonite.
The utility model aims at realizing through such technical scheme, a sediment device is prevented to rock pipe jacking machine, including rock pipe jacking machine, rock pipe jacking machine includes anterior shield and tail shield be provided with shield body frid on the anterior shield outer wall be provided with the recess on the shield body frid the slant is provided with one at least slag trap in the recess, the up end of slag trap is higher than the tail shield outer wall.
In order to improve the reliability, the two slag baffles are provided, and a cavity is arranged between the two slag baffles; and a grease injection hole communicated with the cavity is formed in the shield body slot plate, and sealing grease is arranged in the cavity.
In order to be capable of injecting grease rapidly, the four grease injection holes are uniformly distributed on the shield groove plate.
Further, each slag trap comprises at least four L-shaped slag trap bodies, and the four slag trap bodies are stacked.
In order to improve the resistance, wear-resistant steel wires are arranged between the adjacent slag plates.
Further, in order to enable the connection to be firm, the lower end face of one end of the slag baffle is welded with the shield groove plate, a pressing ring is arranged on the upper end face of the end, and the pressing ring is lower than the outer wall of the front shield.
Since the technical scheme is used, the utility model has the advantages of simple structure, use reliably, low cost, adopt it can effectively reduce and produce non-directional flow between face muddy water and the bentonite, improved the jacking effect.
Drawings
The drawings of the utility model are as follows:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged view of a portion a of fig. 1.
Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and any modifications or substitutions in the basic spirit of the embodiments will still fall within the scope of the present invention as claimed in the appended claims.
Example 1: as shown in fig. 1 and 2, the sediment device is prevented to rock pipe jacking machine, includes rock pipe jacking machine, rock pipe jacking machine includes anterior shield 1 and tail shield 2 be provided with shield body frid 3 on the anterior shield 1 outer wall be provided with the recess on the shield body frid 3 the slant is provided with one at least slag trap 4 in the recess, the up end of slag trap 4 is higher than the 2 outer walls of tail shield.
The slag blocking plates 4 are arranged in two ways, and a cavity is arranged between the two slag blocking plates 4; and a grease injection hole 5 communicated with the cavity is formed in the shield body slot plate 3, and sealing grease 6 is arranged in the cavity.
The four grease injection holes 5 are uniformly distributed on the shield groove plate 3.
Each slag trap 4 comprises at least four L-shaped slag trap bodies, and the four slag trap bodies are stacked.
And wear-resistant steel wires are arranged between the adjacent slag baffles 4.
The lower terminal surface of the one end of slag trap 4 and shield body frid 3 welding, be provided with clamping ring 7 at the up end of this end, clamping ring 7 is less than 1 outer wall of anterior shield.
The utility model discloses in, keep apart bentonite 8 and the anterior excavation face physics of blade disc 9 through slag trap 4 and sealed fat 6, make not take place to flow between the muddy water of blade disc 9 and the bentonite to it gets into shield body and tubular product all around to reduce excavation face stone sediment.
Furthermore, through the above arrangement, the unidirectional flow generated between the mud water on the palm surface 10 and the bentonite 8 can be effectively reduced, the rock ballast excavated by the palm surface 10 is reduced to flow into the periphery of the shield body and the pipe joints 11, the rock ballast flowing into the periphery of the pipe is further reduced as much as possible, and meanwhile, the bentonite 8 at the rear part of the main machine can be ensured to be filled into the periphery of the shield body as much as possible, so that the rock ballast is further prevented from entering the periphery of the pipe, the bentonite 8 can be effectively reduced to flow into the palm surface 10 and be excessively lost, a better lubricating effect is achieved, and the jacking efficiency is effectively improved.
