Description
Technical Field
The invention belongs to the technical field of water supply pipe network construction, and particularly relates to a water delivery pipe mountain penetrating device.
Background
The construction of water supply network facilities in mountain cities usually faces the difficult problem of laying, especially when the water supply land and the water use land are located on two sides of a mountain, a water pipeline is usually constructed in a mountain-turning or mountain-crossing manner, the mountain-turning is relatively simple in construction, but difficult in maintenance and inconvenient in use, large water pressure needs to be increased in front of the mountain to turn the mountain, the pipeline needs to have higher pressure bearing capacity, and the water pressure needs to be properly reduced behind the mountain to meet the water pressure requirement of a pipe network. If the water pipeline is built in a mountain-crossing mode by means of the planned traffic tunnel, the existing long-distance detour is faced, even the construction period of the constrained tunnel construction is limited, and the construction of a water supply network is not facilitated to be completed in time.
Of course, there is a precedent that a unit tries to construct a tunnel dedicated for water delivery by itself, and the construction is performed by burying construction equipment through pipelines which are not excavated or are excavated a little, and specifically, the construction is performed in a pipe jacking mode, which mainly comprises a tunneling machine head, a main jacking mechanism, a relay room and a jacking pipe. And after one section of jacking pipe finishes jacking into the soil layer by matching with an internal power system and a control system, the second section of jacking pipe continues jacking. The principle is that the tunneling machine head is pushed to a preset position from a launching pit through a soil layer by means of the main jacking mechanism, a jacking pipe, a relay and other pushing forces, so that the punching is completed.
In the existing construction process, especially in the long-distance construction process, in order to guarantee the thrust of the main jacking mechanism, a nozzle and a corresponding lubricating system are usually arranged, so that muddy water slurry is sprayed out through the nozzle, the friction force between the jacking pipe and the surrounding soil is reduced, and the thrust of the main jacking mechanism is further guaranteed. However, during the construction process, water in the soil often permeates into the jacking pipes along the joint of the two jacking pipes, and once a large amount of water enters the jacking pipes, serious safety accidents can be caused.
Disclosure of Invention
The invention aims to provide a water pipe mountain penetrating device which can prevent a large amount of outside water from entering a jacking pipe.
In order to achieve the purpose, the scheme provides a water delivery pipe mountain penetrating device which comprises a base, a main jacking mechanism, a tunneling machine head and a jacking mechanism formed by connecting a plurality of jacking pipes, wherein the tunneling machine head, the jacking mechanism and the main jacking mechanism are sequentially connected, the base is positioned in a launching pit and is positioned below the jacking pipes, dry fiber packages and a refrigerating mechanism for cooling the fiber packages are further arranged on the jacking pipes close to the tunneling machine head, and the fiber packages are arranged around the jacking pipes; the lubricating mechanism comprises a slurry pump and a nozzle communicated with the slurry pump, the inlet of the slurry pump is positioned between the fiber bag and the jacking pipe, the nozzle is fixed in the groove, and the nozzle is positioned above the first impermeable membrane; the jacking mechanism is obliquely arranged, the jacking pipe is clamped between the jacking pipes, a groove is formed in the side wall of each jacking pipe, a first anti-seepage film and a second anti-seepage film are arranged in the groove, one end of the first anti-seepage film is connected to the bottom of the groove, the middle of the other end of the first anti-seepage film is connected with the inner side edge of the second anti-seepage film in a sealing mode, and the second anti-seepage film is located below the first anti-seepage film.
The principle of the scheme is as follows: the tunneling machine head is responsible for excavating and drilling holes, and the main jacking mechanism pushes the jacking pipes one by one to move. And then the lubricating mechanism is started to lubricate the side wall of the jacking pipe. Due to the inclined arrangement of the jacking mechanism, slurry serving as a lubricant is easy to accumulate at the fiber package, so that the pressure at the fiber package is increased. The refrigeration mechanism is started to condense the fiber package into ice, and the lubrication mechanism lubricates the side wall of the jacking pipe by a slurry pump at the fiber package to the nozzle, so that the circulation of the lubricant is realized.
The beneficial effect of this scheme lies in:
1. the jacking mechanism is obliquely arranged, and is arranged horizontally, so that more labor is saved, and the pushing pressure of the main jacking mechanism can be effectively reduced.
2. The fiber bag can effectively prevent water in soil from entering from the jacking pipe and the heading machine head. Meanwhile, the fiber package can freeze when meeting water and under the action of a refrigerating mechanism. Thus, on the one hand, water is prevented from entering the jacking pipe, and on the other hand, ice has a good lubricating effect, so that the friction force between the jacking pipe and soil can be reduced. The cooperation of the fiber bag, the refrigerating mechanism and the lubricating mechanism can reduce the pressure at the end part and reduce the pressure of slurry on the tunneling machine head; on the other hand, the circulating slurry can also better save the total dosage of the slurry and reduce the cost.
3. The nozzle is arranged in the groove, so that muddy water sprayed by the nozzle can be concentrated in the groove to the greatest extent, and the first anti-seepage film and the second anti-seepage film can be acted under the action of the muddy water, so that water in soil is further prevented from entering the top feed pipe; when water in soil passes through the joint of the jacking pipe, the first impermeable membrane and the second impermeable membrane are arranged, and the first impermeable membrane is fixed in the groove and can directly block water on one side from entering; and when water enters from the second impermeable membrane, the water on the other side is difficult to enter the joint between the top inlet pipes due to the gravity of the water above the first impermeable membrane, and when more water is available, the isolation effect is better.
Compared with the traditional pipe pushing jack, the scheme utilizes unique structural characteristics, effectively avoids a large amount of external water from entering the jacking pipe, and increases the safety of equipment.
Furthermore, a sealing gasket is arranged at the joint between the jacking pipes. The sealing performance of the jacking pipe can be effectively improved by arranging the sealing washer.
Further, the number of the nozzles is plural. The lubricating effect of a plurality of nozzles is better and more timely.
Further, the nozzles are non-uniformly distributed on the jacking pipe, and the density of the nozzles at the lower part of the jacking pipe is greater than that of the nozzles at the upper part of the jacking pipe. Because the jacking mechanism is arranged obliquely, the top of the jacking pipe is at a greater distance from the soil than the bottom under the action of gravity, and the top is subjected to less friction than the bottom. Therefore, the nozzles are arranged unevenly, and resources can be reasonably utilized.
Further, the main jacking mechanism is a hydraulic jack. The hydraulic jack is a common jacking mechanism, is easy to obtain and has good propelling effect.
Furthermore, the first impermeable film and the second impermeable film are coated with wear-resistant coatings. The arrangement of the wear-resistant coating can effectively prolong the service life of the first impermeable film and the second impermeable film.
Furthermore, a filter screen is arranged on the nozzle. The arrangement of the filter screen can reduce the probability of blockage of the nozzle.
Furthermore, a relay room is arranged between the jacking pipes. The arrangement of the intermediate chamber is responsible for pushing the previous jacking pipe of the intermediate chamber to move, so that the pushing pressure of the main jacking mechanism can be greatly reduced.
Further, the main ejection mechanism is an angle-adjustable main ejection mechanism. Under the arrangement, different environmental requirements can be met by adjusting the angle of the main jacking mechanism.

Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the launching pit 10, the fiber package 20, the base 30, the main jacking mechanism 40, the jacking pipe 50, the nozzle 51, the groove 52, the first impermeable membrane 53, the second impermeable membrane 54, the relay room 60 and the heading machine head 70.
As shown in fig. 1, in the present embodiment, a launching pit 10 is disposed on the left side, and a base 30, a main top mechanism 40, a control system and a lighting system are installed in the launching pit 10. The whole equipment is obliquely arranged downwards to the right, so that labor can be saved more during propelling. The main jack mechanism 40 employs a hydraulic jack. The hydraulic jack is a common jacking mechanism, is easy to obtain and has good propelling effect. The main ejection mechanism 40 is the angle-adjustable main ejection mechanism 40, the angle-adjustable main ejection mechanism 40 can be directly purchased, or the main ejection mechanism 40 can be arranged on an angle-adjustable adjusting plate and selected according to the actual condition of an operator.
To the right are the respective jacking tubes 50 and ripper head 70 which are clamped to each other. A sealing gasket is provided at the junction between the jacking pipes 50 to increase the sealability of the jacking pipes 50. A relay room 60 is arranged between every four sections of jacking pipes 50, and the relay room 60 is also a hydraulic jack. The arrangement of the intermediate room 60 is responsible for moving the jack pipe 50 before pushing the intermediate room 60, which can greatly reduce the pushing pressure of the main jack mechanism 40. Is particularly suitable for long-distance construction. A dry fiber pack 20 is disposed between the rightmost jacking tube 50 and the roadhead 70. The fiber package 20 is wound entirely around the jacking pipe 50 and is also provided with a refrigerating device correspondingly. The fiber package 20 is provided to effectively prevent water from the soil from entering the jacking tube 50 and the heading machine head 70. At the same time, the fiber package 20 may freeze to ice when it encounters water and under the influence of the refrigeration mechanism. This prevents water from entering the jacking pipe 50 on the one hand and the ice has a good lubricating effect on the other hand, reducing the friction between the jacking pipe 50 and the soil.
As shown in fig. 2, the pushing pipes 50 are clamped, and a groove 52 is formed on a side wall of the pushing pipe 50. A first impermeable membrane 53 and a second impermeable membrane 54 are provided in the groove 52. The left end of the first impermeable membrane 53 is connected to the bottom of the groove 52 and is positioned in front of the joint of the two jacking pipes 50, the middle part of the other end is connected with the second impermeable membrane 54, and the second impermeable membrane 54 is positioned below the first impermeable membrane 53.
In order to increase the service life of the first and second impermeable films 53 and 54, an abrasion resistant coating may be provided on the first and second impermeable films 53 and 54.
The lubricating mechanism includes a slurry pump and a nozzle 51 communicating therewith. The intake of the slurry pump is located between the fiber package 20 and the jacking tube 50, which is shown on the left side of the fiber package 20. The nozzle 51 is fixed in the groove 52, and the nozzle 51 is positioned to the left of the first impermeable membrane 53. The number of the nozzles 51 is plural, and the nozzles 51 are non-uniformly distributed on the knock-in pipe 50. The density of the nozzles 51 located at the lower portion of the knock pipe 50 is greater than the density of the nozzles 51 located at the upper portion of the knock pipe 50. Because the jacking mechanism is inclined, the top of the jacking tube 50 is at a greater distance from the soil than the bottom, and the top is subjected to less friction than would otherwise be the case, under the influence of gravity. Therefore, resources can be used reasonably by arranging the nozzles 51 unevenly.
In particular, when the heading machine head 70 is used for excavating and drilling holes, the main jacking mechanism 40 pushes the jacking pipes 50 of one section to move. The lubrication mechanism is then activated to lubricate the side wall of the jacking tube 50. Due to the inclined arrangement of the jacking mechanism, slurry as a lubricant is easily accumulated at the fiber pack 20, resulting in an increase in pressure at the fiber pack 20. The refrigeration mechanism is started to condense the fiber package into ice, and the lubrication mechanism simultaneously pumps the slurry at the fiber package 20 to the nozzle 51 to lubricate the side wall of the jacking pipe 50, so that the circulation of the lubricant is realized.
When water in soil passes through the joint of the jacking pipe 50, due to the arrangement of the first impermeable membrane 53 and the second impermeable membrane 54, the first impermeable membrane 53 is fixed in the groove 52, and can directly block water on one side from entering; while the water on the other side is difficult to enter the junction between the ascent pipes 50 due to the gravity of the water above the first impermeable membrane 53 when entering from the second impermeable membrane 54, and the more the water is, the better the insulation effect is. Compared with the traditional push bench, the scheme utilizes unique structural characteristics, effectively prevents a large amount of outside water from entering the jacking pipe 50, and increases the safety of the equipment.
