Abstract
The utility model discloses an improved muddy-water pipeline constructing structure, which comprises a driving device, a lead rail and an equalizing ring, wherein one end of the lead rail is connected with the driving device and is driven by the driving device to extend in the axial direction, the equalizing ring is vertically and fixedly arranged on the other end part of the lead rail, and the improved muddy-water pipeline constructing structure is characterized in that: at least one I-shaped bracket is arranged below the lead rail, the top end of the bracket is provided with rollers, and the rollers are contacted with the bottom wall of the lead rail. The improved muddy-water pipeline constructing structure has a simple structure and better construction stability.
Description
Technical field
The utility model relates to a kind of improved pipeline construction structure, relates in particular to a kind of improved muddy water pipeline construction structure.
Background technique
There are many needs to transform, extend in the present urban operating mechanism; particularly underground outmoded all kinds of pipelines need to upgrade; and ground all kinds of overhead conductor need be buried underground underground; yet under the situation very busy in traffic above-ground, that building is in a compact mass; still transform and build the words of underground installation pipeline installation with original heavy excavation mode; not only destroyed surface structures; and it is also very big to the traffic environment influence on ground; mechanization degree is very low; also very limited to underground utilization of space, be unfavorable for protecting original all kinds of underground utility.
The Chinese patent publication number is CN1752501A, open day be that the patent of invention on March 29th, 2006 discloses and a kind ofly can be applied to road, the reaming type mud and water balance micro-push bench of supporting pipelines engineerings such as residential quarter, comprise cutterhead, central shaft, preceding piece housing, drive unit, back piece housing, cutterhead, central shaft, back piece housing is arranged in order by front and back for three sections, cutterhead is a loop configuration, drive unit is connected by bolt with cutterhead, drive unit is positioned at preceding piece housing, link to each other with preceding piece housing by bolt, central shaft is arranged on hollow position in the cutterhead, the central shaft rear end is connected by bolt with preceding piece housing, preceding piece housing is connected with high-strength bolt with the back piece housing, though should invent easy and simple to handle, speed is fast, cost is low, but its structure is too complicated, and construction stability is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome relatively poor defective and the problem of complex structure, construction stability that exists in the prior art, and a kind of simple in structure, construction stability muddy water pipeline construction structure preferably is provided.
For realizing above purpose, technical solution of the present utility model is: a kind of improved muddy water pipeline construction structure, comprise drive unit, guide rail and top iron, but an end of described guide rail is connected and axial stretching under the driving of described drive unit with described drive unit, described top iron vertical fixing is arranged on the end of the described guide rail the other end, the below of described guide rail is provided with at least one I-shaped support, the top of described support is provided with roller, and described roller contacts with the diapire of described guide rail.
Described support is three, and at interval the below that is arranged on described guide rail successively.
The bottom of described support is provided with base plate.
Described drive unit comprises major event oil cylinder, a secondary oil cylinder and cylinder bracket, described major event oil cylinder and fixing being arranged on the described cylinder bracket of a secondary oil cylinder.
Compared with prior art, the beneficial effects of the utility model are:
Since a kind of improved muddy water pipeline construction structure of the present utility model mainly to form structure by drive unit, guide rail and top iron simpler, in addition, below guide rail, be provided with support, this support is provided with the roller with guide rail diapire connecting part, this structural design can guarantee guide rail stable in axial motion, thereby effectively strengthened the whole construction stability of structure, so the utility model is simple in structure, construction stability is better.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: drive unit 10, guide rail 12, top iron 14, major event oil cylinder 16, a secondary oil cylinder 18, cylinder bracket 20, support 22, roller 24, base plate 26, vertically wall 28.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details
Referring to shown in Figure 1, a kind of improved muddy water pipeline construction structure, comprise drive unit 10, guide rail 12 and top iron 14, drive unit 10 comprises major event oil cylinder 16, a secondary oil cylinder 18 and cylinder bracket 20, being arranged on the cylinder bracket 20 of the interval that a major event oil cylinder 16 and a secondary oil cylinder 18 are fixed, but an end of guide rail 12 is connected and axial stretching under the driving of major event oil cylinder 16 with major event oil cylinder 16, iron 14 vertical fixing in top are arranged on the end of guide rail 12 the other ends, preferred top iron 14 is circular top iron, evenly spacedly below guide rail 12 be provided with three I-shaped supports 22, be provided with roller 24 on the top of support 22, this roller 24 contacts with the diapire of guide rail 12, this structural design can guarantee guide rail 12 stable in axial motion, thereby effectively strengthened the whole construction stability of structure, preferably be provided with a base plate 26 in the bottom of support.During use, this device is positioned in the hole, the upright side walls of cylinder bracket 20 contacts with the vertical wall 28 in hole, and base plate 26 contacts with the hole diapire, and this constructing structure construction stability better can effectively avoid the excessive shaft wall structure that causes of the borehole wall 30 discontinuity or local pressure to destroy.
Therefore the utility model is simple in structure, construction stability is better.
The above only is a better embodiment of the present utility model; protection domain of the present utility model does not exceed with above-mentioned mode of execution; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
