The utility model has the advantages of being simple in structure and convenient in operation, can effectively prevent retreating of rectangle push pipe jacking in-process, guarantee that the work progress goes on smoothly.
Description
Technical field
The utility model relates to rectangular top pipe backing stop structure, is used in rectangular top pipe jack-in process and stops tube coupling to retreat.
Background technology
In the work progress of push pipe jacking, during the new tube coupling jacking of each handling, jacking oil top can be regained, now shield machine head is subject to soil pressure effect, tube coupling entirety will be caused to retreat, if do not established stopping device, comparatively large disturbances will be caused to cause sediment failure to the front soil body once tube coupling retreats, and then cause the serious consequences such as roadbed subsidence, the retaining measure taked for rectangular top pipe in prior art is on the surrounding well wall of active well wall pipe, make polylith anchor plate, when the tube coupling jacking that each handling is new, by multiple large-tonnage Chain block pipeline is connected with anchor point and prevents from retreating.Prior art is higher to the pre-buried requirement of anchor plate, and the new tube coupling of each handling all needs to reconnect, trivial operations, and danger is comparatively large and accident generation sign is not obvious.
Utility model content
The utility model is the weak point for avoiding above-mentioned prior art to exist, a kind of rectangular top pipe backing stop structure is provided, can effectively stop oil top in rectangular top pipe work progress to regain pipeline is in not by the displacement produced during the power state of top, ensures that work progress carries out smoothly.
The utility model is that technical solution problem adopts following technical scheme:
The feature of the utility model rectangular top pipe backing stop structure is:
Shield structure backing plate symmetry dual-side, be in non-level push pipe position place, be separately installed with up-right support, described up-right support is formed with the spacing right angle be made up of cross bar and vertical frame bar at top, the cross bar in described spacing right angle points to jacking direction, and described vertical frame bar straight up;
The two side of tube coupling arranges retaining pin-and-hole; Described retaining pin-and-hole be with the spacing right angle on described up-right support on a corresponding position;
Arrange retaining pin, described retaining pin leading portion is inserted in the pin-and-hole of tube coupling sidewall, and back segment is spacing on the spacing right angle of up-right support, and described retaining pin is can finger.
The feature of the utility model rectangular top pipe backing stop structure is also: described up-right support is set to " H " shaped steel frame, and described " H " shaped steel frame is that two vertical frame bars and cross bar are formed in and described " H " shaped steel frame are formed on sustained height and along two spacing right angles tandem on jacking direction.
The feature of the utility model rectangular top pipe backing stop structure is also: to be inclined to set helper at the side of described up-right support, to utilize helper that operating personnel are climbed to the top of a mountain and described retaining pin be placed on desired location.
The feature of the utility model rectangular top pipe backing stop structure is also: at the hand-held ring of the fixing welding of afterbody of described retaining pin.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model effectively can stop the retrogressing in rectangular top pipe jack-in process, ensures that work progress carries out smoothly.
2, the utility model structure is simple, easy to operate, easy to implement.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is H profile steel shelf structure schematic diagram in the utility model;
Fig. 3 is latch structure schematic diagram in the utility model;
Number in the figure: 1 cross bar, 2 vertical frame bars, 3 retaining pins, the hand-held ring of 3a, 4 helpers, 5 shield structure backing plates, 6 minor details push pipes.
Detailed description of the invention
See Fig. 1 and Fig. 2, in the present embodiment, rectangular top pipe backing stop structure is:
At dual-side, the minor details push pipe 6 position place of the symmetry of shield structure backing plate 5, be separately installed with up-right support, described up-right support is formed with the spacing right angle be made up of cross bar 1 and vertical frame bar 2 at top, the cross bar in described spacing right angle points to jacking direction, and described vertical frame bar straight up.
The two side of tube coupling arranges retaining pin-and-hole; Described retaining pin-and-hole be with the spacing right angle on described up-right support on a corresponding position.
Arrange retaining pin 3, the leading portion of described retaining pin 3 is inserted in the pin-and-hole of tube coupling sidewall, and back segment is spacing on the spacing right angle of up-right support, and described retaining pin is can finger.
In the present embodiment shown in Fig. 1, up-right support is set to " H " shaped steel frame, and " H " shaped steel frame is that two vertical frame bars 2 and cross bar 1 are formed in and " H " shaped steel frame are formed on sustained height and along two spacing right angles tandem on jacking direction.
In concrete enforcement, to be inclined to set helper 4 at the side of described up-right support, to utilize helper 4 that operating personnel are climbed to the top of a mountain and described retaining pin 3 is placed on desired location.In order to exact operations, at the hand-held ring 3a of the fixing welding of afterbody of described retaining pin 3.
For double Small Distance rectangular top pipe construction, its tube coupling cross dimensions is 7000mm × 5000mm, and wall thickness is 500mm, main channel overall length 95m; Standard tube coupling length is 1.5m, respectively arranges a retaining pin-and-hole time prefabricated in both sides, embeds concrete in retaining hole with steel collar; For special tube coupling, its length reaches 7.56m, needs to be set up in parallel two retaining pin-and-holes respectively in both sides, and two pin-and-holes are corresponding with two spacing square position that " H " shaped steel frame is formed.
In concrete enforcement, the size of retaining pin-and-hole and height determine according to actual conditions, and concrete is stressed should meet code requirement through to check around retaining pin-and-hole.Pin-and-hole is consistent with the requirement for height of retaining pin, avoids occurring that retaining pin cannot insert pin-and-hole, and the position that tube coupling is placed on shield structure backing plate is symmetrical, avoids dual-side pin-and-hole can only insert a retaining pin, and ensures both sides uniform stressed.
In construction, prior " H " shaped steel frame is weldingly fixed on shield structure backing plate, its welding position is determined according to tube coupling size, when the jacking of every pipe joint joint is to retaining hole, retaining pin is inserted in the reserved pin-and-hole of tube coupling, stop jacking tube coupling after oil cylinder sheds top power due to shield machine head soil pressure cause tube coupling entirety retreat.
The utility model is simple to operate, saves the time of jacking, the reduction of erection time, reduces construction cost, simultaneously also for jacking can be carried out providing guarantee smoothly.
