Abstract
The invention relates to the technical field of pipe jacking construction of long-distance pipelines, in particular to a grille jacking and rushing device. A grille top head of the device comprises a steel sleeve I, a radial grille is arranged on the inner wall of the front end of the steel sleeve I, and a top ring I is fixedly arranged on the inner wall of the middle part of the steel sleeve I; a jacking device comprises a steel sleeve II, a top ring II is arranged on the inner wall of the steel sleeve II and can move in the steel sleeve II, the cylinder bodies of a plurality of hydraulic cylinders are uniformly fixed on the front end face of the top ring II, the pistons of the hydraulic cylinders directly face to the rear end face of the top ring I, and The rear end of the steel sleeve I is sleeved by the front end of the steel sleeve II. The grille jacking and rushing device solves the collapse problem occurring in the pipe jacking process of pebble sections, sand gravel sections and silty sand sections, reduces a security risk, can precisely regulate center deviation and axis deviation of sleeve jacking, improves the penetration quality, greatly improves the construction progress, is easy to operate on site, and saves construction cost. The grille jacking and rushing device overcomes the defects that the current jacking device is slow in jacking speed and has potential safety hazards.
Description
Technical field:
The present invention relates to a kind of long distance pipeline pipe jacking construction technique field, particularly a kind of grid top flushing device.
Background technique:
In cobble location, sand gravel location, the construction of silty sand location, because soil property viscosity is little, one-tenth arch is poor, holding tube of easily caving in, there is highway cave-in accident in long distance pipeline.Mainly adopt in current construction and add pipe cap foremost at jacking sleeve pipe, operator cut the earth all the time in pipe cap, can reduce risk of caving in, but also there is certain incipient slump damage, and move speed is comparatively slow, and efficiency of construction is low.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of grid top flushing device, the arrangement achieves the problem of caving in solving and occur in cobble location, sand gravel location, silty sand location push pipe process, reduce security risk, can the centre deviation of fine adjustment sleeve pipe jacking and misalignment of axe, improve and pass through quality, greatly improve construction speed, scene is easy to operation, saves construction cost.Overcome existing jacking mechanism move speed slow, there is the deficiency of potential safety hazard.
The technical solution used in the present invention is: a kind of grid top flushing device, is made up of grid top and jacking mechanism; Grid top comprises Steel Sleeve I, and Steel Sleeve I front inner wall is provided with radial grid, in the middle part of Steel Sleeve I, inwall is fixed with apical ring I; Jacking mechanism comprises Steel Sleeve II, Steel Sleeve II inwall is provided with apical ring II, apical ring II can move in Steel Sleeve II, the cylinder body of multiple hydraulic jack is evenly fixed on apical ring II front-end face, the piston of hydraulic jack is just to the ear end face of apical ring I, and Steel Sleeve II front end sleeve is on Steel Sleeve I rear end.
The number of hydraulic jack is 4.
The invention has the beneficial effects as follows: the present invention is owing to have employed the mode of radial grid and hydraulic jack jacking, thus there is the function solving the problem of caving in occurred in cobble location, sand gravel location, silty sand location push pipe process, reduce security risk, can the centre deviation of fine adjustment sleeve pipe jacking and misalignment of axe, improve and pass through quality, greatly improve construction speed, scene is easy to operation, saves construction cost.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is the right elevation of Fig. 1.
Embodiment:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of grid top flushing device, is come directly towards by grid and jacking mechanism forms; Grid top comprises Steel Sleeve I 1, and Steel Sleeve I 1 front inner wall is provided with radial grid 3, in the middle part of Steel Sleeve I 1, inwall is fixed with apical ring I 4; Jacking mechanism comprises Steel Sleeve II 2, Steel Sleeve II 2 inwall is provided with apical ring II 5, apical ring II 5 can move in Steel Sleeve II 2, the cylinder body of 4 hydraulic jacks 6 is evenly fixed on apical ring II 5 front-end face, the piston of hydraulic jack 6 is just to the ear end face of apical ring I 4, and Steel Sleeve II 2 front end sleeve is on Steel Sleeve I 1 rear end.
In cobble location, gravel location, during the push pipe of silty sand location, first utilize main top oil cylinder the present invention to be headed into and pass through position, then mounting sleeve continues jacking, hydraulic jack 6 is utilized to start jacking according to jacking earth pressure situation, each jacking length is not more than 300mm, then hydraulic jack 6 is return stroke, main top oil cylinder is utilized to continue jacking sleeve pipe, combine closely until jacking mechanism and grid come directly towards, then continue to utilize hydraulic jack 6 jacking, be not more than 300mm, stroke return by hydraulic jack 6, main top oil cylinder is utilized to continue jacking sleeve pipe, until push pipe is complete.Adopt the jacking of 4 hydraulic jacks 6 in the flushing device jack-in process of grid top, construction jacking strength is even, greatly reduces the resistance of push pipe operation in construction, improves construction speed; Jacking construction soil digging operation is carried out all the time in grid top, and radial grid 3 adopts bolt to fix, and according to soil property situation increase and decrease grid quantity, effectively can avoid the silty sand earth fall and fall, reduce and pass through risk; Can adjustment axis and centre deviation by 4 hydraulic jacks 6, improve and pass through quality, guarantee to pass through successfully; The present invention can reuse.
Be understandable that, above about specific descriptions of the present invention, the technological scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
