Abstract

The invention belongs to cities and towns and lay underground water conduit or blow-off line and box culvert equipment technical field, particularly to a kind of jacking mechanism for underground pipe culvert engineering. This is used for the jacking mechanism of underground pipe culvert engineering, including adjacent front pipe fitting and rear tubular member, it is characterized in that: between described front pipe fitting and rear tubular member, be provided with some hydraulic jacks, front pipe fitting and rear tubular member junction are provided with pipe box, front pipe fitting top is provided with vertical shaft, and front pipe fitting side is connected to rubber dam, and rubber dam, front pipe fitting and vertical shaft are connected by threeway, being provided with some outlets outside rubber dam, rubber dam and front pipe fitting junction are provided with some pump mouths. The invention has the beneficial effects as follows: can be headed into by underground pipe fitting quickly and easily, simple in construction, easy to operate, cost is low, efficiency is high, had both improve speed of application, time saving and energy saving again, also reduces production and construction cost.

Description

Jacking mechanism for underground pipe culvert engineering
(1) technical field
The invention belongs to cities and towns and lay underground water conduit or blow-off line and box culvert equipment technical field, particularly to a kind of jacking mechanism for underground pipe culvert engineering.
(2) background technology
At present, commonly used in the construction of underground pipe culvert engineering both at home and abroad dig vertical shaft, application concrete open caisson also uses hydraulic jack to carry out jacking cement prefabricated component, and the shortcoming of this construction method is: use hydraulic jack jack jacking, when pipeline exceedes a number of cement components, resistance is multiplied, now again pushing up motionless, if continuing reinforcing, top power exceedes the strength degree of cement components, can cause that cement components destroys, cause integral construction failure. Traditional way is: arrange damping device at the cement components place of forefront, and damping device can not inherently alleviate its resistance, and structure is more complicated, manufacturing cost is high, is unfavorable for that construction is smoothed out.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of simple in construction, the jacking mechanism for underground pipe culvert engineering that easy to operate, cost is low, efficiency is high.
The present invention is achieved through the following technical solutions:
A kind of jacking mechanism for underground pipe culvert engineering, including adjacent front pipe fitting and rear tubular member, it is characterized in that: between described front pipe fitting and rear tubular member, be provided with some hydraulic jacks, front pipe fitting and rear tubular member junction are provided with pipe box, front pipe fitting top is provided with vertical shaft, and front pipe fitting side is connected to rubber dam, and rubber dam, front pipe fitting and vertical shaft are connected by threeway, being provided with some outlets outside rubber dam, rubber dam and front pipe fitting junction are provided with some pump mouths.
Described rubber dam is provided with vertical shaft drinking-water pipe, and vertical shaft drinking-water pipe is installed in vertical shaft.
Described outlet is three, and pump mouth is six.
The invention has the beneficial effects as follows: can be headed into by underground pipe fitting quickly and easily, simple in construction, easy to operate, cost is low, efficiency is high, had both improve speed of application, time saving and energy saving again, also reduces production and construction cost.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is the structural representation of the present invention;
In figure, pipe fitting before 1,2 rear tubular members, 3 hydraulic jacks, 4 pipe boxes, 5 vertical shafts, 6 rubber dams, 7 outlets, 8 pump mouths, 9 vertical shaft drinking-water pipes, 10 threeways.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes adjacent front pipe fitting 1 and rear tubular member 2, some hydraulic jacks 3 it are provided with between front pipe fitting 1 and rear tubular member 2, front pipe fitting 1 and rear tubular member 2 junction are provided with pipe box 4, front pipe fitting 1 top is provided with vertical shaft 5, front pipe fitting 1 side is connected to rubber dam 6, rubber dam 6, front pipe fitting 1 and vertical shaft 5 are connected by threeway 10, are provided with some outlets 7 outside rubber dam 6, and rubber dam 6 and front pipe fitting 1 junction are provided with some pump mouths 8. Rubber dam 6 is provided with vertical shaft drinking-water pipe 9, and vertical shaft drinking-water pipe 9 is installed in vertical shaft 5. Outlet 7 is three, and pump mouth 8 is six.
Adopt the jacking mechanism for underground pipe culvert engineering of the present invention, pipe fitting 1 and rear tubular member 2 before putting in construction hole, multiple hydraulic jack 3 is set between front pipe fitting 1 and rear tubular member 2, then a pipe box 4 is set at front pipe fitting 1 tail end and rear tubular member 2 front end, start hydraulic jack 3, pipe fitting 1 before inside jacking, linearity when pipe box 4 ensures front pipe fitting 1 by jacking, after current pipe fitting 1 completely disengages from pipe box 4, it is placed again into another front pipe fitting 1 and continues jacking. In the process of jacking, rubber dam 6 can be passed through and extract the subsoil water in pipeline at any time, it is ensured that the smoothness that front pipe fitting 1 advances. Pump mouth 8 pulls water out from pipeline, discharges from outlet 7, and the unnecessary outlet 7 of quantity of pump mouth 8, unnecessary water can be extracted out from vertical shaft drinking-water pipe 9, discharges from vertical shaft 5. Threeway 10 can ensure that the water around by the front pipe fitting 1 of jacking is discharged by rubber dam 6 or vertical shaft 5 in time at any time.
