Abstract
The utility model relates to a large-diameter hand-dug pipe-jacking tunneling machine which comprises a casing, a cutting edge, a soil taking opening, a deviation rectifying oil cylinder and a hydraulic station. The cutting edge, the soil taking opening, the deviation rectifying oil cylinder and the hydraulic station are fixedly installed in the casing. The large-diameter hand-dug pipe-jacking tunneling machine is characterized in that the casing is composed of a front casing and a rear casing which are coaxial and mounted in slidingly-embedded mode, the deviation rectifying oil cylinder is installed between the front casing and the rear casing in the front casing, the hydraulic station is installed at the rear end of the rear casing, and a grid is axially and fixedly installed between the cutting edge at the front end of the front casing and the soil taking opening. The tunneling machine is divided into two sections including the front casing and the rear casing, and a seal is added at the movable position between the front casing and the rear casing, so that underground water and muddy water is prevented from entering a pipeline, and construction of operators is not influenced. The deviation rectifying oil cylinder is installed between the front casing and the rear casing, and a deviation rectifying angle is about 2.5 degrees.
Description
Technical field
The utility model belongs to municipal engineering field, relates to the development machine that jacking construction is used, especially a kind of heavy caliber hand pick formula pipe jacking tunnelling machine.
Background technology
Heavy caliber hand pick formula pipe jacking tunnelling machine is under safer condition, to cut the earth the operations such as correction, jacking and measurement and be placed in push pipe instrument foremost for push pipe operating personnel, and it is formed by Plate Welding mostly.Hand pick formula pipe jacking tunnelling machine grows up in the situation that soil pressure and slurry balance pipe-jacking tunneling machine can not meet, be particularly useful for the severe occasion of geological conditions, as sharp sand soil, sand gravel, cobble, decayed rock etc., sometimes with common soil pressure and slurry balance pipe-jacking tunneling machine, can not meet the requirement of construction, need this hand pick formula pipe jacking tunnelling machine.
At present, this hand pick formula pipe jacking tunnelling machine is mostly a housing, and the combination between concrete is not too reliable, often occurs infiltration, leaks the problems such as sand, affects operation, also can increase surface settlement simultaneously.And, fetch earth mouthful often the same with the form of fracture of cutting edge, all do conglobately, but long and correction is comparatively frequently in situation in jacking length, development machine tends to rotation, cannot determine the anglec of rotation.
Utility model content
The purpose of this utility model is to overcome the deficiency existing in above-mentioned technology, provide a kind of simple in structure, compliance good, safe and reliable heavy caliber hand pick formula pipe jacking tunnelling machine.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of heavy caliber hand pick formula pipe jacking tunnelling machine, comprise housing, cutting edge, fetch earth mouthful, correction oil cylinder and Hydraulic Station, in housing, be fixedly mounted with cutting edge, fetch earth mouthful and correction oil cylinder, Hydraulic Station, it is characterized in that: described housing coaxially consists of procapsid and back casing, the slip setting-in of procapsid and back casing, correction oil cylinder is installed between the forward and backward housing in procapsid, Hydraulic Station is installed in back casing rear end, at the cutting edge of procapsid front end and fetch earth and be axially fixed with grid between mouth.
And the cutting edge that described procapsid front end is fixedly mounted with is flush end cutting edge, or the top of cutting edge is that straight, bottom is tilting, or cutting edge is tilting, or cutting edge is stepped.
And the structure of described procapsid and back casing slip setting-in is: back casing front end is fixed with socket ring, this socket ring setting-in enters procapsid rear end.
And, between socket ring and procapsid, sealing ring is installed.
Advantage of the present utility model and beneficial effect are:
1, this development machine is divided into two sections, be respectively procapsid and back casing, sealing is installed in activity place between procapsid and back casing additional, in order to prevent that underground water and muddy water from invading in pipeline, cause operating personnel to construct, between forward and backward housing, install correction oil cylinder additional, the angle of correction is 2.5 degree left and right.
2, the Cutting Edge Design of this development machine is four kinds of forms, especially rectangle cutting edge, can effectively avoid choosing dress, can change according to the variation of soil property, has expanded the scope of application.
3, this development machine is installed respectively cutting edge on procapsid, mouth and grid fetch earth, especially designed grid, this grid is exactly the dividing plate that one or polylith level are installed in the larger driving cutting edge of diameter, when there is no grid, excavation surface is obviously extremely unsettled, has after grid, it and development machine can be loaded into one, comparatively robust like this, also it can be made dismountable, to strengthen the compliance of grid.
Accompanying drawing explanation
Fig. 1 is structure cross-sectional schematic of the present utility model;
Fig. 2 is the cutting edge structure schematic diagram of Fig. 1; Wherein Figure 21 is flush end cutting edge; The cutting edge top of Figure 22 is that straight, bottom is tilting; The cutting edge of Figure 23 is tilting; The cutting edge of Figure 24 is stepped.
The specific embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A hand pick formula pipe jacking tunnelling machine, comprises housing, cutting edge 2, fetches earth mouthfuls 3, correction oil cylinder 5 and Hydraulic Station 9, is fixedly mounted with cutting edge, fetches earth mouthful and correction oil cylinder, Hydraulic Station in housing.
Innovative point of the present utility model is:
1, described housing coaxially consists of procapsid 4 and back casing 8, back casing front end is fixed with socket ring 7, this socket ring setting-in enters the slip setting-in that procapsid rear end is realized procapsid and back casing thus, and sealing ring 6 is installed between socket ring and procapsid, in order to prevent that muddy water is from this intrusion; Correction oil cylinder is installed between the forward and backward housing in procapsid, Hydraulic Station is installed in back casing rear end, and concrete pipe or steel pipe that back casing will push up with first segment are connected, and this connection is rigidity, therefore, if jacking steel pipe is welded into one the front end of back casing and first segment steel pipe; If jacking concrete pipe, generally also adopts stay-bolt to fix back casing and first segment concrete pipe.
2, the cutting edge that described procapsid front end is fixedly mounted with has four kinds of forms, sees Fig. 2, and wherein Figure 21 is flush end cutting edge, and this cutting edge end face is vertical with tube hub; The top of the cutting edge of Figure 22 is that straight, bottom is tilting; The cutting edge of Figure 23 is tilting, and the most conventional; The cutting edge of Figure 24 is stair-stepping.
3, at the cutting edge of procapsid front end and fetch earth and be axially fixed with grid 1 between mouth, this grid is exactly the dividing plate that one or polylith level are installed in the larger driving cutting edge of diameter, when there is no grid, excavation surface is obviously extremely unsettled, have after grid, it and development machine can be loaded into one, like this comparatively robust, also it can be made dismountable, to strengthen the compliance of grid.
4, fetch earth mouth for rectangular cross section shape.
