Description
Technical field
The utility model relates to a kind of pipe structure, especially a kind of no-dig technique push pipe.
Background technique
In pipeline laying construction, generally there are two kinds of modes:
One is open heavy excavation mode, formation tube seat is all excavated by ground, be placed into after pipe is interconnected in tube seat, fill and lead up from newly spreading earth again, this pipe laying mode, pipeline does not bear the effect of pressure or top power, and the pipeline that is this digging mode is laid need not consider the restriction of top power, constructs comparatively simple and convenient.
Another kind of mode is owing to being subject to construction location environmental limit, such as buildings etc. can not adopt heavy excavation mode tubing, and adopt the mode pushed into by pipeline piecemeal in earth, namely dig a working pit in advance, when working pit operation, by depth location suitable in underground for one section one section, pipeline forward jacking pass, what the pipeline that this form of construction work uses had concrete top power bears restriction, the top power of bearing is little, cannot push in earth by pipeline, easily crack.
The pipeline of the pipeline that the paving mode that existing employing heads into adopts mainly concrete structure, but the ability that the pipeline of concrete structure bears top power is poor, heading in process of deployment, easily there is crackle in pipeline, also cannot accomplish timely detection after there is crackle, therefore bring larger trouble to construction.
Bearing the ability of axial top power in order to improve pipeline, a steel pipe socket in concrete duct, can be filled, but along with the increase of pipe diameter, the axially support power of steel pipe socket reduces, easily occur bending, and pipe diameter increases, the manufacture difficulty of steel pipe socket also increases.
Summary of the invention
The utility model solves existing push pipe, and to bear the ability of axial top power little, and the defect of crackle easily appears in push pipe in process heading into, provide a kind of no-dig technique push pipe, is lined with some axial steel pipes in push pipe tube wall, improves the ability that push pipe bears top power.
The utility model also solves existing push pipe inside and fills steel pipe socket, during making heavy caliber pipe-jacking, axially support power reduces, and easily occurs the defect of bending, provides a kind of no-dig technique push pipe, there is steel pipe support in tube wall, when making heavy caliber pipe-jacking, also can have larger axially support power.
The utility model solves the technological scheme that its technical problem adopts: a kind of no-dig technique push pipe, push pipe comprises inner and outer wall and the packing between inwall and outer wall, the two ends of push pipe arrange shut, some steel pipes are connected with between shut, the top power of the specification foundation engineering design of steel pipe requires to design, packing is filled in steel pipe outside, and the axis of steel pipe parallels with the axis of push pipe.The axis of steel pipe and push pipe axis being parallel, steel pipe can bear maximum axial force, can improve the axis top power of push pipe, there will not be the problem burst in top; Bear axial top power by steel pipe, the axis top power that packing is subject to is relatively little, thus can keep the integrity of packing and inwall and outer wall; Steel pipe along push pipe tube wall circumferentially, makes the quantity that bigbore push pipe increases steel pipe, or increases the sectional dimension of steel pipe, such as wall thickness, such as external diameter, just can increase substantially the axis top power of push pipe, and steel pipe can not increase the manufacture difficulty of push pipe; Can be strengthened the axis top power of push pipe by steel pipe, therefore adjust the specification of steel pipe, the parameters such as such as external diameter, wall thickness, material just can change the axis top power of push pipe.
As preferably, ringwise, the external diameter of shut is consistent with the external diameter of push pipe for shut.
As preferably, the inwall of push pipe extends to the inner peripheral surface of shut, and end and the shut of steel pipe fix.
As preferably, packing is the mixture of resin and silica sand; Or packing is concrete.
As preferably, steel pipe is evenly arranged in push pipe tube wall.According to the distribution heading into medium soil layer, steel pipe can be formed in tube wall different density shape distributions as required.
As preferably, steel pipe is arranged along push pipe tube wall central core; Or steel pipe relative tube wall deflection inwall is arranged.
As preferably, the shut of push pipe one end is that two pieces of semiclosed plates docking form, and two blocks of semiclosed plates are symmetrical, and two pieces of semiclosed plate ends docking are fixing forms complete shut.Shut can be that the little shut of polylith splices and combines and fixedly forms as required.
As preferably, end and the semiclosed plate of steel pipe fix formation supporting frame, and two supporting frames are combined to form integrated type push pipe axially support frame.
As preferably, the end portion place of two halves shut docking is fixed with steel pipe, and the axis of steel pipe is on the interface of two halves shut.
As preferably, inwall is the glass fibre reinforced plastics inwall that glass fibre becomes with resin compounded, and outer wall is the glass fibre reinforced plastics outer wall that glass fibre becomes with resin compounded.When pipeline is used for potable water, inwall adopts food level resin.Pipeline outer wall resin can also add the resin additive strengthening toughness, to strengthen the friction resistant ability of pipeline in jack-in process.
The beneficial effects of the utility model are: the axis of steel pipe and push pipe axis being parallel, and steel pipe can bear maximum axial force, can improve the axis top power of push pipe, there will not be the problem burst in top; Bear axial top power by steel pipe, the axis top power that packing is subject to is relatively little, thus can keep the integrity of packing and inwall and outer wall.
