Background technology
No-dig technique refers to utilize various drilling and tunneling equipments and technological means, by modes such as guiding, directional drillings on ground
In the case that table small part excavates, the construction technique of various underground utilities is laid, changed and repaired, will not be blocked the traffic,
Greenery patches will not be destroyed, vegetation, shop, hospital, the normal life of school and resident and order of work is not interfered with, solves tradition
Interference of the excavation construction to resident living, to traffic, environment, the destruction and harmful effect on surrounding building basis, therefore have
Higher social economic effect.Push bench process refers to that tunnel or underground piping railroad crossing, road, river or building etc. are various
A kind of tunneling formula construction method used during barrier.In construction, by power transmission top iron and guide rail, with being supported on foundation ditch
Pipe is pressed into soil layer by the hydraulic jack on back seat, while is excavated and transported the positive soil of pipe.When first segment pipe all pushes up
After underground layer, then by the followed continuation jacking of double section tube, a section is so saved into pipe and headed into, interface is performed, builds up culvert
Pipe.Push bench process is particularly suitable for building through into the culvert pipe below building, traffic lines or river, lake.Push pipe presses earth excavation
The difference of formula is divided into mechanical equivalent of light excavation jacking, extruding jacking, hydraulic excavation and hand excavation's jacking etc..But push pipe is pushing up
Will be by huge thrust during entering, but ordinary topping pipe bears limited pressure, it is easily cracked in process of deployment,
Cause to damage.
Utility model content
The utility model is for above-mentioned.
In order to achieve the above object, the technical solution adopted in the utility model is that the utility model provides a kind of new mixed
Native push pipe is coagulated, including by the integrally formed body of concreting and the interface and birdsmouth that are arranged on body both ends, it is special
Sign is：The body is provided at both ends with closed plate, and tubular body is provided with steel mesh reinforcement between two closed plate, described to insert
Interface inner diameter is identical with internal diameter of tube body, and the interface outer diameter is less than outer tube diameter, the interface inwall with it is outer
It is provided with equally distributed cylindrical reinforcing steel between wall, the cylindrical reinforcing steel and body axis parallel, outside the birdsmouth
Wall diameter is identical with body, and the birdsmouth inner diameter is engaged with interface outer diameter, the birdsmouth inwall with it is outer
Be evenly arranged with same interface inner structure size all identical cylindrical reinforcing steels between wall, and with body axis parallel, it is described
Body extexine is coated with anticorrosive coat, and drag reduction layer is provided with outside the anticorrosive coat.
Preferably, the anticorrosive coat is epoxy resin layer.
Preferably, the drag reduction layer is paraffin layer.
Compared with prior art, it is the advantages of the utility model with good effect,
The utility model be provided with body and interface and birdsmouth different shape but all with push pipe axis parallel
Reinforcing bar, push pipe is born bigger axial compressive force, and body is provided at both ends with closed plate, be not in top bad body
Phenomenon, and face is provided with anticorrosive coat outside push pipe, increases the service life, drag reduction layer is also coated with the outer surface of anticorrosive coat, profit
In the propulsion of push pipe.

Embodiment
It is below in conjunction with the accompanying drawings and real in order to be more clearly understood that above-mentioned purpose of the present utility model, feature and advantage
Example is applied to be described further the utility model.It should be noted that in the case where not conflicting, embodiments herein and reality
Applying the feature in example can be mutually combined.
Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality
New to implement using different from other modes described here, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, as depicted in figs. 1 and 2, the utility model provide a kind of new concrete push pipe, including by concrete
Pour integrally formed body 1 and be arranged on the interface 2 and birdsmouth 3 at the both ends of body 1, the diameter and pipe of the inwall of interface 2
The inner diameter of body 1 is identical, and the diameter of the outer wall of interface 2 is less than the external diameter of body 1, and the outer diameter of birdsmouth 3 and body 1
External diameter is identical, and inner diameter is engaged with the outer diameter of interface 2, and the interface 2 and birdsmouth 3 of two sections of identical push pipes are perfect
Docking.In order to solve push pipe be pressurized it is excessive cause body 1 to crack, as shown in figure 3, inventor is provided with tubular body
Steel mesh reinforcement 4, steel mesh reinforcement 4 surround body 1 one weeks, and the closed plate being provided at both ends with for fixing steel mesh reinforcement 4 of body 1
5, this closed plate 5 is slightly less than the diameter of body 1 but is held out against the both ends of steel mesh reinforcement 4 enough from circular steel plate, its diameter,
Meanwhile interface 2 and birdsmouth 3 are when mutually extruding, moreover it is possible to for protecting the both ends of body 1.When interface 2 heads into birdsmouth 3
When being engaged, interface 2 and birdsmouth 3, so shown in Fig. 4 and Fig. 5, in interface 2 and can also be accepted by large axial force
The inside of mouth 3 has all been uniformly distributed structure size all identicals and the cylindrical reinforcing steel 6 parallel with the axis of body 1, its
Number determines according to interface 2 with accepting the diameter of button 3, by the support of steel mesh reinforcement 4 and cylindrical reinforcing steel 6 to push pipe, increases
The big overall compressive resistance of push pipe, prevents push pipe in jack-in process because of the excessive cracked phenomenon of stress.As shown in fig. 6, it is
