Abstract
The invention provides trenchless pipeline replace equipment with a double-ring cutter and a method thereof. The equipment comprises a shield mechanism provided with an outer ring cutter and an inner ring cutter, a slip casting mechanism and a traction mechanism. The using method of the equipment comprises the following steps: rapidly rotating the cutter at the front end of the shield mechanism under the action of a driving mechanism, rotary-cutting and expanding the stratum on the periphery of the old pipeline wall by the outer ring cutter, cutting the old pipeline wall forward by the hopper-shaped inner ring cutter, and meanwhile squeezing inwards to enable the pipe wall to be crushed, pulling the shield mechanism forward unceasingly to break down the old pipeline wall by a tractor, and meanwhile laying new pipelines connected with the back part of the shield mechanism forwards, unceasingly injecting circulating mud by the slip casting mechanism, lubricating the cutters, and bringing the scraps produced after cutting the old pipeline wall out the pipelines. The equipment has the advantages that the underground pipeline replacement can be finished under the trenchless condition; the efficiency is high; and the influence on the periphery is small.
Description
Technical field
The disclosure relates to a kind of more exchange device and using method thereof of non-excavation pipeline with dicyclo cutter, belongs to trenchless technology field.
Background technique
Along with the continuous quickening of urbanization process, in urban underground space, pipeline is increasing, thereby produces the needs that old pipeline is changed.These pipelines that need to change are generally laid on the urban district populous, business is bustling, are often filling other some pipelines at tube circumference, also ride pressing building or below road on pipeline.Excavation construction will cause the breaking-up in traffic congestion, greenery patches and gardens, also may cause breaking-up to underground communal facilitys such as some other pipeline, cables.
Along with the development of trenchless technology and perfect, addressing this problem the best way is exactly the non-excavation pipeline replacing technology of giving birth to therefrom.Because having the advantages such as construction site is little, construction is simple, cost is lower, this technology is widely applied.The non-excavation of old pipeline is changed to be actually at the original position place of old pipeline and is changed, and, taking the old pipe that will change as guide, in the broken old pipe of special-purpose machines and tools, people is drawn in or pushed up to identical diameter or slightly large new pipe and completes replacing operation to replace old pipe.Main non-excavation replacing technology has booster method, eats Guan Fa etc.
Wherein, eating pipe method is to change application and the improvement in field at pipeline in micro-tunneling pipe laying engineering method.This engineering method adopts smear metal cutter that old pipeline to be changed is pulverized.The smear metal cutter of particular design can " be eaten " any obstacle falling in pipeline and soil layer and soil layer.The new pipeline that pipeline chip connects below by cutting head is discharged to earth's surface.The rear portion that new pipeline is connected to excavator is brought into.
Fig. 1 is the existing more schematic diagram of exchange device of pipe method pipeline of eating.As shown in Figure 1, existingly eat shield machine structure that pipe method uses and generally comprise a smear metal 91 and a shield structure body 92.In smear metal 91, smear metal tooth is housed, is used for the old pipeline 4 of smear metal.Smear metal head is placed in the edge of shield structure body 92, and soil layer smear metal is arrived the needed diameter of new pipeline is installed.In smear metal head, be conical heading end 93, when work, be inserted into the old pipeline 4 that will replace, can reduce like this wearing and tearing of smear metal tooth to tension force of pipeline.But, because chip is pushed to outward edge along conical heading end, be unfavorable for the discharge of pipeline chip, easily cause chip to be blocked in the front end of shield machine structure, reduce the efficiency of constructing.
