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 driver, 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 non-excavation pipeline with dicyclo cutter more exchange device and using method thereof, belongs to the trenchless technology field.
Background technique
Along with the continuous quickening of urbanization process, pipeline is increasing in the urban underground space, thereby produces the needs that old pipeline is changed.That these pipelines that need change generally are laid on is populous, commercial bustling urban district, is often filling other some pipelines at tube circumference, also rides pressing building or be in below the 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 continuous 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 advantages such as the construction site is little, construction is simple, cost is lower, this technology obtained extensive use.The non-excavation of old pipeline is changed to be actually at the original position place of old pipeline and is changed, and is guide with the old pipe that will change namely, and identical or big slightly new pipe is drawn in or pushed up the people and finishes the replacing operation to replace old pipe with diameter in the broken old pipe of special-purpose machines and tools.Main non-excavation replacing technology has the booster method, eats Guan Fa etc.
Wherein, eating the pipe method is to change application and the improvement in field at pipeline in miniature tunnel pipelayer's method.This worker's method adopts the smear metal cutter that old pipeline to be changed is pulverized.The smear metal cutter of particular design can " be eaten " and fall pipeline and soil layer and the interior any obstacle of soil layer.The pipeline chip is discharged to the face of land by the new pipeline that cutting head connects later.The rear portion that new pipeline is connected excavator is brought into.
Fig. 1 is the existing more schematic representation of exchange device of pipe method pipeline of eating.As shown in Figure 1, existingly eat the employed shield machine structure of pipe method and generally comprise a smear metal 91 and shield structure bodies 92.In the smear metal 91 the smear metal tooth is housed, is used for the old pipeline 4 of smear metal.The smear metal head is placed in the edge of shield structure body 92, the soil layer smear metal is arrived new pipeline necessary diameter is installed.Be conical heading end 93 in the smear metal head, be inserted into the old pipeline 4 that to replace during work, can reduce the wearing and tearing of smear metal tooth like this for tension force of pipeline.But, because chip is pushed to outward edge along conical heading end, be unfavorable for the discharge of pipeline chip, cause chip to be blocked in the front end of shield machine structure easily, reduced the efficient of constructing.
