Japan Tokyo International Engineering and Construction Machinery Exhibition(CSPI EXPO)It is the only engineering and construction machinery exhibition in Japan.,It is supported by many government agencies and industry associations.。The exhibition is a showcase of innovative products.、An important platform for deep technology development and latest trends。
In this exhibition,Many companies have demonstrated that based onTopcon LN-Innovative solutions for the 150 lofting robot。Among,AKTIO CorporationThe company's booth is particularly eye-catching.,Placed a large numberTopcon LN-150 equipment,Attracted the attention of many visitors.。AndAKTIO CorporationCompanyRSAfter in-depth exchanges with Mr. Ben of the Business Promotion Department,,It was learned that the company cleverly usedLN-150 as a survey method for small size tunnel pipe jacking construction,It shows its excellent technical strength and application prospects.。

About 75 years ago.,Pipe jacking method was first introduced in Japan.。This is a unique excavation technique.,By installing hydraulic jacks on the tunnel shaft wall,And pushes a push pipe connected to the rear of the Excavator to excavate.。When pushed a certain distance,Shorten the length of the Jack,Increase the length of the propulsion tube,Then push the Jack again,And so on,Until the excavation of the next shaft is completed。During the whole process,The long tube is pushed forward from behind.,These pipes can be used intact as sewer pipes after the excavation is completed.。
Compared with the shield method,The pipe jacking construction method does not need to carry out concrete spraying,Therefore, it has more advantages in cost.。In addition,Because the workers do not need to enter the narrow propulsion pipeline after excavation,,This method greatly improves the safety and efficiency of construction.。Nowadays,Pipe jacking has become the standard method in Japan for the construction of small tunnels between 10 cm and 3 m in diameter,It is widely used in the construction of water and sewage pipelines and infrastructure pipelines.。
However,Measure if the propulsion tube is advancing as designed,It's a very difficult thing.。The survey of the propulsion pipeline is usually carried out by several surveyors.,They need to crawl tens of meters in a narrow pipe with a diameter of only 80 centimeters.,Sometimes hundreds of meters long.。This is an extremely confined space.,People can't sit and stand in it.,Can only maintain a crawling position.。
Carry out measurement work in such a pipeline for a long time.,It is undoubtedly very arduous and dangerous.。This kind“Hard work”Leading many young workers to choose to leave the industry.,Thus exacerbating the ageing of the population.、The problem of labour shortage。What is more serious is that,As the measurement time increases,,There are often unnecessary delays during the construction period,Negative impact on the overall progress and benefits of the project。
In order to solve this problem,,AKTIO CorporationThe company has developed an automatic measurement system.“Pipe Shot”,This innovative product frees workers from the drudgery of pushing inside the pipeline.,The automation of measurement is realized.。Its appearance has aroused widespread concern in the industry.,As the latest pipe jacking measurementICTTechnology,It has revolutionized the industry.。
Pipe ShotThe core ofTopconManufacturedLN-150 lofting robot,AKTIOCustomized according to their own needs,And named“Pile Navi”。As the name suggests,Pile NavigatorIt was originally a measuring robot focusing on lofting.,ButPipe ShotIts application is extended to pipe jacking measurement.。The system is implemented by placing a plurality of 360-prism-equippedLN150 robots,Like a relay laser.,Simultaneous multipoint measurement is realized.,It greatly improves the efficiency and accuracy of measurement.。
In the process of grafting the propulsion tube,,LN-The 150 lofting robot is mounted directly inside the pipes。Once installedLN-The pusher tube of 150 starts to move forward,It is no longer necessary for surveyors to enter the tunnel for tedious crawling measurement.。Ven if there is a bend in the propulsion tube,It can also be pre-set.LN-150 placement position,Make sure that there is intervisibility between the two instrument,Thus ensuring the accuracy and efficiency of the measurement.。This innovative approach greatly reduces the workload of the surveyor,And that construction efficiency is improve.。
Mr. Ben introduced.,By usingPipe ShotSystem,Customers only need 1~Two people can complete the pipe jacking measurement in just 10 to 20 minutes.。One of the advantages of this method of measurement is that it requires no downtime,Can be measured directly during construction,Therefore adoptedPipe ShotThe whole construction period will be significantly shortened.。At present,There is no strict limit on the number of machines that can be connected.,But there is a limit to the working distance of propulsion from one shaft to the other.,Usually it's about 500 meters in most cases.。In the general case,Will use 10~15 setsLN-150 for joint measurement,To ensure the accuracy and efficiency of the measurement results.。
It is understood that,The system has been used in more than 60 projects.。At present,Congestion of urban ground traffic due to construction is common.,And the underground mall、An intricate network of railways and roads。So,Every year it becomes increasingly difficult to excavate water and sewage pipes from the ground for the installation of infrastructure pipes。The demand for efficient propulsion methods is expected to continue to increase,Pipe jacking construction is adopted(No excavation technology)The number of pipelines laid will also gradually increase.。
