長谷川建設工業 List of Products and Services

Hasegawa Construction Industry Co., Ltd. has been engaged in both large and small thrust construction projects for over 20 years. Here are some examples of the projects carried out by Hasegawa Construction Industry. One example is a project in Oohara, Isumi City, where we crossed a national highway. We created a launch shaft with a diameter of φ2.0m within the application site and thrust to the main pipe on the opposite side of the road. The thrust construction involved pushing a lead pipe (temporary pipe) from the launch shaft towards the main pipe, and then pulling in a φ50A steel pipe from the main pipe side. The construction from the creation of the launch shaft to the thrust work was completed in one day. Additionally, in Karabe, Narita City, we thrust a lead pipe to the main pipe located on the opposite side of the application site, which has four lanes (five lanes including the right turn lane), and we pushed a φ100mm steel casing pipe from the launch shaft. The thrust length was 22.3m. As such, we can construct by building the launch shaft within the application site without excavating on public roads. 【Proposal from Hasegawa Construction Industry】 - After thrusting a φ65A steel pipe, we completed the installation of a φ50A steel casing pipe. - Connection with continuous water drilling by waterworks contractors. - Installation of the main pipe inside the casing pipe. → It is also possible to directly pull in poly pipes or stainless steel pipes without using a casing pipe.
