Abstract

PURPOSE:To exchange a small section pipe to a new large section pipe without influence to its environment by constructing a trisection pipe construction segment to place an established pipe at the inside thereof and connecting them each other like a ring. CONSTITUTION:One of trisection pipe construction segments 2 is installed below an established pipe 1. The remained two pipe construction segments 2 are connected to both connecting ends in a ring direction like a ring to place the established pipe 1 inside the pipe. Ring like connecting works like this are performed in turn, ring like three pipe construction segments 2 are connected to connecting ends in a pipe extending direction to construct a continuous united pipe having the established segment 1 therein, which builds a new concrete pipe 3. Later, the established pipe 1 therein is broken and removed to complete the exchanging work.

According to the method of the present invention, while supporting the existing pipe, excavation is made around the existing pipe, and the pipe forming segment, which is divided into three equal parts for a new pipe structure, is formed into a ring shape with the existing pipe inside the pipe. Connect to. In addition, a new pipe will be laid by connecting these three ring-shaped pipe constituent segments in the pipe extension direction and incorporating the existing pipe into a continuous, integrated pipe.

Since the new large-section pipe is installed by taking the existing pipe inside, the construction work can be carried out while the existing pipe is used without causing any problems. Also, there is no need for new space for newly installed large-section pipes (
Since the pipe is laid at the location where existing pipes are laid, it does not cause damage or other problems to surrounding buried objects.

First, the area around the existing pipe 1 (a small-section pipe for sewage that has already been laid) is excavated to a certain length using the usual cut-and-cover method, and the existing pipe 1 is suspended from the ground surface. (See FIG. 1) One pipe segment 2, which is divided into three equal parts, is installed below the existing pipe 1.

Next, while sequentially performing such a ring-shaped connection work,
A new pipe 3 is laid by connecting three ring-shaped pipe constituent segments 2 to the connecting end face in the pipe extending direction and incorporating the existing pipe 1 into a continuous integral pipe.

Then, after assembling a concrete pipe consisting of pipe constituent segments 2 divided into three equal parts on the outside of the pipe, the existing pipe 1 inside is demolished and removed, and a new pipe 3 with a large cross section is assembled.
Pour water into it.

Moreover, since the construction is divided into three parts, one segment 2 can be inserted at the bottom, and the two upper segments 2 can be used to close from both sides, so the construction is very easy. Moreover, since this pipe 3 is an internal static structure, it can stand on its own and is stable as long as the joint does not come off. Therefore, if a water-stop sealing material (not shown) is effectively used, the circular integral pipe ( It is in no way inferior to the conventionally used Huyum tube.

Each segment 2 is fastened on the outside of the pipe 3, but with the straight bolt method, the notch recess 4 (blockout) is large and the fitting 5 is also large, so corrosion is economically undesirable. , use a small drop bolt 6 of the fitting (see Figures 4 and 5). Of course, various types of joints are also possible.
