であった。しかしながらこの施工法に↓ると。Conventionally, when constructing a caisson using an earth and sand center, the earth and sand center is first created using embankment on the ground at the location where the construction is to be performed, then the Ml frame of the caisson is formed on this earth and sand center, and after Initial excavation is performed by input using the shaft hole of this frame, a working hole is created in the earth and sand center, and the 10 excavating machines that are lowered through the shaft hole are assembled in this working hole, and after assembly, the earth and sand center is machined. This involved excavating and constructing a work room below the first frame. However, with this construction method.
初期掘削としての作業孔を入力に工９掘削して形成する
ので、機械掘削に至るまでに入手と時間がかかる問題が
あった。Since the initial excavation hole is formed by drilling 9 drills as input, there is a problem in that it takes time to obtain materials before mechanical excavation.
本発明の目的は作業孔の施工作業をｉＫｊ累化して、機
械掘削に至るまでの作業の省力化と迅速化とを図ること
にある。An object of the present invention is to accumulate the work of constructing a working hole to save labor and speed up the work up to mechanical excavation.

業室を施工するものである。This buried support has a size and type that allows it to be taken out of the first body through the shaft hole. The construction method is to first construct the first body of the caisson on the earth and sand center, then use the shaft hole of this first body to pull up the embedded support to the upper blade of the heavy body. A hole is created in the earth and sand center by pulling up, and this hole is used as a working hole. After assembling the llj excavation machine in this hole, excavation such as mechanical excavation of the earth and sand center is carried out, and work is performed on the first fan F force. The purpose is to construct a room.

つ積上げた状態で埋設しである。In Figure 1.2, the sediment center l is located at a height of 2 above the ground.
It was created using an embankment of m. Inside this earth and sand center is the first frame 2 of the caisson, which is supported on its outer surface.
M feet of sand-filled mounds 3 as temporary buried supports are embedded in advance in positions facing the shaft holes 2a and 2b. f
In other words, in a position facing the shaft hole 2a used by the cultivation workers, nine cans 3 containing sand are buried in a stacked state, five at the bottom and four at the top. At a position facing the shaft hole 2b used as a conveyance path for mechanical parts, etc., 20 sand canisters 3 are buried, stacked one on top of the other in each of the upper F tiers.

らなる吊シ紐５が取り付けＣある。The sand canister 3 has a height of about 900+ as shown in Figure 3.4.
It is a drum-shaped container with an outer diameter of approximately 550 mm, and is filled with sand. On the outer surface of the sand can, reinforcing bars 4 and 4a are welded vertically and horizontally, and the vertical reinforcing bars 4 and 9 are somewhat thicker. It is useful. A hanging cord 5 made of wire is attached to the upper end of the sand can 3.

第１鴫体２のＦ方に作業室８を形成する。Then, as shown in Fig. 1, the formwork is completely assembled, reinforcement is placed, and a comfleet track is cast on the earth and sand center l to form the first frame 2 of the caisson. Using the iron and the shaft holes 2a and 2b provided in the first body, the sand cans 3 are sequentially taken out of the first body by a crane. first 1
~ When removing the two cans, if you use a jet in the gap between the city and the can to remove the dirt stuck in the gap, the lifting will be smooth. When all the sand cans 3 are pulled up, two working holes 1a and 1b are formed in the sand center 1 at positions facing the shaft holes 2a and 2b, respectively, as shown in FIG. Excavate and level the ground in and around each work hole as required, and then drill one shaft hole 2b.
All the parts of the excavating machine are lowered into the working hole lb, and after the machine is assembled, the excavating machine is moved to the excavation machine. 1. A working chamber 8 is formed on the F side of the body 2.

Although it is inexpensive and allows quick stacking and removal work, it is not necessarily limited to those containing sand; earth, crushed stone, etc. may be used instead of sand. The number of cans can also be selected depending on the quotient of the sediment center, the size of the first body of the caisson, etc. ///
JRA, the temporary burial support is not something that can be stored in a can.
It may be made of sand or the like.

の盛土用土砂を節約できる。As explained above, if the present invention is used, there is no need to construct a working hole by input drilling as in the conventional method, so the construction work of this working hole can be simplified, and therefore mechanical excavation using the working hole can be performed. It is possible to save labor and speed up the work until completion. Furthermore, it is possible to save earth and sand for embankment in an amount equivalent to the volume of the temporary burial support.
