As shown in fig. 1, fig. 2, fig. 4: the utility model provides a steel casing once pre-buried device, includes circular steel sheet 2 of installation on the civil engineering template, 2 central departments of circular steel sheet pass round steel 1, round steel 1 round steel 2 around open and to have the hole 3, the round steel 1 other end is mantle fiber 4, mantle fiber 4 on be provided with sleeve pipe shutoff mould 5.

The sleeve blocking mold 5 and the mantle fiber 4 are fastened through a nut 8.

As shown in fig. 3: the sleeve plugging mould 5 is of a stepped structure.

The preparation process comprises the following steps:

1. according to the model of the pipeline marked by the drawing, selecting a proper steel sleeve model, as shown in the following table:

selecting a meter for the type of the steel sleeve: unit: mm is

Serial number	1	2	3	4	5	6	7	8	9	10
											Pipe diameter	15	20	25	32	40	50	65	80	100	125
Pipe diameter of casing	25	32	40	50	65	80	100	125	125	150

2. A round steel plate 2 (the outer diameter of which is equal to that of the corresponding steel sleeve) and round steel 1 (phi 12).

3. Straight shank twist drill, welding electrode, iron red antirust paint, blue color and paint, round die and die holder, galvanized nut, self-tapping, and talc pen. Tool: the electric drill, the set square, the steel plate ruler, the steel tape, the compasses and the infrared level meter are held by hand.

4. The process comprises the following steps: manufacturing a mold (a sleeve fixing mold, a plugging mold and a positioning mold), coordinating civil engineering formwork matching, positioning a first-layer line drawing, fixing a sleeve, positioning and installing a second-layer sleeve, and protecting a finished product.

5. The process method comprises the following steps:

manufacturing a mould: and manufacturing a set of matched dies according to the steel sleeve of each type.

6. The mold is fixed to the sleeve: the steel sleeve is formed by welding a circular steel plate 2 with the inner diameter smaller than that of a steel sleeve by 2mm and round steel 1 (phi 12) with one end sheathed with threads, wherein the length L of the round steel 1 is 50mm longer than that of the steel sleeve with the corresponding model, and four round holes 3 (phi 5) are uniformly punched on the circular steel plate 2 to be used for fixing with a wood template;

7. the sleeve plugging die 5: a step equal to the wall thickness of the steel sleeve is cut at the edge of the circular steel plate 2 with the center of a phi 13 hole by using mechanical equipment, a circular steel plate 5 with a platform is manufactured and matched with a sleeve fixing mold for use, the upper opening of the sleeve is sealed and the sleeve is reliably fixed, and the outer diameter d1 of the circular steel plate 2 is equal to that of the steel sleeve 6 to be embedded.

8. A sleeve positioning die: similar to the plugging die, a step equal to the wall thickness of the steel sleeve is cut at the edge of the circular steel plate with a phi 3 hole at the center by using mechanical equipment, and a circular steel plate with a platform is manufactured and placed on the steel sleeve 6 for lower-layer positioning.

9. Firstly, before the template is erected, a pipeline well casing arrangement diagram is provided for a civil engineering, the position coordinates of the casing central line are marked, and the civil engineering is coordinated not to erect a batten within 100mm of the central line position, so that the positioning drilling is free of obstacles. And after the first-layer top plate template is erected, an inner wall line of the civil engineering discharge pipe shaft is required to be used as an accurate reference for sleeve pre-embedding. According to the pipeline well inner wall line provided by pipeline well arrangement technology intersection and civil engineering, tools such as a steel tape, a steel plate ruler, a set square, compasses and the like are used for measuring and releasing the central cross line of the sleeve, and the steel sleeve is positioned.
