[0034] There are multiple connecting pins 2. The connecting pins 2 are detachably inserted into the first locking hole a of the lower barrel section 1 and the second locking hole c of the upper barrel section 1.

[0035] In this embodiment, two adjacent cylinder sections are connected together via four connecting pins.

[0036] See also Figure 4 As shown, the support pipe 3 is connected to the lower end of the top barrel section 1. The support rod is arranged along the radial direction of the top barrel section.

After two adjacent cylinder sections are plugged together, the rubber strip is padded between the lower end surface of the upper cylinder section and the upper end surface of the lower cylinder section. The rubber strip has a sealing and plugging function.

[0040] The present invention provides a construction method of a segmented assembling type shaped casing, comprising the following steps:

[0041] S1. Connect the top cylinder section 1 to the pile construction equipment.

[0042] S2. Align the anti-deflection protrusion 12 on the plug connector 11 of a cylinder segment 1 with the notch d of the top cylinder segment 1 and insert it into the notch d, so that the plug connector 11 of a cylinder segment 1 is inserted into the socket expansion hole b of the top cylinder segment 1 so that the first locking hole a of the cylinder segment 1 is aligned with the second locking hole c of the top cylinder segment 1.

[0043] S3. Push the toggle rod 21 toward the top tube section along the length direction of the slide groove of the support tube 3, so that a connecting pin 2 is detachably inserted into the first locking hole a of a tube section 1 and the second locking hole c of the top tube section 1.

[0044] S4. When extending the casing, push the toggle rod 21 in the reverse direction to make a connecting pin 2 retreat into the second locking hole c of the top barrel section 1, set the other barrel section 1 between the first barrel section 1 and the top barrel section 1, and then insert the plug joint 11 of the other barrel section 1 into the socket hole of the top barrel section 1, and sleeve the socket expansion hole b of the other barrel section 1 on the plug joint 11 of the first barrel section 1, and lock the two adjacent barrel sections 1 with the connecting pin 2. Conversely, when lifting the casing, remove the barrel section 1 below the top barrel section 1 section by section to facilitate filling.

[0045] When the upper barrel section and the lower barrel section in the segmented and assembleable fixed casing of the present invention are connected, the lower end of the upper barrel section is sleeved on the outside of the plug joint of the lower barrel section, and the notch at the lower end of the upper barrel section corresponds to the anti-deflection protrusion of the lower barrel section to ensure upper and lower alignment. After the nesting is completed, the inner wall and the outer wall of the casing are flush, and the second locking hole is connected to the first locking hole by a connecting pin shaft, and a rubber strip is set at the connection position to ensure airtightness.

[0046] After the top barrel section of the segmented and assembled fixed casing of the present invention is fixed to the pile construction equipment, the top barrel section is aligned with the barrel section to ensure that the notch corresponds to the anti-deviation protrusion and is aligned up and down. By rotating the toggle rod, the connecting pin is inserted through the support pipe into the first lock hole of the barrel section to play a fixing role. When extending the casing, the socket expansion hole at the lower end of the barrel section needs to be nested on the plug joint at the upper end of the lower pipe section, the notch is aligned with the anti-deviation protrusion, and after the second lock hole is aligned with the first lock hole, the connecting pin is rotated to fix the connecting barrel section and the barrel section. Reciprocating operation is performed to meet the needs of extending the casing.

The use of this segmented casing can effectively reduce the operating height of the casing installation machinery. For example, the vibro-impacted crushed stone pile construction requires filling in batches, and the segmented casing can be lifted and removed in sections according to the filling requirements. It is easy to operate, improves the operability of the construction process, and thus ensures the construction efficiency.
