Technical Field

The invention belongs to a manhole supporting device, and particularly relates to a detachable hollow curved surface body framework manhole supporting device.

Background

In the investigation of loess areas, well exploration is the most important exploration means, along with the implementation of collapsible loess area building standard (GB 50025-2018), the depth requirement on the exploratory well is further increased, and along with the increase of the exploratory well depth, the risk of collapse is further increased, the exploratory well needs to be supported, the supporting facility has the characteristics of stability, reliability, convenience in transportation, rapidness in installation and the like, the existing supporting means is mainly that an underground wood plate is supported, the installation speed is low, and the repeated use cannot be realized, so that a novel supporting device is urgently needed.

Disclosure of Invention

In order to solve the problems that the existing support is slow in installation speed and cannot be used repeatedly, the invention provides the detachable hollow curved surface body framework manhole support device. The device is stable and reliable, quick to install and disassemble, reusable and convenient to transport.

The technical scheme adopted by the invention is as follows:

the utility model provides a hollow curved surface body skeleton manhole supporting device of detachable, is at least including parcel area and hollow curved surface body skeleton, hollow curved surface body skeleton be a plurality of, a plurality of hollow curved surface body skeletons are fixed in proper order on the parcel area, the parcel area is rolled up and is hollow cylinder form, a plurality of hollow curved surface body skeleton be located the parcel in-band.

The hollow curved surface body frameworks are sequentially fixed on the wrapping belt through bolts.

The bolt is an M10 bolt.

The wrapping belt comprises nylon magic cards, wrapping belt bolt holes, lifting lugs and a wrapping belt main body, the nylon magic cards are arranged at the left end and the right end of the wrapping belt main body, the two lifting lugs are symmetrically arranged at the upper end of the wrapping belt main body, and a plurality of wrapping belt bolt holes are distributed in the wrapping belt main body.

The outer side surface of each hollow curved surface body framework is provided with an outer bolt hole, and the outer bolt hole corresponds to a wrapping belt bolt hole on a wrapping belt; the curvature of the inner side of the hollow curved surface body framework is 300R, and the curvature of the outer side of the hollow curved surface body framework is 400R.

The hollow curved surface body frameworks are 12, and 12 hollow curved surface body frameworks are fixed on the wrapping belt through bolts and bound by the wrapping belt to form a cylinder.

The hollow curved surface body framework adopts 5052 aluminum alloy.

Lug and parcel area main part all adopt 300D oxford to make, the lug hole inlay the becket.

The invention has the beneficial effects that:

the invention is used in the exploratory well, the hollow curved surface body framework is fastened by the wrapping belt to form a hollow cylinder structure, and then the hollow cylinder structure is placed in the exploratory well, thereby achieving the purposes of preventing the exploratory well from collapsing and protecting the safety of operating personnel in the well. The device has the advantages of stability, reliability, quick assembly and disassembly, repeated use and convenient transportation.

The invention will be further explained with reference to the drawings.
