Abstract

The utility model discloses a geotechnological check room suitable for bolt formula is connected, geotechnological check room comprises two liang of adjacent geotechnological check room sheets of bolt connection, its characterized in that: the bolt is connected with the geocell sheet through a connecting hole in the geocell sheet, and the connecting hole in the geocell sheet is oblong or circular. The utility model discloses disperseed the stress that the connecting hole receives, strengthened the intensity of geotechnological check room, the mode that sets up of wash port has both maintained the required area of drainage function, again the maximum strength reduced vertical tensile loss.

Description

Geocell suitable for bolt type connection

Technical Field

The utility model relates to a geotechnique's building material field specifically is a geotechnological check room suitable for bolt formula is connected.

Background

Geotechnological check room is the three-dimensional netted check room structure of constituteing through the different connected mode by a plurality of geotechnological check room sheets, and its connected mode is various, commonly uses geotechnological check room sheet to punch a hole, and the use is mostly towards the quad slit now, then two liang of stacks of sheet, connects in the bolt patchhole. This kind of connected mode, when the tensile strength of test geotechnological check room, can be with two geotechnological check rooms tensile to different directions respectively, at this moment, the bolt can be partial to one side in punching a hole, and the stress of bolt all concentrates on the angle of square punching a hole, and the sheet can not bear and can consequently tear, because the characteristic of sheet, in case tear, tensile ability is nearly zero to make geotechnological check room's tensile ability reduce rapidly.

In addition, when present geotechnological check room is used for the bank protection, because the characteristic of sheet, do not have the drainage function, if simply punch a hole and can cause geotechnological check room longitudinal tension to lose its original function.

Disclosure of Invention

The utility model discloses to above weak point, provide a geotechnological check room suitable for bolt formula is connected, the utility model discloses a set up when the mode makes geotechnological check room use, changed the effect point of bolt stress, prevented tearing of sheet for during the bank protection, increased geotechnological check room's drainage function.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a geotechnological check room suitable for bolt formula is connected, geotechnological check room comprises two liang of adjacent geotechnological check room sheets of bolt connection, the bolt passes through the connecting hole on the geotechnological check room sheet and connects it, the connecting hole on the geotechnological check room sheet sets up to oblong or circular.

Oblong drain holes are uniformly distributed on the geocell sheets around the geocell.

The direction of the long edge of the drain hole is vertical to the height direction of the geocell.

The adjacent rows of the drainage holes are staggered.

After the punched hole is arranged to be oblong or circular, when the sheet is used, even if the bolt is extruded to one side under the action of external force, the stress of the bolt on the punched hole is not concentrated on a certain point any more but is uniformly dispersed on the surface, so that the stress of each point is reduced, and the sheet cannot be torn due to incapability of bearing.

Punching a hole on geotechnique's check room sheet, can satisfy the needs that are used for the drainage when the bank protection, set up the wash port into oblong shape, furthest remains tensile strength when realizing the drainage function, reduces vertical tensile loss.

Drawings

Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention;

fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.

Detailed Description

The invention is described in detail below with reference to the following figures and specific embodiments: this patent the oblong shape is the shape that forms behind the rectangle four corners fillet.

Example 1

As shown in fig. 1, the geocell suitable for bolt type connection is composed of bolt connecting two adjacent geocell sheets 3, the bolt connects the adjacent geocell sheets through connecting holes 1 on the geocell sheets, and the connecting holes 1 on the geocell sheets 3 are arranged to be oblong. Drain holes 2 are uniformly distributed on the geocell sheets around the geocell. The direction of the long edge of the drain hole 2 is vertical to the height direction of the geocell. The drainage holes 2 are arranged in a staggered mode between adjacent rows.

The utility model discloses disperseed the stress that the connecting hole receives, strengthened the intensity of geotechnological check room, the mode that sets up of wash port has both maintained the required area of drainage function, again the maximum strength reduced vertical tensile loss.

Example 2

As shown in fig. 2, the geocell suitable for bolt type connection is composed of bolt connecting two adjacent geocell sheets 3, the bolt connects the adjacent geocell sheets through connecting holes 1 on the geocell sheets, and the connecting holes 1 on the geocell sheets 3 are circular. Drain holes 2 are uniformly distributed on the geocell sheets around the geocell. The direction of the long edge of the drain hole 2 is vertical to the height direction of the geocell. The drainage holes 2 are arranged in a staggered mode between adjacent rows.
