DESCRIPTION ADJUSTABLE SUPPORTING DEVICE FOR GEOTECHNICAL ENGINEERING FIELD OF THE INVENTION

The invention relates to the field of construction, in particular to an adjustable supporting

device for geotechnical engineering.

BACKGROUND OF THE INVENTION

As a structural system, foundation pit support should meet the requirements of stability

and deformation, that is, the requirements of the two limit states mentioned in the general

specification, namely the bearing capacity limit state and the normal service limit state.

The so-called bearing capacity limit state for foundation pit support is the destruction, tipping,

sliding of the support structure or damage to the surrounding environment, resulting in a

relatively large range of instability. The general design requirements do not allow this limit

state of the supporting structure.

The normal service limit state refers to the deformation of the supporting structure or the

deformation of the surrounding soil caused by excavation, which affects normal use, but does

not cause structural instability. Therefore, the foundation pit support design must have a

sufficient safety factor relative to the bearing capacity limit state, so as not to cause the

supporting device to lose stability, and under the condition of ensuring that there is no

instability, the displacement must be controlled so as not to affect the safe use of the

surrounding buildings. Therefore, as a design calculation theory, not only the stability of the

supporting structure should be calculated, but also its deformation should be calculated, and

the deformation should be controlled within a certain range according to the surrounding

environmental conditions.

However, the traditional supporting devices do not allow for effective angle adjustment,

and even if the reserved amount is calculated before erecting the device, the supporting force

of the device is not sufficient.

SUMMARY OF THE INVENTION

The technical problem to be solved by the invention is to provide an adjustable

DESCRIPTION supporting device for the above problems.

In order to solve the above technical problems, the technical solution provided by the

present invention is: an adjustable supporting device for geotechnical engineering, which

comprises a foundation; a supporting wall is hinged on the foundation, fasteners are arranged

on both sides of the supporting wall, and the fasteners on both sides can be connected together;

one side of the supporting wall is fixedly connected with hinge joints, hydraulic rods are

hinged on the hinge joints, hydraulic cylinders are attached to the hydraulic rods, and cylinder

bases are hinged on the bottom of the hydraulic cylinders.

Compared with the prior art, the invention has the advantages that it can avoid the

traditional support structure being single, and the angle can be changed according to the needs

of geotechnical engineering; the supporting device is locked by the adjacent fixing method,

and the supporting force is provided by hydraulic pressure. The structure is simple, easy to

use, and has a good market prospect.

As an improvement, the foundation and the cylinder bases are provided with cones at the

bottom, which is good for driving the foundation of the supporting device into the rock or soil

to form a fixation.

As an improvement, the articulated joint between the foundation and the supporting wall

is a hydraulic joint, which also provides a certain support force to the supporting wall,

forming a double insurance.

As an improvement, the number of the hydraulic cylinders, hydraulic rods, hinge joints

and cylinder bases is two, which are separately arranged on both sides of the supporting wall

to form a good supporting structure.

As an improvement, two hydraulic cylinders and the hydraulic joint are connected to a

hydraulic press, the single hydraulic press is better controlled and easier to use, and later the

hydraulic presses of all supporting walls can be connected together for computer control.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following is a further detailed description of the invention in conjunction with the

accompanying drawings.

In the actual implementation of the invention, an adjustable supporting device for

geotechnical engineering comprises a foundation 1; a supporting wall 2 is hinged on the

foundation 1, fasteners 3 are arranged on both sides of the supporting wall 2, and the fasteners

3 on both sides can be connected together; one side of the supporting wall 2 is fixedly

connected with hinge joints 4, hydraulic rods 5 are hinged on the hinge joints 4, hydraulic

cylinders 6 are attached to the hydraulic rods 5, and cylinder bases 7 are hinged on the bottom

of the hydraulic cylinders 6.

As an improvement, the foundation 1 and the cylinder bases 7 are provided with cones 8

at the bottom, which is good for driving the foundation 1 of the supporting device into the

rock or soil to form a fixation.

As an improvement, the articulated joint between the foundation 1 and the supporting

wall 2 is a hydraulic joint 9, which also provides a certain support force to the supporting wall

2, forming a double insurance.

As an improvement, the number of the hydraulic cylinders 6, hydraulic rods 5, hinge

joints 4 and cylinder bases 7 is two, which are separately arranged on both sides of the

supporting wall 2 to form a good supporting structure.

As an improvement, two hydraulic cylinders 6 and the hydraulic joint 9 are connected to

a hydraulic press 10, the single hydraulic press 10 is better controlled and easier to use, and

later the hydraulic presses 10 of all supporting walls 2 can be connected together for computer

control.

The working principle of the invention: the supporting walls are completely connected

together by means of fasteners of adjacent supporting walls, which can effectively prevent the

inadequate supporting capacity of individual supporting walls, and the overall support force is

DESCRIPTION provided by hydraulic means, which can fully afford the pressure brought by the rock and soil

and is very convenient.

In the present invention, unless otherwise clearly specified and limited, the first feature

"'on" or "under" the second feature may include direct contact between the first and second

features, or may include contact between the first and second features not directly, but through

other features between them. Moreover, the first feature is "above", "over", and "in the upper

of' the second feature can be that the first feature is directly above or obliquely above the

second feature, or simply indicating that the first feature is horizontally higher than the second

feature. The first feature is "below", "under", and "in the lower of' the second feature can be

that the first feature is directly below or obliquely below the second feature, or simply

indicating that the first feature is horizontally lower than the second feature.
