Abstract
The utility model provides a limiting plate that a hydraulic pressure limiting plate for steel strand stretching relates to the steel strand stretching in the excavation supporting system. The utility model discloses separating support point in traditional limiting plate and spacing position, through increase hydraulic means at support point, controlling the distance between stopper body and the ground tackle in a flexible way, and then elasticity degree between control clamping piece and the ground tackle, avoided the steel strand stretching in -process to have each other decreasing that great pressure leads to between because of clamping piece and steel strand wires, simultaneously when the stretching force reaches locking value, compress tightly clamping piece and ground tackle through hydraulic means, the displacement of control clamping piece reduces to lock stress loss.
Description
[technical field]:
This utility model relates to the limiting plate of steel strand tension in Geotechnical Engineering field.
[background technology]:
The steel strand tension limiting plate used in foundation pit supporting system at present is usually the resistance to compression ferrum of given shape
Plate, it can be subdivided into support zone and spacing position, and in stretching process, support zone stress drives the reach of limiting section position,
Spacing position then utilizes its concave surface to control the spacing between intermediate plate and anchorage, but by the shadow of the Conventional limit plate further groove degree of depth
Ringing, in stretching process, anchorage forms extruding to intermediate plate, makes, often in compaction between intermediate plate and steel strand wires, then to lead
Cause to there will be between intermediate plate and steel strand wires in various degree is impaired；And there is the phenomenon moved outside stress in intermediate plate when locking,
Bigger stress loss occurs.
[utility model content]:
The purpose of this utility model is to provide a kind of structure novel, can well control tension stress simultaneously and damage
The steel strand tension limiting plate lost.
In order to solve Conventional limit plate at stretching process folder when occurring that intermediate plate and steel strand wires damage mutually and lock
The phenomenon that off-chip is moved, the technical solution adopted in the utility model is: a kind of hydraulic stop plate for steel strand tension, bag
Containing stretch-draw jack and steel strand wires, it is characterised in that: steel strand wires one end is anchored in anchor hole by stretching into grouting soil,
The other end is outside Rock And Soil, and interface uses anchorage to be fixed with anchor plate；Steel strand wires outside Rock And Soil sequentially pass through anchor
Backing plate, anchorage, intermediate plate, bearing plate, hydraulic means and stretch-draw jack, then use moveable anchor to be fixed, hydraulic pressure
Device is connected with hydraulic pump by high-pressure oil pipe, and hydraulic pump arranges relief valve and digital display manometer.Further, liquid is also included
The supporter of pressure device both sides.
Described hydraulic stop plate, it is characterised in that: when stretch-draw jack is not up to tensioning lock definite value, hold
Intermediate plate between pressing plate and anchorage is in relaxed state, it is to avoid the stress between intermediate plate and steel strand wires is damaged mutually；When stretching force reaches
After lock value, by hydraulic means, intermediate plate is compressed with anchorage, control intermediate plate displacement, reduce locking stress loss.
[accompanying drawing explanation]:
Fig. 1 is generalized section of the present utility model.
In figure:
1, stretch-draw jack 2, steel strand wires
3, hydraulic means 4, supporter
5, Rock And Soil 6, anchor hole
7, moveable anchor 8, hydraulic pump
9, high-pressure oil pipe 10, bearing plate
11, intermediate plate 12, anchorage
13, anchor plate
[detailed description of the invention]:
In conjunction with accompanying drawing 1, implementation process of the present utility model is illustrated.
A kind of hydraulic stop plate for steel strand tension, comprises stretch-draw jack and steel strand wires, steel strand wires one
Hold and be anchored in anchor hole 6 by stretching into grouting soil, the other end outside Rock And Soil, through anchor plate 13, anchorage 12,
Intermediate plate 11, bearing plate 10, hydraulic means 3 and stretch-draw jack 1, use moveable anchor 7 to be fixed, hydraulic means 3
Being connected with hydraulic pump 8 by high-pressure oil pipe 9, hydraulic pump 8 arranges relief valve and digital display manometer.
Work process is: first uses anchorage, anchor plate to pre-fix steel strand wires, by moveable anchor, adopts
With stretch-draw jack, steel strand wires are carried out stretch-draw, after stretching force reaches lock value, by hydraulic pump, hydraulic means is carried out
Pressurization, and then intermediate plate is compressed with anchorage.Then stretch-draw jack, hydraulic means are carried out pressure release, and then remove very heavy
Top, hydraulic stop plate, so far steel strand tension is complete.
Described hydraulic stop plate, it is characterised in that: when stretch-draw jack is not up to tensioning lock definite value, pressure-bearing
Intermediate plate between plate and anchorage is in relaxed state, it is to avoid the stress between intermediate plate and steel strand wires is damaged mutually；When stretching force reaches
After lock value, by hydraulic means, intermediate plate is compressed with anchorage, control intermediate plate displacement, reduce locking stress loss.
Claims (2)
1., for a hydraulic stop plate for steel strand tension, comprise stretch-draw jack and steel strand wires,
It is characterized in that: steel strand wires one end is anchored in anchor hole by stretching into grouting soil, the other end
Outside Rock And Soil, interface uses anchorage to be fixed with anchor plate；
Steel strand wires outside Rock And Soil sequentially pass through anchor plate, anchorage, intermediate plate, bearing plate, hydraulic means
And stretch-draw jack, then use moveable anchor to be fixed, hydraulic means passes through high-pressure oil pipe and hydraulic pump phase
Even, hydraulic pump arranges relief valve and digital display manometer.
Hydraulic stop plate the most according to claim 1, it is characterised in that: also include hydraulic pressure
The supporter of device both sides.
