Description
Technical field
The utility model belongs to base pit engineering technical field, and in particular to support, anchor cable post-tensioning HU types are gone along with sb. to guard him before a kind of steel pipe
Structure and its application process.
Background technology
For the base pit engineering in the range of cutting depth 5m, the building enclosure form one used at present in existing support technology
As using Cement-soil Gravity enclosure wall, shaped steel Soil-cement Wall, slope excavate.
Cement-soil Gravity enclosure wall is characterized in " grid-like " soil cement of the soil-baffling structure by multiple row lap connection in length and breadth
Stake composition, is using cement based material as curing agent, is stirred curing agent and foundation soil by force using shotcrete construction by Mixing Machine
Mix, formed lap connection, have the reinforcing body barricade of certain thickness and building-in depth, conduct oneself with dignity by wall, wall bottom frictional resistance and
The passive earth pressure stabilization wall of the following soil body in excavation of foundation pit face before wall, to meet the monolithic stability of enclosure wall, stability against over turning, resist
Sliding stable and control deformation of wall etc. requires.Its advantage is：Without support in general hole, it is easy to quickly cut the earth, has earth-retaining concurrently and stop
The dual-use function of water.Shortcoming is：Bit andits control ability is weaker, construction quality is unmanageable, economy is general.
Shaped steel Soil-cement Wall be in the triaxial cement stake of lap connection insert shaped steel formed compound earth-retaining every
Water-bound.Its advantage is：It is wider to be applicable soil property scope, it is small to surrounding environment influence, barrier performance is good, environmental protection and energy saving, is applicable soil
Layer scope wide, short time limit, reduced investment etc..Shortcoming is：For 5m within every meter of cost of foundation ditch it is higher and change with the duration, and
Construction requirement is higher, and cement piling quality is difficult to control.
It is a kind of Pit Excavation Methods for setting oblique slight slope using staying that slope, which is excavated, it is characterized in that under non-support measure,
By increasing width suitable for reading of cutting the earth, while take classification slope, bank protection, precipitation etc. to maintain the ancillary method of stability of slope, can prevent
Only native wall avalanche, stability of slope in digging process is kept, there is the advantages of duration is shorter, low cost, shortcoming is slope slope than wanting
Ask larger, stability of slope requirement and width requirement suitable for reading need to be met simultaneously, and surrounding enviroment are had a great influence.
In summary, current foundation pit supporting construction can not also recycle and reuse, also without both economical and safe
Go along with sb. to guard him mode.
Utility model content
The purpose of this utility model is according in place of above-mentioned the deficiencies in the prior art, there is provided before a kind of steel pipe after support, anchor cable
Draw HU type building enclosures, the building enclosure by outside foundation ditch sideline certain distance set by the collar tie beam that bears down on one, H profile steel, U-shaped steel plate
The fabricated construction that stake and one group of steel pipe, one group of anchor cable form, to reach enhancing foundation ditch crater wall stability and building enclosure
The controllable purpose of cost.
The utility model purpose is realized and completed by following technical scheme：
Before a kind of steel pipe support, anchor cable post-tensioning HU type building enclosures, it is characterised in that the building enclosure include bear down on one collar tie beam,
H profile steel, U-shaped steel sheet pile and one group of steel pipe, one group of anchor cable；The H profile steel, U-shaped steel sheet pile be inserted in nature soil layer and with institute
The collar tie beam that bears down on one is stated to be vertically arranged；One end of the steel pipe is connected with the collar tie beam that bears down on one, and with the H profile steel, U-shaped steel plate
Stake is set in 15 °~85 ° angles；The anchor cable sets in 15 °~85 ° angles with the H profile steel, U-shaped steel sheet pile, and is anchored at
Bear down on one collar tie beam top.
The steel pipe is at least made up of row's steel pipe, the anchor cable is at least made up of row's anchor cable.
The H profile steel, U-shaped steel sheet pile, connect arrangement with U-shaped steel sheet pile interval by H profile steel and form.
Described being connected refers to there is at least one set of positioning hole on the collar tie beam that bears down on one, and anchor cable stretches into corresponding
In the positioning hole, fixed by anchorage and the collar tie beam that bears down on one, steel pipe, H profile steel, U-shaped steel sheet pile and the collar tie beam company of bearing down on one
It is integrated, H profile steel, U-shaped steel sheet pile top stretch out collar tie beam top and be no less than 500mm.
Described anchor cable construction one end in the soil body is provided with anchoring body.
Described anchor cable is used to carry out tensioning with command displacement.
The utility model has the advantages that having both earth-retaining, sealing multiple action, soil deformation is constrained, enhances Foundation Pit
It wall stability, can uprightly excavate, avoid the problem of conventional slope excavation method occupied ground face is big, while eliminate conventional water
Soil gravity type enclosure wall, overcome its speed of application slow, the shortcomings of cost is high, and wall quality is difficult to control, and cost is controllable, gram
Taken shaped steel Soil-cement Wall cost because the duration change the shortcomings that, can it is wide be applied to 7m within base pit engineering；Utilize H types
The characteristics of steel, U-shaped steel sheet pile, steel pipe and anchor cable can be reclaimed conveniently, it is recyclable after construction, recycle, economy can
Greatly enhance.
