Description
Technical field
The utility model belongs to base pit engineering technical field, and in particular to support, anchor cable post-tensioning H type components enclose before a kind of steel pipe
Protection structure.
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, the cement earth pile be using cement based material as curing agent, by Mixing Machine using shotcrete construction by curing agent and
Foundation soil stirs by force, formed lap connection, have the reinforcing body barricade of certain thickness and building-in depth, conduct oneself with dignity by wall,
The passive earth pressure stabilization wall of the following soil body in excavation of foundation pit face before wall bottom frictional resistance and wall, to meet the overall steady of enclosure wall
Fixed, stability against over turning, Against Sliding Stability and control deformation of wall etc. require.Its advantage is:Without support in general hole, it is easy to quickly dig
Soil, have the dual-use function of earth-retaining and sealing concurrently.Shortcoming is:Bit andits control ability is weaker, construction quality is unmanageable, economy
Typically.
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 is depth 5m or so excavation area is big, construction space is small, goes along with sb. to guard him length
Spend long foundation ditch and also go along with sb. to guard him mode without both economical, safety, quick construction.
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 H type component building enclosures and its application process, the building enclosure by outside foundation ditch sideline certain distance set by the circle that bears down on one
The fabricated construction that beam, cement mixing method, H types component and one group of steel pipe, one group of anchor cable form, to reach enhancing Foundation Pit
Wall stability and the controllable purpose of building enclosure cost.
The utility model purpose is realized and completed by following technical scheme:
Support, anchor cable post-tensioning H type component building enclosures before a kind of steel pipe, it is characterised in that the building enclosure includes bearing down on one
Collar tie beam, cement mixing method, H types component and one group of steel pipe, one group of anchor cable;The H types component is inserted in cement mixing method
And be vertically arranged with the collar tie beam that bears down on one, one end of the steel pipe is connected with the collar tie beam that bears down on one, and with the H types component
Set in 15 °~85 ° angles;The anchor cable is set with the H types component in 15 °~85 ° angles, and is anchored at the collar tie beam that bears down on one
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 cement mixing method is made up of the five axle cement mixing methods or two row's twin shaft cement mixing piles of lap connection,
The H types component is inserted in the cement mixing method.
The insertion depth for applying depth and being more than H type components of the cement mixing method, and the excavation of both greater than foundation ditch is deep
Degree.
Described be connected refers to that the H types component, one end of steel pipe are whole and poured in the collar tie beam that bears down on one.
Described steel pipe is applied in oblique high-pressure rotary jet grouting pile.
The positioning hole and anchorage reserved when described anchor cable is poured by the collar tie beam that bears down on one are anchored at collar tie beam top of bearing down on one.
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 reinforcement, earth-retaining, sealing multiple action, soil deformation is constrained, enhances base
Crater wall stability is cheated, can uprightly excavate, avoid the problem of conventional slope excavation method occupied ground face is big, while significantly reduce
The shortcomings of traditional cements soil gravity type enclosure wall scale of construction, overcomes its speed of application slow, and cost is high, and wall quality is difficult to control, and
Cost is controllable, overcome shaped steel Soil-cement Wall cost because the duration change the shortcomings that, can it is wide be applied to 7m within foundation ditch work
Journey;It is the characteristics of can conveniently being reclaimed using steel pipe and anchor cable, recyclable after construction, recycle, economy can increase greatly
By force.
