Abstract
The utility model body supports H type component building enclosures before being related to a kind of steel pipe, it is characterised in that the building enclosure includes bear down on one collar tie beam, Soil-cement Wall, H types component and one group of steel pipe；The H types component is inserted in Soil-cement Wall and is vertically arranged with the collar tie beam that bears down on one, and one end of the steel pipe is connected with the collar tie beam that bears down on one, and with the angled setting of H types component.The utility model has the advantages that：H types component is prefabricated, easy construction；Low cost, promotes facility；Have reinforcement antiskid, earth-retaining, sealing multiple action concurrently, go along with sb. to guard him in the range of the anti-slide performance of the soil body, resistance capacity to deformation significantly improve.
Description
Technical field
The utility model belongs to base pit engineering technical field, and in particular to H type component building enclosures are supportted before a kind of steel pipe.
Background technology
For the base pit engineering in cutting depth 5m, the building enclosure form used in current existing support technology is typically adopted
Excavated with Cement-soil Gravity enclosure wall, shaped steel Soil-cement Wall, slope.
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 with cement based material as curing agent, by Mixing Machine using shotcrete construction by curing agent and
Foundation soil is stirred by force, formed lap connection, have the reinforcing body barricade of certain thickness and building-in depth, by wall deadweight,
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. are required.Its advantage is：Without support in general hole, it is easy to quick digging
Soil, has the dual-use function of earth-retaining and sealing concurrently.Shortcoming is：Bit andits control ability is weaker, construction quality is difficult to control to, economy
Typically.
Shaped steel Soil-cement Wall be lap connection triaxial cement stake be inserted into shaped steel formation compound earth-retaining every
Water-bound.Its advantage is：It is applicable that soil property scope is wider, barrier performance small to surrounding environment influence is good, environmental protection and energy saving, be applicable soil
Layer scope wide, short time limit, reduced investment etc..Have the disadvantage：For 5m within every meter of cost of foundation ditch it is higher and with the duration change, and
Construction requirement is higher, and cement piling quality is difficult to control.
It is a kind of Pit Excavation Methods for using and staying and set oblique slight slope that slope is excavated, it is characterized in that under non-support measure,
By increasing width suitable for reading of cutting the earth, while taking classification slope, bank protection, precipitation etc. to maintain the ancillary method of stability of slope, can prevent
Only native wall avalanche, keeps stability of slope in digging process, and, the advantage of low cost shorter with the duration has the disadvantage slope slope than wanting
Ask larger, need to simultaneously meet stability of slope requirement and width requirement suitable for reading, and larger are influenceed on surrounding enviroment.
In sum, current foundation pit supporting construction depth 5m or so excavation area it is big, go along with sb. to guard him length foundation ditch long also
Do not have both economical and safe to go along with sb. to guard him mode.
Utility model content
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, there is provided H type components are supportted before a kind of steel pipe
Building enclosure, the building enclosure is set by the collar tie beam that bears down on one, Soil-cement Wall, H type structures by the certain distance outside foundation ditch sideline
Part and one group of fabricated construction of steel pipe composition, it is controllable to reach enhancing foundation ditch crater wall stability and building enclosure cost
Purpose.
The utility model purpose is realized being completed by following technical scheme：
H type component building enclosures are supportted before a kind of steel pipe, the building enclosure includes bear down on one collar tie beam, Soil-cement Wall, H types
Component and one group of steel pipe；The H types component is inserted in Soil-cement Wall and is vertically arranged with the collar tie beam that bears down on one, the steel
One end of pipe is connected with the collar tie beam that bears down on one, and is set in 5 °~60 ° angles with the H types component.
The steel pipe is at least made up of row's steel pipe.
The Soil-cement Wall is made up of two row's mixing piles of lap connection, inserts described in the Soil-cement Wall
H type components.
Described being connected refers to that the H types component, one end of steel pipe whole are 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 utility model has the advantages that, have both reinforcement, earth-retaining, sealing multiple action, soil deformation is constrained, enhance base
Hole crater wall stability, can uprightly excavate, it is to avoid conventional slope excavation method occupied ground face big problem, while significantly reducing
The traditional cements soil gravity type enclosure wall scale of construction, overcomes its speed of application slow, and cost is high, the shortcomings of wall quality is difficult to control, and
Cost is controllable, overcomes the shortcoming that shaped steel Soil-cement Wall cost changes by the duration, wide can be applied to foundation ditch work within 7m
Journey；The characteristics of can conveniently being pulled out using steel-tube construction, constructing, it is rear recyclable to finish, and recycles, and economy can be greatly enhanced.
