Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of soft clay area superelevation pile foundation the utility model proposes is heldThe brick loose tool structure of platform is described in further detail. According to explanation and claims below, this practicality is newThe advantage of type and feature will be clearer. Below will by cited embodiment by reference to the accompanying drawings, describe this reality in detailBy novel technology contents and feature. Need in addition explanation, accompanying drawing all adopts the form simplified very much and allUse non-ratio accurately, only in order to convenient, the object of aid illustration the utility model embodiment lucidly.For sake of convenience, hereinafter described " on ", D score is consistent with the upper and lower direction of accompanying drawing, but this is notCan become the restriction of technical solutions of the utility model.
The brick loose tool structure of the soft clay area superelevation pile foundation support table of the present embodiment is described in conjunction with Fig. 1 and Fig. 2, itBe positioned at the dell between pile foundation 20 and cushion cap 10 (being sole plate), brick loose tool structure 30 comprises and being positioned atThe first concrete cushion 31 of dell bottom; Build by laying bricks or stones on the first concrete cushion 31 and along the first concrete matsThe brick wall 32 that layer 31 edge arrange continuously; Brick wall 32 outsides are provided with the backfill layer being made up of graded sand and stone36; The top of brick wall 32 connects the first reinforced concrete circle beam 32d, and the top of backfill layer 36 is provided with second and mixesSolidifying soil padding 34; The corner of brick wall 32 is provided with constructional column one 32a longitudinally arranging along body of wall, every width body of wallSome constructional column two 32b that planar longitudinally arrange.
The brick loose tool structure of a kind of soft clay area of the present utility model superelevation pile foundation support table, is building brick wall 32 by laying bricks or stonesIn process, along body of wall, constructional column one 32a is longitudinally set in brick wall 32 corners, and every width body of wall place planeSome constructional column two 32b are inside longitudinally set, constructional column 32a, 32b are arranged on to the stressed weakness of brick wall 32Position, can strengthen the weight capacity of brick wall 32 entirety; And the top of brick wall 32 is also provided with firstReinforced concrete circle beam 32d, has the space stiffness of brick wall 32 of enhancing and the effect of resistance to overturning, avoidsThe wall crazing phenomenon causing because of differential settlement, oscillatory load etc.; To sum up, brick loose tool of the present utility modelStructure 30, by set up constructional column and reinforced concrete circle beam in brick wall 32, makes constructional column and reinforced concretePedosphere beam forms brick wall " structural framing " jointly, to strengthen the integral rigidity of brick fetal membrane structure 30 and to stablizeProperty, improve the ability of body of wall resistance to deformation, eliminate body of wall because of soil at both sides backfill and concrete vibratingThe potential safety hazard that easily deforms and damage, thus the construction quality of brick loose tool structure 30 ensured.
Preferably, the spacing of adjacent two constructional column two 32b is less than or equal to 2m, this of constructional column two 32bSpacing setting can improve the bearing capacity of body of wall entirety, avoids the stressed weak part at body of wall middle part because of on itPortion's load is excessive and be out of shape.
Preferably, constructional column one 32a and constructional column two 32b are reinforced concrete structure or brickwork construction, forReduce engineering cost, constructional column one 32a and constructional column two 32b of the present embodiment select brickwork construction; Conventionally,When brick wall 32 is highly less than 2m, brick wall 32 thickness are 240mm, and brick wall 32 is while being highly greater than 2m, brickWall 32 thickness are 370mm; For meeting the needs of body of wall load-bearing, constructional column one 32a and constructional column two 32bCross section be the square that the length of side is more than or equal to 500mm, due to constructional column one 32a and constructional column two 32bThickness be greater than the thickness of body of wall, not only strengthened the resistance to overturning of brick wall 32, and reduced brick wall 32Body of wall build thickness by laying bricks or stones, reduced engineering cost.
As shown in Figure 1, in brick wall 32, also arrange respectively and be connected with constructional column one 32a and constructional column two 32b,And the second reinforced concrete circle beam 32c at perforation body of wall middle part is strong in order to the structure of further enhancing brick wall 32Degree.
Please continue to refer to Fig. 1, in the first reinforced concrete circle beam 32d, along continuous straight runs is embedded with some pre-buried steelsMuscle 35, the spacing of adjacent two embedded bars 35 is 200mm~300mm, and one end of embedded bar 35 is pre-Be embedded in the first reinforced concrete circle beam 32d, its other end anchors in the second concrete cushion 34, pre-buried steelSetting up of muscle 35, can make being connected more of the first reinforced concrete circle beam 32d and the second concrete cushion 34For firmly, thereby improve the resistance to overturning of brick loose tool structure 30.
Preferably, one end of imbedding in the first reinforced concrete circle beam 32d of embedded bar 35 has a bendingPortion, kink can improve the bonding strength of embedded bar 35 and the first reinforced concrete circle beam 32d, pre-buriedThe length of reinforcing bar 35 is more than or equal to 2m, can ensure that it has enough anchors in the second concrete cushion 34Gu length.
Please continue to refer to Fig. 1, the rectangular triangle in the longitudinal section of backfill layer 36, the hypotenuse of right angled triangle withThe angle α of horizontal plane is more than or equal to 45 °, because the dell at these brick loose tool structure 30 places is by above-mentioned angleDegree is put slope and is excavated, middle wall outer side large area soil body backfill compared to existing technology, and tool is accliveBackfill layer 36 has reduced soil body backfill and the pressure of casting and compacting of concrete to body of wall to a certain extent, has avoided wallThe phenomenon that body deforms and damages because of outside pressure.
The brick loose tool structure of the utility model soft clay area superelevation pile foundation support table is described below in conjunction with Fig. 1 and Fig. 230 work progress:
One,, according to the size earth excavation of measurement and positioning and locally deep pit, be more than or equal to 45 ° according to angle α and putSlope, and build the first concrete cushion 31 in dell bottom;
Two, above the first concrete cushion 31 and along its edge, build continuously brick wall 32 by laying bricks or stones, brick wall 32Corner be provided with constructional column one 32a longitudinally arranging along body of wall, every width body of wall institute planar longitudinally arrangesSome constructional column two 32b, are also provided with in brick wall 32 respectively and are connected with constructional column 32a, 32b, and connect wallThe second reinforced concrete circle beam 32c of body, the top of brick wall 32 is provided with the first reinforced concrete circle beam 32d,In the first reinforced concrete circle beam 32d, be connected with embedded bar 35;
Three, brick wall 32 outsides adopt graded sand and stone backfill compaction in layers to the compactness of designing requirement to form backPacking course 36 is built the second concrete cushion 34 on backfill layer 36, and the other end of embedded bar 35 is anchored intoThe second concrete cushion 34, the brick wall 32 inner side cement mortar 20mm that plasters is thick, thereby completes brick loose tool structure30 construction.
