Description
Technical field
The present invention and a kind of stream are moulded basement cushion cap base plate under shape soil property and are inverted construction technology and knotStructure, belongs to foundation construction technical field technical field.
Background technology
Along with the quickening of urbanization process and the minimizing increasingly of land resource, the mankind are to the underground spaceDemand and rely on more and more stronger, the building foundation of answering is in contrast more and more darker, is positioned atThe difficulty of construction that stream is moulded basement bottom board under shape soil property is more and more higher, and general employing put slope or build by laying bricks or stonesBrick loose tool, but stream mould shape soil property transfer slope easily occur landslide cause doing over again, and construct intoDegree slowly, has a strong impact on the construction speed of whole base plate, and stream is moulded under shape soil property brick loose tool alsoEasily collapse, the backfill of the back side soil of brick loose tool is easily pushed brick loose tool and is caused and cave in, equally to constructionProgress has a strong impact on, and " cheating in hole " reinforcing is also difficult point. Existing technical scheme is at streamMould under shape soil property very undesirable in basement construction
Summary of the invention
The object of the invention is to, provide a kind of working procedure simple, the stream of reliable in quality is moulded shapeUnder soil property, basement cushion cap base plate is inverted construction technology and structure, exists to solve current conventional artMould the problem that runs into landslide in basement construction or cave under shape soil property, thereby overcome prior artDeficiency.
Technical scheme of the present invention:
A kind of stream is moulded basement cushion cap base plate under shape soil property and is inverted construction technology, and this stream is moulded shape soil propertyLower basement cushion cap base plate is inverted construction technology and is comprised the following steps:
Step 1, foundation ditch are made; Foundation ditch is according to required construction base areas and cushion cap bottom surface markHigh determine, the excavation area that is specially foundation ditch is more than or equal to base areas, the opening of foundation ditchDig the degree of depth to the following 5cm～50cm in absolute altitude position, cushion cap bottom surface, then according to Design Requirement DrawingPosition is in the stake of foundation ditch face fabrication.
Step 2, plain concrete cushion layer and construction of waterproof layer; On foundation ditch face, construction element is mixed successivelySolidifying soil padding and watertight composition, after completing, watertight composition can reach absolute altitude position, cushion cap bottom surface.
Step 3, base plate and bearing platform construction; Base plate and cushion cap be construction simultaneously as a whole, whereinBearing platform construction is on engineering pile correspondence position, and base plate and cushion cap are all with absolute altitude position, cushion cap bottom surfaceConstruction, constructs from waterproof aspect, and construction of bottom plates is to plate top surface absolute altitude position, and cushion cap is executedWork is to cushion cap end face absolute altitude position, and cushion cap post is constructed on cushion cap.
Step 4, the construction of drainage layer; Gap backfill packing material between each cushion cap, its backfill is highDegree position is lower than cushion cap end face absolute altitude 1cm～10cm.
Aforesaid stream is moulded basement cushion cap base plate under shape soil property and is inverted in construction technology, described fillingMaterial is on-the-spot concrete piece or the rubble reclaiming in broken armored concrete.
The of the present invention a kind of stream building according to above-mentioned technique is moulded under shape soil property at the bottom of basement cushion capPlate inverted structure is that this structure comprises the engineering pile in foundation ditch, is provided with successively element mixed at the bottom of foundation ditchSolidifying soil padding and watertight composition, base plate and cushion cap are placed on watertight composition as a whole, packing materialBe placed between each cushion cap, the height after its backfill is lower than cushion cap end face absolute altitude 1cm～10cm.
Aforementioned stream is moulded under shape soil property in basement cushion cap base plate inverted structure, the watertight composition after completingHeight is consistent with cushion cap bottom surface absolute altitude.
Compared with prior art, the present invention is useful in stream and moulds basement cushion cap base plate under shape soil propertyIn construction, link up with designing institute by on-the-spot, base plate bottom surface absolute altitude and cushion cap bottom surface absolute altitude are establishedPut at same position, then, by disposable excavation, directly foundation ditch is dug to absolute altitude position, cushion cap bottom surfacePut following 5cm～50cm, and then settle mixed earth bed course and watertight composition in foundation ditch bottom,After complete the construction of base plate and cushion cap, adopt above construction technology, can effectively avoid because of at the bottom of cushion capFace absolute altitude is different with base plate bottom surface absolute altitude and be forced to allow base plate and cushion cap construct respectively, specialAll lower than base plate bottom surface absolute altitude, if separately construction need be executed at base plate at cushion cap bottom surface absolute altitudeIn work engineering, interspace in advance to later stage bearing platform construction, the base plate of this gap must put slope orBuild brick loose tool by laying bricks or stones, but as soil property be that stream is moulded shape, be easy to cause landslide or cave in and cause and returnWork, and if cushion cap bottom surface absolute altitude different with base plate bottom surface absolute altitude, the mixed earth bed course of element and anti-Water layer is very difficult construction also. If therefore adopt construction technology of the present invention, not only can easily constructThe mixed earth bed course of element and watertight composition, and base plate and cushion cap can be used as an entirety, greatly strengthensThe intensity of cushion cap, the construction and installation of the mixed earth bed course of element and watertight composition are also very convenient, and elementMixed earth bed course and watertight composition all, on the same face, therefore mix earth bed course and intensity and watertight compositionWaterproof effect can be guaranteed, and utilize and reclaim the concrete piece of broken reinforced concrete inner supportBackfill is gap location between each cushion cap, carries out the construction of drainage layer, material-saving, energy-conserving and environment-protective, the present inventionConstruction technology is simple, easy to operate, can greatly save construction cost, energy-conserving and environment-protective, effectObviously.
