Description
Technical field
The present invention relates to a kind of soft foundation pouring pile head waterproof and construction method thereof, is the realm of building construction.
Background technology
The building foundation waterproof problem of complicated geological environment is the tackling key problem emphasis of technical field of buildings always, the present invention is that engineering pile pile crown waterproofing node way taking soft foundation environment is as research object, with the actual problem running into of engineering in conjunction with existing job specfication, atlas, the scientific and technical innovation of carrying out as object to improve engineering foundation waterproof quality.
Summary of the invention
For achieving the above object, the invention discloses a kind of soft foundation pouring pile head waterproof, the technical scheme adopting is: pile crown waterproof comprises polyurethane waterproof coating, waterproof roll, sealing compound and waterproofing mortar, does polyurethane waterproof coating enhancement Layer at pile crown surrounding, top and periphery; Double-sided self-adhesive waterproof coiled materials is to pile crown root; Pile crown surrounding seals by sealing compound; Pile crown protrudes bedding plane surrounding and waterproofing mortar is made at top.
Further, described polyurethane waterproof coating enhancement Layer is that 2 ㎜ are thick, expands to periphery 500 ㎜ scopes; Described double-sided self-adhesive waterproof coiled materials is that 4 ㎜ are thick, affixes to pile crown root; Described waterproofing mortar is thick is 20 ㎜, and proportioning is 1:2.5.
The invention also discloses a kind of soft foundation pouring pile head waterproof construction method, comprise following working procedure: the first step, base concrete cushion construction; Second step, builds one deck pea gravel concreten by pile crown surrounding and top, looks for round pile body levelling stake top; The 3rd step, making cement mortar levelling layer on bedding plane; The 4th step is brushed base treatment agent one time on cement mortar screeding layer; The 5th step, pile crown surrounding, top and periphery do polyurethane waterproof coating enhancement Layer; The 6th step, double-sided self-adhesive waterproof coiled materials is to pile crown root; The 7th step, pile crown surrounding seals by sealing compound; The 8th step, pile crown protrudes bedding plane surrounding and waterproofing mortar is made together in top; The 9th step, does pea gravel concreten topping on waterproof roll layer.
Further, in the first step, the construction process of base concrete bed course is: substrate equating after excavation of foundation pit → put architecture basics sideline adds 300 ㎜ control lines → install bed course limit mould → follow closely in foundation ditch absolute altitude control height reinforcing rod, 4 meters of spacing in length and breadth → according to construction flowing water section, C20 blinding concrete is built in segmentation, thickness is not less than 150 ㎜, before bracing wire is closed flat concrete surface → final set on absolute altitude control reinforcing rod, receive light processing → cover film, water seasoning.
Further, in second step, the pile body that exposes outside base concrete bed course is looked for to circle, the levelling of stake end face.Construction process is: pile concrete epidermis picks cutter, the loose stone in stake top and reject → do circular mode with three-ply board ribbing hoop, adds 30 ㎜ hassock pieces → get rid of the cotton felt water seasoning of the pea gravel concreten that reinforcing bar subscript goes out the high grade of absolute altitude control line → build → cover outward at pile crown between Mo Nei and pile body.
Further, in the 3rd step cement mortar screeding layer construction, according to mat surface planeness and defect situation, concrete cushion is carried out to leveling, mainly concrete mats aspect out-of-flatness of having peeling, dusting, pin nest, crack and flowing water section separated place etc., and lead the foot of a wall portion, the cloudy male trowel circular arc of the well that catchments; Construction process is: cutter cleaning → fault location sprinkle water moistening, trickle mud → the smear thick 1:2 cement mortar screeding of 20 ㎜ → lead the foot of a wall portion, the 50 ㎜ circular arc → compacting maintenances of the cloudy male trowel diameter of the well that catchments are picked in fault location surface.
Further, in the 5th step, pile crown surrounding, top and periphery 500 ㎜ scopes are done the thick polyurethane waterproof coating enhancement Layer of 2 ㎜; Construction process is: the cleaning of concrete mats aspect, clear away the foreign material → 500 ㎜ place setting-outs outside pile body limit such as floating ash, control polyurethane boundary of works area → point three times brushing polyurethane waterproof coatings, the time interval with last all over hand by sticky being advisable not, pile crown gets rid of reinforcing bar place outward and wants emphasis brushing → inspection to have or not omission → be coated with and brush one times polyurethane → evenly shed one deck peastone in stake top bit, constructs in order to stake top waterproofing mortar.
Further, in the 6th step, the thick waterproof roll of large paving of base concrete bed course 4 ㎜, until engineering pile edge at one's side; Construction process is: base mat aspect cleans out → put paving line at base mat aspect bullet, 1 meter of coiled material fabric width, lap width is that 80mm paving line spacing is 920mm → lead the foot of a wall portion, the negative and positive place of the well that catchments carries out extra play → inspect for acceptance → along the large face waterproof roll of the sticky paving of paving, it between coiled material and bed course, is empty paving, it between coiled material, is self-adhesion overlap joint, the careful compacting of lap-joint → coiled material is met engineering pile place, along pile body circular arc cutting coiled material, make waterproof roll prop up pile body, coiled material and pile body spacing are not more than 20mm → coiled material and pile body periphery polyurethane enhancement Layer will cement.
Further, in the 7th step, between waterproof roll and pile body, use the shutoff of Special seal cream; Construction process is: waterproof roll and pile body junction are cleaned out → have or not omission along the gap → compacting sealing compound → inspection between pile body border sealing compound shutoff waterproof roll and pile body.
Further, in the 8th step, pile crown protrudes concrete mats aspect surrounding and 20 ㎜ 1:2.5 waterproofing mortars are made at top; Construction process is: by match ratio mixing waterproofing mortar → waterproofing mortar construction is cleaned out → carried out in waterproofing mortar construction place, and smear and flatten → cover cotton felt water seasoning.
Further, in the 9th step, on waterproof roll layer, do the thick C20 pea gravel concreten of 50 ㎜ topping; Construction process is: waterproofing mortar layer check and accept complete and clean out → copy and survey basis end absolute altitude with level gauge, on waterproofing course, make the segmentation of protective layer thickness control ash cake → according to construction flowing water section and build waterproofing protection layer concrete → receipts face and smear flatten → water seasoning.
Beneficial effect of the present invention is as follows:
The present invention compares with traditional basic pile crown waterproofing node way, polyurethane, waterproof roll, sealing compound, 4 kinds of waterproofing courses of waterproofing mortar have been made respectively at pile crown place, there is rigid waterproofing also to have flexible water, in pile crown joints complexity, distortion more greatly, under the medium unfavorable conditions of influence on groundwater environment, can have good applicability for a long time.By multi-way prevention, prevent that breakthrough from appearring in pile crown place, to ensure workmanship.
