The specific embodiment
As shown in Figure 1, 2, 3, before carrying out the many pile cap constructions of manhole stake, in foundation ditch 111, carry out earthwork construction earlier in the prior art, construct out and satisfy the pile driving construction operating surface 101 of predetermined manhole pile driving construction, as shown in Figure 2, often not distinguishing stake this moment is stake or cushion cap stud in the cushion cap.Rezone or whole unwrapping wire, test the construction of carrying out stake behind the position of line justification stake, comprise and digging in the manhole stake cubic metre of earth, carry out pile wall 104 constructions, colligation stake core reinforcing bar is built a core concrete 103 and is carried out a maintenance of core concrete.After treating that the inside and outside pile driving construction of cushion cap is all finished, pile driving construction team withdraws from, the admission of structure construction team.As shown in Figure 3, dig earlier cushion cap etc. cubic metre of earth and construction this moment except empty stake concrete dado 105, carry out again the construction of cushion cap topotype, and carry out the reinforced concretes constructions such as structure base slab 107, cushion cap, finish whole construction.
The many pile framings of manhole stake of the present invention the earthwork, topotype and the stake integrated rapid constructing method preferred embodiment in, shown in Fig. 4,5, may further comprise the steps: S1 presets near the absolute altitude 201, such as the step 210 among Fig. 4 on earthwork construction to cushion cap top in foundation ditch; S2 is according to shape and the position of default cushion cap, excavate the cushion cap earthwork near the default absolute altitude of cushion cap soil layer, form cushion cap hole 221, such as the step 220 among Fig. 4, this cushion cap was cheated for 221 ends and is tried one's best construction near this suspended deck structure concrete bed course 203, and satisfied the construction requirement of manhole stake 204, cushion cap topotype 205; S3 determines 204 positions of manhole stake and carries out pile driving construction, such as the step 230 among Fig. 4; S4 construction bearing platform soil puts in place, carries out 205 constructions of cushion cap topotype, such as the step 240 among Fig. 4.Wherein, according to the different different arrangement and method for construction of determining stake, topotype, earthwork, draining of rain, water and cushion cap topotype 205 etc., thereby safety, fast finish the earthwork, with the integrated construction of topotype.
According to various actual conditions in the foundation ditch, the Specific construction schemes under different situations such as the below earthwork of the many pile framings of specific descriptions manhole stake of the present invention, topotype and the integrated rapid constructing method king-pile of stake, topotype, the earthwork, draining:
Orient earlier near the absolute altitude of the base plate earthwork construction default cushion cap according to designing requirement, carry out earthwork construction according to this absolute altitude, form foundation ditch 219.According to various actual conditions in the foundation ditch 219, as whether rainy season, the underground water depth, what, cushion cap position, size, the depth, the constructure scheme of stake in tight, rational, the feasible cushion cap earthwork of numerous factor establishments, cap mold, the cushion caps such as the stake core concrete depth.
When the cushion cap earthwork construction, rain in the sky, underground water are very big to its construction infection.Saturating the adverse effect analysis of rainwater, select safety, rationally effective arrangement and method for construction.The construction of the cushion cap earthwork can be according to on-the-spot and Construction Plan unified construction, but also subregion or single cushion cap are constructed.If rainwater is few, or when having no adverse effect, when cushion cap top earthwork construction after the condition that satisfies the construction bottom cushion cap earthwork, according to construction plan, the outer shoveling of Accurate Determining cap mold plan-position.Select suitable shoveling to put the gradient, appropriate to the occasion the digging under the cushion cap foot mat of cutting the earth according to pile construction needs in the depth of cushion cap, soil property quality, the cushion cap.
Owing to mainly be that stake is stressed in the cushion cap, thereby cubic metre of earth can suitably the backbreaking of at the bottom of the cushion cap topotype and cushion cap side, be fit to come operation with machinery.Do not backbreak or owe to dig be not can not, just workman's the spirit of bearing hardships may be worse and worse, and is more by manually being unfavorable for rapid construction.After cutting the earth, machinery determines whether earlier to rebuild with manually going according to cushion cap topotype and pile construction plan and shaping situation.If construction bearing platform stake behind the first construction bearing platform mould, then rationally use is artificial, and finishing cushion cap side soil, subsoil can utilize machinery that unnecessary soil is dug and transport to the predetermined position of constructing.If the stake in the construction cushion cap is earlier cut the earth minimum normal, the safe construction that guarantees stake just, standard can be higher better certain.And in the prior art, by the time pile driving construction is when carrying out the excavation of the cushion cap earthwork again after finishing, mechanical work is not too convenient, and this preferred embodiment adopts the mechanical work more can the reduction of erection time by contrast, to reach the purpose of rapid construction.
Will take into full account problem rainproof, draining if rain digs on the cushion cap more, if the underground water height, water percolating capacity is big, also to solve earlier fall, drainage problem.If disorderly dig by force, especially more deeply, bigger cushion cap, to add soil property more bad, many unthinkable not good things all might take place.So top rain is many, rain is big, want significant care careful to native construction of cushion cap when the high water percolating capacity of following water level is big.
Because rainwater is bigger than other position impact to the relevant construction in the cushion cap, when doing the anti-draining of bearing platform construction, must comprehensively consider.Take full advantage of the inside and outside facility system of foundation ditch mutually support, cooperate, with prevent in rational cost, the careful solution cushion cap, fall, the problem of draining, guarantee in the cushion cap cubic metre of earth and other easy construction, safety, fast, specifically can be with reference to following description:
To rainwater, at first should dam outside foundation ditch, prevent from entering in the hole as far as possible.To cushion cap, in construction foundation pit more than the stake operating surface cubic metre of earth the time, can dig temporarily in the part cushion cap and to be temporarily falling of constructing of pit earthwork, gully.But in case near construction (or local construction) stake operation or when in the foundation ditch, if will be conscientiously according to soil property situation in the cushion cap when continuing in the construction bearing platform soil, the problems such as the depth whether continue to establish within it with fall temporarily, gully.Because rainwater has uncertainty, do not rain then fall temporarily, gully generally can be anhydrous, when guaranteed, can dig earlier in the cushion cap cubic metre of earth to put in place.But it is a plurality of that perhaps cushion cap has, and do not have also reality not necessarily of rain when digging in the cushion cap soil at every turn.So dig should prevent to rain the negative effect of soil in the cushion cap, get lodged in possible rainwater outside the cushion cap and do not have negative effect place as far as possible as far as possible to soil construction in the cushion cap.Even want with low advantage in the cushion cap, wait otherwise this cushion cap in wouldn't construct, or construction to possess safe be used as fall, in the condition of gully.
Relatively good anti-, the row of rainwater, and underground water is just very complicated.If there is foundation ditch water-stop curtain interception water effect better, water level is easy to fall, and difficulty is little.If effect is not so good, that also can be pretty troublesome.This trouble not only affects integrated relevant construction in the cushion cap, also affects the later on construction of suspended deck structure, and the scheme of safe and feasible must be arranged for this reason.The method of precipitation is diversified, to the manhole stake and Yan Youduo self precipitation method of stake.The cushion cap king-pile is many, digs to reduce that its water level can be selected in only not too tight in the pile driving construction duration or be a selection by other lower.The general pile driving construction duration is more anxious, and multiple other method is preferably arranged.Such as: if the cushion cap area occupied is big, the precipitation of can in cushion cap, digging pit earlier, but secondary not in place or three times are once fallen.So not only fallen water in the cushion cap, but also dug cushion cap soil, but will note the negative effect to cushion cap limit mould soil stabilization, then should not do like this (scope that especially may produce stream mud, quicksand) bigger than normal.
In many to rainwater, big, groundwater table height, the many ground of infiltration, to cushion cap fall, before draining not only will consider construction, also to consider construction after.If cushion cap bottom application worker's catch pit can ensure from now on suspended deck structure construction and quality safety then solution at the bottom of cushion cap.If water is many, big, or repair for being preferably in the cushion cap limit for the purpose of bearing platform construction safety, the architecture quality that special use is fallen, catch pit 206, step 215 as shown in Figure 4.Cushion cap is little, shallow can be a little close to the cushion cap; Deeply can far, catchmenting in the cushion cap be pumped out in hole or pipe laying introducing gully greatly.If this class catch pit is outlying or on the cushion cap limit from cushion cap, can dig out ditch during the earthwork of construction cushion cap, well location comes, and is convenient to the back and uses manpower less, also calculate and cubic metre of earth once survive! Construction cushion cap limit special use is fallen, catch pit 206 digs out ditch, will note not influencing the construction of subsequent handling when well location comes, and fully take into account the negative effect of rainwater, can delay by normal construction if condition such as rainwater is too big too much is bad.If dig out ditch, well location, this position can not be located at has negative effect place to structure: as rain etc. should consider earlier to dig out ditch, well is constructed.Fall, the pipe trench of gully 206 to hang down some guarantee cushion caps at the bottom of water can normally discharge.This pipe trench can also can use suitable tubing with brick, and assurance water can normally be discharged and be got final product.Special use is fallen, gully 206 is generally used brick masonry, neglect greatly well depth shallow, need displacement and decide.Special use is fallen, gully 206 construction should be before the construction of cushion cap side form or in the construction, like this before the pile driving construction special use of just constructing after good fall, perhaps gully 206 can be that pile driving construction falls, draining.
After finishing the interior earthwork construction of cushion cap, put, confirmed 204 positions of manhole stake, carry out pile construction in the cushion cap by the corresponding requirements of pile driving construction again, cap mold is afterwards only constructed otherwise affecting pile construction safety all can construct with pile driving construction while or front and back at any time with construction.Because the earthwork has been dug to default cushion cap bottom in this moment cushion cap, save empty stake construction partly long in the prior art, save resource and reduced impact to construction environment.
But this moment, the safety problem of manhole pile driving construction was relatively protruded, safety does not have the what is said or talked about of guarantee, and what is all meaningless, mainly contain which potential safety hazard after changing so, how to solve? the one, the impact of raining or seeping water, can be collected in water in the cushion cap hole and drain in the low hole, also can establish at pile lining and bury vent 218, specially arrange this type of rainwater, to get rid of rainy or to seep water to the impact of manhole pile driving construction.The 2nd, the next door has foreign matter to roll in the stake to hurt sb.'s feelings easily, can strengthen increasing stake mouthful protection, prevents that the foreign matter next door from rolling into.The 3rd, propose the negative effect of native machine: a kind of situation be stake less, cushion cap is shallow, carry native machine normally proposes the soil operation in a high position; thereby but can depress like this cushion cap limit soil or press construction safety in the quick-fried cushion cap brick side form impact stake; but Adopts measure has: add the pressure that cushion cap limit soil or brick side form are dissolved in the lumps of wood, plank or support etc. under the native machine carrying, or the mould or strengthen the early strong intensity of its mortar etc. of early laying bricks.Its another kind of situation is that cushion cap is dark, stake is many, carries native machine and can't directly carry soil for the stake that has, and can place in cushion cap this moment for carrying native machine, carries out secondary or repeatedly hang upside down muck haulage; Also can carry the satisfied construction of native machine needs by special longwell.No matter the cushion cap depth, stake what, relatively the safe course is erection construction operating platform in cushion cap, height is almost high with the operating surface on cushion cap top.This operating platform is solid and reliable, satisfies, the safe construction of related personnel, equipment during convenient construction.The method of setting up this operating platform has multiple choices.As processing, set up special operating platform; Also can utilize existence conditions, realize the safe construction operating platform such as erecting scaffold, boarding, make the pressure of carrying native machine by scaffold or at the bottom of importing cushion cap into, or keep clear of the cushion cap limit, thereby dissolve the pressure of cushion cap limit soil or brick side form.
For the rainwater of cushion cap hole top margin, can cheat the article such as the sclerosis of top margin construction cushion coat or laying waterproof cloth at cushion cap and come rainwater-proof or the downslide of anti-limit thing to flow in the stake.
The stake top construction of stake in the cushion cap can be constructed with reference to old law, and also can put in place in safety, the guaranteed condition of quality is constructed into the cushion cap stake that meets design, code requirement to the stake top next time.Because complexity, the quality of workers of pile driving construction are uneven, there is polytropy in stake core concrete laitance, guarantee that it is inconvenient that an every pile head of core concrete laitance is all handled well.In order to increase the safety stock of pile crown; can be when construction stake epimerite retaining wall 211; take inverted job practices; promptly at construction retaining wall mould or when processing special-purpose retaining wall mould; make big mouthful 212 last; osculum 213 is down, even possible some deficiency of stake core concrete top quality so also can have not big harm to superstructure.This joint of constructing will be put earlier line during retaining wall well and confirms, digs to repair a limit soil and will put in place, will become when retaining wall reinforcement fabrication, colligation to meet the demands thereupon, props up afterwards the retaining wall mould rear construction retaining wall concrete that meets the demands, and finishes the construction of this joint retaining wall.Be also noted that in addition this joint retaining wall since big mouthful 212 upper, osculum 213 can produce the connectivity problem that saves up and down retaining wall lower, thus the perpendicular muscle of retaining wall to control well with lower joint retaining wall rationally, safety is connected; To make its bottom concrete not affect the construction of next joint retaining wall concrete when building an epimerite pile wall concrete.For head it off can strengthen epimerite pile wall 211 diameters or base diameter; Perhaps when next the joint pile wall that is connected with the epimerite retaining wall carries out the concrete construction, water thinner; Perhaps should save pile wall and epimerite stake bottom retaining wall together carries out concrete and builds.
There is not empty retaining wall in the method for above-mentioned pile driving construction, and maintenance is carried out in an inconvenient retaining after the construction of a stake core concrete like this, this moment can pile crown place can suction thing, frequent water seasoning; Also can realize the water storing conservation on stake concrete top at easy water-storing device of stake concrete top construction, this simple and easy water storing conservation device can place in the pile wall or outward, seep water less or not, but one or many uses, have certain retaining satisfy function then can, shown in Fig. 6,7,8,9.This water-storing device can arrange with the soft thing 214 that do not seep water, and this soft thing 214 can be with disposable, cheaply when pile wall 208 interior the setting, such as plastics Bao Mo etc.; This soft thing 214 can adopt when pile wall 208 outer the setting and can repeatedly use, the rational material of cost, such as waterproof cloth, paulin etc.When this soft thing 214 places in the pile wall 208, place the concrete that waters behind the pile wall inner edge quilt to press soft thing 214 bottoms watering a core top concrete 216 before, top can be satisfied the water storing conservation requirement and then can.When requirement places pile wall 208 outer, place tied the pressing less or not in pile wall outside to seep water watering stake core concrete 209 rear lowers, top can be satisfied the water storing conservation requirement and then can.Because soft thing is difficult for supporting oneself, can borrow stake core reinforced frame upright.
Specifically be provided with shown in Fig. 7,9, described storage chamber can be provided with in the following manner: with the soft thing 214 that do not seep water, be bundled in the lateral wall at pile wall 208 tops as oilcloth etc., form the storage chamber 217 of upper end open at stake core concrete 209 tops, the pile construction method of this moment is as shown in Figure 6: S3.2a determines manhole stake stake position in the cushion cap, dig top in the manhole stake according to the default manhole stake size and the degree of depth, as the step 234 among Fig. 6; S3.2b finishes the construction before the default stake core concrete curing, comprises reinforcing bar in construction stake retaining wall, the colligation stake, builds a core concrete etc., as step 235 among Fig. 6; S3.2c uses the soft thing that do not seep water to be bundled in the lateral wall at pile wall top, and the storage chamber that forms upper end open at stake core concrete top carries out the maintenance of stake, as step 236 among Fig. 6.The lower end of the soft thing that do not seep water can also be attached to the inside wall at pile wall 208 tops, carry out a core concrete 209 constructions again, the soft thing that do not seep water is ridden between the inside wall and stake core concrete 209 at pile wall 208 tops, thereby form the storage chamber of upper end open at stake core concrete 209 tops, as Fig. 8, shown in 9, thereby there is water just can guarantee the normal maintenance of a core concrete 209 in the storage chamber as long as guarantee, avoided continually stake core concrete 209 being watered, the pile driving construction flow process as shown in Figure 8 at this moment: S3.3a determines manhole stake stake position in the cushion cap, dig the earthwork in the manhole stake according to the default manhole stake size and the degree of depth, as the step 237 among Fig. 8; S3.3b finishes the construction of a default stake core concrete before building, and comprises reinforcing bar in construction stake retaining wall, the colligation stake, builds a core concrete etc., water again concrete in the pile wall to default absolute altitude following near, as the step 238 among Fig. 8; S3.3c is attached to the inside wall at pile wall top with the soft thing that do not seep water, building a cavity of core concrete top formation upper end open, continuation is built a core concrete to default absolute altitude building a core concrete top, the soft thing that do not seep water is pressed between the inside wall and stake core concrete that is clipped in the pile wall top, the storage chamber that forms upper end open at stake core concrete top carries out the maintenance of stake, as the step 239 among Fig. 8.
After pile driving construction is finished or when pile driving construction carries out or front and back, carry out the construction of cushion cap topotype, as long as this cushion cap topotype construction does not have influence on the interior pile construction of cushion cap safely, thereby avoided only having in the prior art the by the time complete rear construction that just can carry out the cushion cap earthwork and cushion cap topotype of pile driving construction, shortened the construction period.What will be clear that recognizes; an ingredient that has excavated the cushion cap earthwork and cooperated pile driving construction is just protected in the construction of cap mold in the earthwork of the many pile caps of manhole stake of the present invention, topotype and the stake integrated construction; for the duration also not on crucial or leading operation; so only otherwise influence the cushion cap earthwork and pile driving construction, early or all can late.In order to finish early the cushion cap earthwork, stake, the integrated construction of topotype can intert enforcement as early as possible, thereby provide operating surface for structure construction etc. as early as possible.
To sum up summary: in the earthwork, topotype and the incorporate rapid constructing method of stake of the many pile caps of manhole stake of the present invention, by accurate unwrapping wire, control, safety are dug the cushion cap earthwork and are put in place, satisfy the pile driving construction condition and carry out pile driving construction, according to the construction of field condition, situation decision cap mold.And according to season situation, condition such as rainwater, underground water and field engineering geology do preventive action.In guaranteeing cushion cap, construct safe the time, can set up the safe construction operating platform as the case may be, wait the problem such as safe, convenient of construction as solve stake in the cushion cap with the scaffold power transmission.In safety, satisfy and finish fast the cushion cap earthwork, topotype and the integrated construction of stake under the prerequisite of relevant criterion, requirement.
