Abstract
The utility model discloses a jacking device of a simply supported plate on a retaining wall, which comprises the simply supported plate for transition between a front bearing platform and a rear land region, wherein the retaining wall is arranged below the land side of the simply supported plate, a plurality of jacking reserved holes are arranged at the top part of the retaining wall, and a jacking beam which is placed on the jacking reserved holes is arranged between the retaining wall and the simply supported plate. The structure has the following advantages: the simply supported plate does not need to be revealed during maintenance and construction, and the retaining wall can be heightened by only needing to jack the simply supported plate, thereby greatly shortening the maintenance working period and reducing the production impacts to the minimum.
Description
Technical field
The utility model belongs to harbour, water conservancy construction field, relates to a kind of lift-up device that is used for jacking simply supported slab on the retaining wall specifically.
Background technology
In recent years, along with international container transport to maximize, the deep water development, China's object of construction production of building harbour of reclaiming fields from the sea around on the island constantly increases.The land-based area of many engineerings adopts the mode of carrying out quick backfill on deep mud to form.Under this type of geological conditions, land-based area will inevitably produce a certain amount of posterior settlement after building up, and harbour adopts the small pile foundation pattern of posterior settlement amount more, and for to make full use of limited land-based area resource, harbour and land-based area are not established access bridge usually and directly joined.For adapting to the differential settlement between harbour and the land-based area, the simply supported slab transition is set between harbour and revetment generally.
The transition of employing simply supported slab can effectively adapt to the differential settlement between harbour and the revetment, but because land-based area polyphyly backfill formation fast on deep mud, its settlement after construction is bigger usually, and the simply supported slab span is limited, therefore after engineering is normally runed the several years, need take usually to adjust adding the pouring concrete paving on the simply supported slab or the retaining wall below the simply supported slab is connect high measure.If on simply supported slab, add the pouring concrete paving, then can increase the load of simply supported slab, simply supported slab is as the excessive destruction that easily causes shelving of tilting simultaneously; Generally need open simply supported slab earlier and could construct and retaining wall connects height.Therefore, these conventional methods all exist the construction period long, and the big defective of loss stops production.
The utility model content
The technical problems to be solved in the utility model provides simply supported slab lift-up device on a kind of retaining wall, in the time of the jacking simply supported slab, is convenient to safeguard construction, can the reduction of erection time.
The utility model is by the following technical solutions:
Simply supported slab lift-up device on a kind of retaining wall, be included in the simply supported slab of transition between the place ahead cushion cap and the rear land-based area, establish retaining wall under the land side of simply supported slab, be provided with a plurality of jacking preformed holes at the top of retaining wall, between retaining wall and simply supported slab, also have lifting beam to be held on the described jacking preformed hole.
Preferably, between lifting beam, jacking preformed hole and rear land-based area, establish the retaining bank.
Preferably, the described retaining bank part that is retaining wall.
Further, also be provided with inspection manhole on the retaining wall, described manhole is arranged in the rear side of retaining wall.
Safeguard the construction period for shorten as far as possible, reduce the loss that stops production, on retaining wall, be provided with the jacking preformed hole, between retaining wall and simply supported slab, be provided with lifting beam, thereby when needs are adjusted the simply supported slab discrepancy in elevation, only need to use jack jacking lifting beam, can reach the purpose of jacking simply supported slab.The advantage of this structure is when safeguarding construction, does not need simply supported slab is opened, and only needs just connecing high retaining wall after the simply supported slab jacking, safeguards the duration thereby shorten greatly, reducing to minimum to the influence of producing.

The arrangement diagram of Fig. 3 jacking preformed hole.
Fig. 4 is the structure of retaining wall behind the jacking simply supported slab.
Fig. 5 is the vertical view that the part retaining wall of manhole is arranged.
The specific embodiment
See Fig. 1, adopt oblique top stake sheet pile cushion cap 1 as retaining soil with connect the bank structure, be connected to adapt to differential settlement with simply supported slab 3 between sheet pile cushion cap 1 and the land-based area 2.Retaining wall 4 is located at the below of simply supported slab 3 land sides one end, also is provided with lifting beam 5 between simply supported slab 3 and the retaining wall 4, and this lifting beam 5 is not fixedlyed connected with retaining wall 4, and lifting beam 5 length are general identical with retaining wall 4 section lengths, see Fig. 3.At retaining wall 4 tops a plurality of jacking preformed holes 41 are set, establish retaining bank 42 at the rear of lifting beam 5 and jacking preformed hole 41, to isolate lifting beam 5 and land-based area backfill, retaining bank 42 can be exactly the part that retaining wall 4 extends in the wings, sees Fig. 2.
When retaining wall 4 total lengths are long, personnel and equipment enter into simply supported slab 3 belows and carry out the jacking operation during for ease of jacking, also on the retaining wall 4 of part segmentation, be provided with inspection manhole 43 at a certain distance, see Fig. 5, inspection manhole 43 passes the wall body and arrives land-based area ground at the rear of retaining wall 4.
When needing jacking (adjusting simply supported slab 3 discrepancy in elevation), jack can be placed on jacking preformed hole 41 places, interlock jack stand lifting beam 5 is shelved concrete pad 6 (see figure 4)s on retaining wall 4, lifting beam 5 is on cushion block 6, thus jacking simply supported slab 3 land side laying ends.Jacking for convenience is provided with retaining bank 42 at lifting beam 5 rears, effectively isolated lifting beam 5 and backfill.
It is as follows that jacking preformed hole, lifting beam and structure Design main points thereof and construction process are set on the retaining wall:
A) according to the weight of top simply supported slab 3, estimate parameter and quantity that conditions such as settlement amount after construction are determined jack.
B) according to parameters such as the size of definite jacking preformed holes 41 such as the appearance and size of jack and stroke and positions.
C) determine the cross dimensions of the lifting beam 5 Xingqi structure design of going forward side by side according to the parameter of the weight of top simply supported slab 3, jack and spacing distance.
D) the design drawing construction is pressed by unit in charge of construction.
E) periodic observation retaining wall 4 sedimentations after construction is finished when the too big needs of the simply supported slab 3 two ends discrepancy in elevation are adjusted, are carried out the jacking operation.
F) by required top lifting height and quantity precast concrete cushion block 6.
G) personnel and equipment enter into simply supported slab 3 belows from inspection manhole 43, and jack is installed, and jack interlock jacking is shelved concrete pad 6 and fixing to required stroke on retaining wall 4, take off jack, and jack-up construction finishes.
