Abstract
It is used for rock foundation fracture belt across lid processing construction method the invention discloses one kind, completely decomposed and highly weathered rock are cleared up using machinery with being manually combined by way of in rock fracture band, and at least 1 meter is extended out in original be broken on the basis of bandwidth to both sides；Design below raft foundation bottom absolute altitude 2.0m concrete levelings, then reinforcing bar is laid on request at fracture belt more than levelling rear 2.0m depth, casting concrete, using being filled by the way of lid, the width that fracture belt extends to both sides can ensure the supporting surface across lid on more complete middle decayed rock.The present invention is handled fracture belt both sides solid rock using across lid, on the premise of foundation bearing capacity requirement is met, is enhanced the globality and stability of foundation, is simplified construction technology, saved cost.
Description
Technical field：
The present invention relates to technical field of buildings, particularly a kind of rock foundation fracture belt that is used for is across lid processing construction method.
Background technology：
As the development of china's economy, the particularly quickening of urbanization process, skyscraper is more and more, building ground is carried out
The processing on base basis, which is operated in, to seem in the work progress of whole engineering and is even more important.Rock foundation is good foundation,
But the rock foundation of some areas may have crack, when fracture width, which reaches, forms rock fracture band to a certain degree,
The problem of foundation deformation can not meet design requirement just occurs, with the increasing of building dead weight, triggers ground uneven
Sedimentation, is that construction quality hides some dangers for.
The content of the invention：
To solve problems, it is used for rock foundation fracture belt across lid processing construction method the invention provides one kind, is ensureing
On the premise of foundation bearing capacity, the globality and stability of foundation are enhanced, preferable economic benefit is obtained and society imitates
Benefit.
The technical solution adopted by the present invention is：
One kind is used for rock foundation fracture belt and handles construction method across lid, it is characterised in that：Comprise the following steps：
1）Unwrapping wire and technique check：Determine fracture belt position and absolute altitude, axle are carried out using measuring instrument position across lid to fracture belt
The position determination checked with raft foundation, the determination of line are accorded with across the thickness of slab of cover plate and its support width on the solid rock of both sides
Close and require；
2）Cleaning：Fracture belt is cleared up, using manually with being carried out by the way of mechanical work compound when fracture belt is cleared up, first with machinery
It will be dug under fracture belt to design raft foundation bottom absolute altitude -3.0m places, then manually to complete in the rock foundation of fracture belt both sides
Weathering and highly weathered rock are handled to design raft foundation bottom absolute altitude -4.0m places, on the basis of original fracture bandwidth
At least one meter is extended out to both sides, to ensure that supporting surface is supported on solid rock, ensured on the solid rock of fracture belt both sides
Rubble and the poor completely decomposed rock of bearing capacity are cleaned out；
3）Crack is levelling：Treat step 1）With 2）After the completion of, using concrete to the design raft foundation absolute altitude -2.0m of fracture belt with
Under h1 regions change to fill out and pour and levelling, complete concrete leveling layer；
4）Reinforcing bar colligation：Treat step 3）In fracture belt at concrete leveling layer intensity reach after construction requirement, then disconnected
Split and carry out laying reinforcing bar operation on request with h2 regions more than levelling rear -2.0m depth, flow is as follows：
Reinforcement location line → fortune reinforcing bar is played to using in position → colligation securing plate lower rebar → placement reinforced bar support → colligation
Portion's reinforcing bar → setting posting → steel corrosion quantity；
5）Concrete placings, maintenance：Treat step 4）Reinforcing steel bar laying operation after the completion of to reinforced bar engineering carry out concealment acceptance, it is qualified laggard
The concreting operation in h2 regions more than row fracture belt -2.0m depth, the mode that pours of concrete uses inclined plane delamination, one
The secondary mode to top pours and circulates propulsion, and every layer pours thickness control within 500mm, when pouring, be in next layer of coagulation
Poured before native initial set and smash last layer concrete, must not made to produce the cold seam of construction between levels, to keep well connecing raft, improve mixed
Coagulating the compactness of soil, and carrying out maintenance to the concrete in the step in time by the way of covering, insulation can complete across lid
Plate is poured.
2. a kind of rock foundation fracture belt that is used for according to claim 1 handles construction method across lid, its feature exists
In：
More than 1 meter is respectively extended out on the width of the fracture belt both sides, is dug under thickness direction（h1+100mm）+（h2+100mm）,
Wherein 100mm is concrete leveling thickness, and across cover plate supported on both sides is on solid rock, support width >=1000mm.
Compared with prior art, the beneficial effects of the present invention are：
It is convenient and quick construction of the present invention, cheap, provided for fracture belt dealing with foundation and facilitate feasible method；Using across
Lid（Reinforced concrete raft plate is crossed over）Processing engineering method is handled fracture belt both sides solid rock, is meeting foundation bearing capacity requirement
Under the premise of, enhance the globality and stability of foundation；Reinforce band size and Reinforcement Design rationally, economic effect is obvious；
Manual digging pile construction is avoided, based process difficulty is reduced.
Brief description of the drawings：
Fig. 1 is constructing structure schematic diagram of the invention.
Embodiment：
Below in conjunction with the accompanying drawings, the present invention is described in further detail by embodiment：
One kind is used for rock foundation fracture belt and handles construction method across lid, comprises the following steps：
1）Unwrapping wire and technique check：Determine the position of fracture belt 1 and using measuring instrument to across the lid position of fracture belt 1 carry out absolute altitude,
Position determination, thickness of slab of the determination across cover plate 4 and its support on both sides solid rock 3 checked with raft foundation 2 of axis
Width meets the requirements；
2）Cleaning：Fracture belt 1 is cleared up, using with being carried out by the way of mechanical work compound, machine is manually used first when fracture belt 1 is cleared up
Tool will be dug to design raft foundation 2 bottom absolute altitude -3.0m under fracture belt to be located, then manually in the both sides rock foundation of fracture belt 1
