Building structure in the present embodiment, can be building engineering structure or bridge etc. other public set Foundation construction structure is applied, as long as the basis of structure has discrepancy in elevation misconnection position, it is possible to carried out using the structure in embodiment 1 Construction.

It refer to shown in Fig. 7, specifically, the building structure in the present embodiment, from earth excavation to construction to same mark The construction method in high face is as follows：

The preparation of construction

1st, according to engineering construction feature and the particularity of structure, supporting scheme should be by be expounded through peer review after can be real Apply.

2nd, engineering data is collected to construction unit, survey ＆ design units, the local weather information of inquiry is done with reference to actual conditions Good Pluvial and emergency case emergency measure.

3rd, technical annotation in construction can be carried out with designing unit's scene verification construction drawing.It is fully understood by design document, construction The main purpose of drawing and arrangement and method for construction.Engineering technology director to professional section chief tell somebody what one's real intentions are requiring careful, complete, perfect, And concrete operations position, the quality requirement of key location are combined, key points for operation and points for attention etc. are particularly stated friendship Bottom, and workman is told somebody what one's real intentions are in detail.

4th, the transfer at control point is measured, permanent coordinate stake and level foundation pile are set, SURVEYING CONTROL NETWORK is set up, is constructed Positioning, setting-out work.

5th, various experiments and detection device are examined and determine and verified；The new technology for intending using, new material, new technology are entered Row experiment, inspection and technical appraisement.

6th, plant equipment, construction material are made adequate preparation needed for scene.

First stage excavates

1st, precipitation processing completes to be adapted to after earth excavation condition, through live line setting, checks after examination passes through.Carry out field Ground earth excavation.Earth excavation is divided into two benches construction, because main building and underground garage ground substrate absolute altitude are two different levels, So first stage earth excavation is to two layers of main building underground ground position.

2nd, constructed in strict accordance with earth excavation and foundation pit support plan.Dig native to being reserved during default basal surface substrate Side reserves the protective layer that thickness is 40cm-60cm before being excavated to the basal surface of first foundation 10, preferably 50cm treats CFG 11 and support pile 50 construct after the completion of cleared up again, in order to avoid destruction ground soil property.

3rd, earthwork layer and section is excavated, and earth excavation presses the steps of 2m mono-, after the completion of the first stage excavates, using anchor pole or soil Nail wall is reinforced to excavation slope.Shield is sprayed after progress next step earth excavation and bank protection after intensity permission.

4th, in order to grasp slope deforming dynamic in time, it is ensured that side slope safety is stable and engineering is smoothed out, need side slope and Neighboring buildings carry out deformation monitoring.Main side slope carries out horizontal displacement observation and neighboring buildings settlement observation.

CFG stakes 11 and support pile 50 are constructed

1st, foundation plan, CFG stakes 11 and the piling foundation plan of support pile 50 release control axis, while setting high program control in bottom land Point processed.Management is checked after examination passes through, and carries out CFG stakes 11 and support pile 50 is constructed, constructed using many rotary drilling rigs, root The working face provided according to earth excavation carries out segmental construction.

2nd, behind the complete lift-off ground of drilling rod, handful of vibrating is put into immediately and is vibrated, depth of vibrating should be greater than 3.0m.Stirring, pumping Or carry brill and want close coordination, it is to avoid broken pile caused by filling process.

3rd, it should protect and conserve in time after pile, strictly be protected into pile head, prevent heavy-duty machinery walking, perturb.

Second stage earth excavation

1st, after support pile 50 is with bar intensity of test block to normal intensity 75%, second stage earth excavation Guan Liang 51 can be carried out Construction.The construction beam top mark of Guan Liang 51 height reserves the thick cushion processing of 1m than the main building low 1m of ground absolute altitude.

2nd, after the intensity of Guan Liang 51 reaches 80%, earth excavation can be carried out.

3rd, the earthwork, which is opened, follows layer and section excavation, and each cutting depth must not exceed 2m, facilitate spray shield between piled anchor and stake to apply Work.

4th, in digging process, it is observed daily once；, should be upper and lower when such as finding that displacement is larger or has mutation Noon respectively observation 1 time；Concrete cushion pours backsight slope soil deformation proper extension observation cycle.Using anchoring piece 53 Guan Liang 51 and support pile 50 are reinforced, carrying out mattress layer 52 at the top of Guan Liang 51 constructs.

Underground garage end bay is constructed

1st, because of the garage located underground of support pile 50 and main building structure junction, and support pile 50 is under main building ground simultaneously tightly Basement wall body 21 is pasted, so support pile 50 is designed into the outboard template of garage wall 21 (such as brick loose tool).

2nd, the waterproof of support pile 50 is constructed using outer anti-interior patch method, and the template of wall 21 uses single side formwork technology.

3rd, list formwork is to reinforce to fix on form bracing system, draws screw rod, triatic stay, diagonal brace, reinforcement perpendicular using single Reinforced to keel.Implement measures to ensure that template possesses some strength support, template is kept necessarily using top pull pattern Perpendicularity.

4th, underground garage exterior wall uses single side formwork principle, and bolt is drawn using single, by template together with keel reinforcing, no Using screw rod through walls, wall 21 is without hole through walls, impermeable structure performance enhancement, it is ensured that the water resistance of underground engineering.

Structure integral construction

After the completion of end bay construction, the construction at misconnection position is carried out, first foundation 10 and the is used as using the side of supporting construction The exterior sheathing of wall 21 between two bases 20, basal surface, the basal surface and external mold on the second basis 20 to first foundation 10 Plate carries out concreting process, and specific construction procedure is：The raft slab muscle on the basis 20 of colligation first foundation 10 and second, is tied up The reinforcing bar of wall 21 pricked between the basis 20 of first foundation 10 and second, sets the inner template of wall 21, by the remote of support pile 50 Then the side of first foundation 10 pours the raft plate on the second basis 20, the raft plate of first foundation 10 and wall as exterior sheathing 21 concrete.

When underground garage is constructed to F3/B3 top, same absolute altitude is in main building ground, main building is provided simultaneously with raft plate and applied Work condition, reinforcing bar is carried out after colligation by design and code requirement, underground garage F3/B3 concrete roof and main building underground two Layer raft plate is poured simultaneously, so that main building is connected as a single entity with underground garage agent structure.

Main building can not influenceed with underground garage while constructed by excavation of foundation pit after agent structure is connected as a single entity, Also acceptor's floor foundation does not face the influence on side.

To complete the preparation that above-mentioned construction procedure also needs to carry out following aspects：Material and equipment, quality, safety, Environmental protection.
