Description

Cast-in-place retaining plate template reinforcing technology in high-side slope pile plate wall supporting structure

Technical Field

The invention relates to the technical field of unit glass curtain wall installation, in particular to a technology for reinforcing a cast-in-place retaining plate template in a high-slope pile plate wall supporting structure.

Background

In the house construction process, due to regional terrain, the project to be built is often positioned under the feet of mountain bodies, so that support structures such as lattice beams, anchor cables, anti-slide piles, soil retaining plates and the like are mostly adopted for high slope projects. And for the anti-slide pile and retaining plate supporting structure, reverse construction is mostly adopted, the anti-slide pile needs to be constructed in advance, then earth excavation is carried out, and the retaining plate is constructed step by step.

At present, a steel pipe scaffold is mostly erected for reinforcing a single-side template of a soil retaining plate, and then the template is reinforced by methods of drilling a ground anchor for reinforcement or welding a counter-pull screw on a pile foundation main rib for reinforcement and the like. The traditional construction method has the characteristics of needing to set up a complete scaffold, having multiple welding processes and the like, and has the defects of large input amount of manpower and material resources, long construction period and the like because the scaffold needs to be removed after the construction of the first-stage retaining plate is finished when the reverse construction method is adopted, and the conditions of slurry leakage, formwork expansion and the like are frequently caused because the reinforcing difficulty is higher for a pile plate wall supporting structure with an overhigh free end. Most of the surface layers of the retaining plates are not decorated, and the requirement on the later-stage forming quality is higher, so that how to select an effective reinforcing method in a single-side template reinforcing system is a technical problem which needs to be solved urgently.

step two: determining the construction height of each level of the retaining plate according to the actual field situation and the outside template matching scheme, clearing soil among piles and implanting reinforcing steel bars after earthwork is excavated to a specified elevation, installing a bottom template of the retaining plate according to the size among the piles and the thickness of the retaining plate, and arranging through holes on the bottom template according to the specification and the interval of longitudinal reinforcing steel bars of the retaining plate;

step three: after the first-stage retaining plate steel bar binding and the template reinforcing are finished, arranging a concrete pouring opening at the upper opening of the retaining plate, and pouring concrete;

step four: and after the construction of the first-stage retaining plate is completed, starting the construction of the next-stage retaining plate according to the operations of the first step, the second step and the third step.

As a supplement to the technical scheme, in the fourth step, the next-stage retaining plate is constructed, wherein the installation requirement of the outer side template is higher than that of the upper-stage retaining plate by not less than 20 cm.

As a supplement to the technical scheme, the reinforcing member consists of oppositely-pulling screw rods, butterfly cards and screw caps, the distance between the oppositely-pulling screw rods is not more than 500mm, and the distance between the screw rod at the bottommost part and the end part is 100mm, so that the top template is reinforced when the next-stage retaining plate is constructed.

As a supplement to the technical scheme, in the second step, longitudinal steel bars are implanted into the bottom template, and the longitudinal steel bars conveniently and longitudinally arranged can smoothly pass through the through holes to be connected with the next-stage soil retaining plate for construction.

Has the advantages that: the invention relates to a cast-in-place retaining plate template reinforcing technology in a high-side slope pile plate wall supporting structure, which has the following specific advantages:

1. the operation is simple, the reinforcing purpose is achieved by anchoring one end of the embedded steel bar, and the embedded steel bar can be used as a horizontal steel bar for connection, so that the soil retaining plate and the anti-slide pile are connected into an integral supporting structure;

2. according to the actual situation of the site and the specification and the size of the template, the step-by-step excavation construction height is selected, and the template loss and other material input amount are reduced;

3. through the pre-buried screw rod of higher level's fender apron, consolidate the top that the fender apron of subordinate, effectively solve the phenomenon that the fender apron top rises mould, wrong platform. The longitudinal steel bars can be effectively connected with the lower-level soil retaining plate to form a whole through the preformed holes of the bottom template;

4. the construction cycle is short, reduces the potential safety hazard that the aerial work produced, reduces to set up a large amount of scaffolds.
