Abstract
The utility model discloses an underground continuous wall display structure which comprises a groove section, wherein the groove section includes a steel cage, a gantry is mounted on the top of the groove section, and a funnel and a pipe connected with the funnel are mounted on the gantry. The underground continuous wall display structure has the advantages that construction quality of steel meshes of guide wall is detected on-site with corresponding devices, perceptual awareness is enhanced, safeguard measures such as up-down positional relation, steel specifications, spacing of steel bars and thickness of protective layers of the steel meshes are observed and measured, overall sizes of the guide wall, such as length and width, can be detected, and concrete quality of the guide wall can also be detected with devices. Understanding of guide wall drawings and construction techniques is deepened by detecting the construction quality on-site, and students can grasp construction features of the underground continuous wall steel cage quickly by comparing on-site constructions with drawings.
Description
Technical field
The utility model relates to a kind of display structure, and more specifically, it relates to a kind of diaphragm wall display structure.
Background technology
Diaphragm wall is the pattern foundation pit supporting structure form that the high-rise building foundation excavation adopts often, it is with special trench machine, the groove of a unit groove section of excavation under mud off, put into reinforcing cage at clear the end, with the tremie placing concrete to design elevation, a unit groove construction is complete, and each unit groove is intersegmental to be connected by special joint, forms continuous reinforced concrete wall.Diaphragm wall can be used as supporting and protection structure, but not only can keep off soil but also dash, also can be also used as the load-carrying members of building simultaneously.Because continuous underground wall structure is complicated, seldom adopt in common engineering, only just use in major works adopt, so do not have the experience directly perceived of this pattern foundation pit supporting structure in many people's life experience, sciolistic many especially to the construction technology links.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, intuitively diaphragm wall display structure clearly.
The purpose of this utility model is achieved through the following technical solutions.This diaphragm wall display structure comprises the groove section, and described groove section comprises reinforcing cage, is provided with portal frame, the conduit that described portal frame is provided with funnel and is connected on groove section top.
As preferably: described funnel and conduit are two pairs.
As preferably: described groove section begins from groove section bottom, is provided with concrete.
The beneficial effects of the utility model are: can carry out the understanding that field test operates to strengthen perception to the construction quality of the reinforced mesh of leading wall by utilizing corresponding instrument, as watching and measuring contents such as the upper-lower position relation of reinforcing bar in reinforced mesh, bar gauge, rebar spacing, protective layer thickness safeguard measures; Also can be to the detection of the length and width of leading the wall overall dimension and thickness etc.; Also can adopt instrument that the concrete quality of leading wall is detected.Deepen leading the understanding of wall drawing and construction technology by above construction quality field test.The student by at the scene with the contrast of drawing, can grasp relatively rapidly the construction features of diaphragm wall reinforcing cage.
Description of drawings
Fig. 1 is the utility model structural representation;
Description of reference numerals: reinforcing cage 1, funnel 2, portal frame 3, groove section top 4, groove section bottom 5, concrete 6, mud 7, conduit 8, build diaphragm wall 9.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model is described in connection with preferred embodiment, should know, do not represent that the utility model is limited in described embodiment.On the contrary, the utility model will be contained alternative, modified and the equivalent in the scope of the present utility model that can be included in attached claims restriction.
As shown in Figure 1, the diaphragm wall display structure comprises the groove section, and described groove section comprises reinforcing cage 1, is provided with portal frame 3, the conduit 8 that described portal frame 3 is provided with funnel 2 and is connected on groove section top 4.Described funnel 2 and conduit 8 are two pairs.Described groove section is provided with concrete 6 from groove section 5 beginnings of bottom.The groove section is adjacent for building diaphragm wall 9.
Conduit 8 wall thickness should not be less than 3mm, and diameter is preferably 200～250mm.The diameter manufacturing deviation must not surpass 2mm.Conduit 8 must be straight, sealing, mounting or dismounting are convenient.Conduit 8 total lengths should add the slotted eye lifting height greater than groove depth.The merogenesis length of conduit 8 should be determined by technological requirement.Between two pipes, available flange socket, wire rope handling joint or the button snap joint of two screw thread side connect, and conduit 8 length should not be less than 4m.The water proof bolt of concrete perfusion should be made with materials such as precast concrete plug, steel plate plug, foamed plastics.When using simultaneously 8 perfusion of two conduits in a groove section, its spacing should be greater than 3m, conduit 8 should not be greater than 1.5m apart from groove section termination, concrete surface should evenly rise, the discrepancy in elevation of the concrete surface at each conduit 8 places should not be greater than 0.3m, concrete should pour into complete before final set, and whole pouring concrete face elevation should be higher than designing requirement 0.5m.Filling process middle slot section mouth should be established cover plate, the groove internal contamination mud in order to avoid concrete is scattered; The mud that the cements out sedimentation basin of should making a gift to someone is processed, and must not allow mud overflow ground.Can not the directly waste treatment of reusable mud.
Pouring underwater concrete should be observed following requirement:
When 1) beginning to pour into, the position that the water proof bolt hangs should be close to the water surface, and the conduit 8 bottoms distance at the bottom of the hole should be advisable can discharge smoothly the water proof bolt, is generally 0.3～0.5m.
2) open to have in storage bin hopper before filling with and be enough to the disposable concrete storage capacity of imbedding the above degree of depth of 0.8m in underwater concrete in the bottom of conduit 8.
3) along with concrete rising, promote in good time and dismantle conduit 8, the following general 2～4m of maintenance of people's concrete surface is buried in conduit 8 bottoms, should not be greater than 6m, and must not less than lm, forbid conduit 8 bottoms proposition concrete surfaces.
4) under water in the filling concrete process, should there be the special messenger to measure conduit 8 buried depth and the outer concrete surface height of pipe, conduit 8 inner concrete face height of every 2h measurement in every 30 minutes.Concrete answers continous pouring to interrupt, must not traversing conduit 8, and should avoid touching when promoting conduit 8 and hang reinforcing cage 1.
