The utility model solves the arch dam table hole gate pier crossbeam that its technical problem adopts, comprise table hole, gate pier and crossbeam, described crossbeam is arranged on described gate pier, described crossbeam comprises multiple crossbeam section, also comprise wide crack structure and backfill grouting body, described wide crack structure is arranged on described gate pier, and described backfill grouting body is cast in described wide crack structure.
Be further, described wide crack structure comprises and flows to wide seam and horizontal wide seam, described upstream face and the downstream face flowing to wide seam and run through described crossbeam, the wide seam of described transverse direction is from the upstream face of described crossbeam along described gate pier Yokogawa to layout, and described crossbeam section is arranged between adjacent described wide crack structure.
Further, describedly flow to wide seam and flow to layout downstream along the gate pier center line of described gate pier.
Further, the wide crack structure of both sides, described table hole is arranged symmetrically with along table centerline hole in the horizontal plane.
Further, the wide seam of described transverse direction be positioned on middle described gate pier runs through described gate pier, is positioned at the wide seam of described transverse direction on the described gate pier at two ends and extends from the upstream face of described crossbeam and describedly flow to wide seam along connecing.
Further, the described seam flowing to wide seam and horizontal wide seam is wide is not less than 1 meter.
The beneficial effects of the utility model are: flow to wide seam and horizontal wide seam owing to being provided with on the gate pier of arch dam table hole, by table hole crossbeam along arch ring with the wide seam of gate pier for boundary is divided into some sections, can build each crossbeam section respectively, the later stage wide seam intersegmental to crossbeam backfills, ensure that each crossbeam section connects into entirety, meet its power transmission requirement, reduce concreting ability, the requirement of temperature control capacity, manpower and materials are saved, decrease the possibility of concrete cracking, solve the problem that arch dam table hole crossbeam concrete in mass can not lead to storehouse continuous placing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.It should be noted that at this, the explanation for these embodiments understands the utility model for helping, but does not form restriction of the present utility model.
As shown in Figure 1 to Figure 3, the utility model comprises table hole 1, gate pier 2 and crossbeam 3, and described crossbeam 3 is arranged on described gate pier 2, and described crossbeam 3 comprises multiple crossbeam section 31, also comprises wide crack structure 4 and backfill grouting body; Described wide crack structure 4 is arranged on described gate pier 2, preferably, described wide crack structure 4 comprise flow to downstream arrange flow to wide seam 41 and from the upstream face 5 of described crossbeam 3 along described gate pier 2 Yokogawa to the wide seam 42 of transverse direction arranged, described upstream face 5 and the downstream face 6 flowing to wide seam 41 and run through described crossbeam 3, described crossbeam section 31 is arranged between adjacent described wide crack structure 4; Described backfill grouting body is cast in described wide crack structure 4.The gate pier 2 of arch dam is higher than the part of close downstream face in the part near upstream face, forms hierarchic structure.Therefore, arrange above gate pier 2 flow to wide seam 41 and laterally wide seam 42 crossbeam section 31 and gate pier 2 can be departed from completely, each crossbeam section 31 of convenient cast.During enforcement, by crossbeam 3 along arch ring with the wide crack structure 4 above gate pier 2 for boundary is divided into some sections, first build each crossbeam section 31 respectively, the later stage backfills with backfill grouting body the wide crack structure 4 between crossbeam section 31, ensures that each crossbeam section 31 connects into entirety.After wide crack structure 4 is established for crossbeam 3, reduce the requirement to concreting ability, temperature control capacity, saved manpower and materials, decrease the possibility of concrete cracking.
Specifically, the stability of structure during in order to ensure to pour into a mould crossbeam section 31, describedly flows to wide seam 41 and flows to layout downstream along the gate pier center line 21 of described gate pier 2; The wide crack structure 4 of both sides, described table hole 1 is arranged symmetrically with along table centerline hole 11 in the horizontal plane.Wide seam 41 will be flowed to arrange along gate pier center line 21, can to make on every gate pier 2 suffered to come from the uniform distribution of adjacent two crossbeam section 31 gravitational loads, simultaneously, wide crack structure 4 is arranged symmetrically with along table centerline hole 11 in the horizontal plane, the two ends of each crossbeam section 31 can be made to lay respectively on adjacent two gate piers 2, the gravity of a crossbeam section 31 is distributed to adjacent two gate piers 2, make the load of bearing of each gate pier 2 reduce and be evenly distributed.
Specifically, in order to make crossbeam section 31 and gate pier 2 to be separated during cast crossbeam section 31, facilitate and follow-up backfill grouting is carried out to wide crack structure 4, the wide seam of described transverse direction 42 be positioned on middle described gate pier 2 runs through described gate pier 2, is positioned at the wide seam of described transverse direction 42 on the described gate pier 2 at two ends and extends from the upstream face 5 of described crossbeam 3 and describedly flow to wide seam 41 along connecing.
Specifically, conveniently carry out backfill grouting process to wide crack structure 4, the described seam flowing to wide seam 41 and horizontal wide seam 42 is wide is not less than 1 meter, with meet the later stage wide crack structure 4 is built time necessity operating space needs.To be done to each crossbeam section 31 build and bottom arch ring joint grouting after, carry out backfill and the grouting of wide crack structure 4, ensure crossbeam 3 connect into entirety.
