Abstract
The utility model discloses a take gate structure of novel air vent, including concrete bottom plate, manger plate breastwork and bulky concrete, the gate is installed through the gate groove in concrete bottom plate top, the gate is located manger plate breastwork rear portion, the manger plate breastwork forms the gate maintenance space that is located the gate top with bulky concrete, the gate rear is through air vent and gate maintenance space intercommunication, and the air vent is the type of falling L structure, the air vent overhauls space intercommunication department with the gate and installs safety grid, the gate top still is provided with overhauls the platform, it is provided with the protection railing to overhaul the platform periphery. The utility model discloses a set up the type of falling L air vent and communicate gate and gate maintenance space, prevent that the traditional air vent that directly stands up and down from causing the structure top to appear the quick air current, avoid influencing dam and water inlet top overall arrangement problem; meanwhile, the problem that the whole traffic of the top is influenced due to the fact that the whole arrangement difficulty of the top is increased due to too many holes is avoided.
Description
Technical field
The utility model belongs to the water conservancy project technical field in hydraulic engineering, specifically relates to a kind of gate structure with New type ventilating hole.
Background technology
Air vent, as common universal architecture a kind of in hydraulic structure, is usually placed in the rear runner of the gate such as dam, water inlet.In the process that diversion culvert carries out water-filling or emptying, need exhaust and tonifying Qi after gate, particularly during dynamic door under water, problem is more outstanding, otherwise can cause pressure pipeline parital vacuum and stand negative pressure, even can cause pipeline and gate flap vibration.For this reason, after adjacent gate, air vent must be set.But traditional steam vent is direct communication channel dam or water inlet top from the below of runner normally, and then arranges grid cover plate and guard rail at top.When air vent tonifying Qi or exhaust, the air vent at dam crest, water inlet top has fast gas flowing.Meanwhile, due to general dam body and water inlet top layout compact conformation, perforate too much strengthens topside perspective and arranges difficulty, affects topside perspective traffic.
Utility model content
For solving the problem, the utility model provides a kind of gate structure with New type ventilating hole.Thus cause top to occur the problem that fast gas flows when solving pore exhaust, tonifying Qi.
The utility model is achieved by following technical solution.
A kind of gate structure with New type ventilating hole, comprise concrete floor, dash breastwork and concrete in mass, by gate slot, gate is installed above described concrete floor, described gate is positioned at dash breastwork rear portion, described dash breastwork and concrete in mass form the gate space for maintenance be positioned at above gate, described gate rear to be communicated with gate space for maintenance by air vent be exhausted, tonifying Qi, and air vent is inverted L shape structure.
Described air vent and gate space for maintenance connectivity part are provided with safety grids 8.
Also inspection platform is provided with above described gate.
Described inspection platform periphery is provided with guard rail.
The beneficial effects of the utility model are:
Compared with prior art, gate is communicated with gate space for maintenance by arranging inverted L shape air vent by the utility model, prevent conventional ventilation hole straight up and down from causing structural top to occur quick flow, avoid affecting dam and water inlet topside perspective Layout Problem, simplify hydro-structure integral arrangement; Avoid perforate too much to strengthen topside perspective simultaneously and arrange difficulty, affect topside perspective traffic, accelerating construction progress, greatly improve efficiency of construction.
Accompanying drawing explanation
Fig. 1 is the utility model section structure schematic diagram.
In figure: 1-concrete floor, 2-gate, 3-gate slot, 4-dash breastwork, 5-gate space for maintenance, 6-concrete in mass, 7-air vent, 8-safety grids, 9-inspection platform, 10-guard rail.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of gate structure with New type ventilating hole described in the utility model, comprise concrete floor 1, dash breastwork 4 and concrete in mass 6, by gate slot 3, gate 2 is installed above described concrete floor 1, described gate 2 is positioned at dash breastwork 4 rear portion, described dash breastwork 4 forms with concrete in mass 6 the gate space for maintenance 5 be positioned at above gate 2, described gate 2 rear to be communicated with gate space for maintenance 5 by air vent 7 be exhausted, tonifying Qi, and air vent 7 is inverted L shape structure.Adopt the technical program, solve conventional ventilation hole and lead directly to dam crest, water inlet top, fast gas flows to cause top to occur when air vent exhaust, tonifying Qi; Simultaneously dam crest, water inlet top drilling too much cause the problem of topside perspective difficult arrangement.
Described air vent 7 is provided with safety grids 8 with gate space for maintenance 5 connectivity part.Prevent aerial dirt or animal from entering in air vent 7.
Inspection platform 9 is also provided with above described gate 2.
Described inspection platform 9 periphery is provided with guard rail 10.
In practice of construction, the horizontal segment height of described inverted L shape air vent is higher than front more than peak level 1m.
