Description

Buoyancy type wetland sightseeing trestle

Technical Field

The utility model relates to a landing stage especially relates to a buoyancy formula wetland landing stage.

Background

The wetland is a transitional zone between a terrestrial ecosystem and an aquatic ecosystem, and a plurality of wetland aquatic plants grow in a specific environment in which soil is continuously immersed in water. The river flow type wetland is widely distributed in the middle and lower reaches of a great river, is an important ecological system in plain areas, has strong ecological purification effect, and is known as the lung of a city. Downstream wetlands in large and small rivers are generally distributed on two sides of a wide and shallow wandering river channel to form a special ecological landscape, and trestles built in the wetlands or along the river channels on two sides are most frequently used sight-seeing footpaths for pedestrians to approach nature and walk and visit. The trestle for tourists to walk at present generally has the following defects: 1. the trestle is fixed in height and position, and the bridge floor cannot change along with the change of the water level of the wetland; 2. the trestle is made of concrete or wood, and pedestrians cannot observe water bodies or aquatic animals and plants under feet; 3. when the river water level changes frequently, the bridge floor is far away from the surface of the water body in most of time, and the hydrophilicity is poor.

Detailed Description

As shown in figures 1-3, the buoyancy type wetland sightseeing trestle of the utility model comprises a bridge floor with floating blocks, a supporting beam 1 and a liftable pier,

the utility model discloses a pier includes that the lower part buries deeply in the ground and fixes a mound section of thick bamboo 2 (fixed mound section of thick bamboo 2 can adopt anticorrosive materials such as PVC or reinforced concrete, its bottom is blocked with concrete, bury deeply in the ground, keep the position motionless), sliding insert in fixed mound section of thick bamboo 2 and put the bridge pile 3 (bridge pile 3 is the bearing member, adopt reinforced concrete pipe or high strength polyvinyl chloride pipe, the smooth diameter of surface is slightly less than the internal diameter of fixed mound section of thick bamboo 2, be convenient for slide from top to bottom in fixed mound section of thick bamboo 2), it is provided with sealing ring 4 to lie in fixed mound section of thick bamboo 2 upper mouth edge department, the cross-section of sealing ring 4 is U-shaped groove structure, as shown in figure 4, the upper mouth edge of fixed mound section of thick bamboo 2 is interior book, the card is put; and a guide damping ring 5 is sleeved at the lower opening edge of the bridge pile 3.

For adapting to the water level change, the utility model discloses be cast structure with the design of bridge pile 3, be provided with the internal thread at its lower extreme, be equipped with holding ring 7 with the upper end cover of internal thread matched with adjusting screw 6, cross adjustment recess in its up end has been seted up.

When the fixed pier barrel 2 is filled with water, the rubber guide damping ring 5 and the rubber positioning ring 7 which are sleeved at the upper end of the adjusting screw 6 and are positioned at the lower opening of the bridge pile 3 act together to play a role in flow blocking and guiding, so that the left position and the right position of the bridge pile 3 can be controlled, the vertical moving speed of the bridge deck can be reduced, and the slow movement in lag can ensure that pedestrians walk on the bridge deck without discomfort caused by sudden increase of weight.

The bridge deck of the utility model is composed of strip plates 8 which are laid on a supporting beam 1 at intervals, and a floating block unit 9 is fixedly connected with the bottom of each strip plate 8. In actual manufacturing, the strip-shaped plate can be a transparent glass plate, a wood plate or a hollow plate (the width is generally 100-200 mm, and the thickness is 100-200 mm), and underwater animals and plants can be visually seen through a gap between the two plates or the transparent strip plate; the floating block unit 9 can be made of closed-cell rigid foam plastic, mainly comprising Polyurethane (PUR), Polystyrene (PS), polyvinyl chloride (PVC), Polyethylene (PE), phenolic resin (PF), etc., and has a density of 0.4-0.6kg/m³The compression strength meets the design requirements, and the product has the properties of light weight, corrosion resistance, moisture resistance, impact resistance and the like.

The supporting beam 1 of the utility model can be formed by connecting I-shaped steel or square steel flexibly in sequence, which is convenient for overcoming thermal expansion and cold contraction and construction; the plane line shape of the support beam 1 can be changed along with the river bank, and can be a broken line or an arc line, and the length is not limited.

For safety, the bridge deck is also provided with guardrails which can be composed of metal supporting rods 10 and transparent plates and have safety protection and visibility; in order to adjust the adjusting screw 6 conveniently, a through hole (hollow rod can be adopted for the supporting rod) corresponding to the adjusting screw 6 is arranged in the supporting rod corresponding to the position of the bridge pile 3, and a sealing cover 11 is arranged at the top of the supporting rod 10 in order to prevent sundries from falling into the through hole of the supporting rod to affect normal use.

The width of the bridge deck determines the number of rows of the bridge piles 3 under the bridge deck, if the bridge deck is narrow, the bridge piles 3 can be arranged in two rows, if the bridge deck is wide, the bridge piles 3 can be properly added in three rows or four rows, the width of the bridge deck is not limited, the bridge piles can be realized only by adding piers, and three rows of bridge piles are shown in fig. 5; when meeting a rest platform or a viewing platform, the number of the landing stage can be increased locally, and the use safety of the landing stage is met.

The working conditions can be used:

the working condition I is as follows: when the water level of the wetland is highest (the historical highest water level of the wetland is considered during design), the buoyancy is increased, the bridge floor is too high, the visual field of visitors is wide, the water under the bridge floor is deep, the number of animals and plants is increased, and the ornamental value is optimal;

working conditions are as follows: when the water level of the wetland is equal, the buoyancy is reduced, and the bridge floor is lowered;

working conditions are as follows: when the water level of the wetland is lowest, the buoyancy is minimum, the bridge deck is closest to the water surface, and even when surface water completely escapes, the trestle on the dry riverbed still keeps stable;

working conditions are as follows: if the requirement of stepping on waves exists, the volume of the floating block units is reduced at a proper bridge section, the bridge deck is controlled to be slightly lower than the surface of a water body (the height is controlled within 200mm generally), pedestrians feel water temperature while shaking slightly along with the waves, and the hydrophilicity and interestingness of playing are increased.
