Embedded flood barrier Hm4e-0012C

Short Description:

Product installation of automatic flood barrier

The model 600 can be installed on the surface or embedded. Models 900 and 1200 can only be installed in embedded system. The installation of flood barrier must be completed by a specially trained professional installation team, and shall be in accordance with schedule I (full automatic hydraulic power Flood gate – installation acceptance form) can be used only after passing the acceptance.

Note: if the installation surface is asphalt ground, because the asphalt ground is relatively soft, the bottom frame is easy to collapse after long-term rolling by vehicles; moreover, the expansion bolts on the asphalt ground are not firm and easy to loosen; therefore, the asphalt ground needs to be rebuilt with concrete installation platform as required.

Embedded Installation of automatic flood barrier

(1) Embedded installation slot position:

a) It should be set behind the outermost intercepting ditch. Reasons: small water can be discharged through the intercepting ditch; when flood occurs, the municipal pipeline will be backfilled from the intercepting ditch when the water is full.

b) The higher the installation position, the higher the water retaining level.

(2) Discharge capacity of residual water in the installation tank:

a) A 50 * 150 water collecting tank is reserved at the bottom of the installation slot, and a Φ 100 drainage pipe is reserved at the bottom of the water collecting tank.

b) Discharge test: after pouring some water, the water can be discharged smoothly from the drain pipe.

(3) The levelness of the installation surface:

The installation surface horizontal height difference of the two sides should be ≤ 30mm (measured by laser level meter)

(4) The flatness of the installation surface:

According to the quality acceptance code of construction ground engineering GB 50209-2010, the surface flatness deviation should be ≤2mm ( applied 2m guiding ruler and wedge feeler gauge). Otherwise, the ground should be leveled first, or the bottom framework will leak after installation.

(5) Installation surface strength

a) The installation surface is made of at least C20 concrete with thickness ≥Y and the surrounding horizontal extension X ≥300mm or using equivalent strength of installation surface.

b) The installation surface should be free of cracks, hollowing, falling off , etc. The concrete should be qualified for the quality acceptance code of concrete structure engineering GB50204-2015, otherwise, need remade concrete installation surface according to the requirement.

c) In case of concrete, it should beyond curing period.

(6) Side walls

a) Side wall height should be higher than the flood barrier, otherwise it should be created.

b) The side walls should be made of solid brick or concrete or equivalent installation surface. If the wall is of metal or nonmetal material, relevant reinforcement should be applied.
