The Chinese patent application 'double-cavity rubber dam bag' (application number: 201910407519.4, published as 2019.8.16) discloses a double-cavity rubber dam bag, which comprises a water-retaining rubber dam bag arranged on the upstream side and a supporting rubber dam bag arranged on the downstream side, wherein the water-retaining rubber dam bag and the supporting rubber dam bag are respectively filled with water or air, the water-retaining rubber dam bag and the supporting rubber dam bag are arranged in a mutual extrusion manner, the water-retaining rubber dam bag can be obliquely pressed on the supporting rubber dam bag on the downstream side in the opposite direction under the action of hydrostatic pressure, and the bottoms of the water-retaining rubber dam bag and the supporting rubber dam bag are fixed on a foundation through anchoring pieces.
However, the bottom of the dam bag is fixed on a foundation through the anchoring piece, so that the dam bag is difficult to construct, long in installation time, only used in fixed occasions and not suitable for occasions needing temporary and quick water retaining facilities such as underground engineering, roads and the like.
Disclosure of Invention
An object of the utility model is to provide a portable two-chamber manger plate dam, the construction simple installation is convenient for set up fast.
Realize the utility model discloses the technical solution of purpose does:
the utility model provides a portable two-chamber retaining dam, is including setting up retaining dam bag 1 at the upstream face and setting up the support dam bag 2 at the surface of a river, support dam bag 2 front portion through connecting band 3 and retaining dam bag 1 rear portion flexible fixed connection, still include anterior can with 5 laminating of ground, rear end and retaining dam bag 1 sealing connection's ground mat 4.
Preferably, the floor mat 4 comprises a flexible backing plate 43, and a transverse pressing strip 41 is arranged at the front end of the backing plate 43.
Compared with the prior art, the utility model, it is showing the advantage and is:
the construction and installation are simple and convenient: the utility model discloses make full use of ground mat 4 and 5 laminating on ground utilize flood self weight to compress tightly the manger plate dam. The higher the water level is, the larger the pressure is, the self-adaptive fixation of the retaining dam and the ground 5 is realized, the construction and installation are simple and convenient, and the rapid setting is convenient. The device is suitable for occasions needing temporary and quick water retaining facilities such as underground engineering, roads and the like.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Drawings
Fig. 1 is a schematic structural view of the movable double-cavity retaining dam of the present invention.
In the figure, a dam bag 1, a supporting dam bag 2, a dam bag filling inlet 11, a supporting dam bag filling inlet 21, a dam bag outlet 12, a supporting dam bag outlet 22, a connecting belt 3, a ground mat 4 and a ground 5.
Detailed Description
As shown in fig. 1, the utility model discloses portable two-chamber retaining dam, including setting up retaining dam bag 1 at the upstream face and setting up the support dam bag 2 at the dorsal face, support dam bag 2 front portion through connecting band 3 and retaining dam bag 1 rear portion flexible fixed connection, still include anterior ground mat 4 that can laminate with 5 on ground, rear end and retaining dam bag 1 sealing connection.
Preferably, the retaining dam bag 1 and the supporting dam bag 2 are in a shape of a horizontal cylinder after being filled with air or water.
The upper part of one end of the dam bag 1 is provided with a dam bag charging port 11 for charging air or water, and the upper part of the other end is provided with a dam bag discharging port 12 for exhausting air or discharging water.
The upper part of one end of the supporting dam bag 2 is provided with a supporting dam bag charging port 21 for charging air or water, and the upper part of the other end is provided with a supporting dam bag discharging port 22 for exhausting or discharging water.
When the flood comes, the ground mats 4 of the movable double-cavity retaining dam are flatly laid on the ground 5, air is respectively filled in the retaining dam bags 1 and the supporting dam bags 2, the flood flows over the ground mats 4, and the retaining dam bags 1 retain the flood; the ground mat 4 is anchored on the ground 5 by flood, and the ground mat 4 prevents the dam bag 1 from being washed away by water; the supporting dam bag 2 supports the retaining dam bag 1 and prevents the retaining dam bag 1 from rotating upwards.
As the flood level rises, the water pump is adopted to fill the blocked flood into the water retaining dam bag 1 and the supporting dam bag 2 to replace the original air. The dam bag 1 and the supporting dam bag 2 generate larger friction force with the ground due to the action of water pressure in the dam body, the capability of resisting flood impact is enhanced, and the water retaining height is increased.
The utility model discloses make full use of ground mat 4 and 5 laminating on ground utilize flood self weight to compress tightly the manger plate dam. The water level is higher, and pressure is big more, realizes the utility model discloses manger plate dam is fixed with 5's on the ground self-adaptation, and the construction simple installation is convenient for set up fast. The device is suitable for occasions needing temporary and quick water retaining facilities such as underground engineering, roads and the like.
As a modification, the floor mat 4 comprises a flexible backing plate 43, and a transverse pressing strip 41 is arranged at the front end of the backing plate 43.
The pressing strips 41 and 44 are arranged at the front end of the backing plate 43 and even on the two sides of the front part, and the pressing strips are made of solid materials with specific gravity far greater than that of water, such as iron blocks and aluminum blocks, so that the floor mat 4 can be prevented from being flushed by water and floating at the initial water blocking stage, and the attaching tightness of the floor mat 4 and the ground 5 is influenced. Therefore, the device can be fixed on the ground by utilizing water pressure more easily, and the water retaining function of the device is realized.
A plurality of drainage ditches 42 are longitudinally arranged on the lower surface of the rear part of the backing plate 43.
Set up longitudinal drainage ditch 42 at backing plate 43 rear portion lower surface, can in time drain away the remaining water on ground or the water of infiltration through backing plate 43 front end or both sides when this device initial stage installation, avoid producing between ground mat 4 and the ground 5 and slide because of having the remaining water to improve ground mat 4's pressure anchor effect more.
