Abstract

The invention discloses a frost heaving resistance device for an embankment project. The frost heaving resistance device comprises a sealing plate, the interior of the sealing plate is divided into at least four independent cavities through at least three supporting plates, and a steam generator is arranged at the bottom of the sealing plate. The side edge of a power assembly located at the right end of the steam generator is connected with an arc-shaped base plate through a waterproof piston. The left end of the steam generator is provided with a water inlet pipe, and an electromagnetic timing valve is arranged on the water inlet pipe. The upper end of the steam generator is connected with a steam conveying pipe, and steam conveying branch pipes identical with the independent cavities in number are arranged at the right end of the steam conveying pipe. The outer end of the sealing plate is painted with a layer of anti-freezing finishing coat. According to the frost heaving resistance device, by means of the double measures of heat generated by the underwater steam generator needing no manual power supplying and the anti-freezing finishing coat formed by scientific compatibility, freezing of a hydraulic construction structure in frost weather is well prevented, and the hydraulic construction is prevented from being damaged by frost heaving; in addition, the frost heaving resistance device is low in cost, small in power consumption and capable of being used for a long time.

Description

A kind of anti-freeze expansion device of dyke building

Technical field

The present invention relates to a kind of water conservancy protector, particularly relate to a kind of anti-freeze expansion device of dyke building, belong to hydraulic engineering technical field.

Background technology

Water conservancy dykes and dams are a kind of hydraulic engineerings of flood discharge of discharging water for dash, when the winter of northern severe cold, it is common occurrence that dyke building thing destroys by static ice pressure, causes leak dam break, gate of dyke building thing can not continue normal use, leaves huge potential safety hazard.

At present, prevent dyke building thing ice from bursting bad method more, as benzene plate method, namely lay one block of benzene plate with distortion at building upstream face and absorb static ice pressure because ice expansible band comes, but benzene plate all needs to change every year, cost of labor is higher; Another kind is bubble proof, namely below the water surface of building upstream face, pipeline is set up, non-icing water-band is formed by the submersible pump ejection water surface by heat of compression air or high water temperature, but the weak point of the method is: which can not change because of range of stage, and the water level in the general reservoir such as reservoir, rivers is all dissimilar, and manually can use and some changes occur according to rainy season or dry season, generally have the ground of water can freeze just now, therefore practical effect is unsatisfactory; In addition also have the mode of hot pipe ice-melting, namely in gate panel or gate slot, increase heat pipe anti-freezing device, utilize electric heating by ice melting, though effect is good, power consumption is comparatively large, and cost is higher.

Summary of the invention

The present invention is exactly for the problems referred to above, proposes a kind of anti-freeze expansion device of dyke building, and this anti-freeze expansion plant energy consumption is low, anti-icing swollen effective, and can Long-Time Service, and cost is also lower.

For reaching above-mentioned technical purpose, present invention employs a kind of anti-freeze expansion device of dyke building, comprise the sealing plate that is sealedly attached to hydraulic engineering obstructing surface, by at least three pieces of gripper shoes, sealing plate is divided at least four separate chamber in described sealing plate, obstructing surface bottom described sealing plate is provided with a steam generator, and the power assembly side of this steam generator right-hand member is connected with an arc substrate by an anti-water piston; Described steam generator left end is provided with the water inlet pipe that can be supplied to steam generator water source, and this water inlet pipe has been threaded an electromagnetism Timed valve; Described steam generator upper end is connected with a steam pipeline, and this steam pipeline wears the left end into being also positioned at each separate chamber in sealing plate simultaneously, and the steam Transportation that described steam pipeline right-hand member is arranged with quantity identical with separate chamber quantity is in charge of.

Further, described sealing plate outer end paint is provided with the antifreeze finish paint of one deck, and this antifreeze finish paint is made up of linear loop epoxy resins, pigment, antifreeze, auxiliary agent and thinner.

The present invention produces heat and the dual measure of antifreeze finish paint by scientific compatibility by the steam generator under water that need not manually power, well prevent water construction structure freezing at severe cold weather, avoid water construction to destroy because ice is swollen, and cost of the present invention is low, energy consumption is little, can Long-Time Service.

Accompanying drawing explanation

Shown in Fig. 1 is appearance assumption diagram of the present invention;

Wherein, 1, sealing plate; 2, gripper shoe; 3, separate chamber; 4, steam generator; 5, power assembly; 6, anti-water piston; 7, arc substrate; 8, water inlet pipe; 9, electromagnetism Timed valve; 10, steam pipeline; 11, steam Transportation is in charge of; 12, antifreeze finish paint.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.

As shown in Figure 1, a kind of anti-freeze expansion device of dyke building, comprise one and be sealedly attached to the sealing plate 1 of hydraulic engineering as the obstructing surface of water resources dam, large lock lock, by at least three pieces of gripper shoes 2, sealing plate 1 is divided at least four separate chamber 3 in sealing plate 1, obstructing surface bottom sealing plate 1 is provided with a steam generator 4, and power assembly 5 side of this steam generator 4 right-hand member is connected with an arc substrate 7 by an anti-water piston 6; Be provided with the water inlet pipe 8 that can be supplied to steam generator 4 water source at steam generator 4 left end, this water inlet pipe 8 has been threaded an electromagnetism Timed valve 9; A steam pipeline 10 is connected with in steam generator 4 upper end, this steam pipeline 10 wears the left end into being also positioned at each separate chamber 3 in sealing plate 1 simultaneously, and the steam Transportation being arranged with quantity identical with separate chamber 3 quantity at steam pipeline 10 right-hand member is in charge of 11.

In said structure of the present invention, arc substrate 7 is more crucial parts, and in the middle of actual use, this arc substrate 7 plays the anti-water piston 6 of promotion makes steam generator 4 do work and produce the important function of steam; Its principle is: arc substrate 7 produces a thrust by the flowing of periphery water, and this thrust is in anti-water piston 6, thus initiation steam generator 4 does work; The electromagnetism Timed valve 9 that water inlet pipe 8 is threaded can open and close in timing, is introduced in steam generator 4 by water by water inlet pipe 8, thus is supplied to the water source that steam generator produces steam; The vapours produced can be in charge of 11 by steam pipeline 10 and steam Transportation and be assigned to each separate chamber 3, and separate chamber 3 temperature is raised, thus it is swollen with ice to well prevent freezing of this region.

In the present invention, sealing plate 1 outer end paint is provided with the antifreeze finish paint 12 of one deck, this antifreeze finish paint 12 is made up of linear loop epoxy resins, pigment, antifreeze, auxiliary agent and thinner, in the present invention, preferred linear loop epoxy resins, pigment, antifreeze, ratio between auxiliary agent and dilution are 3 to 1 to 1 to 1 to 4.

Antifreeze finish paint 12 plays a part the auxiliary sealing plate 1 that prevents and freezes, and adds the vapours effect in upper sealing panel 1, prevents freezing of this region swollen with ice better.
