Except railing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model anti-freeze expansion intercepting ditch structure.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Refering to fig. 1, the utility model provides a kind of anti-freeze expansion intercepting ditch structure, can close anti-freeze expansion ditch and intercepting ditch two
One, making once to construct not only forms intercepting ditch, but also has carried out frozen prevention measures, solves the problems, such as that existing way is cumbersome.It ties below
Attached drawing is closed to be illustrated the utility model anti-freeze expansion intercepting ditch structure.
As shown in Figure 1, forming side slope 22 around foundation pit, it is provided with supporting construction in side slope 22, and top of the slope 23 is provided with
Guard rail 24.
The utility model anti-freeze expansion intercepting ditch structure includes: in the soil body 21 for being opened in foundation pit periphery and close to foundation pit
The irrigation canals and ditches 10 of supporting construction setting, the irrigation canals and ditches 10 are opened in top of the slope 23 around foundation pit and are located at except guard rail 24, irrigation canals and ditches 10
Depth be greater than or equal to frozen soil layer 211 depth, the frozen soil layer at supporting construction is separated by irrigation canals and ditches 10.Preferably,
The width of irrigation canals and ditches 10 is 300mm, and depth is consistent with the depth of frozen soil layer 211, and the setting of irrigation canals and ditches 10 is apart from 22 top of side slope
At edge 1500mm, wherein the distance between irrigation canals and ditches 10 and guard rail 24 are 500mm.
Wherein, it is filled with filler in irrigation canals and ditches 10 and forms buffer layer 11, buffer layer 11 is located in the soil of 10 two sides of irrigation canals and ditches
Between body 21, so that buffer layer 11 is squeezed after frost heave occurs for the soil body of frozen soil layer 211, so that frozen soil layer 211
The horizontal force that the soil body is applied to supporting construction reduces, and supporting construction is protected not to be damaged, and increases working security.Preferably, it fills out
It fills object and selects perlite, and the absolute altitude of 11 bottom of buffer layer is consistent with the absolute altitude of 211 bottom of frozen soil layer, makes the buffering of buffer layer 11
Effect reaches best.
It is equipped with bed course 12 on the buffer layer 11, is located on bed course 12 in irrigation canals and ditches 10 and forms space 13 of intercepting water, intercept water
Space 13 is in communication with the outside, and for intercepting the water flowed down from eminence, prevents water from flowing into construction area.And pass through 13 bottom of space of intercepting water
The bed course 12 in portion, the water in space 13 that prevents from intercepting water penetrate into the soil body 21 and cause body frost heaving serious, play preferable anti-freeze expansion
Effect.Preferably, the depth in space of intercepting water be 300mm, bed course 12 be C25 concrete layer, and bed course 12 with a thickness of 50mm.
Further, the width of bed course 12 is greater than the width of irrigation canals and ditches 10, and the outer rim of bed course 12 is embedded in the soil body 21, can be more
The water for preventing from well intercepting water in space 13 penetrates into the soil body 21, to enhance the antifreezing expansion effect of anti-freeze expansion intercepting ditch structure.Preferably
Ground, the width of bed course 12 are 500mm.
In a preferred embodiment, the top of the slope 23 between 22 edge of side slope and irrigation canals and ditches 10 has 3% gradient, and top of the slope
23 are higher than it close to the side of irrigation canals and ditches 10, so that the rainwater in Pluvial can converge into intercepting water for irrigation canals and ditches close to the side of side slope 22
In space 13, convenient for further rainwater is discharged by gutter.
