Background technology

Understand according to the applicant, existing retaining wall deadweight is heavier, and narrow application range can not be used on the special soil properties such as soft soil, mucky soil, expansive soil, can not adapt to foundation settlement or of short duration unconventional load (as sudden drawdown, collision, earthquake etc.) on a small scale; Material therefor is difficult to permeable, and not only body of wall ruptures easily, and is unfavorable for ecological, environmental protective; The body of wall volume is big, materials are many, and cost is higher; Construction speed is slow, and the duration is longer; It is bigger that quality is influenced by human factor, and quality controllability is poor.

The utility model content

The purpose of this utility model is: the problem at above-mentioned prior art exists, a kind of self-locking dust block is proposed, and the body of wall that the base is built is applied widely, possesses the permeable native function of staying, and construction speed is fast, and quality controllability is good.

In order to reach above purpose, a kind of self-locking dust block of the present utility model comprises that cross section is trapezoidal main body block, and an end of described main body block broad extends the broadening eaves to both sides; Its improvements are: the end face at described main body block broadening eaves place is provided with horizontal arc fin, and the bottom surface is provided with the transverse arc connected in star that is complementary with described arc fin; The middle part of described main body block is provided with the through hole that runs through described end face and bottom surface.

The utility model further improves, described arc groove be positioned at described arc fin under.

It is that described arc groove is positioned at the front lower place of described arc fin that the utility model further improves.

It is that the termination of described broadening eaves is curved that the utility model further improves.

It is that the two sides, rear portion of described main block are the plane that the utility model further improves again.

The utility model dust block is built and is built when forming body of wall, and the arc groove of arc fin on lower floor's dust block and dust block bottom surface, upper strata is complementary with the locking dust block; But with the left and right sides translation under the cooperation of arc fin groove of one deck block, reserve the space of engine request, make things convenient for green grass and pipeline embedding; Can build as required and build up erect type or apsacline body of wall; In through hole and between the dust block, add and fill out graded broken stone, can increase the frictional force between block, and strengthen the body of wall drainability; The termination of broadening eaves is curved, can make body of wall form any radian, satisfies requirement of engineering.

The utility model dust block has unique technical construction, can build according to requirement of engineering to build up various special designs; Simultaneously, lighter because of building the deadweight of walling body, can be widely used in special soil properties such as soft soil, mucky soil, expansive soil, be applicable to multiple building and various job practices.

The utility model dust block is built the body of wall of building and be may be seated on bar shaped concrete or the flexible aggregate basis, and whole body of wall is a flexible structure, and small-scale foundation settlement or of short duration unconventional load (as sudden drawdown, collision, earthquake etc.) are had high-adaptability; This body of wall volume is little, materials are economized, and can significantly reduce cost.

The utility model dust block is built the body of wall build and is had the permeable native function of staying, and promptly the soil body behind water and the wall can effectively carry out the water and soil circulation, makes water body can reach the purpose of self purification; Nutrient rich mass-energy in the water body progressively precipitates at the body of wall periphery, and the space in the body of wall helps constructing the water ecology circulating system for aquatic animals and plants and various microorganism provide a good place of staying in.

The utility model dust block is drystone directly, can significantly improve construction speed, effectively the reduction of erection time; In addition, this dust block is to form by the mechanized equipment compacting in factory, and the block quality is influenced by human factor hardly, and quality controllability is good, thereby guarantees the monolithic stability of workmanship.
