Abstract
A pre-stress pipe pile composite retaining wall structure which is used in civil construction is formed by compositing prefab pre-stress pipe piles and mixture. The retaining wall comprises prefab pre-stress pipe piles (1), and the mixture (2); the mixture (2) is disposed between prefab pre-stress pipe piles disposed side by side and in the pipe cores to connect adjacent prefab pre-stress pipe piles (1) integrally and form a front row composite retaining wall plate (A). An intensity adjusting retainer (B) composed of prefab pre-stress pipe piles (1) and mixture (2) disposed in the prefab pre-stress pipe piles (1) is disposed at the outer side of the composite retaining wall plate (A) which is connected with the intensity adjusting retainer (B) by a coping (3). The mixture material is formed by mixing cement, expansive soil, coal ash and soil body, thereby diameters of the pile pipes can be further contracted, and intensity of the retaining structure can be adjusted flexibly and conveniently.The invention relates to a filling earth quick hit-solid control method comprises following steps: performing a light hit-solid test to the filling earth, determining a linear regression equation of the optimal moisture percentage and the wet density at the optimal attitude according to the obtained relationship between the optimal moisture percentage and the wet density at the optimal attitude; inputting parameters of the linear regression equation into computer control system program, obtaining a quick hit-solid control system representing filling earth property, detecting wet density on site of the filling earth on site, cutting the earth and screening same with a 20 mm screen, dividing the screened earth into three parts, preparing earth samples with three different moisture percentage, performing a standard hit-solid test to obtain three hit-solid wet density.
Description
Technical field
The utility model structure is a kind of supporting and protection structure that is used for civil construction.Especially the composite supporting wall structure that the compound back of a kind of prefabricated prestressing pipe pile and stirring body forms.
Background technology
The prefabricated tubular pile composite support wallboard (patent No. 200620125443.4) of my application, have that support rigidity is big, economic and reliable, easy construction, retaining soil, plurality of advantages such as unite two into one, occupied ground is little blocks water, but, because pile tube is prefabricated units, it is not very flexible that the strength and stiffness of supporting wallboard are regulated.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of prefabricated prestressing pipe pile composite supporting structure, thereby the diameter of pile tube can further be dwindled, and it is flexible, convenient that supporting and protection structure intensity is regulated.
Technical scheme: prefabricated prestressing pipe pile composite supporting wall structure of the present utility model comprises prefabricated prestressing pipe pile, stirring body; Stirring body is between prefabricated prestressing pipe pile side by side and in the tube core, adjacent prefabricated prestressing pipe pile is connected as a single entity, form front-seat composite support wallboard, there is intensity to regulate supporting in the outside of composite support wallboard, intensity is regulated supporting and is comprised prefabricated prestressing pipe pile and be arranged in the prefabricated prestressing pipe pile tube core and pile tube stirring body composition on every side that composite supporting wall is regulated supporting with intensity and is connected by bent cap.The stirring body material stirs the back by cement, expansive soil, flyash and the soil body and forms.
Intensity adjusting supporting and front-seat supporting wallboard are different, and its stirring body can be discontinuous, even stirring body can be cancelled, and directly pile tube is pressed in the soil.The effect of bent cap is that supporting wallboard and intensity adjusting supporting are fused, it is the reinforced concrete cast-in-situ member, its preparation method of prefabricated prestressing pipe pile composite supporting wall structure is to adopt the deep-mixed pile machine that the soil body is stirred, mix admixtures such as cement, swell soil simultaneously, the soil body and admixture have formed stirring body after stirring; Before the stirring body knot is hard, prefabricated tubular pile is pressed in (or squeezing into) stirring body, when not having stirring body in the intensity adjusting supporting, can directly be pressed into pile tube in advance in (or squeezing into) soil, after front-seat supporting wallboard and intensity are regulated supporting and are finished, the bent cap of promptly constructing is regulated supporting with front-seat supporting wallboard and intensity and is connected as a single entity.Thereby form prefabricated prestressing pipe pile supporting and protection structure.
Beneficial effect: pile tube can batch production production, speed of production is fast, the concrete strength height, pile quality is reliable, there are prestressing force, rigidity big, after sinking to stirring body, pile tube relies on the stirring body be filled in (between pile tube and the pile tube and in the tube core) around the pile tube, adjacent pile tube is linked to be an integral body, formed front-seat composite support wallboard,, made supporting and protection structure regulate flexibly again because of there being intensity to regulate supporting, intensity adjusting supporting adjustable range is big, can be adjusted to and front-seat supporting wallboard equal strength from 0,, make both form an integral body by the connection of bent cap.Have plurality of advantages:
1.. the rigidity of supporting and protection structure is big, and non-deformability is strong, and supporting effect is good;
2.. the retaining soil of supporting wallboard unites two into one with blocking water;
3.. the supporting and protection structure economic and reliable;
4.. pile tube is a prefabricated component, its intensity height, fast, the reliable in quality of speed of application;
5.. intensity is regulated supporting and is made that the intensity adjusting of whole supporting and protection structure is flexible, convenient, and adjustable range can be adjusted to and front-seat supporting wallboard equal strength from 0 greatly.
Description of drawings
Fig. 1 is a prefabricated prestressing pipe pile composite supporting of the present utility model structural plan schematic diagram, regulates supporting B comprising prefabricated prestressing pipe pile 1, stirring body 2, bent cap 3, composite support wallboard A, intensity.
The specific embodiment
Prefabricated prestressing pipe pile composite supporting wall structure of the present utility model comprises prefabricated prestressing pipe pile 1, stirring body 2; Stirring body 2 is between prefabricated prestressing pipe pile 1 side by side and in the tube core, adjacent prefabricated prestressing pipe pile 1 is connected as a single entity, form front-seat composite support wallboard A, there is intensity to regulate supporting B in the outside of composite supporting wall A, intensity is regulated stirring body 2 compositions that supporting B comprises prefabricated prestressing pipe pile 1 and is arranged in prefabricated prestressing pipe pile 1, and composite supporting wall A regulates supporting B with intensity and is connected by bent cap 3.The stirring body material stirs the back by cement, expansive soil, flyash and the soil body and forms.
The excavation of foundation pit degree of depth is 9.8m, adopts prefabricated prestressing pipe pile composite supporting wall structure to carry out pattern foundation pit supporting structure.The pile tube external diameter is 600mm.The clear spacing of front-seat supporting wallboard (A) is 400mm, and the clear spacing that intensity is regulated supporting B is 1400mm, and pile concrete C60, arrangement of reinforcement are 16 Φ 12.7.During making, adopt the deep-mixed pile machine that the soil body is stirred earlier, mix cement and swell soil simultaneously, stirring end, before the stirring body knot is hard, after with Static pressure pile driver prefabricated tubular pile being pressed into stirring body, using bent cap (3) that supporting wallboard A and intensity are regulated supporting B again and be connected as a single entity and form the composite support structure.
