Abstract
A semicircular concrete composite sheet pile is characterized by mainly comprising a concrete pile body (1) with a semicircular section, a reinforcing mesh (2) and metal connecting structures (3), wherein the semicircular reinforcing mesh (2) is positioned in the concrete pile body (1); two sides of the semicircular reinforcing mesh are connected with the metal connecting structures (3) in a welding manner; and the connecting structures (3) used for being connected with the adjacent composite sheet piles adopt male and female matched structures. The semicircular concrete composite sheet pile fully combines the advantages of the metal reinforcing mesh and concrete, not only ensures that the ideal bending resistance identical to that of a steel sheet pile can be obtained, but also prevents the widespread corrosion problem of the steel sheet pile, provides an ideal slope protection material for long-term geological engineering, and is convenient to manufacture and low in cost.
Description
Technical field
The utility model relates to a kind of civil works steel sheet pile, especially a kind of material-saving shape sheet pile, specifically a kind of semicircle concrete slab stake.
Background technology
As everyone knows, steel sheet pile began in Europe to produce in 20 beginnings of the century, and rapidly all over the world particularly flourishing industrialized country be used widely.The 1950's, China in the railroad bridge cofferdam construction, introduces use by bridge office of the Ministry of Railways from the former Soviet Union first.Because it is be subjected to the influence of cheap land resources and manpower, domestic production is in space state substantially in addition, as the steel sheet pile of metal building material, still very slow with development in the application of China.Along with China's rapid economy development, all kinds of construction techniques quick, efficient, environmental protection are approved and are developed that in 20 end of the centurys, oneself has certain development the steel sheet pile application project of China.Because its special construction, thereby have unique advantage: high strength, light-duty, water isolating good; Durability is strong, reaches 20-50 application life; Reusable, generally can use 5-10 time; Environment protecting is remarkable, can significantly reduce the amount of fetching earth and concrete use amount in construction, effectively protects land resources; Function with stronger disaster relief and rescue, especially control flood, cave in, subside, in the rescue and relief work of drift sand, it is fast especially to take effect; Construction is simple, and the duration shortens, and construction cost is economized.
According to the knowledge of the applicant, steel sheet pile commonly used at present has H shape, U-shaped, Z-shaped and circular, it is and adopts sheet metal or metal pipe material clod wash or welding forming, need to use a large amount of metal material, and the manufacturing of metal material is a kind of high energy consumption industry, steel sheet pile need be placed for a long time underground application as a civil engineering part to some, can cause the waste of a large amount of metal material, time also can influence workmanship and life-span because of metal erosion after having grown, wherein common circular steel sheet pile directly uses after can directly utilizing existing steel pipe to be welded to connect ear, but this steel sheet pile exists the welding difficulty big, have only in actual the use that single face is stressed to cause unnecessary waste, it is few therefore to redesign a kind of metal material consumption, can be embedded in underground for a long time or water in, easily manufactured, the equipment less investment, NEW TYPE OF COMPOSITE sheet pile with obvious energy conservation and consumption reduction effects is the task of top priority.。
Summary of the invention
The purpose of this utility model is the syndeton welding difficulty that exists at the pipe steel sheet pile that has, need expend the problem of a large amount of metal material, and it is effective easily manufactured and can long-term mistake be embedded in semicircle concrete slab stake in the basis to design a kind of material-saving.
The technical solution of the utility model is:
A kind of semicircle concrete slab stake, it is characterized in that it mainly is made up of concrete pile body 1, steel mesh reinforcement 2 and the metal connecting structure 3 of cross section semicircular in shape, described semicircle steel mesh reinforcement 2 is arranged in concrete pile body 1, its both sides and metal connecting structure 3 are weldingly connected, the described structure that matches for male and female for the metal connecting structure 3 that links to each other with adjacent compound sheet pile.
When the side in the described metal connecting structure 3 was solid cylinder or hollow cylinder structure, opposite side was the circle structure of band opening.
Described metal connecting structure 3 is the vortex fit structure.
Described steel mesh reinforcement 2 be provided with protrude from the surface be used for to insert the concrete pile body to strengthen the reinforcement 4 of bonding strength.
The upper end of described concrete pile body 1 and/or lower end all add metal cap so that advance stake.
The lower end of described concrete pile body 1 structure triangular in shape.
The beneficial effects of the utility model:
The utility model can save energy great deal of investment, reduces the metal material use amount, is conducive to energy-saving and emission-reduction.
The utility model fully combines metal steel mesh reinforcement and concrete advantage, can guarantee to obtain the desirable anti-bending strength identical with steel sheet pile, can avoid the ubiquitous etching problem of steel sheet pile again, for long-term Geological Engineering provides desirable slop protection material.
The utility model is easily manufactured, and cost is low.It is a kind of desirable metal substitute device.
Description of drawings
Fig. 1 is perspective view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of semicircle concrete slab stake, it mainly is made up of concrete pile body 1, steel mesh reinforcement 2 and the metal connecting structure 3 of cross section semicircular in shape, and as shown in Figure 1, for guaranteed strength, the thickness of concrete pile body 1 is to be not less than 10 centimetres for good.In order to increase steel mesh reinforcement 2 and concrete bonding strength, can weld some insertion concrete pile bodies that are used for that protrude from the surface at steel mesh reinforcement 2 when specifically implementing and can be pin, awl with the reinforcement 4(that strengthens bonding strength, vertically also tiltable), described semicircle steel mesh reinforcement 2 is arranged in concrete pile body 1, its both sides and metal connecting structure 3 are weldingly connected, the described structure that matches for male and female for the metal connecting structure 3 that links to each other with adjacent compound sheet pile.When the side during concrete enforcement in the metal connecting structure 3 of described pipe body 1 both sides phase side can be solid cylinder or hollow cylinder structure, opposite side also can adopt the vortex fit structure for the circle structure of band opening, also can adopt common crotch structure.In order to increase the impact resistance of concrete composite pile, can all add metal cap so that advance stake in upper end and/or the lower end of concrete pile body 1 during concrete enforcement, in addition, enter fast in the ground in order to use, the lower end of sheet pile of the present utility model can be designed to taper or triangular structure, and traditional steel sheet pile is in order to reduce manufacturing cost, and the lower end is generally plane structure.
The utility model need not special-purpose clod wash equipment, therefore, reduced investment, easily manufactured, cost is low, has the good market competitiveness.
Can knit out dual-side and the metal connecting structure welding of semicircle steel mesh reinforcement 2 during manufacturing earlier, again steel mesh reinforcement is put into the U-shaped mould and poured into the concrete slurry, solidifying the metal cap that adds enterprising stake usefulness after the maintenance again at two ends can use, and both can adopt during use to impact stake and also can adopt static pressure to advance post.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
