Abstract
The utility model discloses a prefabricated concrete block for rolling a concrete arch dam for seaming. The prefabricated concrete block for rolling the concrete arch dam for seaming comprises a vertical concrete block (1) and a horizontal concrete block (2), wherein the vertical concrete block (1) and the horizontal concrete block (2) form an L shape; at least one grouting slot (3) is formed on the vertical concrete block (1); and anchor bar holes (4) are uniformly distributed in the horizontal concrete block (2). The prefabricated concrete block for rolling the concrete arch dam for seaming can significantly reduce the weight, is convenient to transport during construction, can reduce the labor intensity and can speed up a construction progress; rapid positioning during installation can be realized by matching the anchor bar holes and embedded bars and the installation is convenient; during concrete rolling construction, the prefabricated concrete block does not displace to cause damage to a grouting system; the prefabricated concrete block for rolling the concrete arch dam for seaming can also be prefabricated in advance and quickly assembled on a construction site, thereby not only ensuring effects of a seam, but also ensuring realization of full-section complete rolling and continuous rise and minimizing interference to the construction; and pipe holes, spline grooves and the like can be reserved as required in the prefabricating process, thereby facilitating the laying of the grouting system.
Description
Technical field
the utility model relates to a kind of precast concrete block that the rolled concrete arch dam becomes seam that is used for, and belongs to the rolled concrete arch dam and becomes the seam technical field.
Background technology
present rolled concrete arch dam becomes the seam technology to adopt dual mode usually: the one, construct when carrying out the rolled concrete arch dam earlier; And then artificial ditching slotting on the rolled concrete arch dam; Imbed the precast concrete form of rectangle, and then fill concrete becomes seam.This mode is unfavorable for bringing into play the advantage of rolled concrete rapid construction more greatly to the interference of storehouse face, is difficult for burying underground grouting system.The 2nd, before grinding concrete construction, the precast concrete with rectangle becomes the slit die board placing good earlier, and then carries out the grinding concrete construction operation.Because existing precast concrete becomes location and fastening devices are not set on the slit die plate, the location is inconvenient during installation, and template often is subjected to displacement during the concrete roller compaction construction, causes grouting system to destroy.Because the one-tenth slit die plate weight of rectangle is big, difficult is installed at the scene in addition.
Summary of the invention
The purpose of
the utility model is, provides a kind of weight lighter, is convenient to install and the precast concrete block that the rolled concrete arch dam becomes seam that is used for of locating.
The technical scheme of the utility model
a kind of precast concrete block that is used for rolled concrete arch dam one-tenth seam, precast concrete block comprises vertical concrete piece and horizontal concrete piece, vertical concrete piece and horizontal concrete piece constitute L shaped; Vertical concrete piece is provided with at least one grout groove, is evenly equipped with the dowel hole on the horizontal concrete piece.
In
aforementioned precast concrete block, said vertical concrete piece is provided with the inclined-plane with the interior angle place that is connected of horizontal concrete piece.
In
aforementioned precast concrete block, said grout groove is a half slot.
In
aforementioned precast concrete block, said precast concrete block is a reinforced concrete member, and concrete is the C20 concrete.
compared with prior art; The cross sectional shape of the precast concrete block of the utility model is L shaped; Become the slit die plate to compare with existing rectangle, carrying is convenient in significantly weight reduction under the situation that does not reduce intensity during construction; Can alleviate working strength of workers, accelerating construction progress; The utility model is provided with the dowel hole, can cooperate with embedded bar when installing and can position fast through the dowel hole, can conveniently install; Precast concrete block can not be subjected to displacement during the concrete roller compaction construction, causes grouting system to destroy.The utility model also can be prefabricated in advance, and assembling fast both can guarantee the effect of stitching at the construction field (site); Can guarantee the realization that the logical storehouse of full section is rolled, risen continuously again; Reduce interference to greatest extent, can reserve pipeline hole, keyway etc. as required when prefabricated, make things convenient for grouting system to bury underground construction.

Fig. 2 is the assembling sketch map.
Being labeled as in
accompanying drawing: the vertical concrete piece of 1-, the horizontal concrete piece of 2-, 3-grout groove, 4-dowel hole, 5-inclined-plane, 6-embedded bar.
The specific embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.
are as shown in Figure 1, and the precast concrete block that is used for rolled concrete arch dam one-tenth seam comprises vertical concrete piece 1 and horizontal concrete piece 2, and vertical concrete piece 1 is L shaped with horizontal concrete piece 2 formations; Vertical concrete piece 1 is provided with at least one grout groove 3, is evenly equipped with dowel hole 4 on the horizontal concrete piece 2.Vertical concrete piece 1 is provided with inclined-plane 5 with the interior angle place that is connected of horizontal concrete piece 2.Grout groove 3 is a half slot.Precast concrete block is a reinforced concrete member, and concrete is the C20 concrete.
The practical implementation process of the utility model
are as shown in Figure 1, and the precast concrete block that is used for rolled concrete arch dam one-tenth seam is with C20 concrete and bar pouring injection forming.The cross sectional shape of precast concrete block is L shaped.L shaped by a vertical concrete piece 1 and horizontal concrete piece 2 vertical connecting and composing; The height of vertical concrete piece 1 is 300 centimeters, and thickness is 100 centimeters, and the one-tenth seam one side of vertical concrete piece 1 is provided with two grout grooves 3; Grout groove 3 is semicircle; The radius of semicircle is 30 centimeters, and the center to center distance of two grout grooves 3 is 140 centimeters, and the end face of the top vertical concrete piece 1 of grout groove 3 center to center distance is 80 centimeters.The width of horizontal concrete piece 2 is 300 centimeters, and thickness is 80 centimeters, is evenly equipped with dowel hole 4 along its length on the horizontal concrete piece 2, and the aperture in dowel hole 4 is 20 centimeters a through hole, and dowel hole 4 is vertical with the bottom surface of horizontal concrete piece 2.Be provided with inclined-plane 5 at vertical concrete piece 1 with the interior angle place that horizontal concrete piece 2 is connected, inclined-plane 5 is 45 °.The limit of vertical concrete piece 1 of two back gauges on inclined-plane 5 and horizontal concrete piece 2 is respectively 140 centimeters.
During the assembling of the precast concrete block of
the utility model, as shown in Figure 2, two precast concrete blocks are symmetrical set, and the just synthetic circular hole in dowel hole 4 on two precast concrete blocks is used to bury underground grouting system.On dowel hole 4 be through on the embedded bar 6 on the concrete arch dam, two symmetrical precast concrete blocks position through the dowel hole 4 on the concrete arch dam, and can prevent that precast concrete block is subjected to displacement when carrying out the concrete roller compaction construction, cause grouting system to destroy.
