Abstract

The utility model discloses a combined drainage plate which is buried under the ground and is used for draining water. The utility model is composed of a water storage pipe and at least two drainage plates, wherein the drainage plates are fixedly connected with the pipe wall of the water storage pipe in the circumference in equal parts mode. A longitudinal through hole trough and a transverse through hole trough which are separated by a partition board are arranged in the drainage plate. A drainage hole which is communicated with the transverse through hole trough of the drainage plate is arranged on the pipe wall of the water storage pipe. The utility model can longitudinally drain water as well as transversely drain water, has the advantages of large drainage range, high efficiency and fast velocity, and is easy to connect to an external device. The utility model has the functions of preventing and resisting seepage and obstructing groundwater flow and can accelerate the consolidation of underground soil layer, and consequently, the bearing capacity of the ground can be markedly reinforced.

Description

Combined type band drain device

The utility model relates to a kind of underdrainage device, and particularly a kind of combined type band drain device belongs to the Foundation Design field.

Traditional band drain device is a single plate structure, has the longitudinal hole groove in the plate, utilizes the pore principle, makes underground water along rising and discharge ground on these vertical holes.The shortcoming of its existence mainly contains four aspects: the one, only can longitudinal drainage, and drainage efficiency is low, and speed is slow; The 2nd, the water that drains into plate upper end usually can or leak into undergroundly again along the ground gravity flow, causes secondary cycle; The 3rd, the veneer folk prescription is little to the draining scope; The 4th, be not easy to be connected with external equipment, be not easy to artificial control, do not reach higher vacuum.

The purpose of this utility model is, overcomes the shortcoming of existing single band drain device, and a kind of be convenient to connect external equipment, directed drainage efficiency height, combined type band drain device that scope is big are provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of combined type band drain device, has through-hole groove longitudinally in its band drain, be coated with filter screen on the plate, it is characterized in that forming by water pipe and at least two band drains, fixedly connected with the retaining tube wall in band drain circumference in equal parts ground, also have horizontal through-hole groove in the band drain, cross through hole groove and longitudinal hole groove are separated with dividing plate, have the drain hole that is communicated with band drain cross through hole groove on the retaining tube wall.

The utility model is organically combined band drain and water pipe, when it is embedded in below ground, can longitudinal drainage also can transverse drainage, the draining scope is big, the efficient height, speed is fast, and the water pipe structure is convenient to be connected with external equipment, is convenient to reach in the artificial control device higher vacuum, and the water that in time will drain in the pipe transfers out, accelerate underground soil consolidation, it is impervious and cut off the effect of underflow to play antiseepage, thereby strengthens load supporting ability of ground more significantly.

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

Fig. 1 is the utility model embodiment overall structure schematic perspective view.

Fig. 2 is the A-A cut-away view of Fig. 1.

Fig. 3 installs the water stopping cap schematic diagram additional for Fig. 1 embodiment.

As depicted in figs. 1 and 2, combined type band drain device is made up of water pipe 2 and four band drains 1 among the embodiment, fixedly connected with the tube wall of water pipe 2 in band drain 1 circumference in equal parts ground, have in the band drain 1 by dividing plate 12 separated through-hole grooves longitudinally 11 and horizontal through-hole groove 13, have the drain hole 21 that is communicated with band drain cross through hole groove 13 on the retaining tube wall.3 signals cover the filter screen on the band drain among the figure.

Be convenient to packed and transported and embedding and drainage effect is better for making the utility model, further feature is: 1, as shown in Figure 1, water pipe 2 adopts tenon groove structure to fixedly connected with band drain 1,23 are the tongue-and-groove on the retaining tube wall among the figure, 14 is the tenon of band drain one side, during assembling the tongue-and-groove on the tenon insertion retaining tube wall of band drain one side is got final product; 2, as depicted in figs. 1 and 2, axial distribution has drain hole 22 on the tube wall of water pipe 2, increases the ability to the pipe internal drainage, further can also cover one deck filter screen (not drawing among the figure) on water pipe among the embodiment, makes underground water enter drain hole 22 through filter screen; 3, as shown in Figure 3, have water stopping cap chute 15, be provided with water stopping cap 16 in the both sides, upper end of band drain 1, water stopping cap 16 advances along chute 15, be installed on the band drain, the water that drains into band drain 1 upper end is directly entered in the water pipe 2, prevent that more effectively the water that drains into ground from overflowing everywhere.Same Fig. 1 of all the other labels among Fig. 3.

Band drain quantity of the present utility model is generally 2-5, is applicable to the processing of various engineering ground, and for example grounds such as large-scale tall buildings, highway, bridge, oil tank foundation, airport, harbour are handled.
