Abstract

A precast reinforced concrete combined type septic tank comprises a plurality of precast reinforced concrete pipes, bottoms of which are sealed. Preformed holes are provided on the upper part and the lower part of sidewall of each of the concrete pipe. The septic tank is characterized in that adjacent precast reinforced pipes are connected through level communicating pipes between preformed holes; an upper port of each of the reinforced concrete pipes is provided with a cover board; an air vent is provided on the cover board. A water inlet and a water outlet are provided on the sidewall at both ends of the reinforced concrete pipe respectively. A flanged bend-shaped sucker is provided at the water outlet, respectively. An intake of the sucker is arranged inside the precast reinforced concrete pipe. The utility model has the advantages of short construction period, low cost, high strength, no leakage, small floor space, large capacity, flexible combination, effective treatment, easiness to be cleaned, and that water quality can reach environmental standard.

Description

Prefabricated reinforced concrete combined septic tank

Technical field

The utility model belongs to a kind of septic tank, particularly a kind of prefabricated reinforced concrete combined septic tank.

Background technology

Septic tank has played very important effect as the primary treatment facility of fecal sewage and other sanitary sewages at the aspects such as pollutant load that alleviate the drainage pipeline obstruction and reduce in the sanitary sewage.In recent years along with the fast development of urban construction and residential quarters, the city domestic sewage amount has been increased sharply several times, particularly in the biotope, because the imperfection of entire city sewage work and pumping equipment, the processing of the one-level of septic tank seems particularly important after the biotope draining goes out the family like this.But for many years owing to many-sided reason, this building fittings of septic tank does not obtain enough attention, makes the not little structures of this initial cost can not normally bring into play its effect.

The design of China's septic tank at present is divided into brick septic tank and reinforced concrete septic tank by its structure difference, septic tank is many based on brick in the building trade now, no matter be brick septic tank or reinforced concrete septic tank, all exist the construction period long, cost is high, be not suitable for the high speed development of modern construction engineering, floor space is big, dumb, changes the excrement weak effect, not the problem of easy cleaning.In addition, because the general Civil apartment construction of northern China mostly is completed before the Spring Festival, use immediately after drainage system unavoidably need be constructed in the winter time and hand over like this, in construction, often occur because grout, concrete does not reach before the design strength, the insulation measure does not reach the situation of requirement, make sand-cement slurry, concrete is endured cold, because impulsive force, factors such as the acid and alkali corrosion water consumption instability of water quality, temperature variation in the septic tank is also changed thereupon, by the time after thawing 1 year spring, some brick septic tank, brick mortar takes place loose, sewage stretcher seam seepage, serious even septic tank is collapsed, cause sewage normally not discharge, the basis of heavy corrosion buildings.

Summary of the invention

The purpose of this utility model is to solve the problems referred to above that prior art exists, provide a kind of construction period short, cost is low, intensity height, non-leakage, floor space is little, combination is flexible, capacity is big, change effective, the easy to clean of excrement, water quality can reach the prefabricated reinforced concrete combined septic tank of environmental protection standard.

The utility model is achieved in that the prefabricated reinforced concrete pipe that it has several bottoms to seal, be provided with pre-opened hole in each prefabricated reinforced concrete pipe side wall upper part and bottom, its special character is: link to each other by the level communicating pipe that is located between the pre-opened hole between the adjacent prefabricated reinforced concrete pipe, the cover plate that is equipped with suitable for reading at each prefabricated reinforced concrete pipe, cover plate is provided with venting hole, on the prefabricated reinforced concrete pipe sidewall that is positioned at the head and the tail two ends, be respectively equipped with water-in and water outlet, elbow shape suction pipe is installed at the water outlet place, and described suction pipe inlet is positioned at the prefabricated reinforced concrete pipe.

Above-mentioned prefabricated reinforced concrete combined septic tank, described prefabricated reinforced concrete pipe constitute by upper and lower two sections and are the tongue and groove connection between two sections, so that transportation and installation.

Advantage of the present utility model is: 1, construction period weak point, and an engineering can be used in general one day; 2, cost is low, is 1/3rd of brick septic tank; 3, intensity height, easy to leak not; 4, floor space is little, capacity is big, and combination flexibly, and is changeable, can deeply can be shallow; 5, can realize multiple-stage treatment to dirt in the septic tank, can increase the residence time of suspension dirt in septic tank, make the progressively sedimentation in the residence time of less suspended substance, make and flow out the outer sewage pollution degree reduction of septic tank, water quality reaches environmental protection standard, it is effective to change excrement, and easy to clean just needed cleaning once in 3～five years.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of tail end concrete pipe;

Fig. 3 is the upper and lower two sections junction synoptic diagram of concrete pipe.

Among the figure: 1-prefabricated reinforced concrete pipe, 2-water-in, 3-cover plate, 4-venting hole, 5-water outlet, 6-elbow, 7-communicating pipe, 8-communicating pipe.

Embodiment

As depicted in figs. 1 and 2, the prefabricated reinforced concrete pipe 1 that this prefabricated reinforced concrete combined septic tank has several bottoms to seal, the diameter of prefabricated reinforced concrete pipe 1 are 0.8～2.2m, and volume is 5～10m ³, present embodiment is an example with 4 concrete pipes, concrete pipe actual quantity is not limited by present embodiment, but is advisable with 4～10, with guaranteeing excrement effect.Be provided with pre-opened hole in each concrete pipe 1 side wall upper part and bottom, between the concrete pipe 1 by being inserted into the level communicating pipe 7 between the pre-opened hole, 8 link to each other successively, be placed with Steel Concrete cover plate 3 and smear reality the suitable for reading of each concrete pipe 1 with cement, on cover plate 3, be provided with venting hole 4, be positioned at head and the tail two ends concrete pipe 1 sidewall on be respectively equipped with water-in 2 and water outlet 5, be fitted with elbow shape suction pipe 6 at water outlet 5, described suction pipe 6 inlets are positioned at prefabricated reinforced concrete pipe 1, described

level communicating pipe

7,8 and suction pipe 6 all can adopt reinforced concrete prefabricatedly, and closed processes is made with cement in all junctions.

During installation, dig pit on the ground earlier, make concrete cushion, this prefabricated reinforced concrete combined septic tank is put into the hole, water-in 2, suction pipe 6 outlets are connected with sewer line, drainage pipeline respectively, fill out the hole with original soil or hair sand again at the end, hole.Sewage is entered by water-in 2 in the concrete pipe of head end, purifies through adjacent successively concrete pipe again, and throw out, water and suspended substance lay respectively at concrete pipe bottom, middle and upper part and top, and the clear water behind stage purification is sucked by suction pipe 6 inlets, discharges through drainage pipeline again.

Embodiment 2:
