Abstract

The utility model discloses a kind of inexpensive pit shafts, including pit shaft ontology, well lid support base, pipeline connection port；The pit shaft ontology is thin wall cylindrical pit shaft；The well lid support base is arranged in pit shaft ontology upper end；The cylinder face of the pit shaft ontology is equipped with the pipeline connection port in several perforation cylinder faces, it is characterised in that: is provided with several inclined grooves on the cylinder face length direction of the pit shaft ontology；The depth of the groove is the half of pit shaft ontology wall thickness；It is arranged in parallel between the groove；The width of the groove is less than the distance between adjacent two groove；The groove and the angle of pit shaft ontology bottom surface are A, 60 ° of 90 ° of < A <.The groove structure of the utility model pit shaft can substantially reduce the cost of concrete prefabricated pit shaft, and shaft structure ensure that the intensity of pit shaft not will receive large effect simultaneously, and soil can improve bigger support force by groove to pit shaft after installation, prevent from sinking.

Description

A kind of low cost pit shaft

Technical field

The utility model relates to cement wellbore technologies field more particularly to a kind of inexpensive pit shafts.

Background technique

In order to more efficiently build municipal well in urban construction, concrete prefabricated pit shaft is at essential production Product.Lead to underground piping by digging a hole on ground, installation cement pit shaft carries out the reinforcing at hole at hole, can be quickly and easily Complete the Preliminary Construction of municipal well.Well lid is installed at the top of cement pit shaft, guarantees safety and subsequent inspection.The barrel of cement pit shaft Pipeline connection port generally is offered, the connection or steering for connecting the pipelines such as water pipe, for pipeline.Cement pit shaft will be to top The well lid in portion provides support force, also to guarantee that side wall will not be damaged.The wall thickness of existing cement pit shaft is generally thicker, and barrel is smooth, Higher cost, and the time has been grown and has been easy to sink.

Utility model content

The purpose of this utility model is that in view of the deficiencies of the prior art mentioned above and to provide a kind of production simple, can be with The inexpensive pit shaft for preventing pit shaft sagging.

A kind of low cost pit shaft, including pit shaft ontology 1, well lid support base 2, pipeline connection port 3；The pit shaft ontology 1 is Thin wall cylindrical pit shaft；The well lid support base 2 is arranged in 1 upper end of pit shaft ontology；The cylinder face of the pit shaft ontology 1 is equipped with several The pipeline connection port 3 in a perforation cylinder face, it is characterised in that: be provided with several on the cylinder face length direction of the pit shaft ontology 1 Inclined groove 4；The depth of the groove 4 is the half of 1 wall thickness of pit shaft ontology；It is arranged in parallel between the groove 4；Institute The width for stating groove 4 is less than the distance between adjacent two groove 4；The groove 4 and the angle of 1 bottom surface of pit shaft ontology are A, 60 ° 90 ° of < A <.

Further, the distance between described adjacent two groove 4 is 1.2~2 times of 4 width of groove.

The utility model structure the utility model has the advantages that the design of groove reduces the cost of manufacture of cement pit shaft, pit shaft it is strong Degree not will receive large effect.Groove and pit shaft ontology bottom surface angle are greater than 60 °, reduce the manufacture difficulty of pit shaft ontology, More easily demould.The support force that groove can be provided by soil simultaneously is bigger, stronger after the installation of pit shaft ontology.

Specific embodiment

Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model is made further specifically It is bright.It should be appreciated that the embodiments of the present invention is not limited by the following examples, the utility model is done any Formal accommodation and/or change falls within scope of protection of the utility model.

The utility model discloses a kind of inexpensive pit shafts, as shown in Figure 1 and Figure 2, including pit shaft ontology 1, well lid support base 2, pipeline connection port 3；The pit shaft ontology 1 is thin wall cylindrical pit shaft；The well lid support base 2 is arranged in 1 upper end of pit shaft ontology； The cylinder face of the pit shaft ontology 1 is equipped with the pipeline connection port 3 in several perforation cylinder faces, it is characterised in that: the pit shaft ontology 1 Cylinder face length direction on be provided with several inclined grooves 4；The depth of the groove 4 is the half of 1 wall thickness of pit shaft ontology； It is arranged in parallel between the groove 4；The width of the groove 4 is less than the distance between adjacent two groove 4；The groove 4 Angle with 1 bottom surface of pit shaft ontology is A, 60 ° of 90 ° of < A <.

Embodiment one: the design of groove 4 reduces the cost of manufacture of cement pit shaft, and the intensity of pit shaft ontology 1 not will receive Large effect.Preferably 70 ° of groove 4 and 1 bottom surface included angle A of pit shaft ontology, effectively reduce the manufacture difficulty of pit shaft ontology 1, more It is easy demoulding.The support force that groove 4 can be provided by soil simultaneously is bigger, and pit shaft ontology 1 is stronger after installing, and is not easy down It falls into.Well lid support base 2 is used to support well lid, and multiple pipeline connection ports 3 are turned to for connecting pipe or to pipeline.

The foregoing is merely the implementation examples of the utility model, and therefore it does not limit the scope of the patent of the utility model, all It is equivalent structure transformation made based on the specification and figures of the utility model, is applied directly or indirectly in other correlations Correlative technology field similarly includes the scope of patent protection in the utility model.
