Description

Well lid for water supply and drainage engineering

Technical Field

The utility model relates to a well lid for water supply and drainage engineering belongs to water supply and drainage engineering technical field.

Background

The water supply and drainage engineering refers to urban water supply systems and drainage systems (municipal water supply and drainage and building water supply and drainage), and is called water supply and drainage for short. The water supply and drainage engineering mainly comprises a water supply system and a drainage system. The drainage system is mainly a drainage pipeline, rain and sewage are shunted or are already implemented in most cities at present, and rain water and sewage are separated into different pipelines to be drained.

For the rainwater drainage system, a plurality of rainwater drainage wells are arranged along the drainage pipeline and are sealed by using well covers, when the rainfall is very large and rainwater drainage cannot be met only by a sewer opening, the well covers of the rainwater drainage wells are usually opened to assist in rainwater drainage. Otherwise, the well lid may be jacked up due to excessive water pressure, and cause danger. The safety protection is generally not carried out to current well lid below protection network etc. and prevents that passerby from dropping, even there is the protection network also to be the silk screen structure, and the silk screen is fixed below the well lid, can't dismantle easily, and when needs got into rainwater drainage well, the silk screen is a hindrance, influences smooth work. In addition, as the meshes of the screen are too dense, if impurities such as fallen leaves or plastics exist in rainwater, the meshes are blocked, and drainage is affected.

The existing well cover of the rainwater drainage well mouth for the water supply and drainage engineering has poor use effect.

Drawings

Fig. 1 is a schematic view when the manhole cover of the utility model is opened;

FIG. 2 is a schematic view of the outer support cylinder of the present invention;

the device comprises an outer supporting cylinder 1, an upper well cover 2, a lower protective net 3, a well cover stopping table 4, a protective net stopping table 5, a clamping block 6, a lifting hole 7, a countersunk head bolt 8 and a lifting block.

Detailed Description

The utility model discloses a well lid for plumbing engineering is the part that can use among the plumbing engineering, specific well lid for rainwater drainage well that says so. The present invention will be described in further detail with reference to the following drawings and specific embodiments:

as shown in fig. 1, the manhole cover comprises an outer supporting cylinder 1, and an upper manhole cover 2 and a lower protective net 3 which are respectively hinged with the outer supporting cylinder 1. Wherein, the upper well cover 2 is positioned at the upper side, the lower protective net 3 is positioned at the lower side, and the upper well cover 2 and the lower protective net 3 are distributed up and down. In order to conveniently open and close the upper well cover 2, a lifting hole 7 is usually required to be arranged at the other end of the upper well cover opposite to the hinge point, and the lifting hole is also a universal arrangement of the well cover. Go up well lid 2 and mainly play the protection and seal the effect, lower protection network 3 can carry out safety protection and play the effect of supplementary drainage when last well lid 2 is opened.

As shown in fig. 2, the support cylinder 1 has a circular cylindrical structure and is provided with a stepped hole therein. The shoulder hole of the inside of a support section of thick bamboo 1 can form the well lid and end platform 4 and protection network and end platform 5, and the well lid ends platform 4 and protection network and ends platform 5 and also arrange the setting according to upper and lower order, and consequently the diameter that the platform 4 was ended to the well lid is greater than the diameter that the platform 5 was ended to the protection network. When the manhole cover is in a closed state, the upper manhole cover 2 is pressed on the manhole cover stop table 4, and the lower protective net 3 is pressed on the protective net stop table 5.

The utility model discloses in having set up lower protection network 3, lower protection network 3 uses a plurality of steel wire welding formation that distribute with great ease, and lower protection network 3 has certain weight, can set up to 2.5 ~ 5 Kg. In specific implementation, the longitudinal steel wires and the transverse steel wires are uniformly arranged and spaced at the same distance, holes formed between the steel wires are large, rainwater can be guaranteed to fall, and even if leaves or other sundries fall, the rainwater cannot be greatly influenced. Specifically, the distance between adjacent steel wires is controlled to be between 8cm and 12 cm.

The utility model discloses well support section of thick bamboo 1 is the drum structure, and corresponding setting is gone up well lid 2 and lower protection network 3 and is also circular. Because the upper well cover 2 is positioned above the lower protective net 3, the diameter of the upper well cover 2 is larger than that of the lower protective net 3, and the normal opening and closing of the upper well cover and the lower protective net are ensured.

The utility model discloses in set up well lid 2 and lower protection network 3, both homoenergetic can the switching. In practical use, sometimes only the upper well cover 2 needs to be opened, sometimes the upper well cover 2 and the lower protective net 3 need to be opened at the same time, so that the upper well cover and the lower protective net can be connected together, rotated together and opened, and separated. The corresponding structure sets up to, sets up a pair of card fast 6 of fixing at the medial surface of last well lid 2, and lower protection network 3 can dismantle the card and fix in the card piece 6, and specifically can block in the card piece 6 through the steel wire card of lower protection network 3. If need open well lid 2 and lower protection network 3 in the lump, then directly open well lid 2, protection network 3 blocks with well lid 2 this moment and is in the same place, and the staff can directly enter into the sewer. If it is heavy rainy day, need open the well lid and assist the drainage, will go up the well lid 2 and open the back and take off protection network 3 from blocking in the piece 6 down this moment, make protection network 3 still hug closely the protection network and end platform 5 down, lower protection network 3 can prevent that the pedestrian from dropping to lower protection network 3 has certain weight, can not be washed away by the water. Preferably, the paired blocking blocks 6 are provided in two sets, which can ensure stable blocking of the lower protection net.

The utility model discloses a well lid needs to be fixed with the well wall, in order to guarantee the firm fixed of well lid, uses the bolt fixed with the wall of a well. Specifically, the end face of the well wall is fixed to the protective screening stop table 5 through the countersunk head bolt 8, the upper end face of the countersunk head bolt 8 sinks into the protective screening stop table 5, and the closing of the lower protective screening 3 cannot be affected.

The utility model relates to a well lid for water supply and drainage engineering through the lower protection network that sets up the stereoplasm steel wire and form, when the well lid need be opened in rainy day, can enough guarantee safety, can guarantee again that the rainwater falls smoothly. The lower protective net can be conveniently opened, so that the rainwater can smoothly enter the rainwater well when needed. The well lid has good use performance.
